Modify ProxyAddresses of Office 365 users without Exchange Online

This posting is ~2 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

As part of a Office 365 tenant rebuild, I had to move a custom domain to the new Office 365 tenant. The old tenant was not needed anymore, and the customer had to move to a Non-Profit tenant for compliance reasons. So the migration itself was no big deal:

  • disable AzureAD sync
  • change UPN of all users
  • remove the domain
  • connect the domain to the new tenant
  • setup a new AzureAD sync
  • assign licenses
  • time for a beer

That was my, honestly, naive plan for this migration.

Disabling the AzureAD sync was easy. Even the change from ADFS to Password Hash Sync was easy. Changing the UPN for all users was a bit challenging, but the PowerSHell code in this article was quite helpful.

$users = Get-MsolUser -All | Where {$_.UserPrincipalName -like "*customdomain.tld"} | select UserPrincipalName 

foreach ($user in $users) {
 
   #Create New User Principal Name
   $newUser = $user.UserPrincipalName -replace "customdomain.tld", "customdomain.onmicrosoft.com"
 
   #Set New User Principal Name
   Set-MsolUserPrincipalName -UserPrincipalName $user.UserPrincipalName -NewUserPrincipalName $newUser
 
   #Display New User Principal Name
   $newUser
 }

But after this, I still was unable to remove the custom domain from the tenant. The domain was still referenced in the ProxyAddresses attribute, which was synced by the AzureAD sync…

Removing the domain from the users in the on-prem Active Directory was not solution. The users were already cloud-only because the sync was switched off. With this in mind my plan was to modify the cloud-only users in the tenant. To be honest: This solution worked in this specific case!

The customer was using Microsoft Teams Commercial Cloud trial licenses, so I had no Exchange Online to edit the proxy addresses. But luckily, the Exchange Online Management PowerShell Module was quite helpful.

Get-MailUser | Select -ExpandProperty emailaddresses | ? {$_ -like "*customdomain.tld"}

This line of code gave me an idea how many users were affected… quite a lot… With my colleague Claudia I quickly developed some dirty PowerShell code to remove all proxy addresses that included the custom domain.

$users = Get-MailUser -ResultSize Unlimited

foreach ($u in $users) {

    Get-MailUser -Identity $u.Alias |select -ExpandProperty emailaddresses | 
    ? {$_ -like "*customdomain.tld"} |
    % {Set-MailUser -Identity $u.Alias -EmailAddresses @{remove="$_"}}
     
}

It tool about 45 minutes to modify ~ 2000 users. After this, I was able to remove the domain and connect it to the new tenant.

This solution worked in my case. Another way might be using the AzureAD sync itself, masking out the custom domain and wait until the domain is removed from all proxy addresses. But I didn’t tested this.

MFA disabled, but Azure asks for second factor?!,b

This posting is ~2 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

I just had a Teams call with a customer to resolve a strange mystery about Azure MFA.

The customer called me and explained, that he has a user with Azure Multifactor Authentication (MFA) disabled, but when he logs in with this account, he is asked to setup MFA. He setup MFA and was able to login according to their Conditional Access policies.

The customer and I took a look into their tenant and checked a couple of things. The first thing the customer showed me was this screen:

As you can see, the MFA state for this user is “disabled” (german language screenshot). Then we tool a look using the MSOnline PowerShell module.

PS C:\Users\p.terlisten> $x = Get-MsolUser -UserPrincipalName user@domain.tld
PS C:\Users\p.terlisten> $x.StrongAuthenticationMethods

ExtensionData                                    IsDefault MethodType
-------------                                    --------- ----------
System.Runtime.Serialization.ExtensionDataObject     False OneWaySMS
System.Runtime.Serialization.ExtensionDataObject     False TwoWayVoiceMobile
System.Runtime.Serialization.ExtensionDataObject      True PhoneAppOTP
System.Runtime.Serialization.ExtensionDataObject     False PhoneAppNotification

The user has MFA enabled and the second factor is an authenticator app on his phone.

Schrödinger’s MFA

The mystery is not a mystery anymore if you take into account that the first screenshot is the screenshot of the Per-User MFA.

The customer is using Conditional Access, therefore Security Defaults are disabled for his tenant. Microsoft states:

If your organization is a previous user of per-user based Azure AD Multi-Factor Authentication, do not be alarmed to not see users in an Enabled or Enforced status if you look at the Multi-Factor Auth status page. Disabled is the appropriate status for users who are using security defaults or Conditional Access based Azure AD Multi-Factor Authentication.

What are security defaults?

Conditional Access, or enabled Security Defaults, will force a user to enroll MFA, even if the per-user MFA setting is set to “disabled”!

You have to disable Security Defaults, and you have to disable Conditional Access in order to get per-user MFA reflect the current state of MFA for a specific user.

Moving a small on-prem environment to Azure/ O365 – Part 2

This posting is ~3 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

A couple of days ago, I wrote about our first steps to move our on-prem stuff to Azure. This post will cover how we adopted Office 365 and how we have started with our Azure deployment.

Our first step into Office 365 was Microsoft Teams. We needed a solution for calls (audio/ video) and chat. We skipped Skype 4 Business and started with Microsoft Teams.

Microsoft 2020 (c)

Our Microsoft Teams deployment was pretty simple: We used our Microsoft IUR Office 365 E3 plans. Microsoft Azure AD Connect was quickly deployed and the Microsoft Exchange Hybrid Connection Wizard did the rest. Some weeks later we deployed ADFS/ ADFS Proxy. We used this setup over several months and it was pretty slick and was working flawless. At this point, we only used Teams, Planner and OneDrive 4 Business (SharePoint).

Some months went by until we decided to move to Azure.

Resource groups in Azure

You can imagine a resource group (RG) as a container that contains one or more resources, like VMs, NICs, SQL instances etc. The resource group can contain all the resources for the solution, or only those resources that you want to manage as a group.

First question: What do we need to deploy?

The answer was easy:

  • in sum 9 VMs
  • VPN gateway
  • Recovery Services Vault
  • Automation Account
  • Log Analytics Workspace

Second question: One or multiple resource groups?

An easy rule of thumb is, that a resource group should contain only resources that share the same life cycle and sponsor.

Third question: Who needs delegated priviledges to manage this stuff?

In our case there was no need to fine-graded RBAC. All of our technical staff has a personalized admin account and should be able to do whatever is necessary.

So we went for a single resource group.

Do yourself a favor and keep the recommended naming conventions in mind!

Site-2-Site VPN

To connect our on-prem network to Azure, we had to setup a Site-2-Site VPN. This was the first thing after creating our first resource group. We used a Gen 1 Basic VPN Gateway, which was sufficient for our needs (max 100 Mbit, no OpenVPN, no BGP).

Keep in mind to choose your networks and subnets wisely. If you need to deploy 9 VMs, don’t use 10.0.0.0/8. ;) In our case we added two network ranges with a single subnet in each network range. One for our server VMs, and a second subnet as gateway subnet.

VM Deployment

We deployed our VMs as B-Series VMs. A common mistake is to use the wrong VM size. Start small and right-size a VM if necessary. Most of our VMs are B2s (2 CPUs, 4 GB RAM). Only the Exchange (B4m), the management (B2ms) and the RDS server (B2ms) differ from this. This looks pretty small for Server 2019, but it is working pretty nice.

After deploying the VMs, we assigned static IP addresses to them. To our suprise most things in Azure are lacking proper IPv6 support. :( That hurt a lot.

For most VMs we used Standard HDDs instead of SSDs. Even for your file server, because the bottleneck is not the disk, it is the connection between clients and server. Beside this, we used managed disks for all VMs, and we deployed a second disk for data if necessary (Exchange, domain Controller, file server etc.).

If a server had a DNAT in our on-prem network, we deployed a public IP, and secured the access to it.

All VMs are connected to the same Network Security Group (NSG), which we use to get control over what a VM can reach, and who can access a VM.

Server Migration

Over a couple of days we moved more and more services to Azure, starting with our Domain Controllers, PKI and file services. These were low hanging fruits. The file server was easy because we already had a DFS namespace in place, so all we had to do were to change the DFS Links and point them to the new file server. The data was copied by using DFS replication.

DHCP was moved to our on-prem firewall. A printserver was not necessary any more. Windows Updates were switched back to download from Microsoft and Delivery Optimization.

The applications that were running on our Linux and Windows application server were also easy to migrate. After a couple of days we had our server workload running on Azure.

To get our ERP running, we deployed a single RDS host (quick deployment), and deployed our ERP as a remote app. It was too slow to use it over the VPN. Unfortunately the application lacks a proper database backend. :/ But as a remote app, it is working pretty good.

A bigger challenge was Exchange, but not because of the mailbox migrations.

Exchange Online

The migration to Exchange Online was pretty simple. Since our first HCW run, we used the central mail transport, so that all mails are received and sent by our on-prem mail gateway.

The mailbox migration was pretty easy and we had zero issues. Then we tried to switch the mail transport from central of Exchange Online. This was flawless too… except the fact, that our ticket system was unable to send e-mails.

Our ticket system relays its mail over our Exchange server. After switching the mail server in our ticket system to the new Azure based VM, the mails stuck in the outbound queue, even if the server tried to send the mail to our on-prem mail gateway. This quote from Microsoft explains the whole problem:

Starting on November 15, 2017, outbound email messages that are sent directly to external domains (such as outlook.com and gmail.com) from a virtual machine (VM) are made available only to certain subscription types in Microsoft Azure. Outbound SMTP connections that use TCP port 25 were blocked. (Port 25 is primarily used for unauthenticated email delivery.)

This change in behavior applies only to new subscriptions and new deployments since November 15, 2017.

Source: Microsoft

This is the case for MSDN, Azure Pass, Azure in Open, Education, BizSpark, and Free Trial subscriptions!

If you created an MSDN, Azure Pass, Azure in Open, Education, BizSpark, Azure Sponsorship, Azure Student, Free Trial, or any Visual Studio subscription after November 15, 2017, you’ll have technical restrictions that block email that’s sent from VMs within these subscriptions directly to email providers. The restrictions are done to prevent abuse. No requests to remove this restriction will be granted.

If you’re using these subscription types, you’re encouraged to use SMTP relay services, as outlined earlier in this article or change your subscription type.

Source: Microsoft

We accelerated our migration and disabled the central mail transport earlier than planned. Then we configured our Linux application server to authenticate against Exchange Online using SMTP Auth and SMTP Submission (587/tcp). For incoming mails, the mails are routed to the application server using a Exchange Online connector and a transport rule which matches to specific mail addresses.

The Azure based Exchange VM is only needed because we still have an Azure AD Connect running. Microsoft has planned to replace this by a new solution. And until this, we will run this Exchange 2016 in Azure. But it is not part of our mail flow.

Moving Azure AD Connect & decommissioning ADFS

Because we had to get rid of the ADFS server and ADFS Proxy, we deployed Pass-Through Authentication and Seamless SSO. Then we decommissioned the ADFS setup.

Moving Azure AD Connect was a bit quirky. We had conditional access already in place and the Azure AD Connect setup was unable to handle this. The synchronisation account was unable to sync, because it ran into a MFA request. We optimized our policies and got this sorted out.

Decommissioning old stuff

Whenever we moved a service successful to Azure, we switched off the on-prem server, and modified our documentation to reflect the made changes. At the end, we were able to switch off three of our four ESXi hosts. A last ESXi Host is still running for our Horizon View deployment and our firewall.

Next steps

The next post will cover how we automated this, how we do backups and whatever you’re interested in. Leave a comment! :)

Moving a small on-prem environment to Azure/ O365 – Part 1

This posting is ~3 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

It was a bit quiet here due to the current COVID 19 pandemic. But now I’m back with a pretty interesting story on how my colleagues and I moved most of our on-prem server stuff to Microsoft Azure and Office 365.

Microsoft 2020 (c)

It all started with the COVID19 lockdown in Germany in March 2020. We moved into our home offices after setting up a small VMware Horizon View deployment to access our PCs using physical View Agents and manual desktop pools. Most projects were stopped, and we did most of our work remote. No lay-offs or short-time work.

We were running a small VMware vSphere cluster for a couple of years. Nothing fancy: Two HPE ProLiants, vCenter, two DCs, File-/ Printserver, WSUS, Exchange, Linux maschines for web services, Sophos UTM, a pfSense, View Connection Server, UAG, ADFS/ ADFS Proxy, PKI etc. In sum 18 VMs on two hosts, some VLANs with firewalls in between etc. We were running Exchange 2016, AzureAD Sync, Exchange Hybrid, but we only used Microsoft Teams from our Office 365 deployment. Veeam Backup & Replication was used for backups, a backup copy to a NAS and some Robocopy jobs that moved Veeam Backups to USB drives for DR. Everything was pretty simple and designed to work without much operations. Our focus is on our customers, not on our internal IT. It was stable, secure and pretty slick.

In March 2020 we asked “What if?”. What if we lose our offices due to a fire (we are located in a bigger office building and we had a couple of fire alarms this year due to remodeling work). How can we work if your DSL line is cut? How can we get our backups offsite? How can we modernize our IT withtout big invests? Money, that we don’t spend on our internal IT can given to our employees. ;) (By the way, that’s the same reason why we try to drive smaller and more efficient cars…).

We developed a couple of ideas, including new servers, storage etc. and put that stuff into a datacenter. But in the end, we decided to move most of our stuff to Microsoft Azure and Office 365.

I want to share some of the things we have learned on the road to Azure.

Initial assessment

We used the Azure Migrate Server Assessment tool to assess our vSphere environment. We wanted to get a ball park on how we had to size the VMs. We knew, that we wont need to migrate all VMs. For example our virtual pfSense firewall, the vCenter, the Sophos UTM or our ADFS setup were not planned to migrate.

After the first assessment, we started to play around the the Azure pricing calculator. Just to get an idea on how different VM sizes affect the costs.

Subscription

As a Microsoft partner, we were able to use our internal user rights (IUR) for Microsoft Office 365 and Azure. Microsoft offers us 25 Office 365 E3 plans and a 6000 US-$ budget for Azure (Azure Sponsorship Subscription). Our plan was to stretch the Azure budget over 12 months, so that we don’t have additional costs until we re-apply for our Microsoft partnership. Starting with 6000 US-$ Azure budget, it makes ~16 US-$ per day for our complete Azure deployment.

Sizing

Now, as we knew that we have 16 US-$ per day, we planned our Azure deployment. First of all, we planned the number of VMs. We had 18 VMs on-prem, and we managed to get down to 9 VMs.

  • two Domain Controller
  • PKI
  • Fileserver
  • Management Server
  • Remote Desktop Host (all-in-one Deployment)
  • Ticket System
  • SQL/ App server
  • Exchange 2016 for Hybrid Deployment

The View Connection Servers and UAG are still running on-prem. Our virtual pfSense will be moved to a WatchGuard Firebox soon. Sophos UTM and ADFS are gone. A dedicated WSUS server is not necessary any more, we moved back to simple Windows Update and Delivery Optimization.

Instead of D-Series VMs, we decided to go for B-Series VMs. The main reason for this were costs, but today I can say: The performance is quite good. I can’t see any reason for us to move to D-Series.

To connect to our Azure deployment, we had to setup Site-2-Site VPN. We deployed a simple Gen1 Basic SKU VPN Gateway. We had no need for more than 100 Mbit (we’re using a 50/10 VDSL at our office location), BGP or zone redundancy.

Instead of Standard SSD or Premium SSD storage, most of our VMs are using simple Standard HDD storage.

Backups are kept in a Recovery Services Vault with pretty simple polices. Either a VM needs to be current, in this case we keep 7 restore points, or we might need to keep more restore points. In this case we keep 7 daily, 5 weekly, 12 monthly and 3 yearly restore points. And this is only the case for our fileserver.

Additional cost savings

But with this setup we would not get under 16 US-$ a day. :( So we took another approach to break the mark: We shut down VMs at night and at the weekends! It took a bit until my colleagues and I get used to this. Nobody wants to shut down servers without a good reason.

But: We are currently at 18 US-$ per workday, and 10 US-$ for saturday and sunday. Everything, except domain controllers and ticket system, is shutdown at night and on the weekends.

We are using an Automation Account with some simple scripts and schedules to shutdown VMs and start them again.

What’s next?

The next blog post will be around how we planned the usage of Office 365, and how we started with Azure.

Once in a year: How to update TLS certificates on ADFS server and proxies

This posting is ~3 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

You might got this news some days ago: Starting with September 1, 2020, browsers and devices from Apple, Google, and Mozilla will show errors for new TLS certificates that have a lifespan greater than 398 days. Due to this move from Apple, Google and Mozilla, you have to deal with the replacement of certificates much more often. And we all know: Replacing certificates can be a real PITA!

Bild von skylarvision auf Pixabay

Replacing TLS certificates used for ADFS and Office 365 can be a challenging task, and this blog post will cover the neccessary steps.

ADFS Server

The first service, for which we will replace the certificate, is the ADFS server, or the ADFS server farm. At this point it is important to understand that we are dealing with two different points to which the certificate is bound:

  • the ADFS service communications certificate, and
  • the ADFS SSL certificate

The first step is to replace the service communication certificate. After importing the certificate with private key, you need to assign “read” permission to the ADFS service account. Right click on the certificate, then “All Tasks” > “Manage Private Keys”.

Make sure to import the certificate on all farm servers! Next step: Start the ADFS management console on the primary node. Select “Certificates” and then “Select service communication certificate” on the right window pane.

Now we have successfully replaced the service communication certificate. But we are no finished yet! Now we have to set the ADFS SSL certificate. Depending on your OS, you have to run the PowerShell command on the primary node. If your are running Windows Server 2012 R2 or older, you have to run the PowerShell command on EVERY ADFS farm server!

You can get the certificate thumbprint using the Get-AdfsSslCertificate command. Set the ADFS SSL certificate with

Set-AdfsSslCertificate -Thumbprint 07B3DFE31E020BFC3F3BDF1A0F61807223DBF125

Then restart the ADFS service.

Restart-Service adfssrv

ADFS Proxies

In most cases you will have one or more ADFS proxies in your DMZ. The ADFS proxy is nothing more than a Web Application Proxy (WAP) and therefore the PowerShell commands for WAP will be used.

First of all: Import the new certificate with the private key on all ADFS proxies, and then get the certificate hash of the new certificate. Then open an elevated PowerShell on each proxy.

Set-WebApplicationProxySslCertificate -Thumbprint 07B3DFE31E020BFC3F3BDF1A0F61807223DBF125

Then we have to re-establish the trust between the proxies and the primary ADFS farm server. You will need the local (!) administrator account of the primary farm server.

$cred = Get-Credential
Install-WebApplicationProxy -FederationServiceTrustCredential $cred -CertificateThumbprint 07B3DFE31E020BFC3F3BDF1A0F61807223DBF125 -FederationServiceName adfs.domain.tld

The last step is to update thefederated trust with Office 365.

Update the federated trust with Office 365

To update the federated trust with Office 365, you will need the Windows Azure Active Direcotry Module for Windows PowerShell and an elevated PowerShell. Connect to Office 365 and update the federated trust:

$cred = Get-Credential
Connect-MsolService -Credential $cred
Update-MSOLFederatedDomain –DomainName domain.tld

That’s it! Bookmark this page and set a calendar entry on today +12 months. :)

Passed Microsoft exam AZ-103 – Azure Administrator Associate

This posting is ~3 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

Six weeks ago, I passed the Microsoft AZ-103 exam and earned the Azure Administrator Associate. A last minute pass, because AZ-104 was already launched. But better late than never. I had to re-schedule the exam a couple of times because the test center was closed due to COVID19.

The Azure Administrator Associate is a Administrator-role certification and it is all about implementing, managing and monitoring the Azure identity, governance, storage, compute, and virtual network solutions.

The exam covers a couple of topics and you should have knowledge and hands-on experience in administering Azure services using the Azure Portal, PowerShell, Azure CLI, and Azure Resource Manager templates.

Your knowledge is tested over a broad band of topics. These topics are:

  • Manage Azure identities and governance
  • Implement and manage storage
  • Deploy and manage Azure compute resources
  • Configure and manage virtual networking
  • Monitor and back up Azure resources

How to prepare for the exam

Fortunately I have a monthly Azure credit which I can use to gain new skills. I used these Azure credit together with the Microsoft Learning Path for AZ-103 (now 104).

It is pretty important no only to focus on VMs, storage or networking. Web Apps was one of my blind spots, and I had to get my head around it. Azure identities and governance is not so hard, if you are already familiar with Office 365.

I learned a lot from the Microsoft Documentation for Azure, and I was really impressed how much I was able to find, read and learn from there.

Next stop: Microsoft Certified: Azure Solutions Architect Expert

Microsoft has announced to retire all remaining exams associated with Microsoft Certified Solutions Associate (MCSA), Microsoft Certified Solutions Developer (MCSD), Microsoft Certified Solutions Expert (MCSE) on January 31, 2021, so the role-based certifications introduced in September 2018 are the way to go.

I’m currently holding a MCSE for Core Infrastructure and one for Productivity. Based on this, the Azure Solutions Architect Expert is the next step for me.

Azure PowerShell vs. Azure RM PowerShell

This posting is ~5 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

In 2014, Microsoft announced the Azure Preview Portal, which was going GA in December 2015. Since January 8, 2018, the classic Azure Portal is turned off. The “Preview Portal” was more than a facelift. The classic Azure Portal was based on the Service Management mode, often called the “classic deployment model”, whereas the new Azure Portal uses the Resource Manager model. Azure Service Management (ASM) and Azure Resource Management are both deployment models. The Resource Manager model eases the deployment of complex setups by using templates to deploy, update and manage resources within a resource group as a single operation.

Azure PowerShell vs. Azure RM PowerShell

Different deployment models require different tools. Because of this, Microsoft offers two PowerShell modules for Azure. Depending on your deployment type, you have to use the Azure or AzureRM module. Both can be installed directly from the PowerShell Gallery using Install-Module -Name Azure or Install-Module -Name AzureRM .

Connect to Azure

Depending on the used module, the ways to connect to Azure differ.

Module AzureRM

PS C:\Users\p.terlisten> Connect-AzureRmAccount -Subscription 37cbb19b-cc7f-402a-xxxx-yxcvbnmasdfg


Account          : patrick@blazilla.de
SubscriptionName : vcloudnine Azure Lab
SubscriptionId   : 37cbb19b-cc7f-402a-xxxx-yxcvbnmasdfg
TenantId         : 2795c72a-aad7-404e-xxxx-yxcvbnmasdfg
Environment      : AzureCloud


PS C:\Users\p.terlisten>

You will notice, that AzureRM sessions does not persist between PowerShell sessions. This behaviour differs from Add-AzureAccount . But you can save and load your AzureRM session once you are connected.

PS C:\Users\p.terlisten> Save-AzureRmContext -Path X:\Secure\azurerm.json
PS C:\Users\p.terlisten> Import-AzureRmContext -Path X:\Secure\azurerm.json

Module Azure

PS C:\Users\p.terlisten> Add-AzureAccount

Id                  Type Subscriptions                           Tenants
--                  ---- -------------                           -------
patrick@blazilla.de User 37cbb19b-cc7f-402a-xxxx-yxcvbnmasdfg... {2795c72a-aad7-404e-xxxx-yxcvbnmasdfg}

Stop using your work email for your Microsoft account

This posting is ~6 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

Microsoft two different logins for their services:

  • Microsoft Account (former Live ID)
  • work or school account (Azure AD)

Both are located in different directories. The Microsoft account is located in another user database at Microsoft, as a work or school account. Latter are located in a Azure AD, which is associated with a customer. Both account types are identified using the email address. Microsoft accounts are used for service like Skype, OneDrive, but also for the Microsoft Certified Professional portal. Work or school accounts are mainly used for Office 365 and Azure.

You can use your work email address for your Microsoft account, until someone creates an Azure AD, and a work or school account with the same email address is created. From this point, your login experience with the different Microsoft services will getting worse. The main problem is, that Microsoft tries to find the given account in one of their directories, and it seems that they prefer Azure AD. So the login will work, but the content of the user profile will be different, because it’s a different account.

This is a screenshot from the new login screen. As you can see, there is no way to choose if you wish to login with a work/ school or Microsoft account.

This is the old login experience, where you can choose between work/ school and Microsoft account.

Sign in to Microsoft Azure

Patrick Terlisten/ www.vcloudnine.de/ Creative Commons CC0

Microsoft calls this an AzureAD and Microsoft account overlap, and they identified this as an issue. As a result, Microsoft denies the creation Microsoft accounts using a work or school email addresses, when the email domain is configured in Azure AD. Microsoft has published a blog post to address this issue: Cleaning up the #AzureAD and Microsoft account overlap

Because of this, you should avoid using your work email address for your personal Microsoft account. Even if this Microsoft account is linked to your MCP/ MCSE certifications. It is not a problem to use your personal Microsoft account, with your personal email address, for your certifications. And it is not a problem to link this account to a Microsoft partner account (as in my case).

Maybe it will be possible to merge Microsoft and work/ school accounts someday. There is an ongoing discussion about this since 2013 (Merge office365 and live accounts that use the same email address).

To remove your work or school email address from your personal Microsoft account, follow the instructions in this support artice (Rename your personal account).

Hell freezes over – VMware virtualization on Microsoft Azure

This posting is ~6 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.
Update

On November 22, 2017, Ajay Patel (Senior Vice President, Product Development, Cloud Services, VMware) published a blog post in reaction to Microsofts announcement (VMware – The Platform of Choice in the Cloud). Especially these statements are interesting:

No VMware-certified partner names have been mentioned nor have any partners collaborated with VMware in engineering this offering. This offering has been developed independent of VMware, and is neither certified nor supported by VMware.

and

Microsoft recognizing the leadership position of VMware’s offering and exploring support for VMware on Azure as a superior and necessary solution for customers over Hyper-V or native Azure Stack environments is understandable but, we do not believe this approach will offer customers a good solution to their hybrid or multi-cloud future.

Looks like VMware is not happy about Microsofts annoucement. And this blog post clearly states, that VMware will not partner with VMware to bringt VMware virtualization stack on Azure.

I don’t know if this is a wise decision of VMware. The hypervisor, their core product, is a commodity nowadays. We are taking about a bare-metal solution, so it’s not different from what VMware build with AWS. It’s more about how it is embedded in the cloud services and cloud control plane. If you use VMware vSphere, Horizon and O365, the step to move virtualization workloads to VMware on Azure is smaller, than move it to AWS.

On November 23, 2017, the register published this interesting analysis: VMware refuses to support its wares running in Azure.

Original post

Yesterday, Microsoft announced new services to ease the migration from VMware to Microsoft Azure. Corey Sanders (Director of Compute, Azure) posted a blog post (Transforming your VMware environment with Microsoft Azure) and introduced three new Azure services.

Microsoft Azure

Microsoft/ microsoft.com

Azure Migrate

The free Azure Migrate service does not focus on single server workloads. It is focused on multi-server application and will help customers through the three staged

  • Discovery and assessment
  • Migration, and
  • Resource & Cost Optimization

Azure Migrate can discover your VMware-hosted applications on-premises, it can visualize dependencies between them, and it will help customers to create a suitable sizing for the Azure hosted VMs. Azure Site Recovery (ASR) is used for the migration of workloads from the on-premises VMware infrastructure to Microsoft Azure. At the end, when your applications are running on Microsoft Azure, the free Azure Cost Management service helps you to forecast, track, and optimize your spendings.

Integrate VMware workloads with Azure services

Many of the current available Azure services can be used with your on-premises VMware infrastructure, without the need to migrate workloads to Microsoft Azure. This includes Azure Backup, Azure Site Recovery, Azure Log Analytics or managing Microsoft Azure resources with VMware vRealize Automation.

But the real game-changer seesm to bis this:

Host VMware infrastructure with VMware virtualization on Azure

Bam! Microsoft announces the preview of VMware vSphere on Microsoft Azure. It will run on bare-metal on Azure hardware, beside other Azure services. The general availability is expected in 2018.

My two cents

This is the second big announcement about VMware stuff on Azure (don’t forget VMware Horizon Cloud on Microsoft Azure). And although I believe, that this is something that Microsoft wants to offer to get more customers on Azure, this can be a great chance for VMware. VMware customers don’t have to go to Amazon, when they want to host VMware at a major public cloud provider, especially if they are already Microsoft Azure/ O365 customers. This is a pretty bold move from Microsoft and similar to VMware Cloud on AWS. I’m curious to get more details about this.

Secure your Azure deployment with Palo Alto VM-Series for Azure

This posting is ~6 years years old. You should keep this in mind. IT is a short living business. This information might be outdated.

When I talk to customers and colleagues about cloud offerings, most of them are still concerned about the cloud, and especially about the security of public cloud offerings. One of the most mentioned concerns is based on the belief, that each and every cloud-based VM is publicly reachable over the internet. This can be so, but it does not have to. It relies on your design. Maybe that is only a problem in germany. German privacy policies are the reason for the two german Azure datacenters. They are run by Deutsche Telekom, not by Microsoft.

Azure Virtual Networks

An Azure Virtual Network (VNet) is a network inside the public Azure cloud. It is isolated from the underlying infrastructure and it is dedicated to you. This allows you to fully control IP addressing, DNS, security policies and routing between subnets. Virtual Networks can include multiple subnets to reflect different security zones and/ or multi-tier designs.  If you want to connect two or more VNets in the same region, you have to use VNet peering. Microsoft offers an excellent documentation about Virtual Networks. Because routing is managed by the Azure infrastructure, you will need to set user-defined routes to push traffic through a firewall or load-balancing appliance.

Who is Palo Alto Networks?

Palo Alto Networks was founded by Nir Zuk in 2005. Nir Zuk is the founder and CTO of Palo Alto Networks. He is still leading the development. Nil Zuk is a former employee of CheckPoint and NetScreen (was acquired by Juniper Networks). His motivation to develop his vision of a Next Generation Firewall (NGF) was the fact, that firewalls were unable to look into traffic streams. We all know this: You want that your employees can use Google, but you don’t want them to access Facebook. Designing polices for this can be a real PITA. You can solve this with a proxy server, but a proxy has other disadvantages.

Gartner has identified Palo Alto Networks as a leader in the enterprise firewall since 2011.

I was able to get my hands on some Palo Alto firewalls and I think I understand why Palo Alto Networks is noticed as a leader.

VM-Series for Microsoft Azure

Sometimes you have to separate networks. No big deal when your servers are located in your datacenter, even if they are virtualized. But what if the servers are located in a VNet on Azure? As already mentioned, you can create different subnets in an Azure VNet to create a multi-tier or multi-subnet environment. Because routing is managed by the underlying Azure infrastructure, you have to use Network Security Groups (NSG) to manage traffic. A NSG contains rules to allow or deny network traffic to VMs in a VNet. Unfortunately a NSGs can only act on layer 4. If you need something that can act on layer 7, you need something different. Now comes the Palo Alto Networks VM-Series for Microsoft Azure into play.

The VM-Series for Microsoft Azure can directly deployed from the Azure Marketplace. Palo Alto Networks also offers ARM templates on GitHub.

Palo Alto Networks aims four main use-cases:

  • Hybrid Cloud
  • Segmentation Gateway Compliance
  • Internet Gateway

The hybrid cloud use-case is interesting if you want to extend your datacenter to Azure. For example, if you move development workloads to Azure. Instead of using Azures native VPN connection capabilities, you can use the VM-Series Palo Alto Networks NGF as IPSec gateway.

If you are running different workloads on Azure, and you need inter-subnet communication between them, you can use the VM-Series as a firewall between the subnets. This allows you to manage traffic more efficiently, and it provides more security compared to the Azure NSGs.

If you are running production workloads on Azure, e.g. a RDS farm, you can use the VM-Series to secure the internet access from that RDS farm. Due to integration in directory services, like Microsoft Active Directory or plain LDAP, user-based policies allow the management of traffic based on the user identity.

There is a fourth use-case: Palo Alto Networks GlobalProtect. With GlobalProtect, the capabilities of the NGF are extended to remote users and devices. Traffic is tunneled to the NGF, and users and devices will be protected from threats. User- and application-based policies can be enforced, regardless where the user and the device is located: On-premises, in a remote location or in the cloud.

Palo Alto Networks offers two ways to purchase the VM-Series for Microsoft Azure:

  • Consumption-based licensing
  • Bring your own license (BYOL)

The consumption-based licensing is only available for the VM-300. The smaller VM-100, as well as the bigger VM-500 and VM-700, are only available via BYOL. It’s a good idea to offer a mid-sized model with a consumption-based license. If the VM-300 is too big (with consumption-based licensing), you can purchase a permanent license for a VM-100. If you need more performance, purchasing your own license might be the better way. You can start with a VM-300 and then rightsize the model and license.

All models can handle a throughput of 1 Gb/s, but they differ in the number of sessions. VM-100 and 300 use D3_v2, the VM-500 and VM-700 use D3_v2 instances.

Just play with it

Just create some Azure VM instance and deploy a VM-300 from the marketplace. Play with it. It’s awesome!
