Azure Bastion supports SCALABILITY for SSH/RDP Connections with the new Standard SKU

Azure Bastion is a fully managed PaaS service to secure access Azure VMs via SSH/RDP without the need for Internet connectivity on the selected VMs. Azure Bastion was released as part of the Microsoft Ignite 2019. As part of the ongoing Microsoft Inspire 2021, Microsoft has launched a new SKU for Azure Bastion called Standard.

Difference between Basic and Standard SKU

When you create an Azure Bastion instance Microsoft creates in the backend an optimized Azure VM that runs all the processes they are needed for Azure Bastion. This Azure VM is called a Instance and had some limitations. In general when you deploy the Azure Bastion Basic SKU Microsoft deploys two instances which supports 20-24 concurrent sessions which means each instance support 10-12 sessions.

The Standard SKU allows you to specify the number of instances called as host scalling.

Please note that when using an Azure Bastion Standard SKU, the AzureBastionSubnet size should be increased to a subnet size of approximately /26 or larger.

Only the Azure Portal allows to deploy an Azure Bastion Standard SKU with the host scalling feature, because the feature is in public preview.

Azure VM Best Practices

Last year Gregor Suttie and Richard Hooper launched the Azure Advent Calendar and I got to support with a session on Azure Bastion. This year they improved on the idea with the Festive Tech Calendar. I’m happy to be back with an article on Azure VM best practices. I hope you find the article helpful and I would appreciate feedback.

Over the past few months, I have conducted many customer workshops, designed and implemented Landing Zones, and migrated or placed VMs into Azure. One of the most common customer questions has been about best practices for Azure VMs to maximize performance and efficiency, minimize costs, increase security, and reduce management overhead. This article is based on my real-world experience and recommendations based on several Azure projects.

Azure Bastion now supports VNET Peering

Update – 12/2020

Azure Bastion is now available in West Germany Central.

Azure Bastion is a service to avoid deployment own Jumphosts and reach Azure VMs over the Management Ports (SSH and RDP) in a secure way without the need to assign Public IPs directly to Azure VMs.

Azure Bastion got a really big improvement and now supports Azure VNET Peering. This includes all VNET peering models, inside a single subscription and VNET peering across different subscriptions.

My upcoming Community engagements in 2nd half of 2020

These times are challenging and I hope everyone is safe and healthy. Normally we have a lot of in person community conference, but actually we move a lot of this community meetings to online meetings. The good thing is we have more time for our family and need lees time for driving and so on.

In the 2nd half of 2020 I have the honor to speak at the following events:

Azure Bonn Meetup

Our Azure Bonn Meetup is also running as an virtual event and we have planned some exiting topics:

Are you interested in holding a session at our Azure Bonn Meetup – that sounds great. Please use the Microsoft form to let us know about you and your session and we look forward to welcoming you. Session language can be German or English 🙂

Virtual Cloud Identity Summit 2020

And finally the virtual Cloud Identity Summit 2020. This is our first event and we will focus only on Cloud Identity topics. This idea came up from Thomas Naunheim and we are really happy to realize this conference. The first speakers with great topics are announced and there coming more. Did you interested in how to secure your Cloud Identitys – this conference is a must see.

Update 4 on 14/07/2021

Microsoft has announced a new Azure Bastion Standard SKU as part of the ongoing Microsoft Inspire 2021. The difference between Basic and Standard SKU and the deployment process are summarized in this article.

Update 3 on 16/05/2021

VNET peering support for Azure Bastion is now GA

Update 2 on 26/04/2021

I updated the article based on the latest information around Azure Bastion. One big announcement is the support for peered VNETs for Azure Bastion – this is also integrated in this article. Please feel free to share and comment 🙂

Azure Bastion is a new service to reaches Azure VMs in a secure way without needing a Jump host in the same VNET or to publish an Public IP for a VM. Many customers using Public IPs to reach VMs (Windows and Linux) in Test and Dev environment. Please avoid managing Azure VMs over a Public IP, this is unsecure – use Azure Bastion.

Azure Bastion is in public preview since end of June 2019. Azure Bastion is General Available (since Microsoft Ignite 2019) and many limitations are gone. This article will short introduce the service, the new features and how easy is it to enroll the service in the environment to reach Azure VMs (Windows or Linux) over a secure way.

So thanks Robert and Gregor for this great initiative.

I´m happy to contribute with a session about Azure Bastion. A secure way to access your Azure VMs without need for a Jump host or to bind a public IP-Address to a server.

Azure Bastion – Sicherer Azure VM Zugriff via SSH/RDP ohne Public IP

Update 1

11/10/2021 Artikel ĂĽberarbeitet und weitere Links angefĂĽgt. Follow the link to a refreshed article in english

Azure Bastion ist ein ganz neuer Service im Azure Universum, der den Remote Zugriff auf eure Azure VMs via RDP/SSH deutlich vereinfacht und absichert.

Azure Bastion Architecture by Microsoft Docs

Bisher gab es zwei Möglichkeiten, um sich zu Azure VMs via RDP oder SSH zu verbinden.

  1. Es besteht Zugriff auf das VNET, in dem die Azure VM liegt. Dazu war eine VPN Verbindung zum VNET notwendig oder ein Jump Host der in Azure ausgerollt wurde.
  2. Oder die Azure VM erhielt eine öffentliche IP-Adresse, um RDP oder SSH nach außen zu veröffentlichen. Damit einhergehend öffneten sich eine Menge Sicherheitslücken.

Mit Azure Bastion gibt es nun eine 3. Möglichkeit.

Azure Bastion wird als Platform-as-a-Service bereitgestellt und ermöglicht eine nahtlose Verbindung über das Azure Portal zur entsprechenden Azure VM. Durch diese Funktion sind beide oben genannten Möglichkeiten obsolet und ein direkter Zugriff auf Azure VMs, ohne Public IP, ist immer möglich. Azure Bastion stellt auf seine Art einen entsprechenden Jump Host im jeweiligen VNET bereit und benötigt seinerseits eine Public IP für die entsprechende Funktionalität.
