  1. Intro In this blog post I will describe a way to implement an architecture that includes a private Azure Kubernetes Service (AKS) Cluster by using Bicep, a declarative language for describing and deploying Azure resources. According to project’s page on GitHub, Bicep is a Domain Specific Language (DSL) for deploying Azure resources declaratively and It aims to drastically simplify the authoring experience with a cleaner syntax, improved type safety, and better support for modularity and code re-use. The control plane or API server, in a fully private AKS cluster, has internal IP address and it communicates with the node pools through the private network, by leveraging the technology of Azure Private Link service. Furthermore, there is no need for the worker nodes to have a public IP assigned to a standard loadbalancer for egress the traffic as we are able to redirect the egress path through a Network Virtual Appliance or Azure Firewall. In a nutshell, a fully private AKS cluster does not expose or use any public IP. References The initial idea to create a Bicep script that deploys an architecture like the one mentioned in the architectural diagram section, was taken from the following articles: Baseline architecture for an Azure Kubernetes Service (AKS) cluster Fully private AKS clusters — without any public ips — finally! Create a “Fully private” AKS infrastructure with Terraform Architectural Diagram Bicep script The sources can be found at the following GitHub repository https://github.com/vakappas/private-aks-bicep The main Bicep script that deploys the architecture that is shown in the diagram, follows the modular approach and it has ‘subscription’ as its target scope. // set the target scope to subscription targetScope = 'subscription' / Create the hub vnet with all its components module hubvnet './modules/hub-default.bicep' = { name: 'hub-vnet' scope: resourceGroup(hubrg.name) params: { location: location hubVnetName: hubvnetName hubFwName: 'hub-fw' tags: tags } } there is a folder called ‘modules’ that contains the smaller parts of the whole implementation such as: The hub virtual network with all its components like the Azure Firewall and Azure Bastion The Virtual Network for the AKS cluster The Virtual Network for the Development Virtual Machines (agents) The VNET peering and route tables The private AKS cluster The AKS’s private DNS zone links to hub and dev Virtual Networks The dev VM which is an Ubuntu with Docker extension Running the script First you have to install the Bicep executable by following this guide: Setup your Bicep development environment Then, you will need to install either the Az CLI (2.20.0+) or the PowerShell Az module (v5.6.0+) that have Bicep support built-in. After that, you will need to run the following commands in an Azure CLI or PowerShell console: // Login to your Azure account az login // clone the repository git https://github.com/vakappas/private-aks-bicep.git // Start the deployment az deployment sub create -f ./private-aks.bicep -l northeurope As you see, you can use the standard deployment commands with your *.bicep files and the tooling will transpile the code and send it to ARM on your behalf.
  2. The greatest, community driven, technical event in Greece for IT Professionals and Developers is back! It’s been long time since the last ITPRO|DEV Connections event took place. There are a few reasons for that, but this does not matter anymore as we proudly bring it back to life and this time in virtual form! This event is community driven, and this year the number of the communities that take part are bigger than ever before. This signifies great momentum and deep commitment from the community members to help and support other community members. More than 100 speakers with real-world experiences and different backgrounds, leaving in different parts of the world, as now we have grown outside Greek borders, are getting together and sharing their knowledge with all the members of 15 technical communities that are embracing the ITPRO|DEV Connections 2020! The event’s tracks It will be 2 full days with parallel tracks running from ~10am to ~6pm (local time, that is GMT+2) and it will cover the following categories (in alphabetical order): AI & ML Data & Analytics Development DevOps Infrastructure Learning & Certification Modern Workspace Networks & Security Project Management All sessions are 45 minute long. The event is FREE, but you have to register here: The event’s details We have created the event on a platform that will have all the amenities of a normal conference, like sponsor booths, networking groups for 1-to-1 messaging and video calls, session evaluations, and of course a way to build your own personal schedule for your favorite sessions! The event comes with a very handy mobile app that you get to build your schedule and give session feedback and more. So make sure that you download the app and configure it with the 4-digit code that corresponds to our event. All this information is in the registration confirmation email! Also, this year is going to be delivered in 2 languages, so make sure you check the session tags for the tag “Lang: EL” or “Lang: EN” in a blue-ish color. Since we are in the tags area, there are mainly 4 different colors for tags: Dark blue: Session track Magenta: Session tags Light green: Session level Light blue: Session language I’m speaking! Apart from being in the organizing team, I have also a session, where I will talk about how the cloud is changing the way infrastructure is designed, and how you can build a highly available and scalable security perimeter by using Cisco Firepower Threat Defense virtual appliances. The session is called “Cisco NGFWv scalable design in Azure” and is on Saturday, 12th at 1 pm (GMT+2). The session is demo heavy as it is inspired by real customer project! Looking forward to welcome you if it happens to drop by. Call for action! What are you waiting for? Register here https://www.itprodevconnections.gr build your agenda and join us on 12-13 of December. Don’t forget to use the official hashtag of the event in any of your posts which is #itprodevgreece
  3. As you already know Exchange Server 2016 will be entering Extended Supporton October 14th 2020.. During that period it will receive only Critical and will be no further release of CUs, with the last planned CU to be released in December 2020. One of the many concerns regarding that transition is that at the moment there is no free Exchange Server 2019 license for just managing the exchange attributes on hybrid deployments as there is for Exchange 2016. According to the Product Group that specific license for the Exchange Server 2019 will be release after 14th October. Also as a heads-up the product group is working on a solution that will remove the need of those on-premise “management attributes| only servers. Microsoft encourages Exchange Server 2016 customers to adopt CU19 as soon as possible to ensure uninterrupted delivery of any future security related fixes. After December 15, 2020, only CU19 or its successors will receive critical updates. During the Extended Support phase, only the latest CU is eligible to receive critical updates once the standard 3 month transition period of the prior CU has lapsed. Critical updates will continue to be made available via Windows Update and the Microsoft Download Center. Additional lifecycle information for all Microsoft products is available on docs.microsoft.com. These are great news since is the first time that a working plan for the retirement of those on-premise server serving only for management is announced.

  5. This cumulative update is a security update. It includes fixes for nonsecurity issues and all previously released fixes for security and nonsecurity issues Cumulative Update 6 for Microsoft Exchange Server 2019 was released on June 16, 2020. This cumulative update is a security update. It includes fixes for nonsecurity issues and all previously released fixes for security and nonsecurity issues. These fixes will also be included in later cumulative updates for Exchange Server 2019. This update also includes new daylight saving time (DST) updates for Exchange Server 2019. For more information about DST, see Daylight Saving Time Help and Support Center. Known issues in this cumulative update In multidomain Active Directory forests in which Exchange is installed or has been prepared previously by using the /PrepareDomain option in Setup, this action must be completed after the /PrepareAD command for this cumulative update has been completed and the changes are replicated to all domains. Setup will try to run the /PrepareAD command during the first server installation. Installation will finish only if the user who initiated Setup has the appropriate permissions. Notes If you are upgrading from Cumulative Update 2 for Exchange Server 2019 or a later cumulative update for Exchange Server 2019 to Cumulative Update 6 for Exchange Server 2019, there’s no need to run the /PrepareAD or /PrepareDomain. No additional actions (prepareAD, prepareDomain, or assigning permissions) are required. If you have ever skipped a Cumulative Update (for example, you are upgrading from an earlier version before Cumulative Update 2 for Exchange Server 2019), or this is a first Exchange Server installation in the AD, then this Known Issue section should be taken care of. About the /PrepareDomain operation in multidomain: The /PrepareDomain operation automatically runs in the Active Directory domain in which the /PrepareAD commandis run. However, it may be unable to update other domains in the forest. Therefore, a domain administrator should run the /PrepareDomain in other domains in the forest. About the permission question: As the /PrepareAD is triggered in Setup, if the user who initiates Setup isn’t a member of Schema Admins and Enterprise Admins, the readiness check will fail and you receive the following error messages. To avoid the errors, either the user should join Schema Admins and Enterprise Admins groups or another user in Schema Admins and Enterprise Admins groups manually runs the /PrepareAD for this Cumulative Update first. Then, the Exchange admin user can start Setup. Autodiscover Event ID 1 occurs after you install Cumulative Update 3 for Exchange Server 2019. For more information, see KB 4532190. Issues that this cumulative update fixes This cumulative update also fixes the issues that are described in the following Microsoft Knowledge Base articles: 4559441 Foreign language characters set in RejectMessageReasonText of a transport rule aren’t shown correctly in Exchange Server 2019 4547707 Enable piping for Restore-RecoverableItems in Exchange Server 2019 4549689 HMA EvoSTS certificate rollover causes authentication prompts due to stalled key on worker process spawn (warmup phase) in Exchange Server 2019 4559446 Changes to Outlook on the web blocked file extensions and MIME types in Exchange Server 2019 4559440 Export to a PST for an eDiscovery search fails Exchange Server 2019 4559439 EAS creates failure report if a message with unknown recipients is in Drafts in Exchange Server 2019 4559442 2080 Events caused by empty values in HKLM\SYSTEM\CurrentControlSet\Services\MSExchange ADAccess\Instance0 in Exchange Server 2019 4559438 Edge Transport server hangs in Exchange Server 2019 4559443 Managed Folder Assistant fails with Event ID 9004 NotInBagPropertyErrorException in Exchange Server 2019 4559437 PR_RECIPIENT_ENTRYID is computed if no email address or type in Exchange Server 2019 4559444 Conversion from HTML to RTF removes non-breaking space in Exchange Server 2019 4559436 Attachments with properties (like Azure Information Protection labels) not always matching in Exchange Server 2019 4559435 Introduce an OrganizationConfig flag to enable or disable recipient read session in Exchange Server 2019

If you have ever skipped a Cumulative Update (for example, you are upgrading from an earlier version before Cumulative Update 2 for Exchange Server 2019), or this is a first Exchange Server installation in the AD, then this Known Issue section should be taken care of. About the /PrepareDomain operation in multidomain: The /PrepareDomain operation automatically runs in the Active Directory domain in which the /PrepareAD commandis run. However, it may be unable to update other domains in the forest. Therefore, a domain administrator should run the /PrepareDomain in other domains in the forest. About the permission question: As the /PrepareAD is triggered in Setup, if the user who initiates Setup isn’t a member of Schema Admins and Enterprise Admins, the readiness check will fail and you receive the following error messages. To avoid the errors, either the user should join Schema Admins and Enterprise Admins groups or another user in Schema Admins and Enterprise Admins groups manually runs the /PrepareAD for this Cumulative Update first. Then, the Exchange admin user can start Setup. Autodiscover Event ID 1 occurs after you install Cumulative Update 3 for Exchange Server 2019. For more information, see KB 4532190.

  18. This cumulative update is a security update. It includes fixes for nonsecurity issues and all previously released fixes for security and nonsecurity issues. Known issues in this cumulative update In multidomain Active Directory forests in which Exchange is installed or has been prepared previously by using the /PrepareDomain option in Setup, this action must be completed after the /PrepareAD command for this cumulative update has been completed and the changes are replicated to all domains. Setup will try to run the /PrepareAD command during the first server installation. Installation will finish only if the user who initiated Setup has the appropriate permissions. Notes:If you are upgrading from Cumulative Update 2 for Exchange Server 2019 to Cumulative Update 3 for Exchange Server 2019, then there’s no need to run the /PrepareAD or /PrepareDomain. No additional actions (prepareAD, prepareDomain, or assigning permissions) are required.If you has ever skipped a Cumulative Update (for example, you are upgrading from an earlier version before Cumulative Update 2 for Exchange Server 2019), or this is a first Exchange Server installation in the AD, then this Known Issue section should be taken care of. a. About the /PrepareDomain operation in multidomain: The /PrepareDomain operation automatically runs in the Active Directory domain in which the /PrepareAD commandis run. However, it may be unable to update other domains in the forest. Therefore, a domain administrator should run the /PrepareDomain in other domains in the forest. b. About the permission question: As the /PrepareAD is triggered in Setup, if the user who initiates Setup isn’t a member of Schema Admins and Enterprise Admins, the readiness check will fail and you receive the following error messages: To avoid the error messages, either the user should join Schema Admins and Enterprise Admins groups, or another user in Schema Admins and Enterprise Admins groups manually runs the /PrepareAD for this Cumulative Update first. Then the Exchange admin user can start Setup.The Set-SendConnector cmdlet does not work for Exchange Server 2019 in hybrid scenarios that have a Edge server installed.

  23. What is Nano Server ? Nano Server is a new installation option that became available with the arrival of Windows Server 2016 Technical Preview. It is a purpose-built, stripped down operating system designed to run services and to be managed remotely. Windows Server 2016 will offer the following installation options: http://vaggeliskappas.com/wp-content/uploads/2015/11/NanoServer01-1024x638.png Nano Server has been designed according to Zero-Footprint model and its size on disk is around 500MB. It has no GUI, binaries or metadata in the OS image, it sets up significantly faster and requires far fewer updates and restarts than Windows Server. As an installation option cannot be selected during Windows Server Setup and in order to prepare and customize a VHD image with Nano Server, PowerShell should be used. Nano Server can run either as a Virtual or Physical Machine supporting the following Roles and Features: Role / Feature Physical / Virtual Description Compute Physical Hyper-V Role Storage Both Storage role Clustering Both Failover Clustering role Reverse Forwarders Both Helps in testing legacy tools Defender Both Anti-Malware Defender package OEM drivers Physical Selection of drivers that ship in-box with Server Core Guest drivers Virtual Drivers needed to run Nano Server as a VM In order to deploy Nano Server as a Virtual Machine into a Hyper-V host running Windows Server 2016, the following procedure could be used: Step 1 – Mount the ISO Mount the Windows Server 2016 Technical Preview ISO and copy the contents of \NanoServer folder. If the drive letter for the mounted image is G:\ run the following commands: md C:\NanoServer xcopy G:\NanoServer C:\NanoServer /s Step 2 – Dot-Source the Scripts The PowerShell Scripts that are included into the Installation folder need to be dot-sourced, in order to be used for the Nano Server VHD creation. Alternatively, it is possible to use another PowerShell Script that you will find at TechNet Library or GitHub, for that matter. cd C:\NanoServer . .\Convert-WindowsImage.ps1 . .\New-NanoServerImage.ps1 Step 3 – Create a VHD Run the following command to prepare a Nano Server VHD: New-NanoServerImage -MediaPath G:\ -BasePath .\Base ` -TargetPath .\NSVM01 -ComputerName NSVM01 ` –GuestDrivers –language en-us -Storage -Clustering ` -EnableIPDisplayOnBoot -DomainName "MGMT.local" ` -EnableRemoteManagementPort New-NanoServerImage CmdLet allows us to specify Media and Target Path, set the Computer Name, add right set of drivers for Physical or Virtual Machine, select if the Nano Server will join an Active Directory Domain etc. Most important, it allows us to select which Roles or Features are going to be installed. Please note that if you are running New-NanoServerImage.ps1 on a non-English installation of Windows you should include –language en-us. If you don’t include this, the script will default to your local language–because there are currently no localized builds of Windows Server 2016 it will fail to find the appropriate packages. Step 4 – Create a Virtual Machine As soon as the New-NanoServerImage.ps1 has been successfully completed, a new VHD with Nano Server will be available and can be attached as a boot device to a Generation 1 Virtual Machine. VM creation can be done with the following script: $VMName = "NSVM01" $VMPath = "F:\Hyper-V\"+$VMName $VirtualSwitchName = "vSwitch-INT" New-VM -Name $VMName -MemoryStartupBytes 1GB -SwitchName $VirtualSwitchName ` -VHDPath "$($VMPath)\NSVM01.vhd" -Generation 1 ` | Set-VM -ProcessorCount 2 Start-VM $VMName A couple of seconds after hitting the Start-VM Command, Nano Server will boot and the following screen will appear: http://vaggeliskappas.com/wp-content/uploads/2015/11/NanoServer02-1024x950.png Next, Login using Domain credentials and the Emergency Management Console will appear: http://vaggeliskappas.com/wp-content/uploads/2015/11/NanoServer03-1024x953.pngNavigate using TAB, choose Networking and get Network Adapter’s Settings as shown below: http://vaggeliskappas.com/wp-content/uploads/2015/11/NanoServer04-1024x950.pngHow-to Manage the Nano Server Nano Server has no GUI or any other console, except of Emergency Management Console that right now is very restricted and can be used only to display Network Adapter’s Properties. So, how can we manage Nano Server? Can be managed Remotely using the following tools: Remote Graphical Tools (Server Manager, Hyper-V Manager, Disk Manager etc.) PowerShell Remoting PowerShell Direct Third Party Tools & Frameworks (Chef, ASP.NET 5 etc.) Enter a PowerShell remote Session, using the following command: Enter-PSSession -ComputerName NSVM01 -Credential MGMT\administrator Then run Get-Process Cmdlet and get the processes that are running to the Nano Server http://vaggeliskappas.com/wp-content/uploads/2015/11/NanoServer05-1024x699.png Resources More information about Nano Server and its deployment Scripts you can find at the following URLs: http://aka.ms/NanoServer PowerShell Script to build your Nano Server Image The post Getting Started with Nano Server appeared first on Vaggelis Kappas.
  24. Lately, I have been under the rock of work and that is why i didn’t write about this sooner. On October 1st I received an email saying: http://vaggeliskappas.com/wp-content/uploads/2015/10/MVP2015.png As you can imagine i was eagerly awaiting for this email and the excitement i got was really great. I would like to thank all community members of autoexec.gr and friends, many of whom are or were fellow MVPs, for their help, support and guidance throughout this last year. Last but not least, I would like to thank my friends working at Microsoft Hellas for continuously supporting the community and for the confidence they showed me, ‘’pushing’’ me forward. I look forward to continuing my contribution to IT Pros community with the same passion for the years to come. The post 2015 Microsoft MVP Award on Hyper-V appeared first on Vaggelis Kappas.
