Windows Server 2019 now available in preview

March 21, 2018 Leave a comment


On March 20th 2018, Microsoft announced that Windows Server 2019, which is built on the strong foundation of Windows Server 2016, are now released to Preview. You can get access to the preview build through Microsoft Insiders program.

Windows 2019 will be generally available (GA) in the second half of calendar year 2018.


Some tips:

  • The Windows Server vNext Semi-Annual Preview – Build 17623 is Server Core ONLY



  • If you downloaded the VHDX version, as the file is compressed, make you sure you remove the compress check in the properties of the file as per below image as it will fail to start the VM if you don’t:


  • Capture3


  • Download the Windows Server vNext LTSC Preview – Build 17623, if you are looking for the Full GUI version.


Use the following keys provided by Microsoft (

Windows Server 2019 Build 17623  is available in ISO format in 18 languages. This build and all future pre-release builds will require use of activation keys during setup. The following keys allow for unlimited activations:

Datacenter Edition


Standard Edition



So, what features to look for in the new in Server 2019:


·        Cluster Sets, the new cloud scale-out technology, is a loosely-coupled grouping of multiple Failover Clusters: compute, storage or hyper-converged. Cluster Sets technology will enable virtual machine fluidity across member clusters within a Cluster Set and a unified storage namespace across the “set” in support of virtual machine fluidity.  

·        Failover Cluster without NTLM authentication, which allows failover clusters to be deployed in environments where NTLM has been disabled.

·        Shielded VM’s Offline mode, Alternate HGS and Shielded Linux support, which allows you to run HyperV shielded virtual machines on hosts that suffer intermittent connectivity to their Host Guardian Service (HGS).  The fallback HGS will allow you to configure a second set of URLs for Hyper-V to try if it can’t reach the primary HGS server.

·        Shielded VM’s Alternate HGS, which allows you to run HyperV shielded virtual machines on hosts that suffer intermittent connectivity to their Host Guardian Service (HGS).  The fallback HGS will allow you to configure a second set of URLs for Hyper-V to try if it can’t reach the primary HGS server. 

·        Shielded VM’s Offline mode, which takes the high availability promise for shielded VMs one step further and allows you to continue to start up a shielded VM even if the host’s primary and fallback HGSs can’t be reached.

·        Shielded VM’s Shielded Linux support, for customers that run mixed-OS environments, Microsoft now supports Ubuntu, Red Hat Enterprise Linux, and SUSE Linux Enterprise Server Shielded virtual machines.

·        Encrypted Network in SDN, which provides simple to configure DTLS-based encryption using the Network Controller to manage the end-to-end encryption and protect data as it travels through the wires and network devices between the hosts., enabling the VM to VM traffic within the VM subnet to be automatically encrypted as it leaves the host and prevents snooping and manipulation of traffic on the wire.  This is done without requiring any configuration changes in the VMs themselves.

· Performance history for Storage Spaces Direct, which allow Administrators of Storage Spaces Direct get easy access to historical performance and capacity data from their cluster.

·        Windows Defender Advanced Threat Protection, ,which provides deep platform sensors and response actions, providing visibility to memory and kernel level attacker activities and abilities to take actions on compromised machines in response to incidents such as remote collection of additional forensic data, remediating malicious files, terminating malicious processes etc.

·        Windows Defender ATP Exploit Guard ,which is new set of host intrusion prevention capabilities, designed to lock down the device against a wide variety of attack vectors and block behaviours commonly used in malware attacks:

Modernize your workload with #AKS #Kubernets #Containers #MicroServices

March 16, 2018 Leave a comment

When comes to Application Modernisation, we can’t argue that Containers are leading the way.  With Containers you can wrap up an application into its own isolated box meaning that app will have no knowledge of any other applications or processes that exist outside of its box.

With Containers, you can wrap up a monolithic application or create a more modern approach: a microservice-based architecture, in which the application is built on a collection of services that can be developed, tested, deployed, and versioned independently, which is perfect for mission-critical application scenarios.

Monolithic deployment versus the microservices approach. Image Source: Microsoft Docs (

If you own the app source code and are on a optimisation path, I would recommend the microservices approach, which allows agile changes and rapid iteration allowing you to change specific areas of complex, large, and scalable applications. But if do not have the source code or breaking the application code in to small pieces it is not feasible, you still can look at Containers as away to modernize the app. Either way, you also need to consider: Automation, Management, High-Availability, Networking, Scalability, Upgrades and Monitoring requirements.

Automating and Managing Containers:

The task of automating and managing a large number of containers and how they interact is known as orchestration. Azure offers two container orchestrators: Azure Container Service (AKS) and Service Fabric.

Azure Container Service (AKS) makes it simple to create, configure, and manage a cluster of virtual machines that are preconfigured to run containerized applications. This enables you to maintaining application portability through Kubernetes and the Docker image format.

Azure Service Fabric is a distributed systems platform that makes it easy to package, deploy, and manage scalable and reliable microservices and containers. Service Fabric addresses the significant challenges in developing and managing cloud native applications.  Service Fabric reresents the next-generation platform for building and managing these enterprise-class, tier-1, cloud-scale applications running in containers.

Wondering how you could use Microsoft OMS to have a single view of the jobs’ status across multiple VMM instances?

Well, you can now deploy an open-source solution that can be included in your OMS workspace called Virtual Machine Manager Analytics . This solution brings in the job data of your on-premises VMM instances to the log analytics in OMS. VMM admins can then use this versatile platform to construct queries for searching the relevant data and creating data visualizations.

The Virtual Machine Manager Analytics solution comes with some built-in reports with preconfigured data visualizations so you can easily get started with frequently used queries, such as:

  • Distribution of failed jobs across VMM instances to easily scope down the broken instances.
  • Distribution of failures over time to find sudden spikes, and to help with correlating the cause and failures.
  • Distribution of failed jobs and errors to help with identifying the most error-prone jobs and the cause.
  • Distribution of the job runtime across different runs to identify the sluggish and error-prone jobs.

Additionally, the VMM jobs data in OMS Log Analytics can be correlated with the data from other OMS solutions for better debugging and auto resolution with Azure automation Runbooks

VMM 2016 1801 release. Configuration of guest clusters in SDN through VMM has undergone some changes.

February 19, 2018 1 comment



With the release of the update 1801 for System Center VMM 2016, configuration of guest clusters in SDN through VMM has undergone some changes.

With network controller in place, now VMs that are connected to the virtual network using SDN are only allowed to use the IP address that the network controller assigns for communication. Inspired by Azure networking design, VMM enables this feature by emulating the floating IP functionality through the Software Load Balancer (SLB) in the SDN.


IMPORTANT: Network Controller does not support floating IP addresses which are essential for technologies such as Microsoft Failover Clustering to work.


VMM supports guest clustering in SDN through an Internal Load Balancer(ILB) Virtual IP(VIP).  Guesting clustering is managed through the SDN NC. Before you start, ensure you have set up SDN and deployed NC and SLB

The ILB uses probe ports which are created on the guest cluster VMs to identify the active node. At any given time, the probe port of only the active node responds to the ILB and all the traffic directed to the VIP is routed to the active node

Key features of the new Microsoft Azure Site Recovery Deployment Planner

December 19, 2017 2 comments

Azure Site Recovery Deployment Planner is now GA with support for both Hyper-V and VMware.

Disaster Recovery cost to Azure is now added in the report. It gives compute, storage, network and Azure Site Recovery license cost per VM.

ASR Deployment Planner does a deep, ASR-specific assessment of your on-premises environment. It provides recommendations that are required by Azure Site Recovery for successful DR operations such as replication, failover, and DR-Drill of your VMware or Hyper-V virtual machines.  

Also, if you intend to migrate your on-premises workloads to Azure, use Azure Migrate for migration planning. Azure Migrate assesses on-premises workloads and provides guidance

 Key features of the tool are:

  1. Estimated Network bandwidth required for initial replication(IR) and delta replication.
  2. Storage type(standard or premium storage) requirement for each VM.
  3. Total number of standard and premium storage accounts to be provisioned.
  4. For VMware, it provides the required number of Configuration Server and Process Server to be deployed on on-prem.
  5. For Hyper-V, it provides additional storage requirements on on-premises.
  6. For Hyper-V, the number of VMs that can be protected in parallel (in a batch) and protection order of each batch for successful initial replication.
  7. For VMware, the number of VMs that can be protected in parallel to complete initial replication in a given time.
  8. Throughput that ASR can get from on-premises to Azure. 
  9. VM eligibility assessment based on number of disks, size of the disk  and IOPS, OS type.   
  10. Estimate DR cost for the target Azure  region in the specific currency.

When to use ASR Deployment Planner and Azure Migrate?

  • DR from VMware/Hyper-V to Azure
  • Migration from VMware to Azure
