Microsoft Azure PowerShell Runbooks for Auto-Scale Configuration

In this blog post, we will explore how to configure auto-scale using Azure PowerShell runbooks with the Azure VMware solution. This feature was requested by the Azure VMware Solution Product Group to provide a cost-effective way for customers and partners to meet performance goals with the Azure VMware Solution.

The Azure VMware solution is a hybrid cloud offering that allows organizations to extend their on-premises data centers to the Microsoft Azure cloud. It provides a seamless experience between the two environments, allowing organizations to run their applications and workloads in a consistent manner across both platforms.

One of the key benefits of the Azure VMware solution is its ability to support mission-critical workloads with high availability and scalability. Auto-scale is a feature that enables organizations to automatically adjust the number of instances running in their applications based on demand. This can help organizations optimize resource utilization, reduce costs, and improve application performance.

To configure auto-scale using Azure PowerShell runbooks with the Azure VMware solution, we need to follow these steps:

Step 1: Create an Azure Resource Manager (ARM) template for the Auto-Scale configuration. This template will define the resources required for the Auto-Scale configuration, such as the virtual machines, networks, and storage accounts.

Step 2: Use Azure PowerShell runbooks to deploy the ARM template and configure the auto-scale settings. The runbook will need to retrieve the ARM template from a designated location and then use the Azure Resource Manager API to deploy the resources defined in the template. Once the resources are deployed, the runbook can configure the auto-scale settings using the Azure Monitor API.

Step 3: Define the Auto-Scale configuration in the ARM template. This will include defining the minimum and maximum number of instances that should be running, as well as the cool-down period between scaling events.

Step 4: Test the auto-scale configuration to ensure it is working correctly. This can be done using Azure Monitor, which provides a comprehensive view of application performance and resource utilization.

Benefits of Using Azure PowerShell Runbooks for Auto-Scale Configuration

There are several benefits to using Azure PowerShell runbooks for auto-scale configuration with the Azure VMware solution:

1. Cost savings: By automatically adjusting the number of instances running based on demand, organizations can reduce their costs by only running the number of instances required to meet performance goals.

2. Improved application performance: Auto-scale can help improve application performance by ensuring that there are always enough instances running to handle incoming traffic. This can lead to faster response times and a better user experience.

3. Increased agility: With auto-scale, organizations can quickly respond to changes in demand or other business requirements. They can also easily experiment with different scaling configurations to find the optimal balance between performance and cost.

4. Simplified management: Azure PowerShell runbooks provide a simple and intuitive way to configure and manage auto-scale settings. This can help reduce the administrative burden on IT staff, allowing them to focus on other critical tasks.

VMware Cloud on AWS: A Promising Future for Legacy Applications

As a seasoned IT professional, I recently had the opportunity to delve into the latest book from Packt, titled “VMware Cloud on AWS Blueprint: Design, automate, and migrate VMware workloads on AWS global infrastructure.” The book provides a comprehensive overview of VMware Cloud on AWS, its features, and best practices for migrating and scaling legacy applications on this platform.

One of the most significant strengths of this book is its ability to demystify the concept of VMware Cloud on AWS and provide a clear understanding of its capabilities. The author does an excellent job of explaining the benefits of this platform, such as its ability to seamlessly migrate and scale legacy applications, while also providing a solid foundation for future growth and development.

The book is structured into three main areas: design, automation, and migration. Each section provides valuable insights and practical examples for leveraging VMware Cloud on AWS to achieve specific business outcomes. However, I noticed that the design portion of the book is somewhat distributed throughout the different chapters, with the exception of Chapter 11, which provides specific best practices and the appendix, which covers preparation before adopting VMware Cloud on AWS. A dedicated part or even a separate book focused solely on design would be beneficial for readers looking to gain a deeper understanding of this aspect.

Chapter 8, while informative, feels somewhat disconnected from the rest of the content. The chapter primarily focuses on explaining various AWS services but does not provide adequate guidance on how or when to refactor or adapt workloads to use them effectively. A more comprehensive approach to this topic would be valuable for readers looking to maximize the potential of VMware Cloud on AWS.

On the other hand, Chapter 9 is a standout section that covers automation in detail. While it could benefit from additional examples, the chapter provides a solid foundation for readers looking to automate their workloads on VMware Cloud on AWS. Chapter 10 is also noteworthy, as it dedicates an entire chapter to AWS Outpost, which is often overlooked or underappreciated. Providing a dedicated chapter for this topic is a good idea and demonstrates the book’s commitment to covering all aspects of VMware Cloud on AWS.

In conclusion, “VMware Cloud on AWS Blueprint” is an excellent resource for anyone looking to understand the capabilities and potential of VMware Cloud on AWS. While it could benefit from more examples and use cases in certain areas, the book provides a solid foundation for readers looking to leverage this platform for their legacy applications. With VMware’s continued push towards this service and its growing adoption, this book is sure to become an essential resource for anyone looking to stay ahead of the curve in the world of virtualization and cloud computing.

In addition to the book’s content, I would like to mention that VMware has announced a preview of the VMware Hybrid Cloud Extension service as an add-on service to VMware Cloud on AWS. This new offering will enable customers to adopt the latest VMware Cloud on AWS offers without the need for a full migration. This development highlights VMware’s commitment to continuously improving and expanding its offerings on this platform, further solidifying its potential for businesses of all sizes and industries.

Microsoft Provides Multiple Solutions for Migrating Off of VMware

In recent months, there have been significant changes at VMware since the acquisition by Broadcom. As a result, many customers are looking for alternatives to VMware and considering migrating off of their platform. Fortunately, Microsoft offers several solutions that can help businesses transition away from VMware and provide different benefits and use cases depending on customer needs.

Azure VMware Solution

The Azure VMware Solution is a viable option for companies looking to exit an existing data center while ensuring minimal disruption during the migration process. This solution allows customers to continue using familiar VMware tools and processes, ensuring operational continuity. Additionally, it provides the ability to take advantage of Azure’s scalability and resiliency, as well as other Azure integrations.

With the Azure VMware Solution, customers can continue to use their existing VMware investments, such as vSphere, vSAN, and vCenter, without needing to re-architect applications or convert VMs. Microsoft fully manages this solution, freeing businesses from maintaining physical servers and VMware infrastructure, allowing them to focus on their workloads.

Native Azure VM Migration

For organizations looking to completely exit VMware, they can migrate VMware VMs natively to Azure VMs. This migration path eliminates VMware licensing costs and provides native integration with Azure services. Customers will often see a more cost-effective and scalable cloud solution with this option.

To migrate to Azure VMs, customers need to convert VMware VMs into Azure’s native format using the Azure Migrate tool. The tool simplifies the migration process, including discovery, assessment, and migration, and it is agentless, so there is no need to first deploy agents to VMs.

Azure Stack HCI

Microsoft’s hybrid cloud solution, Azure Stack HCI, is purpose-built for running HCI environments. However, it is fully tied into Microsoft Azure and offers all the Azure benefits and integrations for environments using Azure Stack HCI. This option is ideal for businesses that want to maintain some of their workloads on-premises while still benefiting from cloud capabilities.

System Center

For organizations that prefer a traditional, on-premises solution, migrating VMware workloads to Windows Server managed with System Center offers a proven and familiar option. This approach provides full control over the infrastructure but also introduces many more complexities with management. However, it is an option for businesses that do not want to use cloud services.

Hyper-V Server 2019

Of course, it’s still possible to run Windows HyperV Server 2019 for free. It supports all features, including clustering, but you must license any individual Windows VMs. It will happily run Linux. It can be managed from Windows Admin Centre for free too. This is a good option for those who want to use it to run Hyper-V in their home lab or freely with Linux workloads.

In conclusion, Microsoft provides multiple solutions for migrating off of VMware, each offering different benefits and use cases depending on customer needs. These options include Azure VMware Solution, Native Azure VM Migration, Azure Stack HCI, System Center, and Hyper-V Server 2019. Therefore, customers can choose the solution that best fits their needs and provides a seamless transition away from VMware.

As a seasoned IT professional, I have been working with VMware vCenter for quite some time now. Recently, one of our customers requested us to change the swap location to a different datastore, as the current datastore was about to be removed in the near future. However, what we encountered was a small HTML5 UI-bug in vCenter 7.0 Update 2 that prevented us from selecting a datastore. In this blog post, I will share the workarounds we used to overcome this issue and apply the change via PowerShell/PowerCLI.

The Issue: Swap File Location Not Selectable

—————————————–

When we tried to change the swap file location in vCenter 7.0 U2, we noticed that the whole mask was simply disabled, as shown below:


This was quite frustrating, as it prevented us from selecting a different datastore for the swap location. However, after some research, we found that this issue is already addressed and will be fixed in vCenter 7.0 U3.

Workaround: Apply Change via PowerShell/PowerCLI

———————————————

Since the issue is only present in the HTML5 UI client, we can use PowerShell/PowerCLI to apply the change on all hosts in a specific cluster or on a specific host. Here are the steps to apply the change via PowerShell/PowerCLI:

### Apply Change on All Hosts in a Specific Cluster

To apply the change on all hosts in a specific cluster, follow these steps:

1. Open PowerCLI and connect to your vCenter server.

2. Run the following command to set the swap file location to a different datastore:

“`powershell

Set-VMHost -Name -SwapFileLocation Datastore:

“`

Replace `` with the name of the host you want to apply the change to, and `` with the name of the datastore you want to use for the swap location.

### Apply Change on a Specific Host

To apply the change on a specific host, follow these steps:

1. Open PowerCLI and connect to your vCenter server.

2. Run the following command to set the swap file location to a different datastore:

“`powershell

Get-VMHost -Name | Set-VMHost -SwapFileLocation Datastore:

“`

Replace `` with the name of the host you want to apply the change to, and `` with the name of the datastore you want to use for the swap location.

Conclusion

———-

In this blog post, we discussed a small HTML5 UI-bug in vCenter 7.0 U2 that prevents the user from selecting a datastore for the swap location. However, we also provided two workarounds to overcome this issue and apply the change via PowerShell/PowerCLI. These workarounds can be used on all hosts in a specific cluster or on a specific host. We hope this helps you in your day-to-day tasks and saves you some time and effort.

Virtualization, Storage, and various other ramblings: Leveraging the Nvidia GPU operator in a K3s cluster

In this article, we will explore how to leverage the Nvidia GPU operator in a K3s cluster, using a cheap Nvidia T400 GPU that is on the supported list for the operator. We will go over the necessary steps to install and configure the GPU operator, as well as some tips and tricks to keep in mind when working with this technology.

First, we will need to create a new VM in vSphere with PCI Passthrough enabled, so that we can present the Nvidia GPU to the VM. We will then need to install the Nvidia GPU operator chart within K3s, and configure the Containerd runtime to use the GPU.

To begin, we will create a new VM in vSphere with PCI Passthrough enabled. This will allow us to present the Nvidia GPU to the VM, so that we can use it for computing tasks. Once the VM is created, we will need to install the Nvidia GPU operator chart within K3s.

To install the Nvidia GPU operator chart, we will first need to import an existing cluster in Rancher. This will allow us to manage our K3s cluster and deploy the GPU operator chart. Once the cluster is imported, we can navigate to the Cluster -> Apps -> Charts page, and search for the “GPU” chart. We can then select the chart and click the “Install” button to install it within our K3s cluster.

Once the GPU operator chart is installed, we will need to configure the Containerd runtime to use the GPU. This can be done by adding the following configuration to the Containerd config file:

“`

[runtime]

class = nvidia.com/gpu-operator

“`

This will tell Containerd to use the Nvidia GPU operator when running containerized workloads. We can then restart the Containerd service to apply the changes:

“`

sudo systemctl restart containerd

“`

At this point, we should be able to run containerized workloads on our Nvidia GPU. However, there are a few things to keep in mind when working with the GPU operator.

First, you will notice that there are two devices represented by the Nvidia GPU – one for the video controller, and another for the audio controller. We only need the video controller, so we should ignore the audio controller device.

Second, you may encounter issues with the GPU driver not being installed correctly. To resolve this, you can try installing the Nvidia driver manually before installing the GPU operator chart. This will ensure that the driver is properly installed and configured.

Finally, you may notice that the GPU operator Pods are in a crashloop state initially. This is expected until the nvidia-driver-daemonset Pod has finished building and installing the Nvidia drivers. You can follow the Pod logs to get more insight into what’s occurring.

In conclusion, leveraging the Nvidia GPU operator in a K3s cluster can be a powerful way to improve the performance of containerized workloads. By following these steps and keeping a few tips and tricks in mind, you should be able to successfully install and configure the GPU operator within your K3s cluster.

My primary focus is to design and deploy network virtualization, NSX advanced load balancer (AVI), and SDDC solutions for VMware customers.

In my previous blog post, I discussed the importance of network virtualization and how it can revolutionize the way we approach networking in the modern data center. In this post, I would like to dive deeper into the concept of NSX advanced load balancer (AVI) and how it can help organizations achieve their business goals.

NSX Advanced Load Balancer (AVI) is a key component of the VMware NSX platform that enables organizations to build more agile, flexible, and scalable data center networks. AVI provides a centralized management platform for load balancing, application delivery controllers (ADC), and SSL/TLS termination. This allows organizations to efficiently distribute traffic across their infrastructure, improve application performance, and enhance security.

One of the biggest benefits of NSX Advanced Load Balancer (AVI) is its ability to provide a unified management platform for all load balancing and application delivery needs. This means that organizations can easily manage and monitor their applications from a single console, which can help reduce operational complexity and improve efficiency.

Another key advantage of AVI is its support for advanced load balancing algorithms, such as IP Hash, Least Connection, and Ratio. These algorithms allow organizations to distribute traffic across their infrastructure in a more intelligent and efficient manner, which can help improve application performance and availability.

In addition to these benefits, NSX Advanced Load Balancer (AVI) also provides a number of security features that can help organizations protect their applications and data from external threats. For example, AVI supports SSL/TLS termination, which allows organizations to encrypt traffic between the client and server, and prevent eavesdropping and man-in-the-middle attacks.

One of the most exciting aspects of NSX Advanced Load Balancer (AVI) is its ability to integrate with other VMware solutions, such as vSphere and vRealize Automation. This allows organizations to create a seamless and integrated infrastructure that can be managed from a single console.

For example, organizations can use vRealize Automation to automate the deployment of AVI, which can help reduce the time and effort required to deploy and manage load balancing solutions. Additionally, AVI can be integrated with vSphere to provide advanced load balancing and application delivery capabilities for virtualized workloads.

In conclusion, NSX Advanced Load Balancer (AVI) is a powerful solution that can help organizations build more agile, flexible, and scalable data center networks. With its centralized management platform, advanced load balancing algorithms, and security features, AVI is an essential tool for any organization looking to improve application performance and availability.

As a Senior Consultant/Architect within the VMware Professional Services Organisation – NSX Practice, I have had the privilege of working with numerous organizations to deploy and implement NSX Advanced Load Balancer (AVI) solutions. I have seen firsthand the benefits that AVI can bring to an organization, and I am excited to see how this technology will continue to evolve in the future.

Welcome back to our ongoing blog series on NSX 4.0! In the previous parts of this series, we have covered the installation of NSX Manager, adding a compute manager, and configuring the NSX VIP. Today, we will be discussing how to migrate workloads from vCenter VDS to NSX environments.

Before we begin, please note that this blog post is intended for educational purposes only, and it is not recommended to perform these actions in a production environment without proper testing and planning. Additionally, some of the commands and screenshots may vary based on the version of NSX and vCenter you are using.

Migrating Workloads from VDS to NSX Environments

————————————————–

In this section, we will demonstrate how to migrate workloads from vCenter VDS to NSX environments. We will be using three Windows VMs as test VMs and connecting them to different port groups on vCenter VDS. We will then move these VMs from VDS to NSX managed segments.

Step 1: Create Segments in NSX Environments

——————————————–

Before we can migrate the workloads, we need to create segments in NSX environments. A segment is nothing but a portgroup. Let’s have a look at the types of segments:

* VLAN Baked Segments: In this type, you will define a VLAN ID for the segments, however, you also have to make sure that this vlan configure exists on your physical top of the rack switch.

* Overlay Backed Segments: This segment can be configured without any configuration on the physical infrastructure. It gets attached to overlay transport zone and traffic is carried by a tunnel between the hosts.

For this demo, we will only focus on VLAN backed segments. If you are looking for overlay backed segments, please refer to my previous blog post.

Step 2: Add Licenses to NSX Environments

—————————————–

Before we can create segments, we need to add licenses to our NSX environments. To do this, log in to the NSX VIP and navigate to System > Licenses. Here, you can add your license key.

Step 3: Create VLAN Backed Segments in NSX Environments

——————————————————

Now that we have added licenses, let’s create VLAN backed segments in NSX environments. To do this, log in to the NSX VIP and navigate to Networking > Segments. Here, you can create a new segment for each of your networks that exist on your TOR (top of the rack switches).

For this demo, we will be using Management-1631, vMotion-1632, and VSAN-1633 networks. In my lab environment, these networks are pre-created on the TOR.

To create a VLAN backed segment, click on the “Add Segment” button and provide the following information:

* Name: The name of the segment.

* Transport Zone: The virtual transport zone to which the segment will be attached.

* VLAN: The VLAN ID that you want to use for this segment.

Once you have provided all the necessary information, click “OK” to create the segment.

Step 4: Migrate Workloads from VDS to NSX Environments

—————————————————

Now that we have created segments in our NSX environments, let’s migrate our workloads from vCenter VDS to these segments. To do this, log in to the vCenter server and navigate to the VMs that you want to migrate. Right-click on each VM and select “Edit VM settings.”

In the “VM Settings” window, select the “Networking” tab and select the segment that you created earlier. You can also select the “Multiple Networking” option if you want to assign multiple segments to a single VM.

Once you have selected the desired segment for each VM, click “OK” to save the changes. This will move the workloads from VDS to NSX environments.

Conclusion

———-

In this blog post, we have demonstrated how to migrate workloads from vCenter VDS to NSX environments. We have also covered the creation of segments in NSX environments and adding licenses to NSX environments. These are just some of the basic steps that you can follow to migrate your workloads from VDS to NSX environments.

In our next blog post, we will be discussing some of the use cases for VLAN backed segments. We will also be exploring why customers would only configure VLAN backed segments and not overlay or T1, T0, and Edge. So, stay tuned and keep an eye on my blog for more information on NSX 4.0!

vSAN Scrubber: Ensuring Data Integrity and Reduced Downtime in vSAN Environments

In a vSAN environment, data integrity is of utmost importance. With the increasing use of stretched clusters and site-affinity set to either preferred or secondary sites, it’s crucial to ensure that data is accurately persisted across disks and mirrors. One of the key components of vSAN’s background operations is the scrubber, which detects and fixes checksum and IO errors to maintain data integrity. In this blog post, we’ll delve into the inner workings of the vSAN scrubber, its new advancements in vSAN 7.0U1c, and how it can help reduce downtime in vSAN environments.

What is vSAN Scrubber?

The vSAN scrubber is a background operation that runs on the domain owner (DO) and detects/fixes checksum and IO errors in vSAN objects. It performs two primary functions:

1. Detection (scrub): The scrubber identifies and reports any checksum or IO errors found in vSAN objects, ensuring that these errors are addressed before they cause any issues.

2. Fixing (recover): If the scrubber detects errors, it performs recovery operations to fix them, ensuring that the data remains accurate and intact.

Why is vSAN Scrubber Important?

The vSAN scrubber is crucial in maintaining data integrity and reducing downtime in vSAN environments. Here are some reasons why:

1. Medium errors: vSAN stores data on physical capacity disks, which can be prone to medium errors due to hardware failures or other issues. The scrubber detects these errors and fixes them before they cause any problems.

2. Cross-site traffic: In stretched clusters, site affinity is set to either preferred or secondary sites to avoid cross-site traffic. However, this can lead to a situation where reads are performed only on a single mirror, causing checksum errors to go undetected until a resync task is triggered.

3. Maintenance tasks and hardware failures: Maintenance tasks and hardware failures can result in resync tasks, which may discover and report checksum errors or I/O failures due to bad sectors backing the object’s component.

Advancements in vSAN 7.0U1c Scrubber

In vSAN 7.0U1c, the advanced scrubber value “VSAN.ObjectScrubsPerYear” has been increased from 1 per year to 6 per year for each object. This means that the scrubber will now scrub every object once every two months, ensuring that all affected components with unreadable blocks, incorrect checksums are relocated to different sectors/disks by rebuilding from neighboring components/mirrors.

Additionally, vSAN 7.0U1c includes new statistics against certain VMDKs, allowing you to monitor checksum errors and ETA for scrubber completion. This information can be useful in troubleshooting issues and identifying potential problems before they become major incidents.

Benefits of Enhanced Scrubber in vSAN 7.0U1c

The enhanced scrubber in vSAN 7.0U1c offers several benefits to maintain data integrity and reduce downtime in vSAN environments, including:

1. Improved detection and fixing of checksum and IO errors: The increased frequency of scrubs ensures that errors are detected and fixed more promptly, reducing the likelihood of data corruption and downtime.

2. Reduced downtime: By detecting and fixing errors more quickly, the scrubber helps reduce downtime and maintain business continuity.

3. Better monitoring: New statistics against certain VMDKs provide better monitoring capabilities, allowing you to identify potential issues before they become major incidents.

Conclusion

In conclusion, the vSAN scrubber is a critical component of vSAN’s background operations that ensures data integrity and reduces downtime in vSAN environments. With the advancements in vSAN 7.0U1c, the scrubber now scrubs every object once every two months, providing improved detection and fixing of checksum and IO errors, reduced downtime, and better monitoring capabilities. By understanding how the scrubber works and its new advancements, you can ensure that your vSAN environment remains stable, reliable, and high-performing.

As of today, I am proud to call myself an officially recognized VMUG Leader for the Belgian community. This is a huge responsibility, and I am excited to work together with Maarten Van Driessen and Jens Herremans to make sure that we fill in the void left behind by the former VMUG Leader, Erik Schils.

I am thrilled to take on this leadership role for many reasons. Firstly, it will push me out of my comfort zone, which is always a good thing. I am used to speaking with customers and peers, but being in front of an auditorium and speaking to hundreds of people is still daunting. However, I am excited to learn and grow from this experience.

Another reason I am eager to take on this role is the challenge of creating an event that is educational for a variety of different people. I want to make sure that everyone can learn something new and valuable from our events. Whether it’s learning about a specific technology or networking with fellow professionals, I want to ensure that our events provide value to all attendees.

Furthermore, this leadership role will allow me to expand my own network. I will have the opportunity to interact with a wide range of people during the event, including partners and sponsors. Additionally, I will be able to network with VMUG leaders from all over the world and learn from their experiences on how to create successful events.

Finally, I am excited to make our event grow bigger than ever before and potentially even surpass VMUG NL. This is an ambitious goal, but I believe that we can achieve it with hard work, dedication, and a focus on providing value to our attendees.

Officially launched in August 2010, the VMware User Group (VMUG) is an independent, global, customer-led organization that aims to maximize members’ use of VMware and partner solutions through knowledge sharing, training, collaboration, and events. In Belgium, this is an annual VMUG event that has been hosted in Mechelen since its inception. The event provides a space for partners, vendors, and customers to meet, network, and attend sessions hosted by industry and community experts.

In addition to the annual VMUG event, we also have the concept of “vBeers,” which is a community-based initiative that focuses on connecting like-minded people who have a passion for technology and virtualization. These events are held monthly (every 3rd Thursday of the month) with one or two short sessions. The sessions can be technology-related, but they don’t have to be. The goal of vBeers is to provide a low-entry platform for inexperienced public speakers to gain experience and test their public speaking skills between similar vGeeks.

We want to fuse the VMUG and vBeers concepts into one event, creating an event like VMUG with the atmosphere and energy of a vBeers. We want to return to the basics of VMUG and provide practical value to our attendees. As leaders, we are just a small portion of how we see the VMUG concept grow in Belgium. We need YOUR input on how we can bring VMUG to the next level.

To gather your feedback and ideas, we have created a short survey that will only take a few minutes of your time. This survey will provide essential information on what we can do to make VMUG the perfect format for you. Please click here to access the survey: [insert link to survey].

We are currently working hard on getting things rolling and hope to host a physical/virtual VMUG later this year in June! We’re also planning to do an online pre-VMUG session, which will be a 2-hour event with lots of community speakers presenting smaller sessions. And here, we will also announce our VMUG event.

For the vBeers, we host these every 3rd Thursday of each month. We’re also thinking about organizing bigger vBeers twice or three times per year, where we would invite a partner to dive deeper into a specific area. Stay tuned and looking forward to seeing you on our next vBeers or VMUG!
