What I like about this concept is the idea that you could have hypervisor tiers of service, where perhaps your highest priority VMs are on vSphere and lower priority VMs are in Hyper-V. It’s all managed from vCenter, and VMs can easily be moved back and forth.

According to Lynn, by having these hypervisor tiers, Hotlink says that you can buy Hotlink SuperVISOR and still save your company a lot of money. This is because you can use the lower-cost Hyper-V or Xen hypervisors for non-critical workloads, while still using vSphere for your most important VMs. This approach could help organizations reduce their overall virtualization costs, while still maintaining a high level of performance and reliability.

I was also impressed with the product demo that Hotlink provided. They showed how easy it is to administer both your internal vSphere infrastructure and your Amazon public IaaS cloud using their Hybrid Express solution. The demo included showing how to move VMs back and forth between the two environments, as well as how to manage storage and networking across both environments.

One thing that caught my attention was the use of PowerCLI on Amazon EC2 at the end of the video. This is a very cool feature that allows you to automate tasks and manage your AWS environment using the same PowerCLI scripts that you use in your vSphere environment. This could be a game-changer for organizations that use both AWS and vSphere, as it allows them to leverage the power of PowerCLI across both environments.

In conclusion, Hotlink is a company that offers some innovative solutions for multi-hypervisor management and hybrid cloud management. Their Hybrid Express solution and Hotlink SuperVISOR tool offer a seamless experience for administrators who need to manage both their on-premises infrastructure and their Amazon public IaaS cloud. Additionally, the use of PowerCLI on Amazon EC2 is a very cool feature that could be a game-changer for organizations that use both AWS and vSphere. If you’re looking for a solution that can help you manage your virtualization infrastructure more efficiently and cost-effectively, Hotlink is definitely worth considering.

3. Migrate the workload: After preparing the source vCenter, you can start the migration process. There are two methods to migrate workloads between different vCenters – quick migration and advanced migration. Quick migration is recommended for small workloads, while advanced migration is recommended for larger workloads or for workloads with complex dependencies.

4. Verify the migration: After completing the migration process, you need to verify that the workload has been successfully migrated to the destination vCenter. This includes verifying that the virtual machines are powered on and accessible from the destination vCenter.

Benefits of Cross-vCenter Migration

Cross-vCenter migration offers several benefits, including:

1. Flexibility: With cross-vCenter migration, you can move your workloads between different vCenters as needed, providing more flexibility in managing your VMware environment.
