Lift and Shift to the Cloud Made Easier: Migrating Workloads to GCP with Migrate for Compute Engine
So, you’re thinking about moving your on-premises workloads to Google Cloud Platform (GCP)? Smart move! The cloud offers tons of advantages: scalability, cost optimization, improved security, and access to cutting-edge technologies. But the migration process can seem daunting, especially if you have a lot of virtual machines (VMs) running critical applications.
That’s where Migrate for Compute Engine (formerly Velostrata) comes in. Think of it as your reliable moving van, helping you transport your on-premises VMs to GCP with minimal disruption.
This blog post will walk you through the basics of Migrate for Compute Engine, making it easy to understand for both beginners and intermediate users. We’ll cover what it is, why you’d use it, and the general process.
What is Migrate for Compute Engine?
Migrate for Compute Engine is a service that allows you to migrate your virtual machines from on-premises environments (like VMware vSphere, Microsoft Hyper-V, or even other cloud platforms) to Google Compute Engine (GCE). It’s designed to minimize downtime and make the migration process as seamless as possible.
Instead of manually copying huge VM images, Migrate for Compute Engine uses a clever technique called streaming. Your VMs aren’t completely moved upfront. Instead, they’re streamed to GCP as needed, allowing you to run them in the cloud while the background migration completes.
Why Choose Migrate for Compute Engine?
Here’s why Migrate for Compute Engine is a great option for moving your workloads to GCP:
- Minimal Downtime: This is the big one! You can start your VMs in GCP almost immediately after initiating the migration. The application stays up and running while the data is being copied in the background. This is a huge advantage over traditional migration methods that can require significant downtime.
- Reduced Risk: By testing workloads in the cloud before fully migrating, you can validate your application’s performance and compatibility in the GCP environment. This helps you identify and address any potential issues before making the final cutover.
- Faster Migration: Streaming eliminates the need to copy large VM images upfront, significantly reducing the time it takes to get your applications up and running in the cloud.
- Cost Optimization: You only pay for the resources you use in GCP. You can even leverage preemptible instances for non-critical workloads during the migration process to save money.
- Non-Disruptive Testing: Test your migrated workloads in GCP without impacting your on-premises environment. This gives you confidence in the migration process.
- Automated Process: Migrate for Compute Engine automates many aspects of the migration process, reducing manual effort and the potential for errors.
How Does Migrate for Compute Engine Work?
Here’s a simplified overview of the migration process:
- Install the Migrate for Compute Engine Backend: This component is installed in your on-premises environment. It acts as the gateway between your VMs and GCP. It handles tasks like preparing the VMs for migration and initiating the data streaming. This component depends on your on-prem virtualization platform (vSphere, Hyper-V etc).
- Install the Migrate for Compute Engine Plugin/Extension: Depending on your virtualization platform, this is installed within your vCenter or Hyper-V manager. This allows you to manage and orchestrate the migration process directly from your familiar environment.
- Configure Connection to GCP: You’ll need to configure a connection between your on-premises environment and your GCP project. This typically involves setting up a service account with the necessary permissions.
- Select VMs for Migration: Choose the VMs you want to migrate.
- Create a Wave (Optional, but recommended): Group your VMs into logical waves to manage the migration process in a structured manner. This is especially helpful for complex applications with dependencies.
- Test (Run in Cloud): Launch the VMs in GCP in “Run in Cloud” mode. This allows you to test the application in the cloud environment without cutting over the entire workload. The system streams the necessary data to GCP as the application runs.
- Migrate (Cutover): Once you’re satisfied with the testing, perform the final cutover. This completes the data migration and finalizes the VM in GCP.
Key Components to Know:
- Migrate for Compute Engine Backend (formerly Velostrata Backend): Installed on-premises, handles data streaming and communication with GCP.
- Migrate for Compute Engine Plugin/Extension: Integrates with your virtualization platform management console (e.g., vCenter) to manage the migration process.
- Cloud Extension: A Compute Engine instance in your GCP project that serves as the target for migrated VMs.
- Wave: A logical grouping of VMs that are migrated together.
Getting Started:
The best way to understand Migrate for Compute Engine is to try it out! Here are some resources to help you get started:
