Looking at Azure’s approach to IaaS
When you are migrating legacy applications to Azure, IaaS is often considered the first step. This is usually because migrating the existing workloads involves the least amount of risk, but not always. Whether you are rehosting or refactoring, IaaS can offer some benefits when it comes to the first step in your modernization journey.
For some organizations that are modernizing application workloads, the steps of the journey look like this:
- Rehost or refactor to Azure VMs.
- Modernize to cloud-native services where it makes sense.
This is often a good approach for modernization because it allows you to leverage the other benefits of Azure, such as its analytics platform, and also lets you say goodbye to your expensive legacy hardware.
