Aspects of Cloud Migration
Aspects of Cloud Migration
Deciding to use the cloud is one thing — actually moving there is another. This section covers the directions a migration can run, the phases it moves through, how virtualization migrations differ from cloud migrations, and the eight strategies for handling any given application.
Migration Types
When you think of cloud migration, you probably envision moving data, services, applications, and other portions of the IT infrastructure to the cloud. There are three kinds of cloud migrations. Click each to see how it flows.
Phases of Cloud Migration
The four phases of the cloud migration process are assess, plan, implement, and optimize the deployment. Every phase is approached with the business's strategic and tactical goals in mind — risk mitigation, scalability, increased availability.
Your organization will probably accomplish its cloud deployment across several distinct sub-phases, which generally include:
Virtualization Migrations
It's important to differentiate between cloud migrations and virtualization migrations — physical servers might be migrated to a locally hosted, non-cloud data center virtualization host. There are three types of virtualization migrations, each following an assess → plan → deploy → optimize flow.
A small sample of the migration tools CSPs provide — many third-party solutions exist as well.
Application Migration Strategies
Eight cloud migration types describe how a given application is handled, ranging from no modification at all to a full rebuild — or no move at all. Drag along the spectrum, from least to most modification required.
