Overview

Enterprises usually start the large-scale migration to the cloud after a pilot project is successful. The large-scale cloud migration can be completed in two ways:

• Batch migration: This approach is best for divisible workloads. Enterprises typically divide the migration process into multiple batches, and complete them one by one. The following figure shows the process of batch migration.

• Integrated migration: This approach applies to systems where applications are associated with each other in a complex manner and cannot be migrated in batches. The following figure shows the integrated migration process.
