What does migration in cloud computing refer to?

Migration in cloud computing specifically refers to the process of moving data, applications, and workloads from on-premises environments to the cloud or between cloud environments. This involves various stages, including planning, transferring data, deploying applications, and ensuring that workloads function correctly in the new environment. Migration is critical for organizations looking to take advantage of cloud scalability, flexibility, and cost efficiency.

The process can encompass several methods, including rehosting (lift and shift), refactoring, rearchitecting, and rebuilding, depending on the organization's specific needs and goals. Successful migration helps organizations modernize their infrastructure, improve performance, and facilitate better collaboration and agility.

Other options focus on different aspects of cloud computing. The expansion of cloud services is more about market reach than the specific process of migration itself. Creating new cloud-native applications relates to development practices rather than the movement of existing systems to the cloud. Reducing resource usage touches on efficiency but does not capture the essence of what migration entails.
