A comprehensive strategy that defines the project’s success, establishes migration targets, defines a timeframe, compensates for challenges, and is planned for and implemented in advance is crucial to successful cloud migration.
The workload and new features that are planned to be added after migration are important factors to consider while migrating to the cloud. By defining use cases in advance, organizations may develop a sound plan that provides the groundwork for a complete migration process.
Risk analyses, budgeting, security, and the cloud type, public or private, that will host each of the migrated workloads are included in migration strategies. Determining whether to encrypt all or specific categories of data, adhering to rules governing data in motion and at rest, and replication needs are all components of a cloud migration security plan.
The communication component of the migration plan also identifies the roles and responsibilities of each stakeholder in the project. Common cloud migration strategies are:
Re-factor (lift, tinker, and shift): Organization updates the application’s components to meet functional, security, and enterprise standards.
–Re-platform; Migrate to an operating system version based on CNaaS platform standards, introducing scaling or automation, thus reducing operational expense.
–Re-host (lift & shift); shifting an application from an on-premises host to a cloud service (infrastructure or platform service).
–Repurchase; Entails abandoning outdated systems in favor of online services. Enterprises opt to repurchase when an organization’s legacy system is incompatible with the intended cloud environment, and business requirements call for a change.
–Retain; Retain some digital assets rather than retire them for technical, security, compliance, or economic purposes.
