What are the 4 phases of cloud migration?

Successful cloud migration requires a structured approach.

The process is typically divided into four key phases:

• Phase 1: Prepare
  This phase will set the foundation for any successful migration. It involves the assessment of the existing IT environment, which includes the identification of applications and data that will be migrated and the evaluation of cloud providers. Drive down a robust business case along with the necessary stakeholder buy-in.
• Phase 2: Plan
  Design an elaborate migration strategy with detailed timelines, resources, and risks. Architect the cloud environment in line with business needs and define tools for migration and methodologies.
• Phase 3: Migrate
  Run the migration plan to move applications and data into the cloud environment. At this phase, there is data migration, application testing, and cutover planning.
• Phase 4: Operate and Optimize
  Once in the cloud, optimize performance, cost, and security. Monitor and manage as a continuous process. Always be looking to review and further update your cloud strategy to ensure maximum benefits.

The phases above help an organization take the journey of cloud migration effectively and achieve the desired business outcomes. Knowing the difference between cloud migration and cloud application modernization is critical from the view of decision-making.
