Cloud migration involves the process of moving data, applications, and workloads from on-premises infrastructure to cloud-based environments. This transition can occur in various forms, including lift-and-shift (rehosting without changes) or through a more complex re-architecture process. Organizations typically migrate to enhance scalability, reduce costs, and improve accessibility and flexibility. However, successful cloud migration requires careful planning, consideration of compliance regulations, and the implementation of security measures to protect data throughout the transition process.
