Cloud Migration

Cloud migration is the process of moving an organization's digital assets, such as data, applications, and IT workloads, from on-premises infrastructure to a cloud computing environment, or from one cloud provider to another. This strategic initiative is undertaken to leverage the benefits of the cloud, including enhanced scalability, cost-effectiveness, performance, and operational agility. The process requires careful planning and execution, involving a spectrum of strategies that range from a simple "lift-and-shift" of existing systems to a more complex re-architecting of applications to be fully cloud-native.
