Cloud migration entails transferring an organization's data, applications, and IT resources from on-premises infrastructure to a cloud platform. This process allows businesses to leverage the benefits of cloud computing, such as enhanced scalability, flexibility, and cost-effectiveness. Cloud migration can involve several strategies, including rehosting, which moves applications as-is, and refactoring, which involves modifying applications to optimize them for the cloud environment. Successful migration strategies can lead to improved performance, security, and access to advanced technologies.
