What is cloud migration?

Cloud migration refers to the process of moving digital assets, such as applications, data, IT resources, or workloads, from on-premises infrastructure or legacy systems to a cloud computing environment. This transition enables organizations to leverage the scalability, flexibility, cost-efficiency, and advanced features of cloud platforms.

There are several types of cloud migration strategies:

1. Rehosting (Lift-and-Shift): Moving applications as-is to the cloud without significant changes. For example, migrating a company’s on-premises database server to a virtual machine in the cloud.
2. Refactoring (Re-architecting): Modifying applications to optimize them for cloud-native features, such as microservices or containerization.
3. Rebuilding: Completely rebuilding applications using cloud-native technologies and services.

Example: A retail company might migrate its e-commerce platform from an on-premises data center to a cloud environment to handle peak traffic during sales events. By using auto-scaling and load balancing, the platform can dynamically adjust resources based on demand, improving performance and reducing costs.

For businesses considering cloud migration, Tencent Cloud offers comprehensive solutions, including Cloud Migration Services to simplify the process, Elastic Compute Service (CVM) for scalable computing power, and Object Storage (COS) for secure data storage. These services help ensure a smooth transition while optimizing costs and performance.
