Cloud migration is the process of moving applications, data, infrastructure, security, and other objects to a cloud computing environment.Much like a move from a smaller office to a larger one, cloud migration requires quite a lot of preparation and advance work, but usually it ends up being worth the effort, resulting in cost savings and greater flexibility.
Most often, "cloud migration" describes the move from on-premise or legacy infrastructure to the cloud. However, the term can also apply to a migration from one cloud to another cloud.
- Scalability: Cloud computing can scale up to support larger workloads and greater numbers of users far more easily than on-premise infrastructure, which requires companies to purchase and set up additional physical servers, networking equipment, or software licenses.
- Cost: Companies that move to the cloud often vastly reduce the amount they spend on IT operations, since the cloud providers handle maintenance and upgrades. Instead of keeping things up and running, companies can focus more resources on their biggest business needs – developing new products or improving existing ones.
- Performance: For some businesses, moving to the cloud can enable them to improve performance and the overall user experience for their customers. If their application or website is hosted in cloud data centers instead of in various on-premise servers, then data will not have to travel as far to reach the users, reducing latency.
- Flexibility: Users, whether they are employees or customers, can access the cloud services and data they need from anywhere. This makes it easier for a business to expand into new territories, offer their services to international audiences, and let their employees work flexibly.
