What Are Cloud Migration Strategies?

A cloud migration strategy is when a business plans its migration from on-premises servers to a cloud-based server. Businesses will also implement strategies when they transfer from one cloud provider to another. Regardless, the aim is to complete the transition and also identify/address possible roadblocks. 

When implementing a cloud migration strategy, companies should look at their digital assets. They don’t need to move all of them, but it does involve migrating at least some. Things like IT resources and applications are often part of a cloud migration strategy. 

Businesses must migrate to a cloud system for scalability and modernization, though some have a mix of on-premises and SaaS.
