Cloud migration refers to moving all digital resources from on-premise or another cloud to the cloud. The first step to migration is to create a solid cloud migration strategy. Cloud migration strategies are essential for existing cloud users and companies that want to move their legacy systems to the cloud.
These are some cloud migration strategies:
- Hosting
It is also known as the “lift and shift” strategy. This involves moving a copy of existing infrastructure to the cloud. This is a good option for small organizations with simple workloads and still working out long-term plans regarding services and scalability. This approach is ideal for companies whose infrastructure heavily relies on virtual machines.
- Replatforming
This strategy is also known as the ‘move-and-improve’ strategy. It requires minimal changes to prepare for the cloud transition and includes provisions to make scaling easier. The core application architecture is unaffected. This is just a minor variation of the rehosting strategies.
- Repurchasing
Sometimes parts of legacy architecture can become expensive and difficult to maintain and may prove impossible to scale up. For example, an in-house CRM system. This capability can be transferred to a cloud-based solution such as Salesforce’s cloud CRM.
- Refactoring
Refactoring is a way to rebuild the entire infrastructure. This is the best way for organizations to take advantage of all the benefits cloud computing offers, including serverless computing and auto-scaling. These features are not possible with an on-premise setup.
- Retire
Many infrastructure components in large enterprises are obsolete or no longer necessary once they move to the cloud. These modules can be costly and a security risk. It is sensible to dispose of these modules and not move them to the cloud.
- Maintaining
Sometimes, the market cloud platforms may have different modules than the ones in the infrastructure. This can lead to data not being transferable due to compliance issues or architecture built recently with additional capital. These cases are where it makes economic and operational sense to keep these modules on-premise.
Cloud migration strategies require careful planning, testing, resourcing, and resource allocation. Now, you might be searching for “managed IT services near me.”
