Four steps for a successful cloud migration
Cloud migration is a fundamental part of a company’s digital transformation, it is important to have a structured plan in order to implement it correctly. In the following blog, we would like to present the four steps needed for successful cloud migration.
Understand the resources involved in the process
Identify which applications are in our servers and what databases we have. This step is vital in order to avoid the overlapping and incomplete applications that will slow down the migration process.
Also, there are some applications that can migrate without much effort, almost without a code modification; other applications which must be completely reprogrammed because they are using outdated technologies, and also applications that can’t be migrated such as the legacy systems.
Select the right cloud provider
Before deciding on which provider to select, there are some points to define about the cloud architecture; what type of data processing, space and security is required; and whether the cloud needs to be private, public or hybrid.
The provider must be multi-cloud: in order to manage more than one kind of cloud, they need to pinpoint the desirable architecture and the types of components that need to be used.
Define a migration plan
Define a migration plan and analyze if it is necessary to migrate all the applications together or to migrate in stages. It is recommendable to start with the independent applications, with new initiatives and/or products that do not interfere with the daily operations.
The strategy depends on each company’s priorities and maturity. At this stage, it is important to minimize the inactivity time and also to avoid disrupting the most critical applications which are in use. Furthermore, we need to create a back-up of the whole information and also implement stress tests
Implement a constant supervision
A weekly check on the use of the applications is necessary, and then a monthly one, in order to achieve the optimization of the resources.
Also, it is necessary to check the new functionalities that are incorporated into the cloud in order to improve their architecture and efficiency.
