In order to take rebuild approach We should have access to proper documentation of selected application or it needs to be already part of CI/CD process. In case there is an existing CI/CD pipeline, We analyze it and advise, which components might be moved to AWS SAAS services to get the maximum benefit from AWS Managed Services. We show costs, risks and profits of such shift in components.
If application doesn’t use DevOPS model and doesn’t have any of CI/CD pipeline – We try to rebuild it based on documentation available. We give access to test environment under which We work with customer to validate if the rebuild approach was successful. After positive validation we agree on timeline, possible downtime of application and do the actual re-build in AWS. After doing cur-over we support application rebuild and advice over further possible enhancements.
