Change management and validation as the cornerstone

We are working under architecture from this point onward. This implies that the changes that are made to the systems in our environment are controlled from the architecture. Sometimes, these changes have an impact on the architecture itself, where we will need to change the architecture. In multi-cloud environments, that will actually happen a lot.

Cloud platforms are flexible in terms of use and thus our architecture can't be set in stone: it needs to allow improvements to be made to the environments that we have designed, thereby enabling that these improvements are documented and embedded in the architecture. Improvements can be a result of fixing a problem or mitigating an issue to enhancements. Either way, we have to make sure that changes that are the result of these improvements can be validated, tracked, and traced. Change management is therefore crucial in maintaining the architecture.

Since we have already learned...
