I’m more DevOps but we have issues wear we discuss the spherical cow of build pipelines like we have a handful of static environments in the same cloud account with the same permissions and database requirements that does not stand up to encountering the actual requirements where we have destructible and static environments, an environment in a different cloud account for our customer to review per contract requirements, and a prod environment with heavy security and data protection requirements hosted by a entirely different cloud vendor with bad infrastructure support resources.
