Instead of implementing isolation at the cluster level, Kardinal implements isolation by deploying development versions of services side-by-side with their "staging" versions, and creating isolated traffic routes through the cluster. -These traffic routes connect development versions to their appropriate dependencies, and to development versions of any databases, queues, caches, and external APIs that you may need. They are effectively "logical environments" or "views" on top of a single cluster. In Kardinal, these are called "flows". Flows enable isolation for the purpose of development, testing, and QA with the lowest possible resource footprint. +These traffic routes connect development versions to their appropriate dependencies, and to development versions of any databases, queues, caches, and external APIs that you may need.
