AWS Cloud Map
#130 · Level 4 · Operations and specialized areas · Advanced networking and hybridConcept
Section titled “Concept”AWS Cloud Map is service discovery — an up-to-date list of which part of your app is running at which address right now. Services live inside a namespace, and the running copies of each service are called instances. When another part of the app asks for a name through DNS or the API, Cloud Map gives back the addresses of the healthy instances. With health checks, unhealthy instances are dropped from the list. Services such as Amazon ECS can write container addresses into Cloud Map on their own.
