Leverage a fully managed API gateway to create a barrier at the boundaries of a cloud-native system by pushing cross-cutting concerns, such as security and caching, to the edge of the cloud where some load is absorbed before entering the interior of the system.
Cloud-native systems are composed of bounded isolated components, which are responsive, resilient, elastic, and message-driven. All inter-component communication is performed asynchronously via event streaming. Components publish events to downstream components and consume events from upstream components. We strive to limit synchronous communication to only the intra-component cloud-native databases and to the cloud-native streaming service. Yet, sooner or later, we have to implement synchronous communication at the boundaries of the system. At the boundaries, the system interacts with users via mobile apps and single page web applications and with external systems via Open APIs.
