Cloud Native Architectures

Core tenets

Cloud-native applications must be scalable and available. In order to achieve this bar, resilient systems in the cloud must make use of the concepts introduced in this chapter. We've summarized the core tenets that one should abide by to build cloud-native applications as follows:

• Compute is distributed and the application is stateless:
  • Distribute across multiple zones and geographies. Take full advantage of the scale of hyper-cloud providers and build your own systems to be multi-zonal or multi-regional.
  • A stateful application keeps data about each session on the machine and uses that data while the session is active. A stateless application, however, does not keep any session state data on the server/host. Instead, the session ...
