Hypermedia allows traversing entire REST API description of microservicesĬloud FoundryTo always be shipping, you need a shipyard. HATEOASHypermedia as the Engine of Application State (REST APIs that self-describe)ĪPI gateway downloads routes from services exposing REST APIsĮach route of other microservices will be hosted on the API gatewayĪPI gateway will automatically reverse proxy to backend services What is Spring Cloud? Spring Cloud provides a way to turn Spring Boot microservices into distributed These logos are all trademark/copyright their respective owners (T-B, L-R): Netflix,, Apache Software Foundation, Cloud Foundry, Hashicorp they are ALL great organizations and we love their open-source and their APIs!! Spring CloudA toolset designed for building distributed systems Supports rapid development of production-ready applications and servicesĪutomatic Configuration An application class is annotated with annotations are added to indicate the role of the Spring Boot application Spring Initializr for boostraping your applications Spring BootA JVM micro-framework for building microservices Service discovery provides an automatic method for finding other service dependencies Orchestration Each microservice needs to communicate outside containers Minutes to start a VM, but seconds to start a containerĪn elastic runtime handles auto-scaling of VMs with cloud providers Microservices - Container Deployment Each microservice can be containerized with their application dependenciesĬontainers get scheduled on virtual machines with an allotted resource policy Its not a rule that there is one microservice per container Linux Container Deployment - Microserviceĭevelopment team drives the application runtime of a containerĬontainers are resource isolated, allowing efficient scheduling onto a grid of VMsĬontainers take seconds to start, VMs take minutes Runtime environment is driven by the operator Poor resource isolation memory leaks can cause other applications to become unavailable Load balancing requires provisioning of new VMs and app server installations Microservices are only a small part of a larger picture Shared caches are platform provided services that are shared for consistency Microservice Architecture Each team gets one database and one service
