Application Platform - Services
This is the configuration diagram of the application platform of the open cloud platform K-PaaS.
Shows the service and service broker API architecture.

Service

1.어플리케이션 플랫폼:Cloud Controller에서 set VCAP_SERVICES를 통해 App A(App environment VCAP_SERVICES:-inst0 : url, credentials에 연결 후 binding하여 Service의 service back-end(service Instance 0)에 연결 2.어플리케이션 플랫폼:Cloud Controller에서 set VCAP_SERVICES를 통해 App B(App environment VCAP_SERVICES : -inst0 : url, credentials, inst-0 : url,credentials)에 연결 후 binding하여 Service의 service back-end(service Instance 0과 service Instance 1)에 연결 3.어플리케이션 플랫폼:Cloud Controller에서 Service broker API(catalog, Provision, Updateprovision, Bind, Unbind, Deprovision)로 연결 그 다음 Service(Service broker)로 연결 후 service back-end(service Instance 0과 service Instance 1)에 연결

Functions and roles of the components

K-PaaS service API defines the protocols (catalog, provision, unprovision, updateprovision, bind, unbind) between Cloud Controller and the service broker.
The broker is implemented as a RESTful API in the form of an HTTP (or HTTPS) endpoints URI. One or more services can be provided by a single broker, and can scale horizontally with load balancing.
Also, service instances in multiple execution environments can be supported by a single broker using different URL prefixes and credentials.
The service is used in the execution environment by implementing the cloud controller client API called the service broker API.
The service API is an independent version of the cloud controllerAPI.
This makes external applications available on the platform (database, message queue, rest endpoint, etc).

Service Broker API Architecture

1.목록 중 cf create-service-broker를 router로 2.Cloud Controller로 보낸 후 3.Service API(Fetch catalog(GET/v2/catalog))로 4.MySQL Broker(previously Gateway)와 상호작용, 1.목록 중 cf marketplace는 router없음, 1.목록 중 cf create-service는 2.Cloud Controller로 보낸 후 3.Service API(Provision Instance(PUT/v2/service Instance/:id))로, 1.목록 중 cf update-service는 2.Cloud Controller로 보낸 후 3.Service API(Update Provision Plan(PATCH/v2/service Instance/:id))로, 1.목록 중 cf unbind-service는 2.Cloud Controller로 보낸 후 3.Service API(Create Binding(PUT/v2/service Instance/:instance id/service_bindings/:id))로, 1.목록 중 cf unbind-service는 2.Cloud Controller로 보낸 후 3.Service API(Remove Binding(DELETE/v2/service Instance/:instance id/service_bindings/:id))로, 1.목록 중 cf delete service는 2.Cloud Controller로 보낸 후 3.Service API(Remove Instance(DELETE/v2/service Instance/:id))로 4.MySQL Broker(previously Gateway)와 상호작용
