Environment

Environment is a collection of infrastructures, covering computing, storage, and networks, used for application deployment and running. ServiceStage combines basic resources, such as Cloud Container Engine (CCE) and Elastic Cloud Server (ECS) and optional resources, such as Elastic Load Balance (ELB) and Distributed Cache Service (DCS) in the same VPC into an environment, such as the development environment, testing environment, pre-production environment, and production environment. Networks in an environment can communicate with each other. You can manage resources and deploy services by environment, simplifying infrastructure O&M.

Infrastructure

In ServiceStage, infrastructure refers to the basic services that are required or optional to microservice application hosting and O&M, such as Cloud Container Engine (CCE).

Application

An application is a service system with functions and consists of one or more application components.

Application Component

An application component implements a service feature of an application. It is in the form of code or software packages and can be deployed independently.

ServiceComb

Apache ServiceComb is an open-source microservice project. It is compatible with popular ecosystems and provides a one-stop open-source microservice solution, featuring out-of-the-box readiness, high performance, and multi-language programming. It aims to help enterprises, customers, and developers easily deploy enterprise applications on the cloud in the form of microservices and implement efficient O&M.

Microservice

Microservice is defined by service. If a process provides a service, it is a microservice. Each service has its own service functions. APIs that are not restricted by languages are open to other systems (HTTP frequently used). Multiple microservices form an application.

NOTE:

In ServiceStage, a microservice is relative to an application component.

Microservice instance

An instance is the minimum running and deployment unit of a microservice. Generally, it corresponds to an application process.
