Micro-service architecture is a solution

Evolution of Enterprise Application Architecture: single-machine program->c/s->b/s, service-oriented architecture (SOA), micro-service architecture

Bold is the monomer program

Micro-Service Architecture

A fine-grained SOA is an SOA that emphasizes small, ephemeral components, and small is the beauty

The focus is on services, how to decouple between services

Each service component can be independently developed, built, tested, deployed

Self-contained (as in a container)

Lightweight process

Developing with RESTful Web services

Communicate over HTTP (must I communicate through HTTP?). ）

Related to Team organization structure

Basic mode: (API Gateway +n a single service structure)

Soa

Exposing Simple Object-based Access Protocol (SOAP)

Middleware, such as Enterprise Service Bus (ESB), is important

Service-based development (presentation tier, service tier (may be divided by business service with many block service APIs), database)

Monomer Service

Classic N-tier structure (presentation layer, application layer, business logic layer, DAO, database)

Single Service Disadvantage

Prone to global paralysis problems

Small problems can lead to overall deployment

Difficult to deploy frequently

Hard to keep up with the latest technology

Difficult to meet business incremental requirements

Load, build, understand, and maintain are time consuming

Micro-Service Benefits

Can solve the single service those shortcomings

Better fit with agile methods, CI/CD (Jenkins/teamcity/tfs/auzedevops)

Micro-Service Build pipeline

CI/CD build Process: Clean up Code, code compilation, perform unit tests, build application archives, deploy on various servers such as Dev QA, perform functions and integration tests, create image containers, any other steps, build release builds, Mark release versions

Docker container

Each container has its own user namespace

relies on basic operating system features (such as isolation services)

The application in the container can be developed in any language

Isolated from each other
