Overall:

• Microservice design: java(spring boot) + RPC(RESTFUL) + database (db) + cache (redis) + configuration center (apollo)

• Microservice project implementation

• kubernetes deploys K8seasy: https://github.com/xiaojiaqi/K8seasy_release_page

• Microservice deployment

• High availability and monitoring High availability: multi-instance registry: eureka, zookeeper, console, Nacos (Note: deploying microservices in kubernetes does not apply to the registryAny restrictions) Monitoring (Metrics): Prometheus + Grafana (memory size, number of 200 errors, number of 500 errors, number of threads in the JVM, GC time size) Logging (Logging): write directly to the kafka component and directly enter the log center (the log does notAfter landing again, the log IO is eliminated, and the log storage is also separated from the container) Tracing: APM (cat, pip, zipkin, skywalkin), Zipkin needs to add a library to the project, and does not need to write code,This has done little intrusion on the business, and it is very convenient for flow control: circuit breaker, current limit and degradation, sentinel

• Service Grid and Data Persistence

• Stateful Services

• operator

Design

Consider:

System availability, reliability, robustness, scalability

Microservice Reference Architecture

Technical introduction

Principle of high observability

Apollo Configuration Center

Microservice DevOps platform with Kubernetes as a key link

Build and image push: Jenkins Pipeline or gitlab-runner Pipeline to complete

Workload access flow chart

Monitoring Components

Resource layer monitoring: Prometheus + Grafana + Node Exporter and other components to monitor the usage of CPU, memory, network, disk, etc. of Kubernetes nodes
Middleware layer monitoring: Prometheus + Grafana + MySQL Exporter + Nginx Exporter + JVM Exporteretc., monitor the usage of middleware such as MySQL, Nginx, JVM
Link/APM monitoring: monitoring tools such as Pinpoint / Skywalking to monitor the performance of the application
