Course Introduction：The key to the implementation of service discovery lies in registration and query, and the commonly used client discovery model of Go microservices. 1. The selection of the registration center includes etcd, Consul, ZooKeeper, Nacos, etc., and the selection is based on team familiarity and technology stack; 2. Practical steps include service startup registration metadata, sending heartbeats regularly, and logging out when closed; 3. Service discovery methods include SDK direct connection, service grid sidecar, agents such as Envoy; 4. In terms of details, you need to pay attention to the registration timing, health check integrity, instance ID uniqueness and timeout retry mechanism.

Course Introduction：To build highly available Java applications, we need to consider comprehensively from architecture design, service governance to deployment, operation and maintenance. 1. Use microservice architecture to cooperate with load balancing (such as Nginx, SpringCloudGateway) to realize service isolation and automatic failover, and combine the fuse mechanism (Hystrix or Resilience4j) and service registration discovery (Eureka, Consul or Nacos) to improve system resilience; 2. Use master-slave replication and automatic switching tools (such as MHA, Patroni) at the database level to reasonably configure connection pools (such as HikariCP) and handle data consistency issues; 3. Implement fault tolerance and degradation mechanisms, use Resilience4j or

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
