This article introduces the knowledge of "what are the components of Go kit architecture". In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Overview of Go kit

Go kit (http://gokit.io) is a collection of Go packages that can help you build robust, reliable, and maintainable microservices. Go kit provides libraries of components for implementing system observability and resilient patterns, such as logging, metrics, tracking, rate limiting, and outages, which are basic requirements for running microservices in a production environment. The advantage of the Go toolkit is that it is opinionated and designed for interoperability between different infrastructure, message encoding formats, and transport layers.

In addition to building toolkits for microservices, it also encourages good design principles for application architecture in services. The Go toolkit can help you embrace solid design principles, domain-driven design (DDD) and the "hexagonal architecture" proposed by Alistair Cockburn, or one of similar architectural approaches, namely, the "onion architecture" proposed by Jeffrey Palermo and the "clean architecture" proposed by Robert C. Martin. Although Go kit is designed as a micro-service toolkit, it is also well suited for building an elegant whole.

Go kit architecture

There are three main components in the Gokit-based application architecture:

Transport layer

End layer

Service layer

Transport layer Transports

When you build a microservice based on a distributed system, the service usually uses a specific transport (such as HTTP or gRPC) or a publish / subscribe system (such as NATS) to communicate. The transport layer in Go kit is bound to concrete transport. Go kit supports various transport services using HTTP, gRPC, nat, AMQP and Thrift. Because Go kit services only focus on implementing business logic and do not understand specific transports, you can provide multiple transports for the same service. For example, a single Go kit service can be exposed using both HTTP and gRPC.

Terminal Endpoints

Endpoints are the basic building blocks for servers and clients. In Go kit, the main messaging mode is RPC. The endpoint represents a single RPC method. Each service method in the Go kit service is transformed into an endpoint for RPC-style communication between the server and the client. Each endpoint uses the transport layer to expose service methods to the outside world by using a specific transport, such as HTTP or gRPC. A single endpoint can be exposed by using multiple transports.

Service Services

The business logic is implemented in the service. The Go suite service is modeled as an interface. The business logic in the service contains core business logic, which should not contain endpoints or specific transports (such as HTTP or gRPC), nor should it include encoding and decoding of request and response message types. This will encourage you to follow a clean architecture for Go suite-based services. Each service method is transformed by using an adapter as an endpoint and exposed by using a specific transport. Because of the clear architecture, a single Go kit service can be exposed through the use of multiple transports.

Business logic is implemented in services modeled as interfaces. Here, we model our service with e-commerce domain order aggregation:
