CloudWeGo Demo for Business

This repo contains CloudWeGo demos with business logic, providing valuable references for enterprise user using in production.

Each demo should/may contain multiple CloudWeGo subprojects, e.g. Kitex & Hertz, and demonstrate an individual business scenario.

Demo List

1. Bookinfo

Description

What is it about and what problem does it solve?

• How to use kitex proxyless in istio?
• How to implement full-process traffic lane using CloudWeGo?

What is the business scenario?

Rewrite Bookinfo project using hertz, kitex, same as the Bookinfo

The application displays information about a book, similar to a single catalog entry of an online book store. Displayed on the page is a description of the book, book details (ISBN, number of pages, and so on), and a few book reviews.

The Bookinfo application is broken into four separate microservices:

• productpage. The productpage microservice calls the details and reviews microservices to populate the page.
• details. The details microservice contains book information.
• reviews. The reviews microservice contains book reviews. It also calls the ratings microservice.
• ratings. The ratings microservice contains book ranking information that accompanies a book review.

What are the core technologies/projects used?

• Use istiod as xDS server for CRD configuration and distribution
• Use wire for dependency injection
• Use opentelemetry for tracing
• Implement proxyless flow lane with Kitex-xds and opentelemetry baggage
• Implement a bookinfo ui using arco-design react

Which CloudWeGo subprojects are used? List all technologies used.

• Kitex
• Hertz
• kitex-xds
• kitex-opentelemetry
• hertz-opentelemetry

2. Open Payment Platform

Description

What is it about and what problem does it solve?

• How to use kitex generic call as the http gateway?
• How to implement Clean Structure of Go using kitex?

What is the business scenario?

The application demonstrates the usage of kitex generic call.

• We build the generic call client for each backend server by traversing IDL in Hertz.
• Hertz will accept the requests with the query path of prefix /gateway .
• Gateway handler will process these requests and route them to backend server by generic call client.
• payment server is just a sample server using kitex.This service design pkg with Clean Structure.

What are the core technologies/projects used?

• Use Hertz as Gateway.
• Use Kitex generic call client route requests.
• Use Kitex as RPC framework to build micro-services.
• Use Clean Architecture for design pkg and code layout.
• Use ent entity framework for implementing repository.
• Use wire for dependency injection
• Use Nacos as service registry.
• Use MySQL as RDBMS.

Which CloudWeGo subprojects are used? List all technologies used.

• Kitex
• Hertz
• kitex-layout(coming soon)

3. Easy Note

Description

What is it about and what problem does it solve?

• How to get started with Hertz and Kitex collaboration?
• How to structure projects when using Hertz and Kitex?

What is the business scenario?

Migrate easy_note and optimize the project.

The application shows a note service that allows users to create, delete, update, and query notes.

The easy_note application is divided into three microservices:

• demoapi is an HTTP service that handles HTTP requests and calls other services via RPC.
• demouser is an RPC service that handles user related operations.
• demonote is an RPC service that handles note related operations and calls demouser service via RPC.

What are the core technologies/projects used?

• Use hz and kitex to generate code
• Use Hertz requestid, jwt, pprof, gzip middlewares
• Use go-tagexpr and thrift-gen-validator for validating HTTP and RPC request
• Use obs-opentelemetry for tracing
• Use etcd as service registry.
• Use GORM for implementing repository.
• Use MySQL as RDBMS.

Which CloudWeGo subprojects are used? List all technologies used.

• Hertz
  • obs-opentelemetry
  • requestid
  • jwt
  • pprof
  • gzip
• Kitex
  • obs-opentelemetry
  • registry-etcd
• thrift-gen-validator

4. Book Shop

Description

What is it about and what problem does it solve?

• How to integrate middlewares(such as ElasticSearch, Redis...) in Kitex project?
• How to layer code in projects of different complexity using Hertz and Kitex?

What is the business scenario?

The application shows an e-commerce system that includes merchants managing items, consumers managing personal accounts and placing orders to buy items.

The book-shop application is divided into four microservices:

• facade is an HTTP service that handles HTTP requests and calls other services via RPC.
• user is an RPC service that handles user managements.
• item is an RPC service that handles item managements.
• order is an RPC service that handles order managements.

What are the core technologies/projects used?

• Use Hertz as Gateway.
• Use Kitex as RPC framework to build microservices.
• Use Hertz swagger, jwt, pprof, gzip middlewares.
• Use ETCD as service registry.
• Use MySQL as RDBMS.
• Use Redis as cache.
• Use ElasticSearch as search-engine.

Which CloudWeGo subprojects are used? List all technologies used.

• Hertz
  • swagger
  • jwt
  • pprof
  • gzip
• Kitex
  • registry-etcd
• sonic

5. FreeCar

Description

What is it about and what problem does it solve?

• How to use the idea of domain-driven development to develop in Kitex?
• How to develop Hertz and Kitex through RPC + AGW mode?

What is the business scenario?

Time-sharing car rental system kit in the cloud-native era.

The FreeCar application is divided into six microservices:

• api is an HTTP service that handles HTTP requests and calls other services via RPC.
• user is an RPC service that handles user related operations.
• profile is an RPC service that handles profile related operations.
• blob is an RPC service that handles blob related operations.
• car is an RPC service that handles car related operations.
• trip is an RPC service that handles trip related operations.

What are the core technologies/projects used?
