This article mainly introduces "what is the method of micro-service technology selection". In the daily operation, I believe that many people have doubts about the method of micro-service technology selection. The editor consulted all kinds of materials and sorted out simple and useful operation methods. I hope it will be helpful for you to answer the doubts about "what is the method of micro-service technology selection?" Next, please follow the editor to study!

Development language

JAVA

Mainstream programming language, suitable for building large-scale background services

Golang

Go is the second open source programming language released by Google in 2009. Specifically optimized for multiprocessor system application programming, programs compiled with Go can match the speed of C or C++ code, and are more secure and support parallel processes. Google has high hopes for Go. Its design is to make the software give full play to the advantages of synchronous multiplexing of multi-core processors, and can solve the trouble of object-oriented programming. At present, as the best choice in the field of cloud computing!

Develop IDE

IntelliJ IDEA

Jetbrains products, intelligent code assistant, J2EE support, various version tools (git, svn, github, etc.), JUnit, CVS integration, etc. Multilingual support, free version only supports a few languages such as JAVA. The flagship version is a paid version, with a free version (less functional than the flagship version).

VS Code

VS Code is a free, open source, high-performance, cross-platform, lightweight code editor, at the same time, in terms of performance, language support, open source community is also very good!

Flow control, fuse degradation

Sentinel

Alibaba's key open source projects, Java development, secondary development are convenient, and the community is active.

API Gateway

Spring Cloud Gateway

Spring is preferred, convenient for secondary development, and supports asynchronous non-blocking

Kong

Kong is a highly available API Gateway project based on the Nginx_Lua module, which is easy to expand and is open source by Mashape. Excellent performance, rich plug-ins, basic out-of-the-box use, the second opening has a certain threshold for use.

Configuration center

Nacos:

Alibaba's key open source projects can be used as a registration / center configuration center at the same time, simplifying the technology stack, improving the management interface, Java development, convenient secondary development, active community, and constantly updating iterations.

Apollo:

It is a distributed configuration center developed by Ctrip Framework Department, which can centrally manage the configuration of different environments and clusters. After configuration modification, it can be pushed to the application side in real time, and has standardized permissions, process governance and other features. It is suitable for micro-service configuration management scenarios.

Service discovery

Nacos:

Alibaba's key open source projects can be used as a registration / center configuration center at the same time, simplifying the technology stack, improving the management interface, Java development, convenient secondary development, active community, AP/CP model, and constantly updating iterations.

Zookeeper:

ZooKeeper is a distributed, open source distributed application coordination service, an open source implementation of Google Chubby, and an important component of Hadoop and Hbase; performance can meet large-scale service discovery and configuration center, high real-time performance, not suitable for large-scale real-time data synchronization scenarios; CP mode.

Monitor and control

Prometheus

More comprehensive open source monitoring system, CNCF technology stack, active community

Grafana

Grafana is an open source suite of metrics analysis and visualization. Pure Javascript development of front-end tools, through access to libraries (such as InfluxDB), display custom reports, display charts, and so on. Most of them are used in the monitoring of time series data, just like Kibana. Grafana's UI is more flexible, has rich plug-ins, and is powerful. The interface is simple and beautiful, supports free customization, and the community has rich Dashboard support.

SkyWalking

Distributed tracking system, domestic link tracking, rich community documents, Apache top-level projects.

Journal

ELK

Distributed service log processing, a log ecosystem built around elasticsearch. The utility model has the advantages of wide use and convenient expansion. With kibana, it is convenient to retrieve logs and locate online problems.

Middle of database

ShardingSphere

Apache ShardingSphere is positioned as relational database middleware, supporting data slicing, read-write separation, multiple data copies, data encryption, shadow library stress testing and other functions; community documents are rich, and it has become a top-level project of Apache.

Serialization

Jackson

Spring is preferred, stable and secure.

Protobuf

Protocol Buffer (abbreviated as Protobuf) is a lightweight and efficient structured data storage format of google, which can be used for structured data serialization and is very suitable for data storage or RPC data exchange format.

Using fastjson development tools to build tools is not recommended

Maven:

The mainstream project build and management tool, Maven is a pure Java development open source project under Apache, is a project build and management tool; it provides methods to help manage build, documentation, reports, dependencies, scms, release, and distribution. You can easily compile code, manage dependencies, manage binary libraries, and so on.

Gradle

Gradle is a project automation construction tool based on the concepts of Apache Ant and Apache Maven. The Gradle build script is written in the domain-specific language of Groovy or Kotlin. It can automatically handle package dependencies, automatically handle deployment problems, and write conditionally intuitively.

Interface request tool

Postman

Postman is a powerful Chrome plug-in for debugging and simulating sending HTTP requests. It supports almost all types of HTTP requests and is simple and convenient to operate.

Container

Docker

Is an open source application container engine based on the Go language and open source in accordance with the Apache2.0 protocol. Docker allows developers to package their applications and dependencies into a lightweight, portable container and publish them to any popular Linux machine. Using Docker can bring the following advantages: 1. Faster delivery and deployment; 2. Efficient deployment and expansion; 3. Higher resource utilization; 4. Simple management

Cluster management

Kubernetes

Kubernetes is an open source platform for automatic deployment, expansion, operation and maintenance of container clusters. With Kubernetes, you can respond to user needs quickly and effectively; deploy your applications quickly and expectedly; expand your applications rapidly; connect new application functions seamlessly; save resources and optimize the use of hardware resources. It provides a complete open source solution for container choreography management. The ecology is rich, easy to expand; the function is rich and stable, the big company endorses; easy to use.

Image management tool

Harbor

Harbor is an open source artifact repository. It is the first open source project originally created in China and has become a graduate of CNCF. Users can protect artifacts (such as container images, Helm Chart, etc.) through policies and role-based access controls, scan images and avoid security vulnerabilities. Harbor extends the open source project Docker Distribution, adding features that users need (such as security, identity, vulnerability scanning and management).

Operating environment operating system:

Linux

Linux is a free-to-use and free-spread Unix-like operating system. It is a multi-user, multi-task, multi-threaded and multi-CPU operating system based on POSIX and UNIX. It runs major UNIX tools, applications, and network protocols. It supports 32 bit and 64 bit hardware. Linux inherits the design idea of Unix with network as the core, and is a multi-user network operating system with stable performance.

Web server

Tomcat

Tomcat server is a free and open source Web application server, which is a lightweight application server. It is widely used in small and medium-sized systems and not many concurrent access users. It is the first choice for developing and debugging JSP programs.

Nginx

Lightweight Web server / reverse proxy server and email (IMAP/POP3) proxy server

NodeJs

Server-side JavaScript environment
