What does golang mainstream do?

In today's programming field, Golang (or Go) has become a highly respected programming language. It is designed as a powerful yet simple programming language for handling high-concurrency, real-time, large-scale system and network applications. But what does Golang mainstream do? This article will introduce the main application areas and mainstream cases of Golang.

1. Cloud services and containerization

Golang is widely used in the field of cloud computing, especially in containerization. It is particularly closely integrated with Docker because both are launched by the same company. Golang's high performance, built-in concurrency, simplicity, and reliability make it one of the preferred languages ​​for building Dockerized applications. At the same time, Kubernetes is also a popular container orchestration tool, and Golang is also its core component, making it more stable and reliable.

2. Back-end development

Golang is widely used for back-end development, especially to handle CPU-intensive tasks and high-concurrency network requests. In back-end development, Golang's standard library provides a large amount of support, including common modules such as HTTP, TCP, WebSocket, JSON, XML, MySQL and MongoDB. Furthermore, Golang is designed to make it easy to write highly concurrent web servers, which is very important for real-time web applications and distributed systems.

3. Database processing and big data analysis

Golang is becoming more and more popular in data processing and big data analysis because it can not only easily integrate with various relational and NoSQL database integration can also handle the tasks of data orchestration and data processing processes well. Currently, Golang's mainstream database processing frameworks include GORM, xorm, beego and go-pg.

4. IoT and Embedded Development

Due to Golang’s lightweight nature and high performance, it is also an ideal language for IoT and embedded development. Golang's portability and reliability are key advantages in IoT projects, especially in aspects such as device communication, data collection and analysis. It can also easily integrate various sensors and devices, including Arduino and Raspberry Pi.

Mainstream cases:

1. Docker and Kubernetes

Docker is a popular containerization tool that uses Go to write its core code. Docker relies on the Go language compiler and its runtime library, making it fast and reliable at runtime. Kubernetes is also written in Golang and serves as the underlying component of container orchestration tools, providing fault tolerance and high availability capabilities.

2. Prometheus

Prometheus is a popular open source monitoring and alerting system for tracking the performance of an entire cluster. Written in Golang, it is efficient and scalable, capable of processing many metric data faster.

3. Etcd

Etcd is an efficient key-value storage system that makes communication in distributed systems easier. It is also written in Golang and uses a simple and efficient API.

4. CockroachDB

CockroachDB is a high-performance, scalable distributed SQL database that supports transactions and ACID features. It is written in Go and uses a distributed transaction structure to ensure data consistency.

Summary

Golang is widely used in fields such as cloud computing, containerization, back-end development, data processing, and the Internet of Things. The high performance, concurrency, reliability and simplicity of the Go language make it one of the preferred languages ​​for building high-performance, scalable and reliable applications. As more and more applications move to cloud services, containerization, and data analytics, we can expect Golang to continue to play an important role in the future.
