What can the go language do?

What the go language can do: 1. Server programming; as a server programming language, the Go language is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, database agents, etc. 2. Develop distributed systems, database agents, middleware, etc., such as Etcd. 3. Network programming, including Web applications, API applications, download applications, and Go's built-in net/http package basically implements all the network functions we usually use. 4. Database operations. 5. Develop cloud platforms. Many foreign cloud platforms are using Go development.

The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.

The Go language, also known as Golang, is a statically strongly typed, compiled, concurrent, and garbage collection programming language developed by Google.

Why choose Go language

There may be many reasons for choosing Go language. Regarding the characteristics and advantages of Go language, we have discussed it before A lot has been introduced in the documentation. But the main reason should be based on the following two considerations:

• Execution performance

  After all, it is a C-like execution speed. For some services, performance is an extremely important part, related to system throughput and access delay, which will in turn affect user experience. Go language can easily implement parallel processing through coroutines to maximize processing efficiency and improve System throughput capacity.

• Development efficiency

  GO language is easy to use, has high code description efficiency, unified coding standards, and is quick to get started. With a small amount of code, the standardization of the framework can be achieved, various general components and public class libraries can be quickly constructed, further improving development efficiency, and achieving mass production of functions in specific scenarios.

What can the Go language do

The Go language has attracted the attention of many developers since the release of version 1.0 and received Widely used, the simplicity, efficiency, and concurrency features of the Go language have attracted many traditional language developers to join, and the number is increasing.

In view of the characteristics of Go language and the original intention of its design, Go language, as a server programming language, is very suitable for processing logs, data packaging, virtual machine processing, file systems, distributed systems, database agents, etc.; in terms of network programming, Go language is widely used in Web applications, API applications, download applications, etc.; in addition, Go language is also suitable for in-memory database and cloud platform fields. Currently, many foreign cloud platforms are developed using Go.

• Server programming, if you used C or C to do those things in the past, it is very suitable to use Go to do it, such as log processing, data packaging, virtual machine processing, file system, etc.

• Distributed systems, database agents, middleware, etc., such as Etcd.

• Network programming, this area is currently the most widely used, including Web applications, API applications, download applications, and Go’s built-in net/http package basically integrates the network functions we usually use All realized.

• Database operation

• Develop cloud platform. Currently, many foreign cloud platforms are using Go development

Which companies or projects at home and abroad use Go language

After the release of Go, many companies, especially cloud computing companies, began to use Go to reconstruct their infrastructure. Many of them are developed directly using Go. Docker, which is in full swing recently, is developed using Go.

There are many open source projects developed using Go language. Early Go language open source projects only implemented C language library binding between Go language and traditional projects, such as Qt, Sqlite, etc.; many later projects used Go language for re-native implementation. This process is simpler than other languages. This has also contributed to the emergence of a large number of native development projects using the Go language.

• Cloud computing infrastructure field

  Representative projects: docker, kubernetes, etcd, consul, cloudflare CDN, Qiniu cloud storage, etc.

• Basic software

  Representative projects: tidb, influxdb, cockroachdb, etc.

• Microservice

  Representative projects: go-kit, micro, typhon of monzo bank, bilibili, etc.

• Internet infrastructure

  Representative projects: Ethereum, hyperledger, etc.

Some foreign companies that adopt Go, such as Google, Docker, Apple, Cloud Foundry, CloudFlare, Couchbase, CoreOS, Dropbox, MongoDB, AWS and other companies;

Adopt Domestic companies developed by Go: companies such as Alibaba Cloud CDN, Baidu, Xiaomi, Qiniu, PingCAP, Huawei, Kingsoft, Cheetah Mobile, Ele.me, etc.
