The Go language can develop the server side. It is positioned to develop "large-scale software". It is suitable for many programmers to develop large-scale software together. It has a long development cycle and supports cloud computing network services. As a server programming language, Go 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.
The operating environment of this tutorial: Windows 7 system, GO version 1.18, Dell G3 computer.
golang, which is the full name of the go language we are familiar with. Go language is the second open source programming language released by Google. Specifically optimized for programming multi-processor system applications, programs compiled using Go can be as fast as C or C code, are more secure, and support parallel processes.
The Go language is mainly used for server-side development. It is positioned to develop "large-scale software". It is suitable for many programmers to develop large-scale software together. It has a long development cycle and supports cloud computing network services. The Go language allows programmers to develop quickly, and as the software continues to grow, it makes it easier for programmers to maintain and modify it. It combines the efficiency of traditional compiled languages with the ease of use and expressiveness of scripting languages.
As a server programming language, Go 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 and API applications. , download applications, etc.; in addition, the Go language can also be used in the field of memory databases and cloud platforms. Currently, many foreign cloud platforms are developed using Go.
The application direction of Golang:
Blockchain technology: BT
Blockchain technology, also known as distributed ledger technology, is an Internet database technology that is characterized by decentralization, openness and transparency, allowing everyone to participate in database records.
Back-end server application:
# Supports the backend traffic of the main website (sorting, recommendation, search, etc.) and provides Load balancing, cache, fault tolerance, conditional offloading, statistical operation indicators Meituan
Backend applications of cloud computing/cloud services:
CDN’s scheduling system, distribution system, monitoring system, short domain name service, CDN internal open platform, operation report system and other small tools.
