Discuss the advantages of Go and the current status and trends of using Go in the Internet industry

With the continuous iteration and upgrading of Internet technology, more and more companies are choosing to use Golang (Go language) to develop applications. The advantages of high concurrency, distribution, and scalability make Golang gradually become the new favorite of the Internet industry. This article will start from the case of converting headlines to golang, and explore the advantages of Golang as well as the current situation and trends of using Golang in the Internet industry.

Toutiao to golang

As a well-known Internet company in China, Toutiao has attracted much attention due to its huge number of users and efficient recommendation algorithm. In terms of technical architecture, Toutiao uses languages ​​such as Java and Python for development. However, as the business continued to expand, Toutiao's technical team gradually realized that the original architecture could no longer meet its needs and needed to adopt a more efficient and scalable technology.

As a result, Toutiao began to consider using Golang to develop new applications. Specifically, Toutiao chose to use Golang to develop the real-time recall service in the recommendation system. By introducing Golang into the recommendation system, Toutiao can improve the performance and scalability of the recall service to better cope with the huge number of users.

Advantages of Golang

So, why do more and more companies choose to use Golang? We might as well take a look at the advantages of Golang:

1. High concurrency

One of the key features of Golang is high concurrency. The design of Goroutine and Channel allows developers to easily write concurrent code. At the same time, Golang's GC mechanism can automatically identify and reclaim unused memory, greatly reducing the probability of memory leaks.

2. Fast compilation

Another feature of Golang is fast compilation. In Golang, code is compiled into machine language and does not depend on external libraries. In this way, each modified code only needs to be recompiled once and can be run directly.

3. Good scalability

Golang’s standard library already contains a large number of tools and libraries to meet various development needs. In addition, Golang also supports C language calling and static linking, allowing developers to easily use libraries and tools written in other languages.

4. Efficient memory allocation and recycling

Golang’s memory allocation and recycling uses a more efficient algorithm, which reduces the time of garbage collection compared to languages ​​such as Java. and pressure. This makes Golang perform even better in scenarios such as high concurrency and large data volume processing.

The application of Golang in the Internet industry

In addition to headlines, in the Internet industry, more and more companies are beginning to use Golang for development. For example:

1. Uber

Uber has developed multiple back-end services using Golang. Among them, Uber’s Trip processing service is written in Golang.

2. Zhihu

Zhihu’s Back-end service also uses Golang. In addition, Zhihu’s Live service is also implemented using Golang.

3. Dropbox

Dropbox’s back-end services and some basic tools are also developed using Golang. For example, Dropbox’s streaming media processing and distribution service uses Golang.

4. Docker

Docker is a popular containerization software, and its back-end services are also developed using Golang.

Summary

In short, more and more Internet companies are beginning to realize the advantages of Golang and adopt this language for development. Characteristics such as high concurrency, distribution, and scalability make Golang the new favorite in the Internet industry. Of course, as an emerging programming language, Golang also has some shortcomings. For example, Golang's type system is relatively simple and lacks some advanced features. However, with the continuous development and improvement of technology, I believe that Golang will become the programming language of choice for more and more companies, let us wait and see.
