Why do we choose Go

There are many reasons to choose Go, and we have already covered many of the features and advantages of Go in previous documents. But the most important reason is based on the following two considerations:

  1. performance

    Shorten the API response time to solve the problem of batch request access timeout. In the business scenario of Uwork, a batch REQUEST of API often involves multiple calls to other interface services. However, under the previous PHP implementation mode, it is very difficult to achieve parallel calls, and serial processing cannot fundamentally improve the processing performance. But GO language is different, through the coroutine can easily realize the PARALLEL processing of API, to maximize the processing efficiency. Relying on Golang’s high-performance HTTP Server, the system throughput capacity has been improved from hundreds of LEVELS of PHP to thousands of miles or even more than ten thousand levels.

  2. Development efficiency

    GO language is simple to use, high efficiency of code description, uniform coding specification and quick to use. With a small amount of code, you can standardize the framework and quickly build API business logic with uniform specifications. It can quickly build various common components and public class libraries to further improve development efficiency and achieve mass production of functions in specific scenarios.

What can Go do

Since the release of version 1.0, Go language has attracted the attention of many developers and has been widely used. The simple, efficient and concurrent features of Go language have attracted many traditional language developers to join in, and the number is increasing.

In view of the characteristics and original design of Go language, Go language as a server programming language, is very suitable for processing logs, data packaging, virtual machine processing, file system, distributed system, database agent, etc. In network programming, Go language is widely used in Web applications, API applications, download applications, etc. In addition, Go language is also applicable to the field of in-memory database and cloud platform. At present, many foreign cloud platforms are developed by Go.

  • Server programming, Go is a good place to do things you used to do in C or C++, such as logging, data packaging, virtual machine processing, file systems, etc.
  • Distributed systems, database agents, middleware, etc., such as Etcd.
  • Network programming, which is currently the most widely used, including Web applications, API applications, download applications, and Go built-in NET/HTTP package basically we use the network functions are realized.
  • Database operations
  • Development of cloud platform, at present, many foreign cloud platforms are using Go development

Iii. Which enterprises 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 directly used Go for development. Recently, the popular Docker was developed using Go.

There are many open source projects developed using the Go language. Early open source projects of Go language are only implemented by binding C language library with traditional projects through Go language, such as Qt and Sqlite. Many of the later projects were implemented natively in Go, which was easier than other languages, leading to the emergence of a large number of native development projects using Go.

  • Cloud computing infrastructure

    Representative projects: Docker, Kubernetes, ETCD, Consul, Cloudflare CDN, Qiniu Cloud Storage, etc.

  • Based on the software

    Representative projects: TIDB, InfluxDB, CockroachDB, etc.

  • Micro service

    Representative projects: Go-Kit, Micro, TYPHON of Monzo Bank, Bilibili, etc.

  • Internet infrastructure

    Representative projects: Ethereum, Hyperledger, etc.

Some foreign companies that use Go, such as Google, Docker, Apple, Cloud Foundry, CloudFlare, Couchbase, CoreOS, Dropbox, MongoDB, AWS, etc.

Domestic enterprises using Go development: such as Ali Cloud CDN, Baidu, Xiaomi, Seven Cattle, PingCAP, Huawei, Kingsoft software, Cheetah Mobile, Ele. me and other companies.

Docker

Docker is an operating system-level virtualization technology that can isolate operating systems and applications, also known as containers. Docker can quickly run one or more instances on a physical server. LXC based on a virtual packaging tool, to achieve the PAAS platform. For example, starting a CentOS operating system and executing commands from its internal command line ends the whole process as efficiently as if it were operating on its own.

Write at the end

Of course, a technology can develop, the key to look at three points.

  • Is there a good neighborhood? Ecospheres like C, C++, Java, Python, and JavaScript are rich and hot. Especially communities that have a lot of commercial involvement, like the Linux community.
  • Is there a standard for industrialization? Things like C, C++, and Java are organized for standardization. Java, in particular, has developed enterprise-class standards such as J2EE in terms of architecture.
  • There is no one or more killer apps. The killer applications of C, C++, and Java are needless to say, even though PHP is not a good programming language, because it was the key technology in the first killer solution of the Linux era, LAMP, and so on.

These three things are very important, and new technologies only need one or two of them to be good, and some technologies, like Java, have all three, which is why Java is doing so well. Of course, in addition to the above three important factors, there are some other influencing factors, such as:

  • ** Is the learning curve low and fast? ** this is very important and C++ is getting worse and worse at this.
  • ** Is there a good development framework to improve development efficiency? ** such as: Java Spring framework, C++ STL and so on.
  • Is it backed by one or more giant technology companies? ** IBM and Sun behind Java and Linux…
  • Does ** address pain points in software development? ** For example, Java solves the memory management problems of C and C++.

Using these scales to measure the Go language, we can clearly see:

  • Go is easy to learn;
  • Go language solves the pain points of concurrent programming and writing the development efficiency of low-level applications.
  • Go has Google, the world’s leading technology company, behind it;
  • The killer app for Go is Docker, whose ecosystem has exploded in recent years.

So the future of Go is limitless. Of course, I personally feel that Go will devour a lot of C, C++, Java projects. However, the main projects devoured by the Go language should be middle-tier projects, neither very low-level nor business-tier.

That is, the Go language does not devour projects down to the C and C++ levels, or at higher levels such as the Java business layer. Go language must swallow the projects on PaaS, such as some message caching middleware, service discovery, service proxy, control system, Agent, log collection, etc., there is no complex business scenario, nor can Go to the middle platform layer of software projects or tools, such as operating system. C and C++ will be pushed down to the bottom, and Java will be pushed up to the business layer.

Ok, let’s measure Go’s killer app Docker again with the above yardstick, and you’ll see the same thing.

  • Docker is easy to get started with.
  • Docker solves the environmental problems in operation and maintenance and the pain points of service scheduling.
  • Docker’s ecosystem has big companies behind it. Such as Google.
  • Docker produces the industry standard OCI.
  • The Docker community and ecosystem are already showing the same momentum as Java and Linux.
  • …

Therefore, although Docker a few years ago had many potholes at that time, compared with these big factors, those small potholes were not a problem. It just takes some time, and these holes will be completely filled in the next 5-10 years.

Also, we can see that Kubernetes will be the ultimate winner as a key technology for service and container scheduling.

Finally, I want to talk about why it’s important to get into these new technologies earlier rather than waiting for them to mature. There are several reasons.

The process of technological development is very important. Because you can clearly see the ecosystem of this new technology. What we gain most is not the technologies themselves, but a technological change and the development of the industry.

We see very specific thoughts and ideas that are more valuable than the technology itself. Because not only does it make us rethink the technology we already have and how we can better solve the problems we already have, but it also gives me a glimpse into the future. Not only do we have technical advantages, but this knowledge also makes our technical career more possible.

These key new technologies give you a head start on technology. These are all very important for an individual or company that needs technical leadership.

If one company or individual has a technological head start, it can have a greater impact than others. Once the industry demand explodes in the future, the influence of the company or individual will form a relatively large moat and generate economic benefits quickly.

Go’s application scope is expanding all the time, cloud computing, microservices, blockchain, where Go write heavyweight projects. The Docker/Kubernetes ecosystem, hundreds/tens of millions of lines of code, basically dominates the cloud native app market. Last year’s hot blockchain, Geth of Ethereum, BTCD of Bitcoin, LND of Lightning Network, are all developed in Go language. Again, take a look at the ecology of various languages and it may not be as bad as you think… Go isn’t “advanced” in its design, but it’s also “pragmatic” in a different way. In fact, go has been very popular both at home and abroad. Google is widely used in foreign countries and Uber is also used. There are famous headlines in China today, and the daily visits of hundreds of billions of people are no problem. Not many languages have such a large application scenario in their lifetime.
