What is Go?

Go, or Golang, is a statically typed, open-source programming language developed by Google. It is designed for simplicity, performance, and scalability, making it ideal for building efficient, concurrent applications like web services and cloud-based software. Go and Golang are the same language. The official name is Go, and "Golang" comes from its original website, golang.org, which is why many people use it when searching.

What is Golang used for?

These are the most common Golang use cases.

• Web development: Building high-performance web services and APIs.
• Cloud computing: Developing scalable and efficient cloud-based applications.
• DevOps tools: Creating infrastructure and automation tools.
• Microservices: Designing lightweight and maintainable microservices architectures.
• Networking: Building high-concurrency networking tools and applications.
• Distributed systems: Developing robust and fault-tolerant distributed systems.

When should you use Golang?

Golang is particularly well suited for applications where performance, concurrency, scalability, and efficient resource usage are important. Its simple syntax and built-in concurrency features make it a strong option for teams building systems that need to handle many operations simultaneously.

These are some common scenarios where Go can be a good choice.

• Backend services and APIs: Go's performance and straightforward approach make it well suited for building fast, maintainable backend systems.‍
• Microservices: Its lightweight runtime and fast startup times work well for distributed architectures composed of independent services. If you're exploring this approach, learn more about how microservices architecture works and its current best practices.
• ‍Cloud-native applications: Go is widely used across cloud infrastructure and container ecosystems, making it a natural fit for modern cloud environments.‍
• DevOps and infrastructure tools: Its portability and ability to compile into standalone binaries simplify deployment across different environments.‍
• High-concurrency applications: Goroutines and channels make it easier to build applications that need to manage many simultaneous operations.‍
• Distributed systems: Go's networking capabilities and concurrency model make it useful for services that communicate across multiple machines or environments.

However, Go is not automatically the best language for every project. The right choice depends on your application's architecture, performance requirements, existing technology stack, and your team's expertise.

Why use Golang? Advantages and benefits

Making the transition to Golang might be counterintuitive initially, as your code gets longer, but soon it becomes more readable, simple, and stable. These are the main advantages of Golang.

Golang = performance

Golang is a compiled language, meaning code compiles into a format the processor understands. Other languages, such as Java, require the code to be compiled into bytecode to be executed by the virtual machine.

‍

As a compiled language, Go can deliver strong runtime performance with relatively low resource usage. Its performance characteristics make it particularly well suited for backend services, APIs, cloud infrastructure, and other applications where efficiency and scalability matter.

Easy learning curve

Software developers with a solid foundation in languages such as Java or C often find Go relatively easy to learn. Its intentionally small language specification, straightforward syntax, and emphasis on readability can make it easier for developers to become productive quickly.

Well documented with an active community

Golang's official documentation is a comprehensive resource for developers, and the language has an active open-source community. This makes it easier to find libraries, tools, examples, and support when building with Go.

Golang is ideal for many diverse scenarios

Being a multipurpose programming language, Golang works well for web development, cloud computing, media platforms, streaming, networking, and more.

Golang is well-scaled

One of Golang's many strengths, goroutines, are functions that can run independently and simultaneously, giving Go its ability to support concurrency efficiently. Lean software is always a good idea and puts your business one step ahead of its competitors. Taking up no more than 2kB of memory, goroutines make applications built with Golang scalable when it's time to run multiple concurrent processes. While Java's thread, blocking by design, is a memory-hungry heavyweight, Golang's goroutines are non-blocking, making it technically possible to run millions of them without risking crashing the system. Also, less demanding system requirements translate into better support for older devices to enjoy Go-based apps.

Comprehensive programming tools

GitHub repository for Go is filled with various editors, IDEs, and plugins that you can download, while for those who prefer working on the go, a handful of cloud-based IDEs are also available. Being an open-source initiative, getting the proper development tools for your team will not be a concern. On top of an easy learning curve and friendlier code that's easier to learn, developers who chose Golang have several valuable tools to work with.

• GoDoc generating cross-referenced documentation automatically from code is made possible with GoDoc. 
• golangci-lint runs dozens of linters in a single pass and is the standard choice for static analysis in Go projects.
• Golang's simple API lets developers manage the environments necessary for easy testing and profiling.
• Race conditions associated with creating multi-threaded applications are easily identified using Go's built-in race detector.

Golang cons and limitations

Despite its advantages mentioned above, growing adoption, and popularity, Golang is not a perfect programming language. These are the main limitations of Golang to consider before using or migrating to Go.

More explicit code

Go favors explicit code over abstraction, so some tasks need more lines than in Python. Error handling in particular is verbose, which can slow early prototyping.

Smaller ecosystem for some use cases

Go has a strong ecosystem for backend development, cloud infrastructure, networking, and DevOps. However, its library ecosystem can be less extensive than those of more established languages in certain specialized areas, which may require teams to build additional functionality themselves.

Smaller talent pool

There are fewer senior Go engineers than Java or Python engineers, so hiring can take longer, especially in competitive US markets.

Golang pros and cons at a glance

Golang offers a strong combination of performance, simplicity, and concurrency, but like any programming language, it also comes with trade-offs. Here's a quick comparison of its main advantages and disadvantages.

Is Golang worth it for small teams?

Usually yes, when the product is a backend, API or infrastructure tool. Go's small language specification means a small team can keep the codebase readable as it grows, and compiling to a single binary keeps deployment simple without a dedicated DevOps engineer. It is a weaker choice if the team needs to prototype very quickly, relies heavily on data science libraries, or cannot hire Go experience. In those cases, starting with a language the team already knows and moving performance-critical services to Go later is a common path.

‍

For production servers under an intense workload and heavy demands, Golang is often the right fit. Some specific examples of Golang's successful adoption are these.

• ‍Cloud services providers: Popular cloud storage provider with over 500 million users, Dropbox uses it to manage its network, while Golang's creator itself, Google, relies on Go for its cloud infrastructure.
• ‍Media platforms: Two of the media heavyweights of the industry, YouTube and Netflix, use Go to manage the intense load on their services.
• ‍Online on-demand services: Reducing the time it took to provide its users with service was vital for Uber, which relied on Go to improve map processing speeds when users loaded geofence lookups.
• ‍Distributed network services: APIs, web servers, and frameworks for web applications need to handle concurrency efficiently. Golang's goroutines and channels are an ideal solution for developing network services.
• ‍Cloud-native development: High portability across various platforms, concurrency, and networking features position Go as an ideal language for cloud computing. Kubernetes, like many popular cloud platforms, was built with Go.
• ‍Replacements for existing infrastructure: In an attempt to modernize protocols and interfaces that had become obsolete over time, many old infrastructures were rewritten using Go. A new version of an internet protocol for clock synchronization among networks (NTP - the Network Time Protocol) was built on Go. 
• ‍News outlets: In use on the BBC site's backend, it was likely Go's capacity to optimize CPU usage that defined its adoption when managing a massive multimedia website. 
• ‍Utilities and stand-alone tools: When building small tools, Golang's full functionality with almost no dependencies makes it ideal for efficient building, packaging, and redistribution.

Is Golang worth learning?

For developers interested in backend engineering, cloud computing, DevOps, microservices, or distributed systems, Golang can be a valuable language to learn.

‍

One of Go's biggest advantages is that its relatively small language specification makes the fundamentals approachable, while its concurrency model introduces developers to concepts that are particularly relevant when building scalable systems.

‍

Learning Go can also be valuable for developers working with modern infrastructure technologies. If you're interested in containerized development environments, our Docker vs. Rancher comparison explores two popular tools used in modern development workflows.

‍

For companies, however, the decision is slightly different. Choosing Golang should depend on whether its strengths match the technical requirements of the product, including expected traffic, concurrency needs, infrastructure, scalability, and long-term maintainability.

Wrap up

Google created Golang as an answer to software issues of scalability, where hardware resources quickly become a limitation. After more than 15 years in production at companies like Google, Uber and Netflix, Go is a proven choice for backend and infrastructure work, though it is not the best fit for every type of application. Go's main strength is its effectiveness in dealing with bottleneck issues in processing time. Migrating to Golang is a wise option if you're planning on expanding e-commerce functionalities on your existing business or offering on-demand services. Adopting Go means avoiding the performance constraints often faced by thread-based programming languages.

‍

Reading code previously written by its creators is one of the daily struggles developers encounter when dealing with new features and software growth. Golang's easy-to-read code and beginner-friendly learning curve minimize time spent understanding previous code.

‍

If you're anticipating a surge in service demands that will crash the existing infrastructure capacity of your business, migrating to Golang is probably the best course of action, as Golang is ideal for companies with predictable growth who rely on quick server responses.
