Why Golang is Perfect for Building Microservices published 3/16/2023 | 3 min read

Microservices architecture is a popular and effective way of building modern, scalable, and modular software applications that can serve the needs of the cloud-native era.

While there are several programming languages out there that are suitable for building microservices, Golang (or simply, Go) has become a popular choice among developers in recent years. In this article, we'll explore why Golang is perfect for building microservices and the key advantages that it brings to the table.

1. High Performance

One of the primary benefits of Golang is its outstanding performance. Golang was designed to be a high-performance language that runs efficiently on modern hardware. The language is also optimized for multi-core processors and distributed systems, making it perfect for microservices architecture.

Golang uses a simple and concise syntax and has a garbage collector that runs concurrently with the application code, which helps to reduce the number of pauses or delays in the execution of an application. This high-performance behavior of Golang makes it an ideal choice for building microservices that can handle large amounts of data and high traffic.

2. Lightweight

Another significant advantage of Golang is its lightweight nature. Golang binaries are small, which reduces the memory footprint of microservices built with the language, leading to faster deployment and simpler maintenance. The language is designed to have minimalistic features, which makes it easy to learn and understand, making the development process faster and more efficient.

3. Concurrency and Multi-threading

Concurrency and multi-threading are essential features of any microservices architecture, and Golang was designed with these aspects in mind. Golang has built-in support for concurrency, which makes it easier to write concurrent code without worrying about race conditions and deadlocks.

Golang uses Goroutines, which are lightweight threads that run concurrently and can communicate with each other through channels, effectively simplifying the development of concurrent or parallel applications.

4. Easy to Read, Write, and Maintain

Golang code is easy to read, write, and maintain, which reduces the overall development time and cost. The language has a simple, concise syntax that is easy to understand, making it ideal for developers who are transitioning from other languages.

Golang is also statically typed, which means that the compiler can catch errors at compile time, thereby reducing the number of runtime errors. This leads to more stable, efficient and maintainable codebases, which are essential traits for microservices architecture.

5. Large Standard Library

Golang has a large and growing standard library that provides developers with built-in support for various tasks, such as networking, encryption, and database access. This makes it easier and faster to develop microservices without the need for third-party packages or libraries.

The standard library also includes a powerful HTTP server, which is essential for building REST APIs and other web-based microservices.


Golang provides a perfect balance between performance and ease of use, making it an ideal choice for building modern microservices. Its lightweight nature, built-in concurrency, and large standard library simplify the entire development process, leading to faster and more efficient software development.

While Golang may not be the only language suitable for building microservices, it certainly stands out for its scalability, performance, and maintainability, thereby making it one of the best choices in the market.
