What Is Golang Used For? 7 Examples of Go Applications

Your business might be juggling a million things, such as scaling your tech, improving performance, cutting costs, and maintaining teams. However, no matter how much you try, if your current tech stack is the problem, your progress will be hampered. Perhaps your app’s performance isn’t smooth, or growing demands are causing your progress distress.

If any of this sounds familiar, you should consider using the Go programming language. As per Data Landbase, 9,214 verified companies are using Golang across industries and geographies. Many of the top companies like Uber, PayPal, and Twitch have changed their tech systems to it.

If you’re still unsure about its uses, we’re here to help you. Read our blog to understand what Golang is used for and real-world Golang use cases that helped businesses tackle performance issues in their system without going over budget.

What is Golang Used for?

We understand choosing a new language or technology can be confusing in the beginning. But knowing what the Go language is, what its usage is, and how it can help your business can give a clear picture. It was created to compete with server-side giants like C++ and Java, and now it has become a go-to solution across different industries.

Let’s dive into some of the areas where Golang applications are used to address business problems:

1. Distributed Systems

As the business grows, managing complex systems becomes difficult. Businesses often work with distributed systems, where different parts of your application communicate across multiple servers. This can be a challenge to keep everything coordinated and functioning properly.

How Golang Can Help:

Go is the right choice when it comes to distributed systems. Its built-in features, like goroutines and channels, make it simple to run multiple tasks without slowing things down. It not only builds faster but also handles large-scale data. Plus, it provides the speed and reliability you need to run systems smoothly.

2. Site Reliability and DevOps Automation

The motive of any app is to keep it running 24/7. But automating systems while maintaining stability and performance can be a challenge. It can seem like you’re always behind with constant updates and scaling.

How Golang Can Help:

It is widely used in DevOps because of its fast, reliable, and easy integration. Go simplifies your process with its continuous integration, automates operations, and monitors system health. It helps to build tools, automate tasks, and keep things running smoothly.

3. Network Servers

Network servers that handle multiple connections at once can lead to performance issues. As your app grows, managing these high traffic loads with scalability and low latency can be a critical task.

How Golang Can Help:

It is ideal for building network servers that need to scale. It has a variety of built-in networking capabilities that can handle multiple concurrent connections while taking care of response time. Its lightweight architecture and support help to perform better even during heavy traffic.

4. Command Line Tools

Command-line tools are crucial for many businesses to handle deployments, manage databases, and automate tasks. However, these tools can slow down your process as they can be complex.

How Golang Can Help:

Its speed and easy development are its strongest points, which make it ideal for creating command-line tools quickly. It ensures that whatever tool you use is quick, dependable, and scalable.

7 Examples of Go Applications

Now that we’ve discussed what it is used for and how it can help, here we’ll examine some real industry Golang examples to understand how it improved their businesses. This section will help you understand how it can also make a change in your business if implemented with the right strategy and experts. Let’s dive in!

#1 eCommerce

Let’s say you’re running a major online store. Millions of people surf your site at once at peak sales time. If your backend slows down during this period, your sales and trust will be lost. That’s when Go can help. It's perfect for high-traffic eCommerce systems as it handles concurrent requests easily.

For example, Alibaba Group uses Go for their container engine, PouchContainer. It makes it easy to package, deliver, and run just about any application. Plus, PouchContainer runs 10,000 nodes for Alibaba, helping in online transactions smoothly.

#2 Online Booking Systems

Suppose you run a travel booking system or an on-demand service app (rides, accommodations, appointments). You get a sudden traffic when people check availability, make payments, and make reservations all at once. Golang is designed for that type of workload.

For example, Uber has mostly relied on Python and Node.js over the years. But lately they have shifted to Go for developing Uber Engineering’s new services. Uber has already written over 100 services in Go. This service helps match riders with drivers and shares those matches across devices.

#3 Finance

When it comes to the finance sector, there’s constant demand for real-time financial data. That’s where Go can help, as it’s a great fit to access data, manage transactions, and keep everything secure from unauthorized access.

Take the example of Capital One. This is a tech-driven financial company that uses Go for its Credit Offers API. It helps their services run smoothly and securely.

#4 Payment Processing Systems

Another industry that utilizes Go is payment processing, where it runs anti-fraud checks to ensure secure transactions. The industry demands continuous dependability, 24/7 operations, and automatic recovery, and Go delivers it.

For example, PayPal is one of the leading payment processors that relies on over 100 Go developers to run its system globally. Its speed, reliability, and scalability make it the preferred language for many of PayPal’s vital applications.

#5 Technology Platforms

The main goal of technology platforms is to speed up and improve the efficiency of app development. It helps businesses to deploy solutions quickly. Go fits here perfectly with its reliability and smooth performance.

Just like with Dropbox. They initially relied on Python for its speed in iteration, but faced challenges as their user base expanded. They switched from Python to Go for its performance-critical backend to scale effectively. This benefited them in improving concurrency support and quick execution time.

#6 Instant Communication Platforms

When developing chat and messaging platforms, concurrency and scalability are crucial. Go makes it easy for chat and messaging apps. It’s also a great choice for advanced apps, with its growing role in AI development.

For example, Stream has a robust activity feed and chart platform, which is used by billions of people. With Go, it has scaled seamlessly and delivered outstanding performance. Today, Stream has about 500 million users.

#7 Cybersecurity

Privacy and security are top of mind for everyone, and the cyber market is growing fast to keep up. Even here, Go’s speed and static typing make it an ideal option. It is widely used in server and cloud environments, which makes it even more popular in the industry that prioritizes security.

For example, 1Password is trusted by over 60,000 businesses globally to protect their data. And you know what? They use Go for their backend. It powers their systems and keeps everything secure, and gives admins full control over recovery and security. If you want strong privacy measures, use Go.
