When choosing a programming language for cloud development, Golang stands out as a top choice. Introduced by Google in 2009, Golang combines simplicity with performance, making it a preferred language in modern software development. In this article, we delve into Golang’s unique features, benefits, limitations, and assess its value within the developer’s toolkit.
Why Google created Golang
The development of Golang, or Go, started in 2007, during Google’s rapid expansion. As Google grew, so did the complexity of its infrastructure code, which slowed operations. Recognising this, engineers Robert Griesemer, Rob Pike, and Ken Thompson set out to create a new language that emphasised speed and simplicity. This led to the birth of Go. Released as an open-source project in 2012, Go quickly gained popularity among developers. Today, it ranks #10 on the TIOBE programming community index.
The origin of Golang, more commonly referred to as Go, began in 2007 when Google was experiencing a period of rapid expansion. As the company grew, so did the code that was being used to manage its infrastructure, adding a layer of complexity that slowed down operations. Recognising the need for a fresh approach, cloud engineers Robert Griesemer, Rob Pike, and Ken Thompson embarked on crafting a new programming language designed around two key objectives: quick performance and simplicity. Thus, Go was born. In 2012, Go became an open-source project, and version 1.0 was officially released to the public, where it rapidly garnered a surprising level of popularity among developers. Today, Go remains one of the leading modern programming languages, currently ranking at #10 in the TIOBE programming community index.
What is Golang used for?
Initially built for networking and infrastructure, Go was positioned as a successor to server-side languages like Java and C++. Today, Go is used across a variety of domains, including cloud-based applications, DevOps, automation, AI, and data science. It extends to niche areas like microcontroller programming, robotics, and game development. However, Go truly excels in infrastructure, powering key tools like Kubernetes, Docker, and Prometheus.
How Golang differs from other languages
While the programming landscape is vast, Golang has unique qualities that set it apart from languages like Python, Java, and C++. Here’s what makes it stand out:
4 benefits that give Go its edge:
Simplicity: Go’s straightforward design is easy to learn, especially for developers with basic programming knowledge. Many can read its entire spec in an afternoon.
Speed: Go’s simplicity and efficiency enable fast execution, making it ideal for replacing bash scripts or Python scripts.
Versatile performance: Go compiles on nearly any machine, enabling developers to build high-performing applications for scalable, cloud-based servers
Innovation: Go is regularly updated, with new versions every six months, expanding its library ecosystem and functionality.
Challenges with Golang
Despite its strengths, Golang has limitations, including:
- Limited libraries: Go’s libraries are expanding, but it still lacks the extensive library support seen in languages like Java and Python.
- No inheritance: Go doesn’t support traditional object-oriented programming (OOP). It relies on composition and interfaces instead of inheritance.
- Small community: While growing, Go’s community is smaller than those of more established languages, which can limit collaboration and support.
Is Golang right for your project?
Golang is an ideal choice for cloud-native applications, serverless computing, and edge computing. Its low resource consumption and fast startup times make it suitable for sustainable, serverless microservices. Businesses with predictable growth and fast server response requirements will benefit from Go’s efficiency and versatility. If you’re seeking a high-performing language with a vibrant, growing community, Go is a strong option.
5 key takeaways:
- Golang’s growth: Launched by Google in 2009, Golang has rapidly become a top programming language known for its simplicity and performance.
- Versatile applications: Go’s use extends from cloud development to microcontroller programming, showcasing its versatility.
- Core benefits: Simplicity, speed, versatility, and regular updates make Go a standout programming language.
- Challenges: Go’s limited libraries, lack of inheritance, and smaller community are considerations for new developers.
- Project suitability: Golang is well-suited for cloud-native applications and sustainable development, especially for businesses requiring fast server responses.
