We have been discussing about the trends in DevOps through a series of blogs and next on line is ‘Go Lang’ which is an open source programming language that improves the programming practice. It is one of the most popular languages and DevOps is all set to increase Golang usage by 19% in the near future. With the tremendous increase in projects and workloads, the complexities also increase invariably. Using Go, you can resolve these complexities with tooling that aids smooth operations and better observability.
- You can now write codes once and easily run it on multiple platforms at any time
- Compiling codes is easy and faster enabling cross-compiling where various teams run these codes on different platforms
- You can write it easily and Like how Google backs k8s, it also backs Go
- You can witness high performance with a strong support of library consisting of all relevant data
Why is Go the need of the hour for DevOps
Go works on environments where teams want to remove dependencies as Go acts as a stand-alone binary. You can execute things without actually having to set up a system an environment in a much faster way than other languages with Google backing it up. Reemphasizing the fact that it is easy to write and understand, even a new comer would get the catch of this language quickly saving you more time on resource training. This programmable language has high potential to become a dominant language soon. Organizations today demand for scalable systems with great support services, lesser scripts and strong development platform that supports concurrency. Go language is widely used with DevOps open source tools like Kubernetes, Prometheus, where these are rewritten with Go. Also, there are tools written in Go directly like Helm, Grafana, etc.
Let’s check out these tools in detail.
Kubernetes: As a container cluster management tool, ensures that Docker containers run by order and track the time and place of the job running through the tracking and finding process. Though C, C++, Java or python are great to work with, these could be challenging for the systems in case of installations and runtime complexities. The simple Go consists of quality libraries with all relevant data which enables us to pick out anything when needed. The fact that it helps in faster building and testing eventually, results in faster software deployment that any organization would game for. Also, with Go it is easy to connect to various networks under priority avoiding the rest.
Prometheus: This open source monitoring tool with service discovery supports monitoring and alerting the environments. It consists of robust libraries made of Go scripts that can collect and expose service metrics with the help of core metrics such as counter, gauge and histogram. Using new configuration lines, you can shift from one solution to the other with Go and it aids in understanding the complete behavior of the environment and application and thereby, influence decisions for improvements.
Helm: with the increase in number of releases, it could be complex for Kubernetes to handle it alongside other resources and attributes. You can resolve this condition by using Helm as it packs everything into a single application and assigns parts for configuration depending on requirements. Helm can install, upgrade, configure and fetch software packages through its components and curate repository of charts.
Grafana: An open source monitoring and analysis tool to support data sources which can be used with Prometheus to showcase service metrics. While, it uses java scripts to code, Go language supports the backend strongly. As it is a stand-alone binary, it is easy to deploy besides, its scripts are simple and makes the backend and programming accessible. It stands out for its TV mode where it disintegrates the display into sections to show the metrics in sequence automatically.
To sum up we can say that Go programming language is simple enough to building software faster and ensure if all jobs are running as they should. You can consider Go for more than coding with the right choice of tool in DevOps and our DevOps consulting services will help you do that. Go, topping the list of languages in high demand according to Hired 2019 state of software engineers report, is used in most of the popular tools focusing on DevOps as it evolves with time.
