In this article, I will introduce five of the best programming languages for DevOps, and the resources that have been most useful to me as I have added these development skills to my set of infrastructure tools.
Advanced levels of automation allow for continuous integration / continuous delivery (CI / CD) practices that were not possible in the past. CI / CD workflows facilitate application delivery: a developer can push their code to a source repository and the infrastructure is automatically deployed to support testing processes that can push an application to production without human intervention. The work of a technologist crawling under the slabs of a raised floor to connect new network cables is no longer in the critical path for the deployment of production applications.
Java has been around for a long time and is still widely used. Due to its ability to run anywhere once written, it’s easy to see why it would be so popular. So many versatile platforms are based on Java, it’s hard to imagine not adding Java to your skill set.
Python has become an all-purpose language in infrastructure. It has been used to build cloud infrastructures projects such as OpenStack, and even supports web applications through frameworks such as Django. Python is an approachable language with a wide range of uses.
Ruby is used in a number of infrastructure projects. ManageIQ, for example, is a Ruby on Rails app. At my job at Red Hat, I often joke with customers that with ManageIQ (and CloudForms), users are only 10 lines of Ruby code away from doing anything.
The Go language was introduced in 2009, and has made quite a splash in the market since its introduction. The designers of the language were focused on making a statically typed language that is human readable, but that also performs well at scale.
C is a language I have tried to learn several times. Each time I approached C, I didn’t have any particular goal in mind. I wanted to learn the language because so much of the code in the world is written in C, and many of the constructs in the language are reused in other languages. When I joined Red Hat, however, I quickly learned an adage that’s been in the FOSS community for a very long time: The best documentation is the code. As I have sought to understand projects such as KVM, libvirt, and QEMU, I realized that I need to learn C to understand what’s happening at a fundamental level.
Perl is a great skill to have for DevOps. Perl can be used at all sorts of applications — going from low-level tasks to high-level projects. Perl can be applied to just about anything because of its cross-platform functionality.
In this post, i have explained How To Top programming languages for DevOps in 2020.
