Top 5 programming languages ​​for network admins to learn


Network admins can discover themselves unfold a bit skinny throughout these occasions of distant work whereas attempting to present help for all customers. Leveraging programming to automate widespread duties might assist.

In the primary article on this sequence specializing in the top 5 languages ​​for systems admins, I wrote about not being too keen on programming. To recap, it is not as a result of I do not see the worth behind it, as a result of I do whole-heartedly do. I imply, creating your individual apps to handle shopper gadgets and make them do precisely what you need them to do is unbelievable so far as I’m involved. My hesitation stems partly from frustration as it is not pure expertise for me and might — at occasions — take me a while to develop the answer I want.

But it’s totally cool whenever you get that script refined, examined, and put into manufacturing to deal with redundant duties that may in any other case saddle your workload. Now greater than ever, I’ve personally been leaning extra closely on automation since I discover myself carrying a couple of hats whereas working remotely and supporting any variety of departments, customers, and stakeholders in new and diverse methods.

It’s with this spirit I current this text with the give attention to network directors and engineers. The duties and initiatives that web admins encounter will profit from any of those programming languages ​​under. But in case you’re wanting to transition into one other position, these languages ​​will even serve you properly, maybe even presenting alternatives you were not conscious of shifting ahead.


The Perl programming language has been around for greater than 30 years, and it has continued to be in growth, discovering itself at dwelling and totally able to managing methods, networks, and net servers concisely and effortlessly. As a matter of reality, Common Gateway Interface (CGI) scripting led to its rise in recognition as extra providers discovered their approach to the web, with Perl’s skill to execute packages on net servers to dynamically generate websites.

But there’s much more to Perl, akin to how the language naturally lends itself to network administration and methods administration via open supply help coupled with system-agnostic design. Perl is colloquially referred to as, “the duct tape of the Internet,” due to its versatile nature when dealing with information (particularly giant information units) and permitting programmers to rapidly develop fixes to issues. Adding to its sturdy nature, the event of Perl purposes is usually sooner than different, extra fashionable languages. But that creates a difficulty because the number of syntaxes typically makes resolving Perl-related coding points arduous for the inexperienced.

Roles are finest suited to Perl customers are Unix and Linux directors, database directors, net directors, and builders.


The native shell of Unix-based methods, together with Linux and macOS, is the command-line interface (CLI) that enables admins to execute instructions utilizing extremely intricate syntax to create scripts to automate system processes, whether or not they be generally carried out duties, upkeep cycles akin to upgrades and automating system setup duties to guarantee methods are all configured and managed in the identical style.

For networking tools, plenty of merchandise run on some type of Linux-based OS, which permits for quite a lot of flexibility to handle gadgets in a structured, safe method. Furthermore, by studying to leverage terminal instructions to automate processes, web admins may use the exact same instructions to run exams on the network itself to decide connectivity and information routes as well as to log creation for monitoring gadgets and their connections.

Roles finest suited to Bash (Bourne Again SHell) programmers embrace Linux and macOS-based methods directors, and automation and utility growth.


Expressed ‘tickle,’ software command language (TCL) is among the many extra mature of the programming languages ​​and was born out of frustration, in accordance to its creator, John Ousterhout, due to practices by builders embedding their very own languages ​​into purposes. Having gained worldwide acceptance, Tcl is nothing to chuckle at with its goal of being a general-purpose language that’s as highly effective as it’s easy. What makes it nice is its native extensibility with C / C ++, Java, and Python, its pace and energy to create something from scripted purposes to GUIs, and embedding its code into C-based apps. In phrases of flexibility, extension packages can present extra performance, akin to hooking into libraries that manage an OS’s theme, User Datagram Protocol sockets help, and OpenSSL for securing connections, simply to identify a number of.

That stated, you is perhaps asking your self why it’s possible you’ll not have heard of Tcl earlier than. Well, it’s estimated that Tcl has a couple of 0.1% utilization price throughout all of the web sites worldwide. With such restricted implementation, why decide this language over a competitor that is extra fashionable? There’s a solution for that, too: Cisco, that is why. As a network administrator, you have little doubt no less than heard of Cisco and likelihood is that you simply labored on their tools, or they might be companions together with your group, offering networking tools. Cisco’s IOS (Internetwork Operating System), or the OS used on a lot of Cisco’s switches and routers, has Tcl baked into it and makes use of it to program and automate modifications to its tools en masse. Cisco supplies in depth configuration guides that doc the method of managing their wares via Tcl.

Roles are finest suited to Tcl use are software program engineer, developer, automation developer, methods integration, and prototype / {hardware} architect.


Created in 2007 by Google programmers annoyed with the constraints of generally used languages, the trio determined to construct upon Go, as they are known as it, by sharing the strengths of different languages ​​however not one of the criticisms of C ++, Python, or JavaScript. Two years later, it was introduced to the general public. And whereas Go is a relative newcomer in contrast with the opposite languages ​​listed right here, even you probably have not heard of it earlier than, you’re little doubt aware of what it may possibly do with purposes and providers having been constructed partially, or utterly, primarily based on its code: Docker, Kubernetes, Cloud Flare, Google, Netflix, and Uber is among the main providers powered by Go.

With Go, the educational curve is decrease than, say C, for instance, and the language is extra forgiving, given its light-weight, usability-focused method to coding. Better nonetheless, it was designed with multiprocessing, networking, and for dealing with high-volume information in thoughts. This makes it supreme for not solely dashing up your network administration duties but in addition modernizing it, counting on in-depth libraries and neighborhood help to create platform-independent purposes, comparable to Java.

Roles finest suited to Go used are methods administration, DevOps, software program engineer, information heart engineer.


Again, Python finds itself on prime because the language’s open-source construction lends itself to being supported by nearly all of the working methods. Combined with its comparatively low studying curve, sturdy help neighborhood, and interoperability with many aspects of data expertise, likelihood is nice that studying Python will assist nearly any admin transition from one position to one other without even having to go away the console.

While Python is often used for automating system administration duties, by design, it may be leveraged via using plug-ins and scripts to combine properly into a wide range of workflows, whether or not they give attention to coding, administration, or administration. Additionally, Python can make the most of the present libraries to additional improve the performance of scripts you design or to reduce growth time down considerably.

Roles finest suited to Python programmers embrace penetration testers, safety directors, net builders, DevOps groups, and automation builders.
