Role and Responsibilities of a DevOps Engineer - Kovair Blog

DevOps is the fusion of social thinking approach, practices, and apparatuses that builds an association’s capacity to deliver products and service at high pace: developing and adapting products at a quicker speed than businesses utilising customary software development and infrastructure management procedures. This speed empowers companies to give their customers comprehensive services and stay ahead of their contemporaries. DevOps is the posterity of agile software development – conceived from the need to stay inline with augmented programming speed, and throughput agile strategies have accomplished. Development in agile culture and approaches over the past few years revealed the requirement for a more universal approach for the end-to-end software delivery lifecycle.

Who is a DevOps Engineer?

DevOps Engineer Starter Guide – Stackify

DevOps Engineer is a professional who comprehends the Software Development Lifecycle and has the inside and out knowledge of different automation technologies for creating advanced pipelines (like CI/CD). DevOps Engineers works with designers and the IT team to manage the code discharges. They are either designer who gets inspired by deployment and network operations or system admins who have an interest in scripting and coding and move into the development side where they can planning of testing and deployment.

In DevOps, there is a need to have a continuous and gradual change in the code so that testing and deployment are conceivable. It probably won’t be persistently feasible for DevOps Engineers to do the coding from the start again and again; in that case, they need to know about it. There is a need for DevOps Engineers to associate different components of coding alongside libraries and programming advancement packs and incorporate different parts of SQL data management or various messaging tools for running programming release and deployments with OS and the production foundation. This article walks you through the skills required to be a DevOps Engineer:

3. CI/CD (Continuous Integration/Continuous Delivery)

Continuous integration vs. continuous delivery vs. continuous deployment

Information on different automation tools isn’t sufficient as you should also know where to utilize these. These automation tools ought to be utilized so as to encourage Continuous Integration and Continuous Delivery. Continuous integration and Continuous Delivery are the procedures where your development squad includes constant code changes that are pushed in the principle branch while guaranteeing that it doesn’t affect any progressions made by designers working parallelly.

4. Software Security

Secure Software Development: Step-by-Step Guide

DevSecOps (Security DevOps) has emerged as one of the tech buzzwords in the previous year for a reason being that DevOps helps in creating and deploying programs way more quickly, it likewise makes a lot of vulnerabilities, since security groups can’t stay aware of the quicker cycle. Basically, not just excellent code but bugs and malware can also be sent a lot quicker at this point. Presenting DevOps without having culminated security forms in the IT-association is a catastrophe waiting to happen. Accordingly, DevOps ought to have the fundamental programming security aptitudes to have the option to bring security into the SDLC directly off the bat.

 5. Efficient Testing Skills

15 Must Have Skills For a Top Automation Tester

DevOps is gigantically affected by how well testing is done in a tech-based company. You can’t robotize the DevOps pipeline if effective constant testing, the procedure of executing automatic tests, isn’t set up. Continuous testing ensures that each computerized trial gets executed the way it should, or there is a huge risk of pushing faulty code straight away to clients, which isn’t acceptable.

 6. Soft Skills

DevOps professionals come from a multitude of IT backgrounds and begin the role in different places in their careers. Generally, the role of a DevOps engineer is not as easy as it appears. It requires looking into seamless integration among the teams, successfully and continuously deploying the code. The DevOps approach to software development requires recurring, incremental changes, and DevOps Engineers seldom code from scratch. However, they must understand the fundamentals of software development languages and be thorough with the development tools utilized to make a new code or update the existing one.

A DevOps Engineer works alongside the development team to handle the coding and scripting expected to associate the components of the code, for example, SDKs or libraries and coordinate different parts, for example, informing tools or SQL DBMS that is required to run the product discharge with OSs and generation framework. They ought to be able to deal with the IT framework as per the sustained software code devoted to multi-tenant or hybrid cloud environments. There’s a need to have a provision for required assets and for obtaining the suitable organisation model, approving the launch and checking execution.

The Abysmal Developer

I’m not sure if there are any real metrics to judge the quality of software developers thus no one knows how good they really are. The thing that comes closest to rating a software developer is the feedback from their peers – what do they think about their programming abilities? Generally software organizations don’t invest in a 360 degree feedback thus most of us are always clueless about how good we really are. There is a lot of literature on how to become a better or great developer but there is hardly anything out there to identify a lousy developer. This is an attempt to share some of the top-notch qualities of a lousy developer. Well, think of it as an “Good Developer Anti-Pattern”.

Mistakes I've made as a junior developer — and how you can avoid them. | by Jack Finlay | We've moved to freeCodeCamp.org/news | Medium

Writes code that only machine can understand. The lousy developers take great pride in writing complex code. There would be no separation of concerns, everything would be one giant ball of spaghetti code, the methods would as long as the Great Wall of China, the variable names would be unintuitive as if an obfuscator had named them.

Never keeps the team informed about milestones. Who gives a shyte!? I ain’t telling nobody about the daily progress. Yes, you would hardly get to know what they are working on until you prod them. Asking status from them becomes such a chore that you shudder at the very thought of it.

Needs to be Micro Managed. They need constant baby sitting from their team mates or their manager about tasks they are working on. They just can’t work independently. Period. You give them their own space and you know things would never get done on time. They would constantly forget their tasks or would deliver code in a haste without giving too much thought to it. To them, bugs or unfinished tasks are the hallmark of a working developer. Yeah, right!

Not a Team Player. Their world is finite and they are at the center of their own little universe. They won’t acknowledge the skills of other team members and think they are the best thing after sliced bread.

Blame Game. Somehow it is never their fault when things go wrong. It’s like the word sorry is not in their vernacular. They always have something or someone to blame when things go wrong rather than admitting to the mistake.

Wastes too much time. Most of them are always busy doing other important things than programming like chatting with their friends, spending time on facebook etc. I just don’t get it. Why would anyone spend killing their office hours than being productive or learning new technologies/reading technical blogs.

The thing is that it only takes a mental switch to turn off these nasty habits and adopt more productive ones provided one is willing to make oneself better.

The Good Developer

There are various parameters to judge a developer but for me the number one criteria is efficiency. Ahem…I don’t mean efficiency of writing bad code or providing sub optimal solutions. Far from it.I mean the efficiency to write good code. Readable Code. Extremely Flexible Code. A highly maintainable code.It’s the efficiency with which they passionately latch on problems and solve them. They are efficient because they understand the underpinnings of the programming framework and the toolset they use every day. So, how does one become efficient at developing software or be “The Good Developer”?

What Makes a Good Developer? A Manager's POV. | by Distillery Tech | Medium

I’m not sure if you loved Physics or if you ever understood Einstein’s famous mass-energy equivalence. Well, the one where he proved that mass of a body is a measure of its energy and they are connected by a constant.


    • =


I hope Einstein forgives me for this. But, in our little software development world, it means


    • = Efficiency


    • = (intrinsically) motivated


    = Cluefulness

Thus, efficiency of a developer can be defined as their level of motivation to excel times the square of their cluefulness.

True. Seriously. Don’t believe me? Ask Einstein. Can you? You can’t, can you? Then, you really have to trust me on it ?

What is Cluefulness? It can be defined as one’s expertise and capabilities in developing software. Please read this extremely insightful post by Eric Sink if you want to learn about Cluefulness and how to increase it.

If you one of the developers who are extrinsically motivated by rewards, all-the-things-money-can-buy-kind-of-salary, free beer to write code – tough luck in this life. On the other hand, if you are intrinsically motivated to learn new frameworks, delve into complexities of algorithms and data structures, write code for fun then all you have to worry about it is how to increase your cluefulness.

I won’t repeat what Eric mentioned in his great post but I would mention few things to increase your cluefulness.

Read Code – It’s surprising how less time developers really spend reading other people’s code for learning patterns and anti-patterns. Some developers would keep on writing the code in same style that they learned in school. For real. One can either learn by working with really good developers or reading code of open source frameworks/products. I can’t emphasize enough the value of reading code – Can one become really good writer if they haven’t ever read a good book in their life?

Focus – How can one become good at their art if the first thing they were to do every morning was check their friend stream on Facebook, chat with their long lost friends on their favorite IM, check their emails, any-other-unproductive-activity-except-programming. Shouldn’t the first thing really be to focus on building great software? I doubt if Einstein would have come up with general theory of relativity if he was checking his friend feed on facebook all the time or was being bugged by other Physicists on Skype.

The Best Software Development Tools Of 2021

Be Inquisitive – One has to be curious and hungry to learn new things, ruminate on hard problems, figure out ways of doing old things in a new way. One would never learn better ways of doing things if one is happy with the status quo.

Tools are your best friend – I’m not sure if a developer could really be productive in writing ASP.NET applications using Notepad. One has to be good at Visual Studio.NET or an equivalent IDE to be really productive at building websites using the ASP.NET framework. Thus, it’s not only enough that one spends the time in learning and polishing their programming skills but also picking up tricks to use the development environment to their advantage. Learn the Shortcuts, write loads of reusable code snippets, know how to use Nuget etc. They are an aide to being efficient and solving problems faster.
