DevOps Engineering Jobs and Career Opputunities:-
Engineering is a trending course from past few years ove the world. Every year there are many engineering graduates coming out from each part of country . Be it Chennai Or Kashmir, from north to south. Process of manufacturing engineers is continuing at a fast increasing rate. But jobs in engineering are very less. There is a strong need of quality engineers.For an IT job, there is fight from all section of Engineering. Be it computer engineer, civil engineer or electronic engineer. If you go for online job search, latest job trend is DevOps. DevOps is an abbreviation for its two words. Dev implies to development and Ops stand for operation. DevOps offers various types of job opportunities for you, like engineering project manager, development engineering manager, automation engineers and many more various types of best jobs. Let’s have a closer look at how DevOps is a better career choice for you:
DevOps is awesome if you love to explore and play with variety of Technology and processes. In my opinion the first thing to consider is the Packaging of IT that the tech teams used to provide the organisations services. The maleable the packaging the easier it is to keep everything standardized and reusable. If you are are comfortable working with configuration management systems and developing some imaging systems such as docker you will like DevOps. Closer look to the recent trends tells us the amount of new technologies that are being released into the market is growing exponentially. In DevOps no technology is beyond limits and you find yourself constantly working with integrated and automating different Technologies. In DevOps your goal is to create machines as machine manageable data objects that are completely completely hands off on the production. The goal is to to allow programs written by different teams to efficiently automate as much as possible.
You will definitely like DevOps if reusability is your passion. In my opinion the biggest factor in the successful tech organisations of the future will be their ability to scale rapidly while being able to deflate when not needed to minimise costs in downtime.
If the Application is reliable ,zippy and meet their needs, customers don’t care about the tech behind it. They simply want speed.
Scalability is a hard thing to achieve and most would rather not have to worry about it, which is self explanatory about the growth scalability as a service offering.
Now, Ask yourself. Do you want to jump from mobile to AI? DevOps will allow you. Do you want to play with that new SaaS service that is in trend these days? DevOps will let you do that.
DevOps is all about being the glue that holds everything and everyone together, and if you ask me, that is what makes it so exciting. The possibilities are beyond limits and the technologies are always growing and evolving at an unexplanatory and unimaginable speed. And if you don’t focus on DevOps, you will still somehow have to manage infrastructure as a developer.
Q. What is the need for DevOps?
As per me, this answer should start by explaining the general market trend. Instead of releasing big sets of features, companies see if small features can be transported to their customers via a series of release trains. This is very much advantageous like quick feedback from customers, better software quality, etc. which in turn takes the company to high customer satisfaction. To achieve this, companies are required to:
Increase frequency of deployment
Lower the New releases failure rate
Shorten their lead time between fixes
DevOps lets you achieve seamless software delivery and fulfills all above requirements. You can give examples of companies like Amazon, Etsy, and Google who have welcomed DevOps to achieve levels of performance that were unimaginable even five years ago.
Q. Explain your understanding and expertise on both the software development side and the technical operations side of an organization you’ve worked for in the past.
DevOps engineers always work in a 24*7 critical business online environment. In my previous job, I was very much adaptable to on-call duties and was able to take up real-time, live-system responsibilities. I was successful in automated processes to support continuous software deployments. I have pretty good experiences with public as well as private clouds, DevOps tools like CHEF or PUPPET, scripting and automation with languages like PYTHON and PHP, and a background in AGILE
Q. What is Git?
I will suggest that you attempt this question by first explaining about the architecture of Git.
Git is a form of Distributed Version Control system (DVCS). It lets you track changes to a file and allows you to revert to any specific change.
Its distributed architecture makes it more advantageous over other Version Control Systems (VCS) like SVN. Another major advantage of Git is that it does not rely on a central server to store all the versions of a project’s files. Instead of that, every developer gets “clones” the copy of a repository. “Local repository” has the full history of the project on its hard drive so that when there is a problem like a server outage, you need your teammate’s local Git repository for recovery.
There is a central cloud repository as well where developers can commit changes and share it with other teammates where all collaborators are committing changes “Remote repository”
Q. In Git how do you revert a commit that has already been pushed and made public?
There are two possible answers to the above question so make sure that you include both because any of the below options can be used depending on the situation’s demand:
Remove the bad file in a new commit and push the file to the remote repository. This is the most common and natural way to fix a bug or an error. Once you have included necessary changes to the file, commit it to the remote repository. For that purpose I will use the command
git commit -m “commit message”
Now, Create a new commit that will undo all the changes that were made in the bad Commit. To do so I will be using the command
git revert <name of bad commit>
Q. How is DevOps different from Agile / SDLC?
I would suggest you go through the below explanation:
Agile is a set of values and principles about how to develop a software. For an instance: if you have some idea about something and you want to turn that idea into a working software the Agile values and principles can be used as a way to do that. But, that software might only be working on a developer’s laptop or within a test environment. You need a way to easily, quickly and repeatably move that software into production infrastructure, in a simple and safe way. To do that DevOps tools and techniques are required.
In a nutshell, Agile software development methodology keeps its focus on the development of software but, on the other hand, DevOps is responsible for development as well as the deployment of the software in the safest and reliable possible way.
Now remember, keep this thing in mind, you have included DevOps tools in the previous answer so be prepared to answer some questions related to that. They might be thrown at you.Who is the target audience?
- Who wants to learn Docker Technologies
- The one should have IT experience. No other prerequisite.
