What is DevOps in 2021 | benefits of DevOps | importance of DevOps

What is develops? 

So if you talk about devolved, there are a lot of different ways to define DevOps. You can't define it one way or the other. But, some definitions tell you that DevOps is this and this. But it's like a nebulous cloud where you have a certain idea of what it is, but you can't always put it into words. 

But if you really had to put it into words, you could say that it's a mix of a way of software development where there is a certain set of principles and values you have to follow in DevOps, to get the better software development process. Or you could say it's only a set of values and principles. 

Or you could say, it's a set of tools. Or you could say it's a way to automate things. It's a lot of these different things. Instead of thinking of all of these different definitions as single definitions for DevOps. 

What you can do is you can just think of them altogether. It is over your software development. It is, developing software with a set of values and principles instilled in the people who are working in software development. 

And it is a methodology and there are tools that you use in DevOps and you do automate the whole software development process. So all of these different things combined to tell us what DevOps is. 

What is the meaning of DevOps?

Now the name DevOps comes from developer and operations. So DevOps bridges the communication gap between the software developers and the I.T operations team. 

So you have the developers who developed the code that's their sole job and you have the I.T. Operation scene, they manage the whole infrastructure on which the whole software is being developed and they're the ones responsible for making sure that the software is given to the end-user. 

So what a DevOps person does is basically bridges the gap between being a developer and being an operations person. So that's how the name comes in the death from developers and the ops from operations.

What exactly DevOps is

DevOps is a set of practices that combines software development and I.T. Operations. It aims to shorten the system development lifecycle and provide continents delivery with high software quality. Now devotes is complementary with agile software development. Several developed aspects came from agile methodology.

Importance of DevOps

DevOps is important because it's a powerful tool for continuous delivery, speeding up development time, and making your IT organization more efficient. DevOps is also extremely easy to set up.

DevOps principles have now gained a lot of currency in the operations industry. We have seen a lot of enterprises adopting DevOps methods and practices in the past few years.

It is quite evident that implementing DevOps practices helps to enhance the agility of businesses and is better for the overall efficiency of businesses. Moreover, DevOps can bring about a radical change in IT departments and is capable of improving and enhancing the culture and practices in companies

So what are the benefits of DevOps? 

So some of the benefits are - 

Having high productivity now on implementing diverse, you're definitely going to see a very high increase in the amount of productivity you have because a lot of processes that were originally being handled by humans are now being, automated, they're being scripted now. And that definitely increases the productivity you have. Other people can then go ahead and concentrate on the thing that they have to solely concentrate on. 

A developer doesn't have to worry about ops things. And he definitely only has to worry about writing the code and then pushing the code and then waiting for it to be deployed to get feedback, make the changes and then, you know, repeat the cycle. That's his job. So that way productivity definitely increases.

Excellence

You get an excellent product in the end or a service in the end, whatever you're providing to your user, you provide the best particular product slash service there is in the market because you're improving equality. After all, you're improving your productivity and hence you're improving your quality also. 

And there are a lot of certain aspects that we will talk about that help us to improve the quality of our product with, you know, continents testing, whether it be dynamic testing or started testing then returns. 

Returns

So when I talk about returns, I'm trying to say the profits or the revenue that the organization will generate will increase because of the other two factors -

1. Because of high productivity. 

2. Because of excellent product

you will definitely see a rise in the returns or the ROI, the return of investment, the revenue that the company generates or, the profit they're generating.

And a lot of other benefits of Deops are, 

Having a speedy and rapid delivery

You're able to, deliver the software that you want very fast because you're automating a lot of the processes. So you can deliver the software you want very fast.

Robust security

So when you talk about development, you also have to consider the security aspect. There is a specific field in DevOps called Segue DevOps. Which concentrates only on the security aspects. They try to make sure that the whole software development pipeline is very secure. There are no security vulnerabilities whether it be in the networking, whether it be in the software code itself.

You know, it makes sure that the software code you have is as secure as possible because the software is the company's asset, it's the product. So you have to make sure that nobody steals it or makes it or misuses it. 

It helps you to check everything that is being done by any person who has an interaction with the software. So that creates a layer of security. That definitely helps you protect your software.

Better scaling

To explain better scaling let me tell you guys about, what happens when a small company grows into a big one. You have a small, you know, start-up And they have a really great idea. They want to expand even further. They have only 10 people working for them, but they can deliver some, product, in the end, they're able to, put bandages, cracks that they see and, give the product as they can.

It's not the perfect software, but then, it's giving them the things that they require, that users that they require. Now nor they decided to expand their whole organization because they're generating revenue. They have they want to expand. So what happens in that scenario? Well in that scenario, this started will face a lot of problems. 

They will have to rewrite a lot of the old code because the old code is, it's banded cool, because, they're just writing whatever they can to make whatever software there is because the number of resources they used to have wasn't enough. But now that the company is expanding, they have enough resources that they have to work, really work a lot of the things. 

So in that matter, the scaling is not happening perfectly. So that's why you have to keep scaling in mind when you as a startup also. So, DevOps, if you implement DevOps from the start itself, you can see the benefits of it by having better scaling the whole software development pipeline can be scaled accordingly. 

You can have multiple sets of different teams working on the same infrastructure because you're able to scale it very well. So that's again a very important benefit of DevOps. So these are the different benefits that Devil's provides on implementation. 

DevOps phases

So DevOps has certain phases inside of it.

1. Continuously development

So in incontinence development, you're developing code for the software continuously, incontinence testing your testing that code continuously.

2. Continuous integration

In Continuous integration, you're connecting all the different parts of the software development process, that is the development process, that you're testing process, that is the deployment process, or that is a modern process. It connects all of them together. So that's what happens in continuous integration and it does so continuously.

3. Continuous deployment

You're basically deploying the software continuously, continuous deployment is a software release process that aims to continuously integrate new code, test, and deploy in as close to real-time as possible. To accomplish this, a CI/CD pipeline is used to run code through continuous integration and test

4. Continues monitoring 

Where the one you're, you're monitoring the deployed software, you're making sure whatever happening, whatever happens in the software is being monitored. If some crash happens, if there is a bug then you need to know about it so that you can make sure that the coder rectifies that mistake later on in the next cycle. 

So you can see the trend over here. There are continents in all of these phases. Now, continents make sense because what DevOps tries to implement is automation and you know continents integration and delivery of everything.

To do that, they make sure that every person just does what they're defined to do. And it instills a mindset in the developers and everyone else who is working in this whole pipeline that they have one goal that is to deliver software. 

So that's where we have continuous development, content testing integration, and deployment countries monitoring it keeps on happening continuously and everyone has one mindset and they're instilling them that they have to just, deliver the software, that's their job.

• FAQ for DevOps

Q1. What is a DevOps example?

Developing code for the software continuously, incontinence testing your testing that code continuously.

Q2. Why DevOps?

DevOps is important because it's a software development and deployment paradigm that blends elements from two previously separate and incompatible cultures.
