Which is the best coaching center for DevOps in Bangalore Marathahalli?

 

In the life of every decent successful project, there comes a moment when the number of servers begins to increase rapidly. Devops Training in Bangalore the server with the application ceases to cope with the load and you have to put into operation several more servers and put a balancer in front of them. The database, which previously lived quietly on the server with the application, has grown and needs not just a separate machine, but also another one for reliability and greater speed. The internal team of theorists suddenly heard about microservices and now instead of the problem of a single monolith, many micro-problems appear.

If a couple of years ago, several system administrators who skillfully knew bash scripts and manually configured glands could handle all this growth in infrastructure. Devops training in marathahalli now, to curb hundreds of cars, you need to hire a couple of these guys every week. Or look for alternative solutions. All these problems are far from new - skillful system administrators pulled up their programming knowledge in time and automated everything to the maximum, on a hike giving the world such tools as,

Moreover, programmers, who are still poorly aware of what is happening with their applications after the deployment, persistently continue to consider system administrators guilty of the fact that the new version of the software has eaten the entire CPU and opened the doors for wide open hackers in the world. “My code is perfect, it’s a hell of a shit on your server,” they said. In such a difficult situation, engineers and sympathizers had to engage in educational activities. And what can be educational activities without a buzzword? So DevOps appeared - a marketing term that causes people to have completely different associations, from “culture within the organization” to “jack of all trades”.

Initially, DevOps had nothing to do with a specific position in the organization. Many still claim that DevOps is a culture, not a profession, according to which communication between developers and system administrators should be established as closely as possible. The developer should have an idea of   the infrastructure and be able to understand why a new feature working on a laptop suddenly put half of the data center. Devops Training in Bangalore such knowledge helps to avoid conflicts: a programmer who is aware of how the server works will never put the blame on the system administrator. Also in the scope of DevOps include topics such as Continuous Integration, Continuous Delivery, etc. We once talked a bit about CI in the article Continuous Integration, Jenkins and Middleman .

Naturally, DevOps moved from the category of “culture” and “ideology” to the category of “profession”. The growth of vacancies with this word inside is growing rapidly. But what do recruiters and companies expect from a DevOps engineer? Often, a mixture of such skills as system administration, programming, the use of cloud technologies and automation of large infrastructure is expected from him. This means that you need not only to be a good programmer, but also ideally versed in how networks, operating systems, virtualization work, how to ensure security and fault tolerance, as well as several dozen different technologies, from basic and time-tested things like iptables and SELinux and ending with the more recent and fashionable previously mentioned technologies like Chef, Puppet or even Ansible.

Here an attentive reader-programmer will say:

It is foolish to expect that a programmer who already has so many tasks for the project will also study tons of new things related to the infrastructure and architecture of the system as a whole. Another attentive sysadmin reader will say: We will say this: a real engineer should not be able to Ruby, Go, Bash or “configure the network”, but be able to build complex, beautiful, automated and secure systems, and understand how they work from the lowest level up to the generation and delivery of HTML pages to the browser.

 

                        

Of course, we partially agree that you cannot be an absolute professional in all areas of IT at any given time. But DevOps is not only about people who know how to do everything well. It’s also about maximizing the elimination of illiteracy on both sides of the barricades (actually being one team), whether you are tired of manual work as a system administrator or a developer praying on AWS. In this series of articles, we will step by step get acquainted with the basic tools and technologies of the modern DevOps engineer. A developer who wants to learn a little more about what happens with his code after the deployment, gets acquainted with the necessary details and gets a general understanding of the entire ecosystem, thereby ceasing to be just a Ruby / Scala / Go developer with Ansible skills.

Young (and not young) minds who want to do DevOps will get an idea of   how everything works and the necessary instructions for further study, and then they will learn how to support two dozen organizations at once with one left and make developers and system administrators friendly. System administrators who are bored at their work will learn a few new tools that will allow them to remain in demand by professionals in the age of cloud technology and the absolute automation of infrastructure of any size. Defining DevOps is very complicated, so you have to re-start the discussion about it every time. Only on Habr a thousand publications on this subject. But if you read this, you probably know what DevOps is. Because I do not. and we'll just talk about DevOps and I will share my experience.

I thought for a long time how to make my story useful, so there will be many questions here - those that I ask myself and those that I ask the clients of our company. By answering these questions, understanding is getting better. I will tell you why DevOps is needed from my point of view, what it is, again, from my point of view, and how to understand that you are moving to DevOps again from my point of view. The last item will be through questions. By answering them yourself, you can understand if your company is moving towards DevOps or if there are problems in something.

At that moment, a vision became available to me how the idea of DevOps was being transformed in different-sized companies. After that, it became interesting for me to look at DevOps from the point of view of the market, and my colleagues and I organized the company Express. See how this happens, draw conclusions, analyze, tell our findings to everyone, teach people DevOps practices. In general, in every way we grow experience and expertise. Devops is fashionable. But as Tim Park claims, DevOps is the new standard in development. Given that the infrastructure of modern systems is so complex that people can not cope with its support. Everything needs to be automated.
