The term DevOps has gotten a lot of hype, especially among large nerds in their first or second semester who wish to pursue DevOps as a career. Is it, therefore, the best option for you? First and foremost, what exactly is DevOps? There are many resources available out there. However, none of them provide a clear picture of what DevOps is, how to earn the right certification, and which DevOps books to look out for.
What Is DevOps?
DevOps is not a technology, program, or language that can be learned and used to declare yourself a DevOps engineer.
DevOps is more of a mentality than anything else. DevOps is more of a mindset than it is a procedure. It is how you take your product, app, or whatever website you are developing and make it so that millions of people may use it. This entire process can be done in a multitude of ways.
To define it, DevOps is an integration of cultural philosophies, practices, and devops tools that optimizes a company's ability to deliver applications and services in an efficient and expedited manner: it entails use of traditional software development and infrastructure management processes.
You can learn more in detail about it with DevOps tools training.
How Does the DevOps Approach Work?
When a small-scale application is created, it is simply uploaded to the cloud or programmed, and the features are made available to the entire world the next day.
However, on a bigger scale, these websites or apps are created by various teams that manage various aspects or architectures of the applications, resulting in a midsize application or firm. Typically, there are two teams: one is the devils developers or development team, which encompasses all development regardless of where you work, and the other is the operational team. Occasionally, testers are also included in this group. On the other hand, the operations team has the responsibility of managing all server setup and a few other things.
What if the two departments combined their efforts and collaborated? The DevOps strategy is what it's called. The DevOps symbol looks like an infinity sign, implying that it is a never-ending process of increasing efficiency and activity. The DevOps method allows businesses to respond to upgrades and development changes quickly.
DevOps oversees a simplified flow between the teams and makes the software development process effective, allowing teams to deliver quickly and deployments to be more consistent and fluid.

With the help of many tools, the DevOps culture is implemented in stages.
The development team creates a strategy based on the application and the goals that will be provided to the customer.
When the plan is finalized, the coding begins. Each development team member works on the same code, and different versions of the code are stored in a repository using tools as needed. This is known as version control.
Tools like Maven and Gradle are used in the build stage to make the code executable. After the code has been properly produced, it is tested for any defects or mistakes using selenium, the most widely used tool for automation testing.
The code is now being deployed to the working environment by the operations team. Ansible, Docker, and Kubernetes are the most popular methods for automating these processes. After the product is deployed, it is regularly monitored, and Nagios is one of the most popular tools for automating this process.
The feedback collected at the end of this step is forwarded to the planning phase, which is the heart of the DevOps life cycle. Jenkins is the tool that sends code to be built and tested; if the code passes the tests, it is sent to be deployed, which is known as continuous integration.
Many tech behemoths and enterprises have adopted the DevOps methodology. Learn more about these tools from DevOps best online training.
