What Is DevOps and How Does It Work?

The term DevOps was first being thought of by Patrick Debois. So, what is DevOps? There was a time when Andrew organized a conference, and Patrick was the lone person to register his attendance. However, many great experts, in collaboration with Patrick Debois, finally gave shape to what we know as DevOps. Patrick worked as a developer, system administrator, network engineer, quality assurance engineer, project manager, and tester. And while working, he realized that in the software development cycle, we are in a position to link each phase with IT operations/deployment. And that meant linking development and IT operations together is possible. Or in other words, it's the communication, association, and integration between the development team and the operations team. You can now realize how Patrick was able to come up with DevOps. And that was because he worked at each of the posts during his working career. That is why we know him as the father of DevOps. DevOps has an 11-year long history, and we highly encourage you to read through the history of DevOps through its Wikipedia page for a better understanding.

How Does DevOps Work?

Have you heard of some great people saying, we always look backward rather than always look only forward, and that is why they can plan their life in a better manner as they learn from the mistakes they commit? The software development lifecycle that DevOps follows are Agile and the Lean software development life cycle. And the new ideas are nothing else but an attempt to correct the mistakes committed previously. The development team corrects those errors or add something new. And the operations team does the deployment. However, now, through DevOps, the development and the deployment are being done in parallel and at the same time. Hence, now a software company or an individual can come up with new versions within a few seconds and instantly. For a better insight, you need to learn the tools like Jenkins and tools like Ansible, and many more, which in parallel get this automation done. The code tools, build tools, network management tools, test automation tools work together through the CI/CD pipeline creation tools like Jenkins to let this automation happen. And these tools stack together with operations tools is what we know as DevOps, and now it is made to work automatically. The monitoring of the whole process is, however, done by the DevOps Engineer. And having the DevOps certification can help you earn the job as a DevOps engineer.

DevOps Roles

There are 7 DevOps roles related to the DevOps. They are:

• The software developer/tester
• The experience assurance (XA) professional
• The release manager
• The security engineers
• The DevOps evangelist
• The automation architects
• The utility technology player

A perfect DevOps Engineer can manage all these processes. Though all of these now exist independently as well due to technology improvement in DevOps.

DevOps supporting cloud services

We have the DevOps AWS and the DevOps Azure, and both AWS and the Azure have the set of services for supporting the DevOps.

DevOps tools

Let's have a list of various DevOps tools.

Infrastructure as Code

It is the management of the infrastructures like VMS, networks, load balancers, and connection topologies through versioning used for the source code. And infrastructure as a code plays a significant role in DevOps technology. And more elaborately the IT Operations or the infrastructures need to be treated as the code for the implementation of the DevOps. The developer is the application, and the infrastructure is the IT Operations. Tools used for IT Operations are Dockers, Kubernetes, configuration management tools like Chef, Ansible and Puppet, Splunk and Nagios.

Hardware requirement:

The infrastructure used is a prerequisite for the DevOps engineer. And a DevOps must know in detail the VMs and the containers as well as other hardware used.

Apart from these, all the DevOps methodologies require functionalities such asautomation, continuous integration of builds, deployment, code management, and operations like containerization, configuration management, and monitoring to be precise. As a DevOps engineer, you should know one tool from each of the above functionalities. And the best DevOps Engineer knows all the tools from all the above functionalities. For configuration management, we have tools like the Ansible, Puppet, and Chef. For the development of the CI/CD pipelines, we have tools like Jenkins, and for the container technologies, we have the Vagrant, Kubernetes, and the Docker. There is Nagios ELK, Splunk, and Zabbix for logging and monitoring. And these all forms the DevOps models.

The DevOps Engineer must know scripting languages like Java, Perl, and Python. And they must, to some extent, need to understand how to automate things as well. Like YAML scripting language, the Python is being used by the Ansible for automation.

Various advantages of the DevOps are:

• Continuous deployment
• Continuous integration
• Continuous delivery

And you can now figure out what advantages you are going to have through the DevOps.
