DevOps Engineer is something big with no dimensions. You will hear many experts saying that you need the knowledge of Linux to become a DevOps Engineer. That is because many consider Linux to be a more intuitive OS for developers than Windows. However, Windows 10 is not bad too. However, OS is just one of the tools that are part of DevOps. We have a lot of DevOps tools, as we discussed in one of the previous blogs. To become a DevOps Engineer, you need to learn these tools in detail. And you need to understand the software development lifecycle. However, remember that Agile is not just a possibility. The DevOps does make use of Scrum and Kanban as well. Hence, we need to know all the software development life cycle apart from the DevOps tools. In this article, we are going to discuss who is a DevOps Engineer. We will discuss their role and responsibilities, various tools, skills, job descriptions, and the DevOps Salary. And if you want to learn DevOps, you can contact Naresh I Technologies. We provide complete DevOps training for all DevOps certifications. Naresh I Technologies also is the number one computer training institute in Hyderabad and among the top five computer training institutes in India.
DevOps Engineer:
In a nutshell, the DevOps Engineer is the one who has complete knowledge of Development and Operations, or he performs a part of it like testing, deploying, code management, building, monitoring, or like that. Hence, he can be everything, or he can be a part of it. And accordingly, we have the responsibilities and the roles for them. He can be a tester, a code release manager, a DevOps Architect, a Security specialist, An Automation Expert, or a Software developer.
What is DevOps?
We have already discussed DevOps. However, let's brief again. It's the junction where the Development and the operations meet and then move together from there.
DevOps tools:
We have a long list of DevOps tools. Like we have operating systems such as Linux, macOS, and Windows. We then have code versioning tools like Git and Mercurial. We also have provisioning and orchestration tools like Chef, Puppet, and Ansible. We have the CI/CD tools like Jenkins and Bamboo. We have monitoring, trending, and alerting tools like Nagios and New Relic. We have containerization tools like Docker and Kubernetes. We have application deployment tools such as Capistrano, web servers, application servers, Queues, caches, and databases. We have logging tools like Splunk, ELK Stack, and Logstash, and process supervisors.
You should know that the tools discussed above can be integrated with cloud technologies and give the best results. You will love to provision and orchestrate the AWS services with the help of Ansible. Hence, DevOps is not all about cloud technologies. It's good without the cloud technologies. However, it has become more than efficient with cloud technologies like AWS DevOps and Azure DevOps. The GCP also has a good DevOps setup. However, AWS holds an edge over the other DevOps setups as it's the oldest. And it is most well-defined.
Who is a DevOps Engineer?
Hence, a DevOps Engineer is the one who knows all of the above tools, or he/she knows a set of tools and is proficient in a task. However, in every role, he will need complete knowledge of a DevOps setup.
He will need to work as a team as DevOps is all about collaboration. And it's a team effort. And since these tools are engineering skills, he is called a DevOps Engineer.
DevOps Job Roles and Responsibilities:
Various DevOps Job Roles are Automation Expert, Security Engineer, Code release manager, Quality Assurance Engineer, DevOps Evangelist, Software developer, or tester. Let's see what each of them has as their role. A Software developer has the coding task. The tester does the manual and automation testing. He writes the test cases and works on the tools like Selenium. The Security Engineer has a look at the security issues, and hence he needs to know the monitoring tools like the Nagios and Logstash. The Automation Engineer needs to create the required Pipelines for automation, which we know as the Continuous Integration/Continuous Delivery tools like Jenkins, and Bamboo, and configuration management tools like Chef, Puppet, and Ansible. The Quality assurance Engineer needs to look at the profitability of the developed software, and based on the feedback, he guides the software developer to write better code.
To summarize, we need to cater to the services based on each stage. Each DevOps engineer performs the DevOps stage-based responsibilities. And we have already discussed that above.
DevOps Engineer Skills – DevOps Job Description:
Various skills are OS like Linux, macOS, and Windows 10, as discussed above. A DevOps Engineer needs proficiency in architecting the complete DevOps setup. He should know all the tools discussed above. And, such kind should be fit for all or in at least one stage of DevOps. A DevOps Engineer can be a fresher, or he can be an experienced candidate. An experienced System administrator can easily become a DevOps expert.
DevOps Engineer Salary:
The salary of a DevOps engineer can be a minimum of $91000. And maximum, there is no limit. The average salary of a DevOps Engineer in the US is around $115000. In India, the "minimum salary" of a DevOps Engineer is around 650000 INR. And a maximum of 1250000 INR. However, with experience, your salary can be any figure. It depends upon your job description.

We cannot consider the DevOps as a process with an edit, and in fact, it is a never-ending process. However, you require the tools for implementing DevOps. In this article, you will find the list of the top 10 DevOps tools of 2021. And you should know these in detail. DevOps is not a tool, and it's a culture that a software development company can leverage for better productivity. It brings the Developer team and the operations team on the same stage, and it caters to work in collaboration and as a team from any location and securely. And the top 10 DevOps tools for 2021 are certainly going to be Git, Selenium, Jenkins, Docker, Check, Puppet, Ansible, Elk Stack, Nagios, and Splunk. And if you want to learn all these, you can contact Naresh I Technologies. We provide complete DevOps training for all DevOps certifications. Naresh I Technologies also is the number one computer training institute in Hyderabad and among the top five computer training institutes in India.
Whenever we think of DevOps, the first tool that comes to our mind is the GIT. Its version control system caters to us the power to track the changes in the file, and it makes it easier to coordinate the work in between the team, and each team member has the newest version of the work. Each team member has one branch, and there is one master branch. The Administrator manages the master branch, and on approval of work, he/she pushes it from the developer branches to the master branch. However, Git has a lot to offer.
Jenkin is the open-source version of the Hudson (acquired by Oracle) and written in Java. You can make use of it for continuous integration and continuous development. It ensures all DevOps stages, which we can integrate with more than 1000 plugins. You can continuously build, test, deploy, and update using Jenkins. You can communicate through CLI, GUI, and Rest API.
Docker happens to be the tool that makes use of the container. It's for packaging the application with all the dependencies and requirements before shipping it as one package. You can make the shipment of it anywhere, may it be QA, to your team, or you can scale the cloud to any number of nodes and ensure almost zero downtime. Kubernetes is another containerization tool that will be trending in 2024.
It's a powerful configuration management automatic tool that can convert the infrastructure into the code for ensuring easy management of data, roles, attributes, environments, and cookbooks via infrastructure as code. You can understand now that CloudFormation of AWS makes use of the Chef. And you can integrate it with any cloud-based platform.
It's the configuration management tool that is open source and applied for automating the inspection method and ensure the delivery and the operation of the software over the entire lifecycle and is not dependent on the platform. It's based on the master-slave architecture and is open source. It has a long commercial track record.
Ansible happens to be the open-source tool used for automating the provisioning and orchestrating of the infrastructure like cloud deployment, network configuration, and creation of development environment. Remember, it's a push-based tool based on master-slave architecture. We write a "Playbook in YAML" for Launching an "EC2 instance" and running a Java-based web application on it. In an environment where we have the GIT, Jenkins, and the development and production environment, we can manage them all through the Ansible playbook.
It's a software platform for searching, analyzing, and visualizing the data and logs generated by the machine and gathered from applications, websites, sensors, and devices that make the IT infrastructure and the businesses. You can make knowledge objects for the operational intelligence and monitor the business metrics for getting the insights from the log files. You can also ingest in various file format data.
Nagios happens to be a monitoring system. It helps you to identify and resolve the problems in IT infrastructure. And it detects before they start affecting the complex business operations. You can monitor through it as well as troubleshoot the server performance-related problems. You can also ensure through infrastructure upgrades that outdated systems do not cause failures. You can also detect and fix the issues automatically.
It's the combo of Elasticsearch, Logstash, and Kibana, and it can help you find out the insights from the log files without actually going through them. Thus, we can catch the intruders through this stack. It's open-source and comes with loads of plugins.
Without any doubt, DevOps is the key for all software development companies in the 21st century, and no such company is going to survive without DevOps like cloud computing.

DevOps is a combination of Development and Operations. It's one of the latest trends in software development, and with it, the developers and operation staff can work together to ensure that the software runs efficiently and there are no errors. Software development teams are now using DevOps. It helps them to cope up with the market pressure. And they can deliver the software in less time. Thus, they are earning more profit. And if you want to learn DevOps, you can contact Naresh I Technologies. We provide complete DevOps training for all DevOps certifications. Naresh I Technologies also is the number one computer training institute in Hyderabad and among the top five computer training institutes in India.
You can consider it as the development and the operations working together and is a concept which deals with various things like software development, services, and the Operation. Three essential things are collaboration, communication, and integration between the IT operations personnel and the software developers. The recent past has certified the importance of the DevOps certification.
The requirements of the developers are continuous change, and they always want to add new features.
The Ops, on the other hand, want to ensure stability all the time, and they always look to come up with new services.
Have you seen head and tail fighting? It's a fight that is always won by anyone. However, have you seenHead and Tail together? DevOps is something like that. It's head and tail on the same side of the coin. The development team always wants to update the production environment with the changes it commits, and the operations team wants stability and the least changes. However, the dilemma is both of these are important.
And on many occasions, the development and operations come in conflict with each other while delivering value. The operations tea wants to ensure that the production system does not change so often though the development team keeps asking for the change. And hence there is a gap in between the development and the operations which occurs at various levels.
Incentives gap: development and the operations team have different goals.
The Process gap: There is a different approach between the development and the operations for managing the changes. That needs to be in the productions, and there is a need to maintain it as well.
The Tool gap: The development and the operations make use of their tools for doing their work. And hence there is a gap in between the tools used by the two sides.
The result of this is that the development and the operations work like silos, and both are different teams.
The main reason for the conflict between the development and the operations is that the development team wants continuous change, and the operations team always fear making the changes.
The DevOps binds the "software development" and the "operation team" It reduces the gap between agile software development and operations. And all DevOps experts do possess the knowledge of all business matters.
The DevOps happens to be a culture and not just a methodology or the framework. You can consider it a set of principles for breaking down the silos. You can use it if you think of collaboration, measurement, automation, and establishing a culture.
When we talk about culture, we talk about the people and the process. If you don't possess a culture, the automation will never work. There should be a relationship, and only then automation is possible. And DevOps make that possible. You can kill the silos, engage often and early. You will have options and never get a chance to blame any team member as all leverages the correct picture of the "software development" and "IT operations" work all the time. You can communicate with peers, ask questions, scale to any level, do almost anything, and ensure the best security.
There are various automation tools for DevOps, though you need to establish the culture. We have tools for provisioning, configuration management, release management, monitor and control, and orchestration.
If you have the same thing to do, again and again, you need automation.
Automation is efficient as well as saves a lot of time.
It saves a lot of "manpower," and hence the money as well.
You can automate the builds, testing, deployment, early fault detection and rectification, system upgrades, and system configuration.
Measurement is a necessity for improvement. And a successful DevOps implementation helps you to measure all it can and also regularly.
The performance, process, and all metrics can be the basis of measurement via the DevOps.
You thus improve over-time via capacity planning, fault detection, and trend analysis.
Sharing can solve the problem, and with a good team, you can solve any problem, but you need to share. And you can share your ideas, metrics, technology-related details, code, instructions, test cases, and almost anything.
"Patrick Debois" a Software Development Consultant, researched all aspects of IT. He worked as a developer, network specialist, system administrator, tester, and project manager. Amid, Patrick got a consulting job. And there, he has to deal with the data center migration. He looked after the testing job, which meant he spent a lot of time in "Development" and "Operations" However, the conflict between the development and the operations bothered him. And he got frustrated while facing the challenges of work management amid this data center migration.
Continuous integration got recognition from the agile community. And, it became quite close to the development. However, still, the conflict between development and operations was there. Though Patrick believed that there is a way to make these two teams work together. And it was his effort plus some others like Andrew Shafer and John Allspaw and a few more that made the DevOps a reality. Agile development methodologies play an important role in DevOps. We recommend you to have a read about the complete evolutionary history of DevOps.
The DevOps Lifecycle is on Agile methodologies. It comprises continuous development, builds, test, deployment, and update stages, and the process repeats with an update. The update is a change from the developer. Or It can be a request from the test team for correcting the code. Or it can be like an infrastructure upgrade and much more. However, all you can summarize with code, build, test, deploy, and update stages.
There are various technical benefits like continuous delivery, less complexity, early fault detection, rectification, and zero downtime.
There are various business benefits like faster delivery, better stability, and time-saving ensuring more profit.
We have operating systems, and all are covered. Azure and AWS (and various others) ensure infrastructure is available as service. We have virtualization platforms like VMware, Vagrant, and VirtualBox. We have the containerization tools such as the LXC, docker, and Kubernetes, configuration management tools like Puppet, Ansible, Chef test, and build systems like Jenkins, Maven, and Ant, Application deployment tools like Capistrano, Web servers, application servers, Queues, caches, databases, Monitoring, alerting, and trending tools like Nagios, New Relic, and Logging tools like Logstash and Splunk and process supervisors.
