Introduction

In the field of Information Technology, DevOps is a day-to-day word. With such huge interest in this field, the requirements for DevOps engineers has also increased. DevOps engineers are one of the most demanding job profiles with no signs of slowdown. Statistically, the demand for DevOps professionals in the employment market has increased by about 35-45% over the last 2 to 3 years, and that number is growing rapidly. DevOps is currently a challenging task that requires a wide range of skills as well as adequate experience and in-depth knowledge in this area. It’s no wonder DevOps is set to dominate the IT world in the future. And if you’re looking forward to your career as a DevOps engineer, then you are on the right track!.

What is DevOps?

Patrick Debois, an independent IT consultant coined the word ‘DevOps’. After that the field hasn’t stopped spreading or evolving. DevOps Engineers bring development and operations together to rapidly accelerate delivery. The demand for DevOps Engineers stemming from the limitations of Agile is slowly becoming a bottleneck in agile delivery. While development teams are rapidly pushing new changes each sprint, operations teams are struggling to maintain application stability and security at such a rapid rate.

Bringing together both developers and operations engineers, DevOps Engineers has bridged the gap between processes. Teams understand each other’s requirements, prepare and plan accordingly. DevOps Engineers uses different tools and processes to enable better collaboration and communication between teams. Infrastructure flexibility is enhanced with continuous monitoring that makes it easier for teams to manage and secure their applications.

What Are the Different Phases of the DevOps Model?

1. Continuous Development

Continuous development, the first phase of the DevOps lifecycle, includes all planning and coding of a software application. At this stage, DevOps Engineers sit down and visualize the results, i.e. what the software application will be. Once the vision is in place, developers start writing and maintaining the code. There are several tools used to maintain the code. This process is called source code management. Some of these tools include SVN, Git, Jira and CVS.

2. Continuous Integration

The phase of Continuous Development is followed by the phase of Continuous Integration, and the first phase naturally transforms into the second. This phase consists of several processes, including the preparation of test execution to be carried out during the testing phase, as well as comprehending the project requirements supplied by the customer in order to add the essential features into the software product. The stage also includes frequent updates to the source code, generally on a daily or weekly basis. The Continuous Integration stage is sometimes referred to as the “heart” of the broader DevOps lifecycle since it is the step in which errors in the code may be spotted early on.

3. Continuous Testing

The Continual Testing step entails testing the created code on a continuous basis to check for bugs, errors, and weaknesses. This is also the phase in which the program’s usability is tested using a set of best practices for QA, and it is assessed whether the product fits the client’s criteria. Continuous testing is accomplished through the use of automated testing technologies, which can be open source tools like Selenium or complex test management platforms like QARA Enterprise and TestNG. These technologies enable the DevOps Engineer of QA team to run several tests concurrently in order to maximize test coverage and testing efficiency.

4. Continuous Deployment

The fourth step of the DevOps lifecycle is Continuous Deployment, which entails delivering code in such a way that it does not impair the performance of the product or website. During this step, it is critical to ensure that the code is correctly distributed on all servers. It is all about ensuring that the product is deployed with the highest precision and with no room for error.

5. Continuous Monitoring

Monitoring is the fifth step of the DevOps lifecycle, and it entails capturing and analyzing vital information about the application in order to determine places where more work is necessary, as well as general trends. This is an operational phase, and the goal is to improve the operational efficiency of the software programme while also regularly monitoring its performance.

Top Skills and Tips on becoming a DevOps Engineer

The following section will talk about top 8 essential skills to have in order to become a perfect DevOps Engineer.

Communication and Collaboration

Given the fundamental nature of DevOps, communication and cooperation are critical to success for DevOps Engineers. These two are critical in breaking down silos between Dev and Ops teams, aligning team goals with business objectives, and implementing DevOps culture cross-functionally.

Soft Skills

If you’re only strong at code and automation, it won’t cut it. DevOps requires a new kind of person, one with soft skills, self-motivation, flexibility, and a willingness to learn. DevOps Engineers should be both doers and listeners.

They must understand that DevOps transformation entails stakeholder dialogues, understanding of company goals, assessment, and identification of areas for improvement, all of which are fueled by cooperation.

Usage of Tools

The success of DevOps is solely dependent on the toolset used throughout various stages of implementation. It’s difficult to keep track of how many tools DevOps has introduced. However, the importance of DevOps success is something that should be examined in depth.

Security Management

In many cases, the pace of risk matches the pace that DevOps enables delivery. Due to this limitation, the security of the usual method may not work in the end or as a separate process. This is where DevSecOps is great at building security on SDLC from the beginning.

Therefore, DevSecOps skills will definitely help you succeed as a DevOps Engineer.

Automation Skills

To be referred to as a DevOps engineer, you must have a strong understanding of automation, which is at the heart of the DevOps process. A DevOps engineer should be able to automate the full DevOps pipeline, which includes CI/CD cycles, app performance monitoring, infrastructure and settings, and so on.

The capacity to know about DevOps toolset, coding, and scripting is tightly tied to DevOps automation expertise.

Coding and Scripting

Two critical skill sets for a DevOps engineer to have are coding and scripting.
Python, Ruby, Java, Javascript, PHP, Bash, Shell, and Node are all examples of programming languages. NodeJS is one of the most popular programming and scripting languages.

Testing Skills

The process of Testing is critical to the success of DevOps. Tests that execute without fail will be required in the DevOps automation pipeline.

This is critical for the success of continuous testing, which involves the execution of automated tests.

Cloud Skills

The cloud and DevOps are inextricably linked. The efficiency of one is directly affected and affected by the efficiency of the other. While the DevOps approach drives the process, the cloud drives the process by providing the essential infrastructure for testing, deploying, and releasing code.

The cloud supports DevOps automation by providing the required CI / CD toolset and resource monitoring mechanism.

What do DevOps do in Plan, Build and Deploy phases?

We do different things in every different phase.

In the Planning Phase, a plan for the sort of application that has to be built should be prepared. It’s usually a good idea to get a broad understanding of the development process.

In the Build phase, the application is built using codes from various phases.

In the Deploy Phase, the code is placed in a cloud environment for later use. It is verified that any new alterations do not interfere with the operation of a high-traffic website.

Define Continuous Testing?

Continuous Testing is the execution of automated tests as part of the software delivery pipeline in order to offer immediate feedback on the business risks inherent in the most recent release. Every build is continuously tested in this manner to eliminate difficulties with Software delivery life-cycle and to allow Development teams to receive rapid feedback. This results in a huge gain in developer productivity since it eliminates the need to re-run all tests after each update and project re-building.

What are the three core DevOps KPIs?

The three key performance indicators are as follows:

  • – Meantime to failure recovery – The time it takes to recover from a failure on average.
  • – Deployment frequency – The frequency with which deployments take place.
  • – The percentage of unsuccessful deployments represents the number of times the deployment fails.
