How Learning DevOps benefits to get a lost job in pandemic


Ever since the outbreak of the pandemic, Covid-19 has occurred, it has capsized a lot number of businesses and even has imposed shutdowns. In short, this pandemic has not left any stone unturned if we talk in terms of various spheres of life, but even in this situation, the IT industry has become stronger, and eventually, the demand for DevOps is increasing.

Due to the pandemic, all the working places, be it school, colleges, everything is shut right now, and hence people have gone for an alternative: Online(Internet), and hence online classes, online meetings and working from home has become a new normal over the past few months. One important thing to observe over here is, the digital businesses’ activity was not at all obstructed even due to the arrival of this unfortunate disaster, whereas it has deeply hampered the growth of non-digital businesses and so it has proved that the only means of survival for a business is its capacity to carry out a digital transformation, and this fact has made a lot of such businesses conscious about the importance of

digital transformation and the role of DevOps in that process and hence we can say that DevOps is unstoppable and cannot be hindered by the Coronavirus.

Before we move further, we need to be aware of certain things,


  •  What is DevOps?

It’s a combination of two words, ‘Development’ and ‘Operations’, and is a term for a collection of concepts, using code that helps in production in a catalysedmanner (fast in an automated and repeated manner). It enhances an organization’s speed to carry out applications and services. In simple terms, we can say that DevOps is an association of development (Developer and Testers) and IT operations with finer cooperation and communication. Now, that we know what is DevOps, we stumble upon the next question, why do we need DevOps?

  •  Need for DevOps

There are certain reasons, which tells us, why do we need DevOps course, and they are:

  1. No Proper Synchronisation -> When DevOps was not in thepicture, the development and the operation team used to work in seclusion.
  2. Wastage of time -> As Testing and Deployment didn’t go hand inhand, after the design-build, hence it used to take more time than the real build cycles. Also, for this very reason, team members had to spend more time in these activities rather than concentrating on making the project.
  3. Increased number of errors -> Code was manually deployed,which led to a large number of errors in the production.

As we are aware of the need for DevOps, the next thing that comes into our mind is, how is it different from IT?

  • Difference between DevOps and IT

In the case of IT, new orders are placed for servers, and the Development team works on testing. The Operations team works on extensive written documents as required in enterprises to deploy the base, whereas in the case of DevOps when a new order is placed, the Development and Operations team works simultaneously on the paperwork to frame the new servers.

If we look at it from synchronization’s aspect, then in the case of IT, we see that both the Operations and the Development teams work in an isolated manner, and hence neither of them have a clue regarding the progress of each other’s department, while if we talk about DevOps, both the teams are aware of the progress each of them is making, and together develop a monitoring plan that serves the IT and business needs. They even use advanced Application Performance Monitoring (APM) Tools, which yields better results.

If we talk in terms of announcements, then we see that traditional IT is lacking from DevOps even in this aspect. How?

So, before going live, the performance testing happens to smash the application, which in turn delays the release, but this is not the case with DevOps, because, before the actual release, when the performance testing is done, it makes the application somewhat slow, but the development team soon fix the blockages, resulting in the on-time release of the application!

  •  Usage and adoption of DevOps

DevOps is preferred due to the following reasons:

  1.      It offers a lesser failure rate of the new releases.
  2.      It makes a version of everything, resulting in satisfying the sudden need to restore the previous version.
  3.      It saves time to market, through smooth software delivery.
  4.      In terms of risk management, DevOps applies security to every aspect of the software delivery process, thereby reducing the chances of a defect in the procedure.
  5.      It offers cost productivity in the software development procedure.


Adopting DevOps -> It’s advisable to use it for big distributed applications, like the ones hosted on cloud platforms, like the ones which provide services.

  •  Life-cycle of DevOps

It consists of several procedures, namely DevelopmentIntegration, Testing, Feedback, Deployment, and Monitoring.

  1. Development -> In this stage, the software is in its initial stage,that is, it is in the process of being developed. In this stage, the entire development process is broken into small development fragments. This helps to speed up software development and also the delivery process.
  2. Integration -> In this phase, the source code is revised manytimes(weekly or daily). New codes that support the extra functionalities are integrated with the already existing code.
  3. Testing -> Sometimes, this phase might be carried out beforethe Integration phase and depends from developer to developer. In this phase, the developed software is tested against all possible errors, bugs. A test environment is set up with the help of Docker containers, and automated testing is done, which in turn saves a lot amount of time and effort. Thistesting generates reports which enhance the test assessment process.
  4. Feedback -> This phase may be called an intermediate phasebetween the Integration and Testing phase, where based on reports, the improvements made, are analysed. The customers who tested the application, share their experience, and accordingly, the developers work upon it, to make further improvements, and once there’s a positive response from the customer’s side, it opens the way for the release of new versions of the application.
  5. Deployment -> In this stage, it is ensured that whatever thechanges are made at any time in the code, it won’t affect the working of the heavily trafficked website (more number of people visiting the website at a given time).
  6. Monitoring -> It is the last stage but is of high importance. Inthis particular phase, the operation team takes care of the abnormal system behaviour or any bugs which are found in production.
  •  Principles of DevOps

The following principles are essential when you are adopting DevOps:

  1.      The DevOps should always invest in products and services, the reason being it is client-centric.
  2.      The team needs to provide performance support till the last, as this improves the level of responsibility and the quality of the products pulled off.
  3.      The team should focus and work on continuous improvement to minimize wastage, and as a result, it continuously speeds up the improvement of product or services offered.
  4.      Automation is an extremely vital point of the DevOps process. This not only stands for software development but also for the entire infrastructure.
  5.      In DevOps, everyone’s role is predefined, be it developer, designer, or the tester, but they should work as one team and put their combined efforts into it, which would fetch better results.
  6. DevOps must havesturdy monitoring and testing procedures.

Now, that we know some basics, let’s see how we can get a job in this discipline.

  •  DevOps Engineer

A DevOps Engineer is someone, who is an IT professional, working with software developers, system operators, and other production IT staff to oversee the code releases. They can be either developer who get fascinated in deployment and network operations or system administrators who have a passion for scripting and coding and move into the development side where they can improve the planning of test and deployment.

  •  DevOps Job Roles

An individual may benefits with the following job role after their DevOps online training:

  1. DevOps Evangelist –> The leader who is in charge ofimplementing DevOps. This role is given to someone, who is responsible for making sure that the DevOps strategy isimplemented in the end-to-end development of the product, and brings about a positive difference in the environment. This role also demands that the person should find methods to improve the existing architecture regarding the product.
  2. Release Manager –> Someone who releases new features &ensures post-release product’s durability. Someone, who is in this post, needs to integrate the newly added or updated features with the existing structure. Somebody, who belongs to this post, should arrange and administer the product from development through deployment.
  3. Automation Expert –> This post is for those who are willing tobe responsible for achieving automation & balance of tools. Being in this role, one should be able to understand what can be automated and how a product stack can be fused with another product stack.
  4. Software Developer/Tester -> Someone, who develops the codeand tests it, and hence this is the root level in terms of the development of software. So, the people who belong to this, are not only developers but also testers.
  5. Quality Assurance -> This is a newly added role in the DevOpsculture, and this role assures the quality of the product. This role is also known as Experience Assurance, and not to forget, this role is one step ahead of the traditional testing and quality checking. Someone, who is in this role, always looks for opportunities to enhance any feature to bring client satisfaction.
  6. Security Engineer -> This role is as important as the previousones. This role is responsible for monitoring the deliverability of the product. One thing to note over here is that they work hand in hand with the developers, implanting their suggestions into the process. They even observe the systems, check their performance, report the interruption, if caused, and drill down to explore the cause behind it.
