What is mean by the DevOps – A Brief Introduction Guide

What is the DevOps?

 
The DevOps can be explained as a process. It is very effective way for the developing as well as deploying. Also, for the testing as well as operating with very high quality.
 

The DevOps History:

 
Before DevOps, all the industries had separately two teams. They are as follows.
 

  • Development.
  • Operations.

Development Team:

 
They work in the software. They generally develop the software. Also, make sure whether all the codes work perfectly. After very hard work & after many times of trail and many trails, they release the code. This is possible after operation team execute these data.
 

Operations Team:

 
They will check the app and how it works. Also, they will report back to the developing team if they find any bugs.
 
These two teams always have conflict when the code comes for execution. Both the team should use the same processor, OS, memory and scripting language. Else the code won’t work. The reason beyond this is, if these environment changes, they may miss some library files.
 
Operation team will always treat the code as faulty. This is even the problem is with the system. This leads to throwing back the code to development team. This may build a gap between both the team. In order to avoid this gap both the team are collaborate with each other. This leads to the growth of the DevOps.
 

What is mean by the DevOps and its working?

 
The DevOps is generally not the tool / team. This is generally a process / method. This is possible by using many tools. It is for solving any issues between both the team. So, we called it as DevOps.
 
DevOps helps us integrate all the functions of the software development. Especially within same cycle. This is from the development to the operations. This must need a high-level coordination. Especially within various teams in the project. Following are the team which includes in this. They are,
 
• Development Team.
• Quality Team.
• Operation Team.
 
The DevOps helps us to break the barrier for delivering the code. Especially in the short time. There are generally 4 basic processes. They are,
 
• Continuous Integration.
• Continuous Delivery.
• Continuous Testing.
• Continuous Monitoring.
 
Let’s see in detail.
 
Continuous Integration:
 
In short, we can call it as CI. It is a process which is continuous. This process will combine the source code which we get from various sources. Especially in one app. Then it will run the automated set of the test cases. This is on resultant app.
 
Continuous Delivery:
 
In short, we can call it as CD. It is a process which is continuous. We can test the app. So that the code is ready for delivery as a product. We can generally say this as an extended process of the CD. This involves enough testing as well as delivery as a product.
 
Continuous Testing:
 
This is a continuous process. We can validate the app whether it is build based on the requirements. The functions as well as the performants meet it.
 
Continuous Monitoring:
 
This is a continuous process. We can monitor as well as conform whether the app works as per design. Especially in the particular environment. We are having many tools for monitoring app’s performances & issues. We may require a team for collaborating with the developers. This is for building their self-monitoring system.
 
DevOps usually follows an approach. This will put a great effect development as well as testing automation. Generally, DevOps works with the following manner. They are,
 
• The developers team start writing the codes.
• Prepare the QA environment.
• Executing the test cases.
• Deploying the production environment.
 

Needs of the DevOps:

 
Most of us may know about the Agile. There are some minor differences in the Agile & DevOps. Most of the people who work in Agile can easily adopt to DevOps. When we apply the principle of the Agile in development & QA. The output from the operation side is different. So, we need DevOps for rectifying this gap.
 
DevOps bring us with the new term called as CD. Using this we can write as well as commit. Also, we can deploy, test & install the production environment. These are ready for end users. The allover process helps the team develop & deliver the very high standard code. We should automate every code in DevOps just for working properly. It also reduces the time of delivering the codes.
 
In working with Agile, constant changes is embrace. But in the DevOps, it is test & delivery. Similarly, in agile we embed customers. But in the DevOps, it is Operations. Generally, we can say that DevOps is the extended concept of the Agile.
 

Responsibilities as well as Job Openings:

 
In the above sessions we discuss about the concepts of DevOps. Also, the needs of the DevOps. Now in this session we will discuss about the job openings in this field.
 
While surfing in linked in we can find that there are 4000 and more jobs available for the DevOps engineers. This is only in India. Also, it keeps on increasing day by day. Many top MNC’s likes to hire DevOps experts.
One of the highest paid job is DevOps engineers. A well experienced engineer in DevOps may get almost $117,000 per annum. This pay scale is only in India. A well sound DevOps may get the range between 12 lakhs to 18 lakhs per annum.
 
Following are some new roles in the DevOps. They are,
• Consultant.
• Developer.
• Test Analyst.
• Architect.
• Manager.
 
DevOps embedded two main fields of the institutions together. This is mainly for solving many problems which IT industries faces day to day. This ideology leads a great growing carrier opening.
 
Now I hope you will understand the basic concept of DevOps. Also, why we need it. This article will definitely boost your interest against this domain. For getting more knowledge you can also enroll with us. We provide you the world’s class training in DevOps with field experts.
