Understand DevOps as a Service

Blog Post created by Vishal Denge Employee on Dec 15, 2017

“ According to the latest DevOps report, DevOps has increase 200 times more frequent development, 24 times faster recovery from failures, 3 times lower change failure rate, 50% less time less security issues. ”


If you want to find a definition of DevOps, you will find number of definition on Google search, I think DevOps can be explain simply as DevOps that integrate development and operational team in order to improve Collaborations, Culture, Automation and Productivity by automating the entire infrastructure, automating workflow using Continuous Integration and Continuous Delivery and by measuring the application performance with repeatable customer feedback.

Before DevOps (Evolution)

DevOps arises from existing software development methodologies over the years in response to business needs, to understand DevOps first up of all we need to see the evolution of software development. Before DevOps we had waterfall model for software development. This development consists of different stages like Requirement Gathering, Architectural Design, Coding, Testing, Quality Assurance and Maintenance, after that software was delivered in the market. All of these stages works differently, due to this everything was manual. Some days after people found that this model is very slow and it take a long time to develop and deploy the software as everything was manual from testing to releasing.

and if in this duration the requirement of customer change, then this model fails to satisfy changing customer requirement. Due to such limitations of water fall model people started using agile development. The difference in agile is that the entire software is not delivered in one cycle. It breaks down the software in smaller piece of feature and delivered it over the time.

Using this feature customer get more satisfaction with the development and allows the developer to be flexible with the requirements which changes as per the users need. From the feedback by the customers.


Agile model lack agility in operation, and testing was also manual with no interaction between developers and operational teams, that’s when DevOps arrives. It is the approach of making integration in both development and operation. Number of companies are now moving towards DevOps mindset because they all realize that the software and its services must go hand to hand to get full proof software to market.

Why DevOps?

To understand DevOps in more details let’s take an example, Consider of a company, in which there is developer and operational team. Developer team is responsible for developing code which involves a developer, tester, etc. in Development Environment. Operational team is responsible for quality assurance, build, test, deploy and release the software which involves system admin, manager, etc. in Production Environment.

Developer team is mainly focused on writing code for its Development Environment where it’s not identical to the Production Environment.

Now suppose operational team finds out that there is some change needed in given software or service, operational team then contact with developer team and informs them that "there is change needed in given software", but developer team says, "no we have checked it several times, this software is working properly". Due this conflict occurred in between developer team and operational team. In that time faulty software gets released in the market and reach up to the end user. End user then experience errors or bugs in the software. Due to this they directly blame to that company which produced that software.


Things happen because there is no interaction between developer team and operational team. Which leads to slow development, slow release, reducing market values, etc.

So, What if developer team and operational team work together and shared their responsibility. Ultimately, they want the same thing i. e. customer satisfaction.

What is DevOps?

DevOps is mindset in which developers and operations teams work together in order to improve collaboration and productivity, by automating infrastructure, workflows and continuously measuring application performance. If operational team and developer team were more DevOps oriented, they would have done few things differently. They focus more on automation. DevOps team try to automate everything, from testing of new code to releasing it, and also monitoring it.


The other component to the formula is getting the right tools.


Store different version of code.


Test code and programs & Continuous integration,


Manage and document all the changes to their Application Code and their Configuration Management Code.


Build code and its dependency in one container.

Chef, puppet and Ansible

Deploy applications in an automated fashion, maybe across hundreds or thousands of servers.

Nagios & New Relic

Continuously measure & monitor the performance of their environment, they will also need a tools for application monitoring, to monitor application performance.

Marathon (DC/OS)

Container orchestration framework provided by the DC/OS Mesosphere platform for deploying and running the application container.


In Conclusion part of it, DevOps is Mindset that can help software organizations innovate faster and be more responsive to business needs. It promotes collaboration between developers and operations, which improves the quality of software deployments.


Hopefully this information will enable you to getting started with DevOps. Stay tuned for next update.
