What is DevOps?

DevOps a combination of development and operations is an agile relationship between developers and the operations teams to improve the quality and increase the speed of software delivery by removing the hurdles of communication, cooperation, and different processes in the software development life cycle.

DevOps came up in the industry of software development and operations during 2009. The entry of DevOps started to emphasize integration between developers and people working in operations preventing the two teams from contradictions. DevOps proves the interdependence of development and operations thereby improving the productivity of the organization.


Improved service excellence
The service excellence mainly depends on the amount of services available without error as well as ability to re-establish the services away from the error. Because of the high-speed feedback loops and high-speed performance, the errors that occur during the service period are removed quickly leading to service excellence.

Consistent service distribution
In DevOps, the projects are fragmented into mini projects which can be delivered one after another continuously. As a result, the changes for the mini projects are possible any time. Hence with quick healing dependable service delivery is achieved.

Highlights more customer value being open to their feedback
With newer technology in the market, demands of the customers are rapidly increasing. And to stay applicable, businesses should adopt themselves to the changing environment. With shorter projects, shorter release cycles and shorter improvements in the fragmented projects, DevOps helps in improving the value of your products or demands of your services. With frequent feedbacks, DevOps allow you to design the product according to the demands in the market, instead of completing the entire project and then again work to make changes based on the demands arising in the market.

Augmented user gratification through better usability
With smaller release cycles in DevOps, the customers can pass frequent feedbacks on the timely updates they get. Because of which you can test your product and modify it to reach their satisfaction. You can also add different features to different forms of your product depending on your customers. This will help you to satisfy different groups of users with the same product with different features by A/B testing.

More efficiency in operations
Since release cycles are minimum, hence there is very less unnecessary waiting time which helps agility and in imposing relevant prices on the products.

Diminishes bottlenecks between the two teams
Earlier there were more bottlenecks between the development and the operations team while working together. But with DevOps, their boundary line became blur and as a result both the team members learn from each other and realise each other’s work processes. As a result, the ops member can figure out and modify the code without waiting for the developer.

Amend collaboration among employees
DevOps has brought both the development and operations team to work together, because of which, a lot of collaborations among both the team occurs. Because of emails, scrum meetings the employees gel together resulting in positive attitude among each other.

DevOps Tools

There are tools and technologies that support automation and collaboration between the development and the operations team

  • Jenkins
  • SolarWinds Log & Event Manager
  • Vagrant
  • PagerDuty
  • Prometheus
  • Ganglia
  • Snort
  • Splunk
  • Nagios
  • Chef
  • Sumo Logic
  • RabbitMQ
  • Logstash
  • Loggly
  • Apache ActiveMQ

Why DevOps?

There are three primary practice areas that are usually discussed in context of DevOps.

  • Infrastructure Automation – create your systems, OS configs, and app deployments as code.
  • Continuous Delivery – build, test, deploy your apps in a fast and automated manner.
  • Site Reliability Engineering – operate your systems; monitoring and orchestration, sure, but also designing for operability in the first place.

DevOps Values

  • DevOps Culture
  • Communication & Collaboration
  • Trust
  • Decreasing Silos
  • Fast Feedback loops
  • Systems thinking
  • Lean
  • Automation
  • Measurement
  • Continuous Improvement

DevOps Principles

DevOps value is derived in the core principles that started the movement

  • Iterative
  • Incremental
  • Continuous
  • Automated
  • Self-service
  • Collaborative
  • Holistic

Agile-Inspired DevOps Methodologies

DevOps need persistence and development of Agile approaches and observes being tracked to the development and operations teams to accomplish infrastructure provisioning and robotics, unceasing specialist care and provision requests in construction setting. The exercise syndicates development and operations — from the design and development stages of the Agile SDLC to construction sustenance in IT operations.

DevOps Practices

Some of the DevOps practices include

  • Self-service arrangement
  • Production support
  • Continuous build
  • Continuous integration
  • Continuous delivery
  • Robotic release organization
  • Automated testing

Goal of DevOps

The main goal of DevOps is to advance partnership between all participants from preparation through distribution and automation of the distribution process, to:

  • Progress in the deployment regularity
  • Accomplish quicker time to market
  • Lesser disappointment rate of new issues
  • Abbreviate lead time between solutions
  • Recover mean time to repossession

How to implement DevOps?

The main approach to DevOps is CAMS coined by Damon Edwards and John Philips in Silicon Valley back in the 90s and early 2000s. CAMS define the culture of responsiveness.

CAMS to Continuous Delivery

The CAMS approach helps the DevOps team to achieve continuous delivery.

  • They admire the CULTURE by admiring each other
  • They AUTOMATE anywhere probable to remove error
  • They MEASURE evolution, and
  • They SHARE reaction without restrictions

DevOps Implementation Using CAMS Approach


The CAMS attitude is not a trick that many companies drop into by pleasing discrete accomplishments at the cost of the entire team. Instead of two goals, one for development and one for operations, there is an amalgamated goal line of swiftly installing code carefully and consistently. Attaining this needs a swing in culture, which needs a swing in team assembly and development.


Automation of code deployment is a must right from development through testing to production so that the right ones get repeated and the wrong ones are fixed. The develop, deploy and test processes are repeatable only if they are automated. Manual practices are prone to more errors.


Rework is always a tough work. For proper feedback, correct tracking and monitoring is required which comes from measurement. Mistakes are expected, but they should not be repeated. Measurement is like aligning bonuses to employees in a team. When bonuses for different employees in a team work against each other, it all ends up with team frustration leading to a lose-lose situation. So, to achieve a win-win situation, proper equilibrium is needed which comes from accurate measurement.


To share problems, people need a blame-free environment. Because, people hide problems, when they are in a punishable environment. Environment should be blame-free. Because punishment doesn’t make anyone make fewer mistakes. People always make mistakes. Hence, instead of fixing people, we fix machines. Hence giving a blameless post mortem. This mortem gives opportunity to each team member to weigh in on what went wrong. It helps in focusing the problem, instead of claiming immunity.
