What is all the Hype about DevOps?

DevOps is the latest buzzword in the world of software development. So what really is DevOps? DevOps can mean a ton of different things to different people. This is because the term is rather broad and covers a lot of ground. DevOps is mentioned in terms of ‘treating code as an infrastructure’, or ‘collaboration of operations and development’ or ‘using automation’ or treating it like a ‘culture’ or a variety of such related phrases and terms. Much like terms like ‘Agile’ or ‘Quality’, DevOps is a concept that covers several aspects of development and one would require some nuance in order to completely understand what it is. Let us touch upon some history of where the DevOps originated from in order to get a better understanding.


Where it all began


Agile software development evolved into DevOps. It has its origins in the need to match increasing software velocity and throughput that agile methods achieved. The need for a more holistic approach to the end to end software delivery lifecycle was felt with the advancements in agile methods over the years. The ideals of DevOps over take agile in terms of development practices with extended streamlining of the movement of software change all through code, test, deploy and delivery stages. This is done while enabling cross-functional teams that have complete ownership of software applications, right from design to production support.


DevOps is also defined as a mindset that encourages collaboration, communication, integration and automation among software developers and IT operations teams so as to improve the quality and speed of delivering software. Here is how DevOps achieves what it promises:


  • DevOps teams stress on standardizing automating delivery processes and development environments in order to improve delivery predictability, maintainability, efficiency and security.
  • DevOps principles give developers a lot more control of the production environment. This gives them a good understanding of the production infrastructure.
  • DevOps greatly empowers teams with the power of autonomy to do the entire build, validate, deliver and support their own applications.


A deeper understanding

Here is a mapping of the DevOps method of work

  • DevOps Principles: Agile’s principles pauses at code checking but with DevOps, the principle stretches to include operations and systems. It is basically, infrastructure as code.
  • DevOps Values: DevOps focuses on delivering an overall service including complete software to the customer instead of just a ‘working software’. The values is better understood when you add developer and operations collaboration to Agile’s values.
  • DevOps Methods: Here you can make use of Scrum + operations or Kanban + operations etc. There is also use of incident command system for incident response.
  • DevOps Tools: There are a number of DevOps tools that have been released –
  1. Travis, teamcity, Jenkins etc.
  2. Configuration management tools like Chef, puppet.
  3. Orchestration tools like Mesos
  4. Monitoring, containerization and virtulization tools like Vagrant, AWS, Docker and many more!

A lot of tools do not by themselves bring you DevOps but its more about how its used in collaboration with other tools. There are certain specific tools being developed at the moment with the intention of facilitating DevOps principles, practices and methods.

  • DevOps Practices: There are specific techniques that are used in order to implement the processes and concepts discussed above. The mantra is continuous integration and continuous deployment. Use of configuration management, monitoring schemes and metrics and a tooling with a toolchain approach along with using even cloud computing to accelerate change.

DevOps is certainly going to turn into the norm. Stay tuned to know how! IIHT offers courses that include DevOps where industry experts train students with real life like projects. Get in touch to know more!
