What is DevOps?

DevOps is the practice of Operations and Development teams working side-by-side during the software delivery lifecycle, from design, testing, deployment and production monitoring.

Introduction

DevOps is the combination of Software Development and Information Technology Operations. It’s also one of the most buzzed about trends in the industry.

In fact, the Puppet 2017 State of DevOps survey showed DevOps has increased by 11 percent since 2014. Additionally, high performing organizations that followed DevOps reported deploying 46 times more frequently, recovering 96 times faster, and have a change failure rate that is 5 times lower than low performers.

But what is DevOps, where did it come from, and what makes a successful DevOps team? In this guide, we’ll walk you through the history of DevOps through its present-day use, and explain why it has become such a popular approach to software development.

The Old Way Of Software Development


Responsibilities Of Development

  • Programming new features
  • Prototyping
  • Developing
  • Debugging
  • Designing software
  • Writing code
  • System improvements
  • Data analysis and research
  • Documentation

Responsibilities of Operations

  • Keeps software fully functional
  • Ensures quality, consistency, reliability, operability, and availability
  • IT security
  • Monitoring performance and issues
  • Application support and troubleshooting
  • Server and device management
  • Database maintenance for enforcing longevity and durability

Traditionally, many people followed the idea that development and operations had conflicting priorities and responsibilities, so by default they were put into isolated roles.

Since developers were working on building new features and changing code, they inherently opposed Operations’ job of maintaining stable software.

The problem with this train of thought was that, although the Development and Operations have different functions, they were still all working toward the same goal of producing bug-free, quality software that serves the customer.

DevOps

As the software delivery lifecycle matured, one thing became apparent. While Operations wanted software to be dependable, they also wanted to contribute to new features and innovate technology. And while Development wanted to build new functionality, they also wanted it to be delivered as a secure and reliable product.

A main goal of DevOps was to recognize this and make it easier for the two departments to work together to meet these goals, and integrate their skills throughout the SDLC.

DevOps is largely a culture shift to bridge the divide between development and operations.

It aims to join two siloed roles into one department where both sides of development and operations are necessary to deliver effective software to the customer, and asks for both positions to learn Development and Operations while specializing in their individual roles.

 

 

 

 

 

 

DevOps and Agile


Ultimately, DevOps is an approach to Agile development. It focuses on every member in the software development life cycle collaborating to ensure software is released quickly without impacting quality.

This include development and operations, of course, as well as quality assurance, testers, business owners, clients, and project managers.


A Little More About Agile

With Agile, teams are getting software ready for release through development and always keep it completely functional so it can be delivered at any time.

Additionally, Agile specifically emphasizes a more collaborative relationship between departments so that teams could respond effectively to feedback and change, while releasing new features, functionalities, and improvements regularly.

Like we mentioned, the creation of the term DevOps is a reaction to the shift to Agile development. Because of the disconnect and isolation of teams prior to the DevOps movement, these goals were much harder to accomplish.

“Since the Agile methodology was only implemented during the development phase, the operations departments was left behind, leading to deployments piling up faster than it was possible to release them.”

As organizations adopted Agile mentality, conjoining teams under DevOps was common sense to improve cross-departmental.

Conclusion

As organizations transition to Agile and test automation, and recognize the positive impact of breaking down departmental silos, many will adopt and follow DevOps.

While DevOps is not a singular role or job, it is a culture shift that aims to unite everyone in software development to work towards a common goal, most likely delivering stable, high performance software.

It includes fast feedback, frequent changes and updates, and communication from all parties throughout the software development lifecycle.

“Having a team that thinks through all the aspects of building and delivering software as well as how code, environments, tools, business rules etc. all play together to solve a problem is why DevOps became a positive trend.” -Yaniv Yehuda
