DevOps is the change in IT culture. It focuses on rapid IT service delivery through the adoption of agile and lean practices in the context of a system-oriented approach according to Gartner. An amalgamation of two words, ‘development’ and ‘operations’ it aims at combining software development and software operations. It breaks the barrier between development and operation teams. The collaborative work between them leads to the benefit of combined skill.
The concept of DevOps started with the incubation of the first computer program code, written using Fortran in the year 1957. This created one of the first ‘developer’ jobs. In 1967, with the launch of ARPANET, (the network that became the basis for the Internet) a network of engineering jobs and network operations centers were created. Fast forward to 2003, Google hires Ben Treynor to lead the first set of “site reliability engineers” to run a production environment that was separate from the development environment. The team was responsible for maintaining a high uptime (99.97%) while working with the developers to ensure that operations ran smoothly for their customers. Just a few years down the lane, in 2009 Flickr combines “Dev” and “Ops” in an attempt to solve the ‘finger pointing’ problem between the developers and the operations team. Enter John Allspaw and Paul Hammond with the methodology for deploying ‘devs’ and ‘ops’ (DevOps) in cooperation, publically for the first time. The solution was proposed at an O’Reilly Velocity Conference where the two suggested integrating development and operations into an automated infrastructure.
In 2009 again, a Belgium based engineer named Patrick Debois organises a small conference on “agile system administration”. As a mean to advertise for his conference on Twitter, he created a shortened hashtag “DevOps” from development and operations, thus giving birth to the term “DevOps”. Today, DevOps Day is a global movement where developers and operations professionals from across the world get together to discuss about automation, testing, security and organizational culture to avoid the friction between dev and ops.
Fast forward to today – as artificial intelligence permeates almost each and every aspect of our lives, we can witness signs of DevOps further evolving and maturing with the mantra to “automate, automate and automate”.
