What is DevOps?
It is a combination of the English terms development and operations.
Definition
DevOps is a software development philosophy that focuses on communication, collaboration, and integration between software developers and IT operations professionals.
Origin
The term DevOps was coined in 2009 with the presentation "10 deploys per day" by John Allspaw and Paul Hammond at the O'Reilly Velocity 09 event, but the movement actually began in 2007 when Patrick Debois, an independent consultant, experienced conflicts between development and operations teams.
Evolution
DevOps has evolved to include practices like continuous delivery and continuous deployment, aiming to improve the quality, speed, and profitability of software.
Cross-functional Collaboration
DevOps requires a cultural shift towards collaboration and integration between traditionally isolated development and operations teams.
Continuous Integration
Continuous Integration (CI) is a key practice in DevOps involving automatic updates of code in a shared repository. Its goal is to quickly detect and fix errors, improve software quality, and accelerate delivery time.
Continuous Deployment
Another evolution of the DevOps paradigm is Continuous Deployment (CD), where code changes are automatically released into the production environment.
