What is DevOps?

DevOps is a set of practices, tools, and cultural philosophies that automate and integrate the processes between software development and IT teams. It aims to shorten the system development life cycle and provide continuous delivery with high software quality. DevOps achieves this by fostering a culture of collaboration and communication across developers, operations staff, and sometimes beyond, into areas such as security (leading to the related term “DevSecOps”), to ensure rapid, reliable, and responsible software delivery. Key aspects of DevOps include:

1. Continuous Integration (CI): A practice that involves regularly integrating code changes into a shared repository, where automated builds and tests are run. This helps in identifying and fixing integration errors quickly, improving quality, and reducing the time to release new software updates or features.

2. Continuous Delivery (CD): An extension of continuous integration, aiming at ensuring that the software can be reliably released at any time. It involves automating the release process so that software can be deployed to production at any moment, manually or automatically, ensuring the software is always in a deployable state.

3. Infrastructure as Code (IaC): This is the management of infrastructure (networks, virtual machines, load balancers, and connection topology) in a descriptive model, using the same versioning as DevOps team uses for source code. Like the code that provides the business logic of your app, your infrastructure code should be kept in a version control system and integrated into the CI/
