Chapter 1: Introduction to DevOps

Software Development and IT Operations teams' tasks are combined and automated via DevOps, which accelerates the delivery of higher-quality software. By automating and combining the work of the development and IT operations teams—two groups that had previously operated independently or in silos—DevOps, by definition, describes a software development process and an organizational culture shift that accelerates the delivery of higher quality software.

The best DevOps practices go beyond development and operations to include platform and infrastructure engineering, security, compliance, governance, risk management, line-of-business, end users, and customers, among other application stakeholders, in the software development lifecycle.

The term DevOps refers to the current state of software delivery cycle evolution over the past twenty-plus years, from large-scale application-wide code releases every few months or even years to iterative releases of minor features or functional upgrades on a daily or multiple times daily basis.

In the end, DevOps is about satisfying the always growing needs of software users for regular, creative new features as well as continuous availability and performance.

1.1.  An Overview of DevOps

The acronym DevOps, which stands for "Development and Operations," refers to a collection of procedures, tenets, and cultural ideologies that are intended to enhance and simplify the cooperation between teams working on Software Development (Dev) and IT Operations (Ops). Increasing the effectiveness, dependability, and speed of software development and delivery is the aim of DevOps.

Among the crucial elements of DevOps are:

Collaboration: By fostering communication and cooperation between development and operations teams, DevOps dismantles the conventional silos. This partnership facilitates quicker development and deployment cycles and aids in the more effective resolution of problems.

Automation: A key component of DevOps is automation. Code testing, integration, and deployment are examples of repetitive procedures that can be automated to help teams save time, assure consistency across environments, and lower manual errors.

Continuous Integration (CI): CI is the process of consistently combining code modifications from several authors into a single repository. Every time a code change is committed, automated builds and tests are started, which aids in finding and fixing problems early in the development cycle.

Continuous Deployment (CD): After the required tests are completed, CD deploys code changes to production environments automatically, expanding the capabilities of Continuous Integration (CI). As a result, releases become more regular and dependable, which shortens the time it takes to provide end customers with upgrades and new
