DevOps is a software development approach that combines and automates the work of software development and IT operations teams to accelerate delivery of secure, high-performance applications.
Traditionally, development and IT operations practiced separately from each other in distinct silos. DevOps outlines a development process and an organizational culture shift that fosters coordination and collaboration between these two functions, with a shared set of tools and practices. It automates an agile development cycle in which small chunks of new code are added to the code base at frequently intervals (usually at least once per day) and then integrated, tested, and deployed to production.

Infrastructure as code (IaC) is a DevOps practice that automates the provisioning and management of IT infrastructure by using configuration files rather than manual processes
Microservices is a cloud-native architectural approach in which a single application is composed of many loosely coupled and independently deployable smaller services. Experts describe microservices as optimized for DevOps methodology and dependent on DevOps for success.
Containers are executable units of software that package application code along with its libraries and dependencies, allowing code to run on traditional IT or cloud infrastructure.
Container orchestration automatically provisions, deploys, scales and manages the lifecycle of containerized applications. Developers use container orchestration to streamline agile or DevOps workflows. Today, Kubernetes is the most popular container orchestration platform.
Observability is the ability to understand the internal state or condition of a complex system based on knowledge of its outputs. It plays a crucial role in maintaining the availability, performance and security of modern software applications and systems.
