CI/CD refers to Continuous Integration and Continuous Deployment, a set of practices aimed at automating the software development process. This skill encompasses the integration of code changes into a shared repository and the automated deployment of applications to production environments. Knowledge of CI/CD is used to enhance software quality and accelerate release cycles by enabling frequent updates, reducing manual errors, and facilitating collaboration among development teams.

Containerization refers to the method of packaging software applications and their dependencies into isolated units called containers. This skill encompasses the understanding of container orchestration, deployment, and management, which enables consistent application performance across various computing environments. Knowledge of Containerization is used to streamline development processes, enhance scalability, and improve resource utilization by allowing applications to run reliably regardless of the underlying infrastructure.

Continuous Delivery is a software development process that involves the continuous and automatic delivery of software updates to customers. It requires specialized skills such as strong automation skills, knowledge of Continuous Integration, and the ability to manage complex software systems. The process allows for faster and more frequent releases with higher quality and reliability.

Infrastructure as Code (IaC) refers to the practice of managing and provisioning computing infrastructure through machine-readable definition files, rather than physical hardware configuration or interactive configuration tools. This skill encompasses the use of code to automate the setup, configuration, and management of servers, networks, and other infrastructure components. Knowledge of Infrastructure as Code (IaC) is used to enhance consistency, reduce errors, and improve deployment speed by enabling version control and automated testing of infrastructure changes.

Terraform is an open-source infrastructure automation tool that provides a simple, declarative language for creating and managing infrastructure as code. It allows users to define infrastructure in versions, manage complex deployments, and automate the configuration of infrastructure resources across multiple platforms such as AWS, Azure, and Google Cloud. Terraform helps organizations create, update, and maintain infrastructure resources efficiently and reliably, ensuring consistency over time.
