Continuous Integration (CI) is the practice of frequently integrating code changes into a shared
repository. Each change is automatically tested to ensure that new code does not break the
existing codebase.
Continuous Deployment (CD) is an extension of Continuous Integration, where code changes
are automatically deployed to testing or production environments without manual intervention
after passing the build and test stages.
Azure Pipelines is a service in Azure DevOps that allows developers to build, test, and deploy
code. It supports both Continuous Integration (CI) and Continuous Deployment (CD) pipelines,
enabling automation of build and release processes across multiple platforms.
Azure Boards is a project management tool in Azure DevOps that helps teams plan, track, and
manage work. It includes features like work items, backlogs, dashboards, and Kanban boards,

from hardware failures. Each fault domain has independent power, cooling, and networking,
ensuring that failures in one domain do not impact resources in others.
VNet (Virtual Network) is a fundamental component in Microsoft Azure that allows you to
securely connect Azure resources to each other, the internet, or on-premises networks. It
enables network isolation, segmentation, and customization by defining IP address ranges,
subnets, and access controls for connected resources.
