DevOps - A set of practices that combine IT and Software Engineering practices that assist in reducing the time
required to reliably engineer and deploy code to production environments.
Version Control - The process of tracking and managing the incremental changes of source code and configuration files,
usually handled with various tools and utilities.
Continuous Integration (CI) - The practice of merging the distributed copies of a development team’s codebase into a
centralized repository, usually several times a day.
Continuous Delivery (CD) - The cycle of creating, building, testing and manually releasing software at a high
frequency and with consistency.
Continuous Deployment (also CD) - Almost identical to the Continuous Delivery process but with automated releases
instead of manual releases.
Infrastructure - A collection of logically architected systems and network resources that act as the communication
backbone between users and services.
Infrastructure as Code - The process of designing and engineering infrastructure using code within configuration
files and running deployments using software tools.
Configuration as Code - Defining the configuration of Computer and Network infrastructure using code and configuration
files with a focus on speed and consistent reproducibility.
Namespace - A label assigned to a set of resources and processes. Designed so that processes running in a specific namespace
can only access other processes, files and resources that reside within that namespace. One process can be assigned several
namespaces.
Container - An entire operating system running within a virtual namespace on a host system while sharing that host’s
resources with varying degrees of restrictions. Containers are typically used to run a single target program with minimal
overhead required from the host.
Pod - A collection of inter-dependent containers, each running a single target program, that together run as a single
application.
Container Image - A compressed, frozen template of a pre-configured operating system. Used as the foundation to
create containers.
Container Orchestration - The process of creating, managing, and monitoring containers through software automation.
Container Orchestration was founded by Google’s Borg project (now Kubernetes).
Identity Access Management - A system that provides sets of policies, profiles and roles that ensures entities with
resource access are assigned the appropriate level of permissions within an environment.
