Containerd is an industry-standard container runtime that manages the complete container lifecycle on a host, including image transfer, storage, execution and supervision, and is used directly by platforms such as Kubernetes and Docker.

Ansible is an open-source, agentless automation engine that uses declarative YAML playbooks and SSH or WinRM to configure systems, deploy applications and orchestrate multi-node workflows without installing persistent client software on managed nodes.

Terraform is HashiCorp's infrastructure-as-code tool for declaratively defining, planning and applying changes to cloud and on-premises infrastructure through provider plugins and a state-tracked execution model.

GitOps is an operational model that uses a version-controlled Git repository as the single source of truth for declarative infrastructure and application state, with automated reconciliation agents continuously converging live systems towards that declared state.

Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes that continuously reconciles cluster state against a Git repository, alerting on and optionally correcting drift.

Docker is a container platform that packages an application with its dependencies into a portable, isolated runtime unit called a container, using OS-level virtualisation rather than full hardware emulation.
