DevOps is a culture and set of practices that unite development and operations to deliver software faster and more reliably. This visual guide covers the DevOps lifecycle, CI/CD, infrastructure as code, monitoring, and deployment strategies.
DevOps combines development and operations to ship software faster, safer, and more reliably.
Plan, build, test, release, deploy, operate, and monitor in a continuous loop.
CI/CD automates integrating, testing, and deploying code so changes reach users quickly.
CI merges and automatically tests code changes frequently to catch bugs early.
Delivery prepares releases automatically; deployment ships them to production automatically.
A pipeline is an automated sequence: build, test, scan, and deploy on every change.
Git tracks code history and enables collaboration and safe rollbacks.
IaC defines servers and infrastructure in code so it’s repeatable and version-controlled.
Tools like Ansible keep server configurations consistent and automated.
Monitoring tracks system health; logging records events for debugging and audits.
Containers package an app with its dependencies so it runs the same everywhere.
Orchestration tools like Kubernetes automate deploying and scaling many containers.
Run two environments and switch traffic to the new one for zero-downtime releases.
Roll out changes to a small percentage of users first to catch problems early.
A rollback reverts to a previous stable version when a deployment fails.
GitHub Actions, GitLab CI, and Jenkins are widely used for automation pipelines.
DevOps is the culture and practices; SRE applies engineering to reliability with measurable goals.
Observability uses metrics, logs, and traces to understand what a system is doing internally.
Store API keys and passwords securely in vaults, never in source code.
Automate everything, deploy small changes often, monitor continuously, and fail fast.
