CI/CD
Also known as: Continuous Integration · Continuous Delivery · Continuous Deployment
Continuous Integration / Continuous Delivery is the discipline of automatically building, testing, and shipping every code change. CI catches regressions before they merge; CD removes the manual step between merge and production. TantraDev considers a pipeline 'real' only when a clean commit can reach production without a human gate other than a deployment-window check.
Concepts that travel with this one.
Architecture rarely lives in isolation — these are the terms that come up in the same conversation.
GitOps
GitOps is operational discipline that treats a Git repository as the single source of truth for system state — application config, infrastructure, deployment manifests. A reconciliation agent (ArgoCD, Flux) continuously drives the cluster toward whatever Git says it should be. The benefit is auditable change history and a one-revert rollback; the cost is the operational maturity to keep Git authoritative.
Blue-Green Deployment
Blue-green deployment runs two identical production environments side by side. The live environment (blue) serves traffic while the new version (green) is deployed and warmed in parallel. Cutover is a load-balancer flip, and rollback is the same flip in reverse. The cost is double the compute during the window; the benefit is a zero-downtime, instantly-reversible release path.
Canary Release
A canary release routes a small percentage of production traffic (1%, 5%, 25%) to a new version while the rest stays on the previous one. Metrics — error rate, latency, business KPIs — are compared between the two cohorts in real time. The rollout proceeds only if the canary stays inside its SLO. The point is to catch regressions on real traffic with bounded blast radius.
