Infrastructure as Code
Also known as: IaC
Infrastructure as Code (IaC) treats infrastructure the way teams already treat application code — version-controlled, peer-reviewed, repeatably deployable. The point is not that you write code instead of clicking — it is that every change is reviewable, every environment is reproducible, and 'who changed the prod VPC last Friday' has a `git blame` answer. TantraDev ships Terraform on every cloud engagement.
Concepts that travel with this one.
Architecture rarely lives in isolation — these are the terms that come up in the same conversation.
Terraform
Terraform is HashiCorp's declarative infrastructure-as-code tool. You write the desired state (a VPC, an RDS cluster, an IAM role) in HCL and Terraform reconciles cloud reality to match. TantraDev writes Terraform for everything — networks, databases, secrets, monitoring — and hands the state and modules back at the end of every engagement so the runbook works without us.
CI/CD
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.
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.
Building a system where Infrastructure as Code is the load-bearing decision?
