DevOps Architecture & Standards

🧠 Core Philosophy

Automate Everything: If it's done twice, script it.
Infrastructure as Code (IaC): No click-ops. All infra must be defined in code (Terraform, Pulumi, Ansible).
Security First: Shift security left. Manage secrets via Vault/KMS, not env vars.
Observability: You can't fix what you can't see. Logs, Metrics, and Traces are mandatory.

🎛️ Decision Engine & Routing

STEP 1: Context Analysis Before acting, determine the stack components using the Comparison Tables below.

1. Cloud Provider Selection

Feature	AWS	GCP	Azure	Vercel/Supabase
Best For	Enterprise, complex granular control	Data/AI, K8s (GKE)	Enterprise Windows/AD integration	Frontend/Jamstack, Quick MVP
Compute	EC2, Lambda, ECS/EKS	GCE, Cloud Run, GKE	Azure VM, Functions, AKS	Edge Functions
Storage	S3, EBS, EFS	GCS, Persistent Disk	Blob Storage, Files	Storage Bucket
Database	RDS, DynamoDB, Aurora	Cloud SQL, Firestore, Spanner	SQL Database, CosmosDB	Postgres (Supabase)

2. Codebase Normalization Tools

Feature	Husky + Lint-staged	Lefthook	Biome	ESLint + Prettier
Type	Git Hooks (Node.js)	Git Hooks (Go)	All-in-one Toolchain	Linter + Formatter
Speed	Standard	Fast	Extremely Fast	Standard
Best For	Standard JS/TS Projects	Monorepos / Polyglot	Greenfields / Speed	Legacy / Complex Rules

3. IaC Tool Selection

Feature	Terraform	Pulumi	Ansible	CDK (AWS/TF)
Language	HCL (Declarative)	TS/Python/Go (Imperative)	YAML (Configuration)	TS/Python (Imperative)
State	Remote state file (S3/GCS)	Pulumi Service / S3	No state (Idempotent scripts)	CloudFormation / TF State
Use Case	Industry Standard, Multi-cloud provisioning	Dev-friendly, Logic-heavy infra	Config Mgmt, Mutable infra	AWS-centric, Type-safety

4. CI/CD Platform Selection

Feature	GitHub Actions	GitLab CI	Jenkins	CircleCI
Integration	Native to GitHub	Native to GitLab	Self-hosted, Plugins	Fast, SaaS-first
Config	YAML (`.github/workflows`)	YAML (`.gitlab-ci.yml`)	Groovy (Jenkinsfile)	YAML (`.circleci/config.yml`)
Best For	Open Source, Integrated flow	Integrated DevSecOps	Legacy / Highly Custom Enterprise	High Performance

📚 Dynamic Knowledge Base

ACTION: Load the specific reference based on your decision above.

Cloud Infrastructure (AWS/GCP/Azure): Load cloud-providers.md
Infrastructure as Code (Terraform/Pulumi): Load iac-tools.md
CI/CD Pipelines (GHA/GitLab): Load ci-cd-pipelines.md
Containers & Orchestration (Docker/K8s: Load container-orchestration.md
Observability & Security (Monitoring/Logging): Load observability-security.md
Codebase Normalization (Husky/Linting): Load codebase-normalization.md

[!TIP] Long-tail Tools: If a user asks for a tool NOT listed above (e.g., DigitalOcean, TravisCI), use search_web to find the official "Quick Start" and "Best Practices" documentation.

🛡️ Security & Compliance Standards

Least Privilege: IAM roles must be scoped strictly.
Encryption: At rest (KMS) and in transit (TLS 1.2+).
Scanning: SAST (SonarQube), DAST (OWASP ZAP), Container Scanning (Trivy).
