Checklist Items (22)
Define Project Goals and Requirements
Clarify business objectives, success metrics, and functional/non-functional requirements.
Identify Key Stakeholders and Their Expectations
List product owners, developers, ops, security, and end‑user representatives.
Set Up Version Control System
Choose a Git hosting service and initialize repositories for source code and IaC.
Select Repository Hosting (e.g., GitHub, GitLab, Bitbucket)
Evaluate features like pull requests, protected branches, and CI integration.
Define Branching Strategy (e.g., GitFlow, Trunk-Based)
Document how feature, release, and hotfix branches will be used.
Configure Access Controls and Permissions
Set role‑based access, enforce 2FA, and protect main branches.
Implement Continuous Integration (CI)
Automate building and testing on every code change.
Choose a CI Platform (e.g., Jenkins, GitHub Actions, GitLab CI)
Select based on ecosystem, pricing, and scalability needs.
Configure Build Pipeline Stages
Define steps: checkout, compile, unit test, static analysis, and artifact storage.
Set Up Automated Test Execution
Run unit, integration, and lint tests; fail fast on errors.
Implement Continuous Delivery/Deployment (CD)
Automate release to staging and production environments safely.
Select CD Tool (e.g., Argo CD, Spinnaker, AWS CodeDeploy)
Pick a tool that supports your deployment strategy and infrastructure.
Define Deployment Strategies (Blue/Green, Canary, Rolling)
Choose strategy based on risk tolerance and rollback requirements.
Implement Automated Rollback Mechanism
Ensure failed deployments trigger automatic rollback to previous version.
Adopt Infrastructure as Code (IaC)
Manage servers, networks, and services via version‑controlled definitions.
Select IaC Framework (Terraform, Pulumi, AWS CDK)
Evaluate language support, state management, and provider coverage.
Write Modular, Reusable Templates
Break infrastructure into modules (network, compute, database) for reuse.
Store State Securely and Enable Locking
Use remote backends (e.g., S3 with DynamoDB locking) to prevent conflicts.
Establish Monitoring and Logging
Gain visibility into system health and application performance.
Choose Monitoring Stack (Prometheus + Grafana, Datadog, New Relic)
Select based on metrics collection, alerting, and dashboard capabilities.
Set Up Alerting for Critical Metrics
Define thresholds for CPU, memory, latency, and error rates; route to on‑call.
Implement Centralized Log Aggregation (ELK, Loki, Fluentd)
Collect, index, and search logs from all services in one place.
Integrate Security Practices (DevSecOps)
Shift security left by automating scans and policy checks.
Add Static Application Security Testing (SAST) to CI
Run tools like SonarQube or Bandit on every pull request.
Add Dynamic Application Security Testing (DAST) in Staging
Scan running applications for vulnerabilities with OWASP ZAP or Burp Suite.
Automate Dependency Vulnerability Scanning
Use Dependabot, Snyk, or Trivy to flag vulnerable libraries.
Create Incident Response and Runbooks
Prepare for outages with documented procedures and clear responsibilities.
Define Incident Severity Levels and Escalation Paths
Establish SEV1‑SEV4 categories and who to notify at each level.
Create Standardized Runbook Templates
Include steps for detection, mitigation, communication, and post‑mortem.
Establish On‑Call Rotation and Escalation Schedule
Use tools like PagerDuty or Opsgenie to manage rotations and notifications.
