Deployment Strategy & Release Management
How we deploy code to your live environment is as important as how we write it. A poor deployment process can undo months of good development. This article explains our approach to safe, reliable deployments.
Deployment Pipeline (CI/CD)
We use Continuous Integration / Continuous Deployment (CI/CD) pipelines to automate code deployment. When code is merged and tests pass, the pipeline automatically:
- Runs all automated tests
- Builds the application
- Deploys to the appropriate environment (staging or production)
- Runs smoke tests post-deployment to verify the deployment succeeded
Production Deployment Gate
No code is deployed to production without:
- All automated tests passing
- Code review approval by a senior engineer
- Staging sign-off from the QA team
- Your sign-off (for major releases) or Project Manager sign-off (for minor releases)
Release Schedules
For ongoing projects, we typically release to production:
- Major releases: At the end of each sprint or milestone, after UAT
- Minor releases / bug fixes: As needed, typically Tuesdays or Thursdays to avoid Monday morning peaks and Friday afternoon risk
- Emergency fixes: Immediately after testing, regardless of day
Rollback Plan
Every production deployment is reversible. If a deployment causes unexpected issues, we can roll back to the previous version within minutes. Your Project Manager will notify you immediately if a rollback is required and why.
Zero-Downtime Deployments
For critical services, we implement zero-downtime deployment strategies (blue/green deployments, rolling updates) so that production releases do not cause visible interruption to your users.
