CI/CD Concepts
Continuous Integration and Continuous Delivery are foundational practices that enable teams to deliver software frequently, reliably, and safely. These practices reduce integration risk, accelerate feedback loops, and make releases a routine business decision rather than a high-stakes technical event.
CI/CD Philosophy
At Synapse Studios, we view CI/CD as:
- Risk reduction through frequency - Integrating and deploying often makes each change less risky
- Fast feedback - Discover problems within minutes or hours, not weeks
- Always releasable - Mainline stays deployable at all times
- Business enablement - Release timing becomes a business decision, not a technical constraint
Core Practices
Continuous Integration
The discipline of integrating work frequently—multiple times per day—with automated verification to detect problems immediately.
Key Principles:
- Frequent commits to mainline (at minimum daily, ideally many times per day)
- Automated build and test on every commit
- Fix broken builds immediately
- Keep mainline always releasable
- Work in small, stable increments using TDD
Essential Requirements:
- Comprehensive automated test suite
- Trunk-based development (no long-lived branches)
- Fast build times (under 10 minutes for commit stage)
- Team discipline and cultural commitment
- Feature flags for incomplete work
Continuous Delivery
Building software so it can be released to production at any time through automated deployment pipelines.
The Deployment Pipeline:
- Commit Stage - Fast feedback (under 10 minutes) with unit tests and packaging
- Acceptance Stage - Automated business requirement verification
- Optional Stages - Performance, security, manual exploratory testing
- Production Deployment - Manual trigger (CD) or automatic (Continuous Deployment)
Key Capabilities:
- Software remains deployable throughout development
- Push-button deployment to any environment
- Fast, automated feedback on production readiness
- Release timing as a business decision, not technical constraint
The Relationship
