Automated builds triggered by git commits with comprehensive testing including
unit tests, integration tests, security scans, and performance benchmarks.
Parallel build pipeline with dependency caching for faster feedback.
3
Staging Environment
Production-like environment for final validation with full feature testing,
load testing, and integration verification. Automated deployment with
rollback capabilities and comprehensive monitoring.
4
Production Deployment
Blue-green deployment strategy with zero-downtime releases. Automated
health checks, gradual traffic shifting, and immediate rollback capabilities.
Multi-region deployment with automatic failover.
5
