• Big Bang Deployment:
  • Involves pushing all changes at once, causing short downtime; careful preparation and testing are crucial, with rollback as an option.
• Rolling Deployment:
  • Updates different server parts incrementally, preventing downtime and allowing early issue detection; however, it's slower and lacks targeted rollouts.
• Blue-Green Deployment:
  • Uses two identical environments; one serves live version while the other tests new version; seamless transitions and rollbacks, but resource-intensive.
• Canary Deployment:
  • Tests new version on a small subset (canaries) before full-scale rollout, offering safety net, control, and targeted rollouts; requires careful monitoring.
• Feature Toggle:
  • Manages specific new features within an application; allows turning features on or off for certain users, offering control, A/B testing, but needs careful management.
