☁️ AWS 👨‍💻RPO vs RTO 💪 Explained 🚀#aws #awssolutionsarchitect

These terms refer to different disaster recovery strategies in AWS, each with varying levels of readiness and cost. Here's an explanation of each:

Pilot Light:

Minimal version of the core system always running in the cloud
Critical data replicated continuously
Non-critical systems remain off until needed
Faster recovery than cold start, but slower than warm standby
Lower cost than warm standby

Warm Standby:

Scaled-down but fully functional version of the system always running
Can handle production load, but at reduced capacity
Faster recovery than pilot light
Higher cost than pilot light due to always-on resources

Multi-Site:

Full production environment replicated across multiple AWS Regions
Active-active or active-passive configuration
Fastest recovery time (near-instantaneous failover possible)
Highest cost due to full redundancy

Each strategy offers a different balance between cost, complexity, and recovery speed. The choice depends on your specific business requirements, RPO/RTO goals, and budget constraints.
