When should I choose active-active over active-passive?

Choose active-active when you need near-zero RTO and global performance, though it increases costs and database complexity. Choose active-passive for simpler management and lower costs where some failover time is acceptable.

What is the difference between RTO and RPO?

RTO (Recovery Time Objective) is the target time to restore a system after failure, while RPO (Recovery Point Objective) is the maximum amount of data loss measured in time.

Does this skill work with AWS, Azure, and GCP?

Yes, the patterns and strategies provided are cloud-agnostic and applicable across all major cloud providers and global traffic managers like Cloudflare.

What is the primary benefit of multi-region deployment?

The primary benefits are high availability (surviving region-wide failures), lower latency for global users, and compliance with local data residency laws.

How does this skill handle database consistency?

It provides patterns for synchronous and asynchronous replication, conflict resolution strategies like Last Write Wins (LWW), and guidance on using globally distributed databases like Spanner or CockroachDB.
