Single region architecture

Disadvantages

1. In cases when the entire region experiences an outage due to natural disasters or other problems.
   1. Increased risk downtime.
   2. Data loss and corruption
   3. Limited disaster recovery
2. Performance bottlenecks: Users farther away from the data center may experience increased latency and slower response times.

Resolves performance bottlenecks

Disadvantages

1. Data fragmentation and inconsistency
2. Increased management overhead
3. Data merge and movement complexity
4. Increased operational overhead
