Episode notes
Scaling Challenges with Relational Databases
- Relational databases can become bottlenecks when scaling applications.
- Over-provisioning for peak loads wastes resources and increases costs.
Peak Plus Sizing and Unexpected Loads
- Some argue that databases shouldn't exceed 80% utilization to avoid issues.
- Unexpected peak loads, like a Super Bowl campaign, can strain unprepared databases.
Vertical Scaling and Fluctuating Loads
- Vertically scaling relational databases often requires restarts, disrupting service.
- Development and test environments exemplify fluctuating loads, making efficient scaling crucial.
