Frequently asked questions

What are the key differences between horizontal and vertical scaling?

Horizontal scaling involves adding more servers to distribute workload, while vertical scaling increases resources (CPU, RAM) on a single server. Horizontal scaling is generally preferred for its flexibility and cost-effectiveness.

How can I identify potential scalability bottlenecks in my system?

Bottlenecks often lie within databases, stateful services, or components handling synchronous operations. Monitoring resource utilization, response times, and error rates can help pinpoint these areas.

What are common scalability bottlenecks that developers should be aware of?

Common bottlenecks include database limitations (lack of sharding or replication), inefficient code leading to high CPU usage, stateful services struggling with increased connections, and synchronous operations causing delays.
