Fundamentals of Software Performance

End-to-end software performance fundamentals: latency, throughput, percentiles, bottlenecks, and measuring user-perceived speed without breaking reliability.
Diagram showing the performance loop: measure, explain, change one thing, verify.

Fundamentals of Software Quality Assurance

Software quality assurance fundamentals, why QA exists, how it differs from testing, and how teams build quality into how they work.
Abstract illustration showing a feedback loop for software quality: prevention, detection, and learning.

What Is a Retry Storm?

Retry storm: when retries multiply load and turn partial failures into outages. Learn how they happen, how to detect them, and how to prevent them.
Diagram showing a retry storm as a feedback loop of increasing load and tail latency.

What Is a Thundering Herd?

Thundering herd: when many clients do the same work at once and overload a dependency. Understand why it happens, what it looks like, and how to reduce risk.
