Скачать или смотреть Your App Is Slow — Caching Fixes This

Slow APIs, high database load, and rising latency are some of the most common performance problems in production systems.

In this video, I explain how caching dramatically improves system performance, reduces database pressure, and helps backend systems scale under real traffic.

You’ll learn:

Why systems slow down without caching

What caching really is (simple explanation)

Read-through vs write-through cache

Cache hit vs cache miss

Where to use cache (API, DB, CDN)

Common caching mistakes that cause bugs

When caching helps — and when it hurts

This video is perfect for developers working with Node.js, backend systems, microservices, Redis, distributed systems, and system design interviews.
