Скачать или смотреть Reverse Proxy Caching Explained: Memory, Disk & Distributed Cache Levels with Real Architecture

🧠 Description (for YouTube):
Ever wondered what “in-memory” caching really means in NGINX or Varnish? Or how CDNs like Cloudflare cache data across the globe?
In this video, we’ll break down how reverse proxies cache at three levels — RAM, Disk, and Distributed systems — and how they work together to deliver lightning-fast responses ⚡

You’ll learn:
✅ What “in-memory” actually means (whose memory and how it’s used)
✅ How NGINX, Varnish & Cloudflare manage multi-level caching
✅ Cache hit/miss flow explained step-by-step
✅ Real examples, eviction algorithms (LRU/LFU), and architecture diagram

Perfect for backend & DevOps engineers who want to understand how caching at proxy level truly boosts performance 🚀
