🚀Case Study #2 System Design & Capacity Planning WhatsApp like application for 100 Million Users

In this video, we design WhatsApp for 100 Million Users and perform complete capacity planning from scratch.

We estimate:

✅ Daily Active Users (DAU)
✅ Messages per Day
✅ Read RPS
✅ Write RPS
✅ Peak Traffic Estimation
✅ Storage Requirements
✅ Bandwidth Consumption
✅ Database Sizing
✅ CDN Requirements
✅ Backup & Disaster Recovery Strategy
✅ Future Growth Planning
✅ AI-Powered Features and Infrastructure Impact

We start with realistic assumptions, validate estimates using modern AI tools such as ChatGPT, Claude, Gemini, and EURI, and then build a scalable architecture capable of serving hundreds of millions of users.

Topics Covered:

• User Traffic Estimation
• Read/Write Scaling
• Database Selection (Cassandra, PostgreSQL, Redis)
• Kafka Message Queue Design
• Media Storage using S3
• CDN Optimization
• High Availability & Disaster Recovery
• Kubernetes-based Scaling Strategy
• WhatsApp Architecture Walkthrough
This video is perfect for:

✔ System Design Interview Preparation
✔ Software Engineers
✔ Solution Architects
✔ Backend Developers
✔ Cloud Engineers
✔ Tech Leads
