Why Learn System Design?

System design is the backbone of every successful tech company. It's what allows apps like Instagram to serve billions of photos and Netflix to stream videos to millions of users simultaneously.

๐Ÿ“ˆ

Scalability

System's ability to handle increased load

Types:
  • โ€ข Horizontal (add more servers)
  • โ€ข Vertical (upgrade existing servers)
Example:
Netflix adding more servers during peak hours
๐Ÿ›ก๏ธ

Reliability

System continues to work correctly during failures

Types:
  • โ€ข Fault tolerance
  • โ€ข Redundancy
  • โ€ข Graceful degradation
Example:
WhatsApp working even when some servers are down
โšก

Availability

System remains operational and accessible

Types:
  • โ€ข 99.9% uptime
  • โ€ข Disaster recovery
  • โ€ข Geographic distribution
Example:
Google Search being available 24/7 worldwide
๐Ÿ”„

Consistency

All nodes see the same data at the same time

Types:
  • โ€ข Strong consistency
  • โ€ข Eventual consistency
  • โ€ข Weak consistency
Example:
Bank transactions showing correct balance immediately
