From App to Millions of Users: Designing Instagram’s Architecture on AWS

From App to Millions of Users: Designing Instagram’s Architecture on AWS
Instagram is used by millions of people every day, but what happens behind the scenes when millions of users access an application at the same time?
How are requests handled at scale? How is content delivered reliably? How do different services communicate with each other? And how does cloud infrastructure support an application operating at this scale?

In this technical session, we’ll explore the architecture behind large scale applications using Instagram as a reference point and understand how modern systems are designed and scaled using AWS.

What you’ll explore:
• Architecture of large-scale applications
• How systems handle millions of users and requests
• AWS services and cloud infrastructure
• Scalability, reliability, and availability
• Distributed systems and backend architecture
• Key system design principles used in production
