When your authentication and authorization architecture needs to handle millions of authentication requests per second, standard approaches break down fast. Harsha Reddy, Lead Software Engineer at Klaviyo, has built and scaled service-to-service authentication systems that process massive request volumes without compromising security or performance.

What You'll Learn:

• Architecture patterns that scale to millions of requests per second across hundreds of services
• Token lifecycle management strategies that maintain performance at massive scale
• How to balance security with availability when auth systems face outages
• Authorization models that work in complex service topologies (RBAC, ABAC, PBAC)
• Real-world lessons from scaling auth infrastructure through major growth inflection points

Whether you're scaling an existing microservices architecture or designing authentication for high-volume systems, this session provides tested insights from an engineer who's solved authentication at the scale most teams only dream about.
