Frédéric, Senior SRE at BlaBlaCar, shares how his team solved the cold start problem for their 1,500 Java microservices using Istio's warm-up capabilities.

You will learn:

- Why Java applications struggle with cold starts and how JIT compilation affects initial request latency
- How Istio's warm-up feature works to gradually ramp up traffic to new pods
- Why other common solutions fail, including resource over-provisioning, init containers, and tools like GraalVM
- Real production impact from implementing this solution, including dramatic improvements in message moderation SLOs at BlaBlaCar's scale of 4,000 pods
