Solving Cold Starts: Uses Istio to Warm Up Java Pods, with Frédéric Gaudet
Description
If you're running Java applications in Kubernetes, you've likely experienced the pain of slow pod startups affecting user experience during deployments and scaling events.
Frédéric Gaudet, 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 in Kubernetes environments
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
