Generally Available: Application Gateway for Containers – Slow start
Slow start is now generally available as a load balancing algorithm in Application Gateway for Containers. This feature improves stability and performance during backend scale-up by gradually increasing traffic to new pods over a configurable time window.
Algorithm benefits:
- Smooth scale-up: Avoid sudden traffic spikes that can cause cold-start delays or failures.
- Improved reliability: Ensure new pods are ready before handling peak load.
- Predictable performance: Maintain consistent response times during scaling events and rolling updates.
