Flex Consumption: Build Serverless Apps with High-Throughput and Virtual Networking Features
summary
Introduces Flex Consumption: a Linux-only Azure Functions hosting plan that chooses 0.5/2/4 GB instances, exposes per-instance concurrency, and shares container infrastructure with Container Apps. Demonstrates integrated load testing and a performance optimizer hitting about 30,000 requests per second (peaks ~58k) and a GitHub case sustaining 1.6 million messages per second. Adds VNet support with private endpoints, per-function scaling, always-ready instances, and billing aligned to chosen instance GBs; demos show it works at large scale.
