In-depth .NET Azure Functions: Isolated mode, performance and durable AI agents

Stas Lebedenko

The smallest compute tier in Azure Flex Consumption actually worsens cold starts. Discover the optimal .NET configurations for Isolated workers to slash latency and orchestrate resilient AI agents.

#1 about 3 min

Azure functions hosting plans and migration challenges

Because older consumption plans use Windows containers, teams must update applications to adopt the superior Flex consumption model.

#2 about 3 min

Flex consumption plan features and capacity limitations

Managing the Linux-only Flex consumption plan requires acknowledging missing deployment slots and requesting adequate regional compute quotas.

#3 about 3 min

Adopting the .NET isolated worker model for functions

Transitioning away from legacy in-process logic enables teams to deploy standard console applications featuring multiple output bindings.

#4 about 6 min

Load testing and native AOT pre-compilation performance

Testing unoptimized cold starts reveals how native AOT compilation significantly reduces startup latency across various compute sizes.

#5 about 2 min

Optimizing durable functions scaling with sub-orchestrators

Processing heavy event streams necessitates deploying sub-orchestrators to eliminate single-node bottlenecks found in traditional fan-in patterns.

#6 about 3 min

Tuning dynamic concurrency and durable tasks in host.json

Tuning the default configuration parameters allows Azure to automatically manage concurrent activity execution and reduce host logging overhead.

#7 about 3 min

Best practices for function builds and durable orchestration

Reducing cold start footprints requires trimming framework dependencies and carefully managing connection pools within orchestrated activity functions.

#8 about 4 min

Building durable AI agents with Microsoft agent framework

Executing long-running workflows with human feedback benefits from adopting integrated durability structures within the Microsoft agent framework.

#9 about 5 min

Key takeaways for isolated mode and future migrations

Ensuring predictable performance upon scaling highly depends on establishing thorough load tests before the isolated mode deprecation deadline.
