Day 53 - Functions on LMI

Date: 2025-11-19 (Wednesday)
Status: “Planned”

Creating and Publishing Functions

Create functions as usual, but bind them to a capacity provider and publish a version to launch instances.

Supported Features

  • Packaging: ZIP or OCI
  • Runtimes: Java, Python, Node, .NET
  • Layers, extensions, function URLs, response streaming, durable functions
  • 15-minute timeout (longer via durable functions)

Resource Settings

  • Memory/CPU shapes influence instance type selection
  • Multi-concurrency per instance available; plan for throughput vs. cost
  • Multiple functions can share one capacity provider (shared pool)

Workflow

  1. Create capacity provider (VPC, role, instance rules)
  2. Create function with provider ARN
  3. Publish version to trigger instance provisioning and deploy execution environments
