⚡️ serverless-provisioned-concurrency-autoscaling

Serverless Plugin for AWS Lambda Provisioned Concurrency Auto Scaling configuration.

Usage

Add the NPM package to your project:

$ npm install serverless-provisioned-concurrency-autoscaling

Add the plugin to your serverless.yml:

plugins:
  - serverless-provisioned-concurrency-autoscaling

Configuration

Add concurrencyAutoscaling parameters under each function you wish to autoscale in your serverless.yml.

# minimal configuration

functions:
  hello:
    handler: handler.hello
    provisionedConcurrency: 1
    concurrencyAutoscaling: true

  # full configuration

  world:
    handler: handler.world
    provisionedConcurrency: 1
    concurrencyAutoscaling:
      enabled: true
      maximum: 10
      minimum: 1
      usage: 0.75
      scaleInCooldown: 120
      scaleOutCooldown: 0

That's it! With the next deployment, serverless will add Cloudformation resources to scale provisioned concurrency!

You must provide atleast provisionedConcurrency and concurrencyAutoscaling to enable autoscaling. Set concurrencyAutoscaling to a boolean, or object with configuration. Any omitted configuration will use module defaults.

Defaults

maximum: 10
minimum: 1
usage: 0.75
scaleInCooldown: 120
scaleOutCooldown: 0
