Scalr - Autoscaling for Clouds
Scalr allows to scale Cloud instances based on policy checks in a configurable interval. Scalr has 2 pluggable interfaces: cloud, policy.
This is the connector to the API of your Cloud provider. It reads current available servers of your Scalr group and scales up and down based on a calculation factor received from one or more policies:
A policy defines check of a target value (amount of CPU, amount of HTTP requests, etc) and where to gather the metric from, such as the following.
Multiple policies can be used in a single config.
- HTTP endpoint returning JSON
- Random metric (for testing)
Your Cloud and policy configuration are defined by a configuration. Scalr reads its configuration on every run and can be changed inbetween runs.
- Static YAML file (see a sample)
