Power Schedules#

Use the Power Schedule feature to optimize the use of computational resources to improve efficiency, reduce costs, and minimize energy consumption. Its objective is to implement a power management policy that enables users to schedule instances to start/stop according to predefined schedules. This policy is applicable across multiple cloud platforms, including AWS, MS Azure, GCP, and Alibaba.

The entry point to the power schedule page is a Power Schedules item in the Policies section of the menu.

Base principals#

Power Schedules is a feature that allows instances in the cloud to be powered on and off based on a predefined schedule.

Notes:

A resource can have only one power schedule.
The schedule runs every day.
A single power schedule can include multiple power-on and power-off time triggers.
Supported on AWS, Azure, Alibaba Cloud, and GCP.

Permissions required for powering on/off instances:

AWS
- ec2:StartInstances, ec2:StopInstances
  - Allows starting or stopping EC2 instances a user has tagged, programmatically and in the console.
  - Source: AWS Identity and Access Management.
Azure
- Microsoft.Compute/virtualMachines/start/action
- Microsoft.Compute/virtualMachines/deallocate/action
  - Allows users to start/stop specific Azure virtual machines (VMs).
