Resource Scheduler

Resource Scheduler Automation

The Resource Scheduler is a Continuous automation that powers SkySaver’s core scheduling functionality. It continuously monitors your AWS resources and applies schedules based on resource tags.

How It Works

graph LR
    A[Resource Scheduler] --> B[Scan Resources]
    B --> C[Check Tags]
    C --> D{Schedule Found?}
    D -->|Yes| E[Apply Schedule]
    D -->|No| F[Skip Resource]
    E --> G[Start/Stop/Scale]

Scan - The scheduler scans all enabled resource types across configured regions
Match - Resources with matching schedule tags are identified
Evaluate - Current time is compared against schedule periods
Execute - Resources are started, stopped, or scaled according to the schedule

Supported Resources

Resource Type	Actions	Configuration Options
EC2 Instances	Start/Stop	Instance type changes
RDS Instances	Start/Stop	Instance class changes
Lambda Functions	Scale concurrency	Reserved/provisioned concurrency
Auto Scaling Groups	Scale capacity	Desired, min, max instances

Prerequisites

Before the Resource Scheduler can manage resources:

Enable Services - In Project Defaults, enable the resource types you want to schedule
Configure Regions - Add all regions where schedulable resources exist
Create Schedules - Define at least one schedule in SkySaver
Tag Resources - Apply schedule tags to AWS resources

Configuration

Project Defaults

Navigate to Project Defaults to configure scheduler settings:

Enabled Services - Toggle which resource types the scheduler manages
Regions - List of AWS regions to scan
Default Tag - The tag key used for schedule matching

Account-Level Overrides

Individual AWS accounts can override the default tag:

Navigate to Accounts > Manage
Click on the account
Update the Tag field
Click Save

Schedule Matching

The Resource Scheduler matches resources to schedules using tags:

AWS Resource Tag	SkySaver Schedule
Key: `Schedule`	Schedule with matching name
Value: `dev-business-hours`	Applied to resource

Execution Timing

The scheduler evaluates resources continuously and takes action when:

A period starts - Resources are started/scaled up
A period ends - Resources are stopped/scaled down
Outside all periods - Resources are in their default (inactive) state

Monitoring

Track scheduler activity:

Dashboard - Recent scheduling actions
Automation Reports - Detailed execution logs
AWS CloudTrail - API call history

Troubleshooting

Issue	Possible Cause	Solution
Resource not scheduled	Missing tag	Verify tag key and value match
Schedule not executing	Service not enabled	Enable service in Project Defaults
Region not scanned	Region not configured	Add region to Project Defaults
Permission denied	IAM role issue	Verify CloudFormation template is deployed
