Automating Savings Plans with Amazon EventBridge

EventBridge helps you automate your AWS services and respond automatically to system events such as application availability issues or resource changes. Events from AWS services are delivered to EventBridge in near-real time. Events are emitted on a best-effort basis. Based on the rules you create, EventBridge calls one or more target actions when an event matches the values that you specify in a rule.

The actions that can be automatically triggered include the following:

Some examples of using CloudWatch Events with Savings Plans include:

Sample events from Savings Plans

This section includes example events from Savings Plans. Savings Plans generate two types of events. State change events that are triggered upon state changes, and state change alerts events that notify an upcoming state change that will occur in one or seven days.

Savings Plans state change event

Savings Plans state changes are generated when a Savings Plan transitions from one state to another. For example, payment-pending state changes to active, or an active state changes to retired.

{"version": "0",
 "id": "999cccaa-eaaa-0000-1111-123456789012",
"detail-type": "Savings Plans State Change",
 "source": "aws.savingsplans",
"account": "123456789012",

"detail": {
    "severity": "INFO",

    } 
}

The state change event contains fields for resources (Savings Plans ARNs), previous state, current state, severity, and message.

Savings Plans state change alert event

Savings Plans state change alerts are generated when a Savings Plan transitions from the queued state to active, or active to retired in one or seven days. This is a proactive notification to alert you if any Savings Plan is retiring, or a queued state is fulfilled.

    "message": "queued savings plans will go to active state on 2020-09-17" 
    }
}
