Notification on breaching forecasted cost

This example is handy for keeping control over your private AWS Bill. For myself I aim to not spent more than 10 Euro / 10 USD per month and this alarm reminds me.

const app = new cdk.App();
const stack = new Stack(app, "BudgetNotifierStack");

// Define the SNS topic and setup the resource policy
const topic = new Topic(stack, "topic");

const statement = new PolicyStatement({
  effect: Effect.ALLOW,
  principals: [new ServicePrincipal("budgets.amazonaws.com")],
  actions: ["SNS:Publish"],
  sid: "Allow budget to publish to SNS"
});
topic.addToResourcePolicy(statement);

// Setup the budget notifier and pass the ARN of the SNS topic
new BudgetNotifier(stack, "notifier", {
  topicArn: topic.topicArn,
  // Filter on the availability zone `eu-central-1`
  availabilityZones: ["eu-central-1"],
  costCenter: "myCostCenter",
  // Limit and unit defining the budget limit
  limit: 10,
  unit: "USD",
  // When breaching the threshold of 85% of the 10 USD notifications will be send out.
  threshold: 85,
  notificationType: NotificationType.FORECASTED,
});

Notification via e-Mail

As alternative to the notification via SNS you can specify a list of e-mail recipients.

const app = new cdk.App();
const stack = new Stack(app, "BudgetNotifierStack");

new BudgetNotifier(stack, 'notifier', {
  recipients: ['[e-mail]'],
  // Filter on the availability zone `eu-central-1`
  availabilityZones: ['eu-central-1'],
  costCenter: 'MyCostCenter',
  // Limit and unit defining the budget limit
  limit: 10,
  unit: 'USD',
  // When breaching the threshold of 85% of the 10 USD notifications will be send out.
  threshold: 85,
  notificationType: NotificationType.FORECASTED,
});
