For that, you use the AWS Command Line (AWS CLI) to configure the schedules that send notifications using Amazon SNS. This walkthrough builds a series of schedules to get started with EventBridge Scheduler. Getting started with EventBridge Scheduler Over 270 services and over 6,000 API Actions with AWS SDK targets The following table shows the main differences between EventBridge Scheduler and EventBridge rules:Īble to support throughput in 1,000s of TPSīecause of the schedule limit, you can only have 300 1-minute schedules for max throughput of 5 TPS But to schedule tasks at scale, EventBridge Scheduler is better suited for this task. You can also schedule tasks using Amazon EventBridge rules. You can also use your own AWS KMS encryption keys. In addition, by default, all events in Scheduler are encrypted with a key that AWS owns and manages. If that fails, the message is dropped, since by default there is not a DLQ configured. A dead letter queue is an Amazon SQS queue where events that failed to get delivered to the target are routed.īy default, EventBridge Scheduler tries to send the event for 24 hours and a maximum of 185 times.This improves the success of the task when the target is available. Retries with exponential backoff help to retry a failed task with delayed attempts.If the target is not responding during this time, the event is dropped or sent to a DLQ. Maximum retention time of the event is the maximum time to keep an unprocessed event in the scheduler.This means that the scheduled tasks are dispersed across the time window to reduce the impact of multiple requests on downstream services. Time window allows you to start a schedule within a window of time.You can learn more about each configuration from the Scheduler User Guide. EventBridge Scheduler allows you to configure schedules with a minimum granularity of one minute.ĮventBridge Scheduler provides at-least-once event delivery to targets, and you can create schedules that adjust to different delivery patterns by setting the window of delivery, the number of retries, the time for the event to be retained, and the dead letter queue (DLQ). With EventBridge Scheduler, you can now create single or recurrent schedules that trigger over 200 services with more than 6,000 APIs. Use cases for EventBridge Scheduler are diverse, from simplifying new feature development to improving your infrastructure operations. Also, you can create a series of emails that let your customer knows that their license is expiring so they can purchase a renewal. With Scheduler, you can create a schedule that removes the access to the service when the billing period is over, or when the user cancels their subscription. You want to ensure that their license key is valid until the end of their current billing period. For example, consider a SaaS provider with a subscription model for your customers paying a monthly or annual fee. SaaS providers can also benefit from EventBridge Scheduler, as now they can more easily manage all the different scheduled tasks that their customers have. You can use EventBridge Scheduler to start and stop all the thousands of instances and also respect time zones. You want to make sure that all the instances are started before the stores open and terminated after the business hours to reduce costs as much as possible. These instances are used in different parts of the world during business hours. Or consider a large organization, like a supermarket, with thousands of AWS accounts and tens of thousands of Amazon EC2 instances. You can automate the creation of all the schedules with EventBridge Scheduler, create the task for each of the reminders, and send it to Amazon SNS to send the notifications. One feature that the application provides is that users can add a reminder for a task and be reminded by email one week before, two days before, or on the day of the task due date. When to use EventBridge Scheduler?įor example, consider a company that develops a task management system. Most of these solutions are limited in what services they can trigger and create complexity in managing concurrency limitations of invoked targets that can affect application performance. This can increase application complexity, slow application development, and increase costs, which are magnified at scale. Previously, many customers used commercial off-the-shelf tools or built their own scheduling capabilities. With EventBridge Scheduler, you can schedule one-time or recurrently tens of millions of tasks across many AWS services without provisioning or managing underlying infrastructure. This is a new capability from Amazon EventBridge that allows you to create, run, and manage scheduled tasks at scale. Today, we are announcing Amazon EventBridge Scheduler.
