 ## EventBridge Scheduler
 
-**Amazon EventBridge Scheduler** is a fully managed, **serverless scheduler designed to create, run, and manage tasks** at scale. It enables you to schedule millions of tasks across over 270 AWS services and 6,000+ API operations, all from a central service. With built-in reliability and no infrastructure to manage, EventBridge Scheduler simplifies scheduling, reduces maintenance costs, and scales automatically to meet demand. You can configure cron or rate expressions for recurring schedules, set one-time invocations, and define flexible delivery windows with retry options, ensuring tasks are reliably delivered based on the availability of downstream targets. Some EventBridge Scheduler Key Features are:

-1. **Templated targets** – Supports common API operations for Amazon SQS, SNS, Lambda, and EventBridge, allowing you to configure schedules quickly using the console, SDK, or CLI.
-2. **Universal targets (UTP)** – Create customized triggers for over 270 AWS services and 6,000+ API operations using UTP through the console, SDK, or CLI.
-3. **Flexible time windows** – Allows dispersed scheduling for improved reliability when precise timing isn’t required.
-4. **Retries** – Provides at-least-once delivery, with options to retry failed tasks to ensure target availability.

-There is an initial limit of 1,000,000 schedules per region per account. Even the official quotas page suggests, "It's recommended to delete one-time schedules once they've completed." Unfortunately, there’s currently no feature for automatic deletion, which is a bit of a drawback.

 ### Types of Schedules
+
 Types of Schedules in EventBridge Scheduler:
 
 1. **One-time schedules** – Execute a task at a specific time, e.g., December 21st at 7 AM UTC.
 2. **Rate-based schedules** – Set recurring tasks based on a frequency, e.g., every 2 hours.
 3. **Cron-based schedules** – Set recurring tasks using a cron expression, e.g., every Friday at 4 PM.
 
 Two Mechanisms for Handling Failed Events:
+
 1. **Retry Policy** – Defines the number of retry attempts for a failed event and how long to keep it unprocessed before considering it a failure.
 2. **Dead-Letter Queue (DLQ)** – A standard Amazon SQS queue where failed events are delivered after retries are exhausted. DLQs help in troubleshooting issues with your schedule or its downstream target.
