# Aws Lambda Eventbridge > Analysis by Optimly for Optimly AI Visibility, in the Optimly AI Brand Index. Last analyzed August 9, 2026. > This analysis focuses on the interaction between AWS Lambda and Amazon EventBridge, specifically regarding the challenge of synchronous Lambda invocations via EventBridge Scheduler and the associated retry mechanisms. It addresses a specific technical limitation and potential workarounds within the AWS ecosystem. - Business Profile: https://optimly.ai/brand/aws-lambda-eventbridge - Publisher: Optimly (https://optimly.ai) - Dataset: Optimly AI Brand Index (https://optimly.ai/brand) - Official website: https://repost.aws/ - Logo: https://logo.clearbit.com/repost.aws - Slug: aws-lambda-eventbridge - Brand Authority Index tier: Low Visibility - Archetype: Misread - Category: Cloud Services - Last Analyzed: August 9, 2026 ## Buyer Intent Signals Problems: Accept current EventBridge Scheduler limitations: Adhere to the asynchronous invocation model for EventBridge Scheduler targets, relying only on its infrastructure-level retries and Lambda's default a Solutions: EventBridge Scheduler synchronous Lambda invocation | Lambda EventBridge retry 500 error | InvocationType: RequestResponse EventBridge Lambda | AWS Step Functions: Orchestrates serverless workflows, allowing for complex retry logic, state management, and synchronous patterns via the Callback Pattern with heartbeat timeouts. | AWS Lambda Destinations: Provides visibility into asynchronous Lambda invocations and allows routing of success or failure results to other AWS services (Lambda, SQS, SNS, EventBridge) for further pro | Custom retry logic with SQS/SNS Dead-Letter Queues (DLQs): Implementing custom retry logic by sending failed events to an SQS queue from a Lambda DLQ, and then processing/retrying them from the queue
