The AWS Lambda Snapshot Management project is a serverless solution designed to automate the cleanup of unused Amazon EBS (Elastic Block Store) snapshots within an AWS environment. Leveraging the power of AWS Lambda and the Boto3 Python library, this project addresses the challenge of optimizing storage costs by identifying and deleting snapshots that are not associated with any volumes or instances.
The project utilizes AWS Lambda, a serverless computing service, to execute the snapshot management functions. This ensures cost-effectiveness, scalability, and minimal operational overhead.
Boto3, the Amazon Web Services (AWS) SDK for Python, is employed to interact with AWS services. Specifically, it enables seamless communication with the EC2 (Elastic Compute Cloud) service for snapshot identification and deletion.
The Lambda function is designed to identify snapshots that are not attached to any volumes or instances. By implementing custom logic, the solution ensures that only unused snapshots are targeted for deletion.
The Lambda function is triggered on a scheduled basis, allowing for automated and regular execution of the snapshot management process. This ensures that the AWS environment remains optimized over time.
The project incorporates logging mechanisms to capture relevant information about the execution of the Lambda function. Additionally, CloudWatch, AWS's monitoring and observability service, can be configured to provide insights into the execution and performance of the solution.
By automating the identification and deletion of unattached snapshots, the project contributes to cost optimization within AWS, as unnecessary storage costs are reduced.
The core component responsible for executing the snapshot management logic.
Utilizes Boto3 to interact with AWS services. Executes custom logic to identify and mark unattached snapshots. Triggers the deletion process for marked snapshots. Implements logging for monitoring and observability. Scheduled execution for regular automated cleanup.
Integration with the AWS SDK for Python (Boto3) to interact with AWS services programmatically.
Establishes communication with the EC2 service. Retrieves information about volumes, instances, and snapshots.
Amazon Elastic Compute Cloud service responsible for managing virtual machine instances.
Provides information about attached volumes and instances. Used by the Lambda function to identify relationships between snapshots, volumes, and instances.
AWS service for monitoring and observability.
Integrated with the Lambda function for logging. Captures execution details and performance metrics.
AWS CloudWatch Events or EventBridge Rule.
Triggers the Lambda function at scheduled 55AB intervals. Enables automated, regular execution of the snapshot management process.
Serverless environment provided by AWS Lambda.
Scales automatically based on demand. Minimizes operational overhead. Executes the snapshot management logic in isolated environments.
