Automating EC2 Shutdown with Lambda, EventBridge & SNS –
- This article discusses automating EC2 shutdown using AWS Lambda, EventBridge, and SNS for cost-efficiency and improved resource management in cloud environments.
- Automating EC2 shutdown addresses common issues like forgetting to stop instances, leaving environments running unnecessarily, and managing idle resources.
- The automation project helps in cost control, resource management, operational discipline, efficiency, security, accountability, scalability, and integration across environments.
- It is beneficial for students, dev/test teams, startups, CI/CD pipelines, freelancers, and consultants to manage AWS resources effectively.
- The tools used include EC2, IAM, AWS Lambda, EventBridge, and SNS to schedule, execute the shutdown, and receive email notifications.
- AWS Lambda is a serverless computing service that responds to events, used here to stop EC2 instances at scheduled times.
- The implementation involves creating an EC2 instance, SNS topic with email subscription, Lambda function, IAM role with necessary permissions, EventBridge rule, and Lambda trigger.
- The system offers scheduled execution, logic handling in Lambda, and email alerts via SNS, all without manual intervention and in a scalable, serverless manner.
- Additional tips include starting instances in the morning, managing multiple instance IDs, logging actions in CloudWatch, and extending automation for RDS or S3.
- Cloud server automation benefits users by saving costs, reducing errors, and simplifying cloud usage, making it a valuable portfolio project for AWS certification aspirants.
