AWS Resource Management and Reporting

Table of contents

Overview

This project provides a solution for managing AWS resources, including EC2 instances and RDS databases, based on tags and generating reports via email using AWS Lambda, SNS (Simple Notification Service), and CloudWatch Events.

Features

1. Schedule AWS Resources

  • Tag-Based Scheduling: Resources are scheduled for start and stop operations based on specific tags.

  • EC2 Instance Management: EC2 instances are started and stopped according to their schedule tags.

2. Reporting of AWS Resources

  • Hashnode-Formatted Reports: The project generates Hashnode-formatted reports detailing AWS resource information.

  • Email Notifications: Reports are sent via email using AWS SNS.

How It Works

1. Tagging Resources

Ensure that the AWS resources you want to schedule (EC2 instances and RDS databases) are appropriately tagged. For scheduling, a common tag like Schedule can be used.

2. Lambda Functions

Two Lambda functions have been created:

  • Start Resources Lambda: This function is triggered by a CloudWatch Events rule to start resources based on their schedule tags.

  • Stop Resources Lambda: This function is triggered to stop resources as per their schedule tags.

3. CloudWatch Events Rules

CloudWatch Events rules are configured to trigger the Lambda functions at scheduled intervals, based on the Schedule tags of the resources.

4. SNS for Notifications

  • Amazon SNS topics are used to send notifications and reports.

  • A Lambda function generates Hashnode-formatted reports and publishes them to an SNS topic.

  • Subscribers to this topic receive reports via email.

Setup Instructions

Follow these steps to set up and use the project:

  1. Tag Your Resources: Ensure that your AWS resources are tagged appropriately with a Schedule tag.

  2. Lambda Configuration: Create two Lambda functions - one for starting resources and one for stopping them. Customize the functions to match your AWS environment.

  3. CloudWatch Events Rules: Configure CloudWatch Events rules to trigger the Lambda functions based on schedule tags.

  4. SNS Topics: Create SNS topics for notifications and reports. Configure the Lambda function to publish reports to the desired SNS topic.

  5. Testing: Test the setup by manually triggering CloudWatch Events rules and monitor Lambda executions.

  6. Email Subscriptions: Subscribe to the SNS topic to receive Hashnode-formatted AWS resource reports via email.
