This is still under consideration, so Iā€™d appreciate any advice.

:bullseye: Objectives

  • Full automation from error detection to notification and resolution

  • Error summarization and automated fixes with an AI Agent

  • Achieve automatic updates of Infrastructure as Code (IaC)

:counterclockwise_arrows_button: Flow

  1. EC2 Error Occurs

    • An error occurs on the EC2 instance

  2. Error Detection & Trigger

    • CloudWatch detects the error and triggers Lambda

  3. Error Forwarding

    • Lambda sends error details via HTTP POST

  4. n8n Webhook

    • n8n webhook receives the request and initiates processing

  5. Error Analysis with AI

    • LLM Chain generates a prompt ā†’ Gemini invoked ā†’ Error details summarized

  6. Google Chat Notification

    • Error summary automatically sent to Google Chat

  7. Automated Error Fix

    • AI Agent generates a fix proposal

    • Infrastructure code automatically updated via GitHub MCP

:hammer_and_wrench: Tech Stack

  • AWS CDK: Infrastructure as Code for AWS environment

  • n8n: Workflow automation after error detection

  • Gemini AI: Error summarization and prompt processing

  • Google Chat: Notification channel

  • GitHub MCP: Automatic updates of infrastructure code

:light_bulb: What This Enables

  • End-to-end automation from incident ā†’ notification ā†’ resolution

  • Faster error analysis with AI

  • Continuous alignment with the latest state through IaC auto-updates

:warning: Considerations

  • Accuracy and risk management of automated fixes

  • Scope of application (all errors vs. specific patterns)

  • Rollback strategy design
