06. Amazon CodeGuru Overview

Amazon CodeGuru is a machine learning–powered developer tool that helps improve code quality and application performance.

Component	Description
CodeGuru Reviewer	Performs automated code reviews using static code analysis to detect issues such as bugs, resource leaks, and security vulnerabilities.
CodeGuru Profiler	Monitors application performance at runtime to detect inefficiencies, excessive CPU use, and cost optimization opportunities.

🧠 How It Works

Analyzes code in repositories such as CodeCommit, GitHub, and Bitbucket.
Provides actionable recommendations during code commits and pull requests.
Detects:
- Critical issues
- Security vulnerabilities
- Resource leaks and input validation flaws
Learns from:
- Thousands of open-source repositories
- Internal Amazon.com repositories
Languages supported: Java and Python

Use Case Example:

Automatically detect a potential memory leak in your Java service before deployment.

Monitors your application in production or pre-production environments.
Identifies runtime inefficiencies and cost optimization opportunities.
Provides:
- CPU and memory utilization insights
- Heap summaries for memory-heavy objects
- Anomaly detection for abnormal runtime behavior
Works on both AWS Cloud and on-premises applications.
Adds minimal overhead during performance monitoring.

Use Case Example:

Identify a logging function that consumes excessive CPU time and optimize it.
