Lambda Function Basic

📦 Overview

This Terraform module provisions a basic AWS Lambda function with a configurable runtime, handler, and pre-packaged source code archive. It provides a fast, repeatable way to deploy serverless functions in any AWS environment.

---

✅ Key Features

• Deploys a Lambda function with defined runtime and handler
• Accepts zipped source archive via source_path
• Supports tagging for environment and visibility
• Lightweight and ideal for serverless automations and microservices

---

💼 Use Cases

• Webhook handlers or lightweight APIs
• Scheduled tasks via EventBridge
• Automation scripts or real-time log processors
• Prototyping serverless workloads
