# Day 33: Create a Lambda Function

Welcome back to Day 33. Today we will learn how to create a lambda function from AWS management console.

### What is Lambda function?

An **AWS Lambda function** is a **serverless compute service** that lets you run code **without provisioning or managing servers**. You just write the code, upload it, and AWS runs it **automatically in response to events**.

## Key characteristics

### 🧠 Serverless

* No EC2, no OS management
    
* AWS handles scaling, patching, availability
    

### ⚡ Event-driven

Lambda runs when an **event** happens, such as:

* HTTP request (via **API Gateway**)
    
* File upload to **S3**
    
* Message in **SQS**
    
* Database change in **DynamoDB**
    
* Scheduled time (cron via **EventBridge**)
    

### 💰 Pay-per-use

You pay for:

* Number of requests
    
* Execution time (milliseconds)
    
* Memory allocated
    

## Supported languages

AWS Lambda supports:

* **Node.js**
    
* **Python**
    
* **Java**
    
* **Go**
    
* **.NET**
    
* **Ruby**
    
* **Custom runtimes** (via Docker container)
