AWS Lambda Function Limitations: A Comprehensive Guide

Lambda function limitations: Knowledge of this is important as it helps you understand what AWS Lambda cannot do, therefore influencing decision making when designing architectural solutions using AWS services.

What are Lambda Function Limitations?
AWS Lambda is a compute service that allows you to run code without managing servers. However, it comes with certain limitations, such as the maximum execution time, deployment package size, disk capacity (/tmp) per execution environment, etc.

How it Works?
When you run your application in AWS Lambda, it runs within certain configured limits. The service automatically scales the application in response to the incoming request traffic, however, within the set limits.

Answering Questions Regarding Lambda Function Limitations in an Exam:
To successfully answer the questions, focus on understanding the problem statement and the function's requirements. Identify if there are limitations such as 'execution time limit of 15 minutes' or 'concurrency limit of 1000' that might affect the solution's feasibility.

Exam Tips:
Remember the key limits of AWS Lambda - Execution time: maximum of 15 minutes, Memory allocation: 128 MB to 10,240 MB, /tmp directory storage: 512 MB, Deployment package (unzipped): 250 MB, Deployment package (zipped, including layers): 50 MB, Concurrency: 1,000 (can be increased upon request).
