AWS Service: AWS Lambda
Question: What are the limitations and constraints of AWS Lambda, and how can they impact application design and deployment?
Answer:
There are some limitations and constraints to keep in mind when designing and deploying applications on AWS Lambda:
Memory and CPU limitations: AWS Lambda functions have memory and CPU limits which can impact the performance of the application. It’s important to optimize the code and resources used by the function to ensure it fits within these limits.
Execution time limits: AWS Lambda has a default maximum execution time limit of 15 minutes per function. This can be extended up to a maximum of 60 minutes, but it’s important to keep in mind that long-running functions can impact the scalability of the application.
Stateless environment: AWS Lambda functions are stateless, meaning they don’t store any information between executions. This can be challenging when working with stateful applications that require persistent data storage.
Cold start latency: When a new instance of a Lambda function is started, there can be a delay while the function is initialized. This can result in a higher latency for the first invocation of the function.
Limited network connectivity: AWS Lambda functions have limited network connectivity by default, which can impact the ability to access resources outside of AWS.
These limitations and constraints can impact the design and deployment of applications on AWS Lambda. It’s important to understand these limitations and design the application accordingly to ensure optimal performance and scalability.
