Final answer:
AWS Lambda has code restrictions including a 15-minute execution time, deployment package size limits, memory allocation constraints, concurrent execution limits, preset runtime environments, and 512 MB of temporary disk space.
Step-by-step explanation:
What restrictions apply to AWS Lambda function code?
AWS Lambda is a serverless computing service that allows users to run code without provisioning or managing servers. However, there are several restrictions applied to the Lambda function code to ensure security, performance, and resource utilization:
- Execution Time: The maximum execution duration per request is 15 minutes.
- Deployment Package Size: The deployment package size is limited, including all the dependencies, to 50 MB when zipped and up to 250 MB when unzipped.
- Memory Allocation: The amount of memory you can allocate to a function is between 128 MB and 10 GB.
- Concurrent Executions: AWS imposes a limit on the number of concurrent executions across all functions in a given region.
- Runtime Environment: The function code must be written in one of the supported programming languages.
- Temporary Disk Space: AWS Lambda provides 512 MB of temporary disk space (/tmp directory).
These constraints ensure that the Lambda functions perform optimally within the AWS environment and adhere to the platform's operational bounds.
