AWS Lambda endpoints and quotas - AWS General Reference

AWS Lambda endpoints and quotas

The following are the service endpoints and service quotas for this service. To connect programmatically to an AWS service, you use an endpoint. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. For more information, see AWS service endpoints. Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see AWS service quotas.

Service quotas

Important

New AWS accounts have reduced concurrency and memory quotas. AWS raises these quotas automatically based on your usage. You can also request a quota increase.

Name Default Adjustable Description
Asynchronous payload Each supported Region: 256 Kilobytes No The maximum size of an incoming asynchronous invocation request.
Concurrency scaling rate Each supported Region: 1,000 No The maximum immediate increase in function concurrency that can occur in response to an increase in traffic or execution duration. Every 10 seconds, each synchronously invoked Lambda function can scale by an additional 1,000 concurrent executions until the total concurrency across your functions in a Region reaches the account concurrency limit.
Concurrent executions Each supported Region: 1,000 Yes The maximum number of events that functions can process simultaneously in the current Region.
Deployment package size (console editor) Each supported Region: 3 Megabytes No The maximum size of a deployment package or layer archive when you upload it through the console editor. Upload larger files with Amazon S3.
Deployment package size (direct upload) Each supported Region: 50 Megabytes No The maximum size of a deployment package or layer archive when you upload it directly to Lambda. Upload larger files with Amazon S3.
Deployment package size (unzipped) Each supported Region: 250 Megabytes No The maximum size of the contents of a deployment package or layer archive when its unzipped.
Elastic network interfaces per VPC

af-south-1: 250

ap-east-1: 250

ap-southeast-3: 250

eu-north-1: 250

eu-south-1: 250

me-south-1: 250

Each of the other supported Regions: 500

Yes The maximum number of network interfaces that Lambda creates for a VPC with functions attached. Lambda creates a network interface for each combination of subnet and security group that functions connect to.
Environment variable size Each supported Region: 4 Kilobytes No The maximum combined size of environment variables that are configured on a function.
File descriptors Each supported Region: 1,024 No The maximum number of file descriptors that a function can have open.
Function and layer storage Each supported Region: 75 Gigabytes Yes The amount of storage thats available for deployment packages and layer archives in the current Region.
Function layers Each supported Region: 5 No The maximum number of layers that you can add to your function.
Function resource-based policy Each supported Region: 20 Kilobytes No The maximum combined size of resource-based policies that are configured on a function.
Function timeout Each supported Region: 900 No The maximum timeout that you can configure for a function.
Processes and threads Each supported Region: 1,024 No The maximum combined number of processes and threads that a function can have open.
Rate of GetFunction API requests Each supported Region: 100 No The maximum number of GetFunction API requests per second.
Rate of GetPolicy API requests Each supported Region: 15 No The maximum number of GetPolicy API requests per second.
Rate of control plane API requests (excludes invocation, GetFunction, and GetPolicy requests) Each supported Region: 15 No The maximum number of API requests per second (excluding invocation, GetFunction, and GetPolicy requests).
Synchronous payload Each supported Region: 6 Megabytes No The maximum size of an incoming synchronous invocation request or outgoing response.
Temporary storage Each supported Region: 512 Megabytes No The amount of storage space thats available to a function in the /tmp directory.
Test events (console editor) Each supported Region: 10 No The maximum amount of test events for a function through the console editor.
