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

Name Default Adjustable Description
Asynchronous payload Each supported Region: 256 Kilobytes No The maximum size of an incoming asynchronous invocation request.
Burst concurrency

us-east-1: 3,000

us-east-2: 1,000

us-west-2: 3,000

ap-northeast-1: 1,000

eu-central-1: 1,000

eu-west-1: 3,000

Each of the other supported Regions: 500

No The maximum immediate increase in function concurrency that can occur when your functions scale in response to a burst of traffic. After the initial burst, concurrency scales by 500 executions per minute up to your 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 Each supported Region: 250 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 memory maximum Each supported Region: 10,240 Megabytes No The maximum amount of memory that you can configure for a function.
Function memory minimum Each supported Region: 128 Megabytes No The minimum amount of memory that you can configure for a 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.
