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 |

| 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. |
