AWS IoT Greengrass endpoints and quotas - AWS General Reference

AWS IoT Greengrass 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.

Note

Legacy Verisign endpoints are currently supported for some Regions, but we recommend that you use ATS endpoints with ATS root CA certificates. For more information, see Server Authentication in the AWS IoT Developer Guide.

Legacy Verisign endpoints are currently supported for some Regions, but we recommend that you use ATS endpoints with ATS root CA certificates. For more information, see Server authentication in the AWS IoT Developer Guide.

Supported Legacy Endpoints

We recommend that you use the ATS endpoints in the preceding tables with ATS root CA certificates. For backward compatibility, AWS IoT Greengrass currently supports legacy Verisign endpoints in the following AWS Regions. This support is expected to end in the future. For more information, see Server authentication in the AWS IoT Developer Guide.

When using legacy Verisign endpoints, you must use Verisign root CA certificates.

Service Quotas

AWS IoT Greengrass Cloud API

Description Default
Maximum number of AWS IoT devices per AWS IoT Greengrass group. 2500
Maximum number of Lambda functions per group. 200
Maximum number of resources per Lambda function. 20
Maximum number of resources per group. 200

Maximum number of transactions per second (TPS) on the AWS IoT Greengrass APIs.

See TPS.

Maximum number of subscriptions per group. 10000
Maximum number of subscriptions that specify Cloud as the source per group. 50
Maximum length of a core thing name. 124 bytes of UTF-8 encoded characters.

TPS

The default quota for the maximum number of transactions per second on the AWS IoT Greengrass APIs depends on the API and the AWS Region where AWS IoT Greengrass is used.

For most APIs and supported AWS Regions, the default quota is 30. Exceptions are noted in the following tables.

API exceptions
API Default
CreateDeployment 20
AWS Region exceptions
AWS Region Default
China (Beijing) 10
AWS GovCloud (US-West) 10

This quota applies per account and per API. For example, in the US East (N. Virginia) Region, each account has a default quota of 30 TPS, which is the aggregate of all API operation requests. Each API (such as CreateGroupVersion or ListFunctionDefinitions) has a quota of 30 TPS. This includes control plane and data plane operations. Requests that exceed the account or API quotas are throttled. To request account and API quota increases, including quotas for specific APIs, contact your AWS Enterprise Support representative.

AWS IoT Greengrass Core

Description Default
Maximum number of routing table entries that specify Cloud as the source. 50 (matches AWS IoT subscription quota)
Maximum size of messages sent by an AWS IoT device. 128 KB (matches AWS IoT message size quota)
Maximum message queue size in the Greengrass core router. 2.5 MB
Maximum length of a topic string. 256 bytes of UTF-8 encoded characters.
Maximum number of forward slashes (/) in a topic or topic filter. 7
Minimum disk space needed to run the Greengrass Core software.

128 MB

400 MB when using OTA updates

Minimum RAM to run the Greengrass Core software.

128 MB

198 MB when using stream manager

The Greengrass Core software provides a service to detect the IP addresses of your Greengrass core devices. It sends this information to the AWS IoT Greengrass cloud service and allows AWS IoT devices to download the IP address of the Greengrass core they need to connect to. This feature should not be used in the following circumstances:

  • The IP address of a Greengrass core device changes frequently.

  • The Greengrass core device is not always available to AWS IoT devices in its group.

  • The Greengrass core has multiple IP addresses and an AWS IoT device is unable to reliably determine which address to use.

  • Sending IP addresses to the cloud raises security concerns.
