Amazon Simple Notification Service 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.

Soft

The following quotas vary by AWS Region. The messages per second quota is
based on the number of messages published to an Amazon SNS region, combining
Publish and PublishBatch API requests. You can
request a soft limit increase by opening a quota increase case in the Amazon Support Center.

For example, if your regional quota is 30,000 messages per second, there
are a few ways this quota can be reached:

• Using the Publish action at a rate of 30,000 API requests
  per second to publish 30,000 messages (one message per API
  request).

• Using the PublishBatch action at a rate of 3,000 API
  requests per second to publish 30,000 messages (10 messages per batch
  API request).

• Using the Publish action at a rate of 10,000 API requests
  per second to publish 10,000 messages (one message per API request) and
  the PublishBatch action at a rate of 2,000 API requests per
  second to publish 20,000 messages (10 messages per batch API request)
  for a total of 30,000 messages published per second.
