AWS Application Discovery Service Limits

Application Discovery Service has the following limits per account:

  • Applications – 1,000 applications per account. If you reach this limit, and want to import new applications, you can delete existing applications with the DeleteApplications API action. For more information, see DeleteApplications in the Application Discovery Service API Reference.

Application Discovery Service has the following limits for discovery:

  • Import – Each import file can have a maximum file size of 10 MB.

  • Agentless discovery – The service limits you to 10 GB of data per day. If you reach this limit, the service doesn't process any more data for that day. If you frequently reach this limit, contact AWS Support about extending the limit.

  • Agent-based discovery – currently, the following limits are enforced:

    • 1,000 active agents — agents that are collecting and sending data to Application Discovery Service in the cloud.

    • 10,000 inactive agents — agents that are responsive but not collecting data.

    • 10 GB of data per day — collected by all agents associated with a given AWS account.

    • 90 days of data storage — after which the data is purged.
