Service quotas
Your Cumulocity service includes so-called quotas. These quotas ensure that the service operates within the guarantees of the Cumulocity service-level agreements.
The following types of quotas are used:
- Hard: Services enforce this quota so that it cannot be exceeded.
- Soft: Services are guaranteed to operate within the specified service-level agreements as long as the quotas are not exceeded; however, exceeding the quotas may result in a degraded user experience and no assurance of meeting the service-level agreements.
The quotas listed here reflect the maximum values for the cloud subscriptions unless indicated otherwise. If you’re unsure whether a specific cloud service quota is sufficient for your use case, we recommend reaching out to your sales contact to discuss your needs and explore potential options. Some quotas may be adjustable through professional services, depending on the system dimensioning and your specific requirements. For Edge deployments, consult the Cumulocity Edge documentation.
