Service limits
The kinds of limits in Bulutistan Cloud, which ones you can raise, and where to find the quotas, product limits, and rate limits of each service.
Bulutistan Cloud limits what you can use in three ways. This page explains each kind and links to the pages that list the limits of each service.
Kinds of limits
| Kind | What it limits | Can you raise it? | Where to look |
|---|---|---|---|
| Quotas | How much of a resource you can use, for example instances, vCPUs, or volume storage: the subscription's quota and the project's allocation. | Yes. Request a higher quota for the subscription, and change the allocation of your projects. | Quotas |
| Product limits | Rules that each service enforces, for example the size range of a volume, the length of a name, or how many items one request can handle. | No. | The product's limits, in the table below. |
| Rate limits | How many requests you can send to the REST API in a period. | No. | Rate limiting |
What's available also depends on the region. See Regions.

The quota category is the group that the service's quotas belong to on the quota page. For the quotas in each category, see Quotas by category.
When you reach a limit
- A quota. A create request that would exceed the subscription's quota is refused with
409 Conflictand the codeQUOTA_EXCEEDED. The message names the quota and its ID. A create that would exceed the project's allocation fails in the cloud. Free up resources, move allocation between your projects, or request a higher limit. See Request a quota increase. - A product limit. The request is refused with an error that says what's wrong. Change the request. See Errors.
- A rate limit. The API answers
429 Too Many Requests. Wait for the time in theRetry-Afterheader, and send the request again.
