This document lists the quotas and system limits that apply to Google Cloud Migration Center.
- Quotas specify the amount of a countable, shared resource that you can use. Quotas are defined by Google Cloud services such as Google Cloud Migration Center.
- System limits are fixed values that cannot be changed.
Google Cloud uses quotas to help ensure fairness and reduce spikes in resource use and availability. A quota restricts how much of a Google Cloud resource your Google Cloud project can use. Quotas apply to a range of resource types, including hardware, software, and network components. For example, quotas can restrict the number of API calls to a service, the number of load balancers used concurrently by your project, or the number of projects that you can create. Quotas protect the community of Google Cloud users by preventing the overloading of services. Quotas also help you to manage your own Google Cloud resources.
The Cloud Quotas system does the following:
- Monitors your consumption of Google Cloud products and services
- Restricts your consumption of those resources
- Provides a way to request changes to the quota value
In most cases, when you attempt to consume more of a resource than its quota allows, the system blocks access to the resource, and the task that you're trying to perform fails.
Quotas generally apply at the Google Cloud project level. Your use of a resource in one project doesn't affect your available quota in another project. Within a Google Cloud project, quotas are shared across all applications and IP addresses.
There are also system limits on Migration Center resources. System limits can't be changed.
Quotas
The following table highlights important global quotas for each project. For other quotas, see the Quotas page in the Google Cloud console.
| Item | Quota | Notes |
|---|---|---|
| Number of API requests per user, per minute | Quotas | The maximum number of API requests that an Migration Center user can make to the Google Cloud Migration Center API within a one-minute time period. |
The preceding quota is only for API requests.
Resources limits
The following table highlights the resource limits that Migration Center enforces.
| Usage limit | Value | Notes |
|---|---|---|
| Assets | 100,000 | When you reach this limit, you can no longer perform manual import jobs. Updates on existing assets coming from the discovery client might still work. If you believe that your use case requires more assets than allowed by this limit, open a customer support ticket before reaching this limit. |
