This document lists the quotas and system limits that apply to Service Extensions.
- Quotas specify the amount of a countable, shared resource that you can use. Quotas are defined by Google Cloud services such as Service Extensions.
- 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.
To adjust most quotas, use the Google Cloud console. For more information, see Request a quota adjustment.
The following quotas apply to Service Extensions. They can be increased on request.
| Quotas | Value | |
|---|---|---|
| Maximum number of global authorization extensions in a project | 100 | |
| Maximum number of global route extensions in a project | 100 | |
| Maximum number of global traffic extensions in a project | 100 | |
| Maximum number of route extensions per region in a project | 100 | |
| Maximum number of traffic extensions per region in a project | 100 | |
| Maximum number of plugins per project | 100 | |
| Cloud Load Balancing only: Maximum number of plugins attached to Application Load Balancers through traffic extensions per project, per location, and per load balancing scheme | 5 at any given point in time | |
| Cloud Load Balancing only: Maximum number of plugins attached to Application Load Balancers through route extensions per project, per location, and per load balancing scheme | 5 at any given point in time | |
Media CDN only: Maximum number of plugin resources attached to
Media CDN services through WasmAction
resources per project |
5 at any given point in time |
Limits
There are also system limits on Service Extensions resources. System limits can't be changed.
Service Extensions enforces the following usage limits:
| Usage limit | Value | |
|---|---|---|
| Maximum number of extension chains per attachment point | 5 | |
| Maximum number of plugins or callouts in a traffic extension chain | 3 | |
| Maximum number of plugins or callouts in a route extension chain | 1 | |
Maximum execution duration per request. The duration is the sum of the durations of all Proxy-Wasm callbacks
associated with the request. Plugins that exceed the limit are terminated,
which causes the associated request to return an HTTP |
1 ms | |
| Maximum size of a compiled plugin along with the plugin configuration data. | 5 MiB | |
Maximum size of the plugin configuration data
when provided directly (by using file upload in the Google Cloud console, the
--plugin-config or --plugin-config-file option
with the Cloud SDK, or the WasmPluginVersion.plugin_config_data
field with the REST API) and not by using Artifact Registry.

900 KiB | |
Maximum memory used by a plugin Plugins that exceed this memory are terminated, which causes the associated
request to return an HTTP |
16 MiB | |
Maximum log content emitted by a plugin per request Logs that exceed this limit are truncated. |

| Maximum number of versions per plugin | 100 |
