| Feature | Description | CRDs | Aggregated API |
| ------- | ----------- | ---- | -------------- |
| Validation | Help users prevent errors and allow you to evolve your API independently of your clients. These features are most useful when there are many clients who can't all update at the same time. | Yes. Most validation can be specified in the CRD using [OpenAPI v3.0 validation](/docs/tasks/access-kubernetes-api/extend-api-custom-resource-definitions/#validation). Any other validations supported by addition of a [Validating Webhook](/docs/reference/access-authn-authz/admission-controllers/#validatingadmissionwebhook-alpha-in-1-8-beta-in-1-9). | Yes, arbitrary validation checks |
| Defaulting | See above | Yes, either via [OpenAPI v3.0 validation](/docs/tasks/access-kubernetes-api/extend-api-custom-resource-definitions/#defaulting) `default` keyword (alpha in 1.15), or via a [Mutating Webhook](/docs/reference/access-authn-authz/admission-controllers/#mutatingadmissionwebhook-beta-in-1-9) | Yes |

| Multi-versioning | Allows serving the same object through two API versions. Can help ease API changes like renaming fields. Less important if you control your client versions. | [Yes](/docs/tasks/access-kubernetes-api/custom-resources/custom-resource-definition-versioning) | Yes |
| Custom Storage | If you need storage with a different performance mode (for example, time-series database instead of key-value store) or isolation for security (for example, encryption secrets or different | No | Yes |
| Custom Business Logic | Perform arbitrary checks or actions when creating, reading, updating or deleting an object | Yes, using [Webhooks](/docs/reference/access-authn-authz/extensible-admission-controllers/#admission-webhooks). | Yes |

| Other Subresources | Add operations other than CRUD, such as "logs" or "exec". | No | Yes |
| strategic-merge-patch | The new endpoints support PATCH with `Content-Type: application/strategic-merge-patch+json`. Useful for updating objects that may be modified both locally, and by the server. For more information, see ["Update API Objects in Place Using kubectl patch"](/docs/tasks/run-application/update-api-object-kubectl-patch/) | No | Yes |
| Protocol Buffers | The new resource supports clients that want to use Protocol Buffers | No | Yes |
| OpenAPI Schema | Is there an OpenAPI (swagger) schema for the types that can be dynamically fetched from the server? Is the user protected from misspelling field names by ensuring only allowed fields are set? Are types enforced (in other words, don't put an `int` in a `string` field?) | Yes, based on the [OpenAPI v3.0 validation](/docs/tasks/access-kubernetes-api/extend-api-custom-resource-definitions/#validation) schema (beta in 1.15) | Yes |
