# scale section

> Scale a squid horizontally and vertically using the manifest scale section — replicas, processor profiles, GraphQL profiles, and addon resources.

The `scale:` section of the [deployment manifest](/en/cloud/reference/manifest) allows allocating additional computing resources for the squid add-ons and services. This option is only available for paid squids deployed in [professional organizations](/en/cloud/resources/organizations/#professional-organizations).

<Info>
  Visit the [Pricing page](/en/cloud/pricing) and/or our [costs calculator](https://subsquid.io/subsquid-cloud#calculator) if you're looking for an estimate.
</Info>

The manifest supports the following scaling options:

## `dedicated:`

Default: `dedicate
d: true`.

When a dedicated profile is used, the resources that the squid requests are reserved in advance. **This is the new/current default** and is the recommended profile for production squids. Squid deployment must be dedicated to be a subject of [SQD Cloud SLA](/en/cloud/pricing).

By setting `dedicated: false` you can request for your deployment to be *collocated* - that is, share resources with other deployments. The allocation of full resources is not guaranteed for collocated squids.

All playground squids must use the collocated profile, that is, explicitly specify `dedicated: false`.

## `addons:`

### `postgres:`

See [Postgres add-on](/en/cloud/reference/pg) for details.

## `services:`

### `api:`

| `replicas` | The number of gateway replicas. The API requests are distributed between the replicas in the round-robin fashion |                          Number                         |      `1`      | Optional |

The profile specifications for API service replicas are as follows:
