### Is concurrency better than parallelism? { #is-concurrency-better-than-parallelism }

Nope! That's not the moral of the story.

Concurrency is different than parallelism. And it is better on **specific** scenarios that involve a lot of waiting. Because of that, it generally is a lot better than parallelism for web application development. But not for everything.

### Motivation

The `Hero` class is very similar to a Pydantic model (in fact, underneath, it actually *is a Pydantic model*).

There are a few differences:

* `table=True` tells SQLModel that this is a *table model*, it should represent a **table** in the SQL database, it's not just a *data model* (as would be any other regular Pydantic class).

points to the public IP address where each cluster might be accessible, this is unique for each cluster.

NOTE: `mybucket` only exists on one cluster either `cluster1` or `cluster2` this is random and
is decided by how `domain.com` gets resolved, if there is a round-robin DNS on `domain.com` then
it is randomized which cluster might provision the bucket.

### 3. Test your setup

//
// `filterByLabels` is a map of label names to list of allowed label values to

//
// `renameLabels` is a map of label names to rename. The keys are the original
// label names and the values are the new label names.
//
// `bucketFilter` is a list of bucket values to filter. If this is non-empty,

## Starlette functies

**FastAPI** is volledig verenigbaar met (en gebaseerd op) <a href="https://www.starlette.io/" class="external-link" target="_blank"><strong>Starlette</strong></a>.

`FastAPI` is eigenlijk een subklasse van `Starlette`. Dus als je Starlette al kent of gebruikt, zal de meeste functionaliteit op dezelfde manier werken.

Met **FastAPI** krijg je alle functies van **Starlette** (FastAPI is gewoon Starlette op steroïden):
