# Infrastructure

> Learn about Algolia's infrastructure

export const Application = () => <Tooltip tip="An Algolia application is a self-contained environment with its own indices, configuration, and API keys. Applications don't share data or settings with each other.">
    application
  </Tooltip>;

Algolia optimizes its infrastructure for fast and scalable search and indexing operations.
Depending on your subscription,
your Algolia <Application /> is hosted in one of these ways:

* [Dynamic scaling infrastructure](/doc/guides/scaling/infrastructure/dynamic/dynamic)
* [Classic infrastructure](/doc/guides/scaling/infrastructure/classic/servers-clusters)

## Monitoring

You can check the status of all Algolia's services on [https://status.algolia.com](https://status.algolia.com).
This can be useful to see if there are any incidents.

To specifically see the status of **your** Algolia cluster,
go to the Algolia dashboard:

1. On the left sidebar, select <Icon icon="chart-no-axes-column" /> **API Monitoring**.
2. Open the [Status](https://dashboard.algolia.com/monitoring/status) page.

To check the status and your cluster activity programmatically,
use the [Monitoring](/doc/rest-api/monitoring) and [Usage](/doc/rest-api/usage) APIs.

If you want to set up **capacity alerts** for your classic infrastructure,
see [Capacity alerts](/doc/guides/scaling/infrastructure/classic/capacity-alerts).
