# Entri Power Overview

> Root-domain hosting — what Entri Power is and when to use it.

<Note>
  Entri Power's REST endpoints (`/power/*`) are served by the **Connect API gateway** at `https://api.goentri.com`, not by a separate Power host. There is no public Power-specific API host.
</Note>

Users care about a fully customizable product experience. That's where custom domains come in.

Domain-connected users become fully integrated with your product, resulting in better retention, and a better customer experience for their end users.

## About Entri Power (FAQ)

### How does Entri Power work?

Entri uses a reverse proxy with SSL termination. To illustrate the flow of data:

1. A client (such as a web browser) makes a request to your customer's domain.
2. That request goes through Entri's reverse proxy server and is passed along to your service.
3. Your service returns a response through the reverse proxy, which is then passed back to the client and renders your `applicationUrl`

### Why should you trust Entri as a reverse proxy?

Entri Power uses Amazon Web Services with [multi-region architecture](https://aws.amazon.com/solutions/implementations/multi-region-application-architecture/) to avoid single points of failure and minimize latency. We also leverage advanced distributed denial of service (DDOS) protection.

You can view Entri's uptime history on our [status page](https://status.entri.com/).

### What certificate authority does Entri use?

Entri is proud to use [Let's Encrypt](https://letsencrypt.org/) SSL certificates.

### How long on average does it take for an SSL certificate to go live?

On average, between 3-7 seconds.

### Can I use Entri Power with Cloudflare?

Yes you can.

### How many times can I provision the same domain?

You can re-power the same domain a maximum amount of 5 times during a 24 hours period.
