# Hosting & Tech Specs

Below are the hosting options (Zuar hosted or self hosted) and system requirements for Mitto.

## Hosting

### Zuar Hosted Mitto
Sever hosted by Zuar in AWS or Digital Ocean. Specifications about your deployment can be found on 
the Mitto settings page.

Two factor authentication:
- Username and password - Mitto UI and database
- IP Whitelist - Zuar whitelists users' IP addresses

### Self Hosted Mitto
Server hosted by the customer in their public cloud (AWS, Azure, GCP, etc), private cloud, or on-premise.

Zuar needs network access to the Mitto instance. Mitto itself needs network access to the destination database (if not using Mitto's internal PostgreSQL):

- HTTP/HTTPS (80, 443)
- PostgreSQL (5432) (and destination database's port)
- SSH (22) - Zuar needs root access to the Ubuntu box to install, upgrade, and support Mitto.
- FTP (20/21) *Optional*
- Passive FTP (40000-40100) *Optional*

In addition, if you output to a db on another server, you might consider opening these same ports on that server and in any firewalls between your Mitto instance and that server.

Lastly, after the installation is complete, a hostname/domain name and SSL certificate will need to be assigned to the Mitto instance.

1. Once the desired hostname/domain name has been acquired, create an ANAME record that points to Mitto's IP.
1. Create an SSL certificate and add it the Mitto deployment. *Contact Zuar support for additional guidance on how to add or renew the certificate if necessary.*

## Tech Specs

.. NOTE::
   
   Mitto can be scaled according to data volumes and use cases.

Please provide a clean server without any other applications installed. Mitto will install the applications it needs to run. Root access is required for installation.

### Server Minimum Requirements

| Component | Value |
|---|------- |
| Operating System  | Ubuntu 22.04 |
| CPU  | 2 Core |
| Memory | 4 GB |
| Disk | 80 GB |

Amazon AWS EC2 equivalent: `t2.medium`

### Server Recommended Requirements

| Component | Value |
|---|------- |
| Operating System  | Ubuntu 22.04 |
| CPU  | 4 Core |
| Memory | 8 GB |
| Disk | 200 GB |

Amazon AWS EC2 equivalent: `m4.large`

### Database
Mitto's internal database is PostgreSQL 13.2.

A standard Mitto deployment uses this PostgreSQL database as the analytics database for the customer.

Mitto can pipe data into the customer's desired database technology (cloud or on-premise). If the customer wants Zuar to host a different database technology than the internal PostgreSQL database, the cost is added to the Mitto subscription.
