### Infrastructure
[[#^Top|TOP]]
&emsp;

This section sums up required infrastructure for self-hosting online services.

&emsp;

#### Hardware

An option is to look at a **Virtual Private Server** (VPS) service. This also solves the issue of the access to the Internet, that is more and more advised to not come from a home connection.

> [!tip] 
> A good aggregator for low-cost VPS [here](https://lowendbox.com)

Otherwise, **physical hardware** include:

| Product | Type | Price range
|--------|-------|-----------
|<p style="color:green">**Synology (DS218/220+)**</p> | NAS | £250/300
|<p style="color:cyan">**Dell Poweredge Tower Server T30**</p> | Server | £300/400
|<p style="color:maroon">**HP Z420**</p> | Workstation | £400

==WIP==

&emsp;

#### OS & Applications
[[#^Top|TOP]]
**Linux** is the most common OS for servers. **Ubuntu**, **Debian** or **CentOS** the most common distributions.
**MacOS** would require a Virtual Machine to run properly.

&emsp;

#### Internet connection

More and more literature point that a home Internet connection may not be the most appropriate way for a server to connect to the Internet. ISPs limit traffic to manage bandwidth and comply to legislations.

&emsp;

#### Domain
[[#^Top|TOP]]

> [!info]  Privacy-friendly domain manager
> [Njalla](https://njal.la/)

Domain management is important for several reasons: email and email routine can only be defined once per domain. As such, email services (self-hosting, email aliasing) need to be run on separate domains.

For self-hosting, the folllowing domain will be used: **mfxm.fr**

> [!warning] 
> Sub-domains to be defined with **webhost**.

&emsp;

#### Security

Security is paramount at the points of connection to the server. SSH protocols are secured but csn be intercepted. Two different ways of protection can be implemented:

&emsp;

##### RSA Key
[[#^Top|TOP]]

> [!info]  Documentation
> [SSH Key Tutorial](https://www.linode.com/docs/guides/use-public-key-authentication-with-ssh/)
[SSH Key Tutorial 2](https://upcloud.com/community/tutorials/use-ssh-keys-authentication/)

All documentation to implement such control can be found [[VPS Console Dialogue#Securing Server access|here]].

&emsp;

##### VPN

> [!info]  Documentation
> [SSH VPN](https://openvpn.net/community-resources/how-to/)

Not tested.

&emsp;

##### Other security considerations

Additional measures can be found below and are in majority described [[VPS Console Dialogue#Editing the Server's SSH config|here]].

> [!info]  Documentation
> [Securing SSH](https://www.redhat.com/sysadmin/eight-ways-secure-ssh)

&emsp;

#### Continuity & backups
[[#^Top|TOP]]

> [!info]  Documentation
> [Local backup](https://blog.ssdnodes.com/blog/vps-backups-simple-overthinking/)
[Hot Copy](https://programmerbear.com/how-to-backup-your-entire-server-or-vps-while-its-running-using-linux-hot-copy/)

Backups are managed through the **tar** command and dispatched over the network with **rclone**. Instructions can be found [[VPS Console Dialogue#Backing up a server|here]].

&emsp;

#### Server Monitoring
[[#^Top|TOP]]
> [!info]  Documentation
> [Monit](https://mmonit.com/)
[Performance Co-Pilot](https://pcp.io/)
[Nagios](https://nagios.org)

Monitoring is implemented through a free and open-source tool called [[Configuring Monit|monit]].

Other Apps include:

### Running multiple services on the same hardware
[[#^Top|TOP]]
&emsp;

> [!tip]  Considerations to start
> [Tutorial](https://cyberhost.uk/getting-started/)
[Caddy tutorial](https://cyberhost.uk/caddy-setup/)
[Nginx Proxy Manager tutorial](https://cyberhost.uk/npm-setup/)

In essence, to run multiple services on the same hardware, a few basic steps need to be taken to ensure that each service runs properly.

&emsp;

| Consideration | Tool | Description
|---------------|------|------------
| <p style="color:cyan">**Compartimentalise services into containers**</p> | **[[Configuring Docker\|docker]]** | Creates containers that can be run independently
| <p style="color:turquoise">**Simplify docker commands**</p> | **docker-compose** | Enables to create 'script' for docker commands
| <p style="color:teal">**Route internet traffic appropriately**</p> | reverse proxy: **nginx**, **[[Configuring Caddy\|caddy]]** | Enables to route addresses to the appropriate containers and manage SSL certificates (and https forcing)

### Self-hosted services
[[#^Top|TOP]]
&emsp;

A list of FOSS services can be found [here](https://github.com/awesome-selfhosted/awesome-selfhosted)


| Service | OS | Technical reqs |  Description
|--------|----|----------------|--
<span style="color:orange">**Email service**</span> | Linux |  2GB RAM recommended | self-host an [[#Email service]]
<p style="color:green">**Email aliases**</p> | Linux  | 2GB RAM; ports: 22, 25, 80, 443  | an [[#Email alias service\|alias service]] like [SimpleLogin](https://simplelogin.io)
**[[Nextcloud]]** | Linux | 500M RAM; MySQL & SQL Lite; PHP 8.0; Apache 2.4 with PHP or nginx with PHP |  [[#Personal cloud syncing]] instance
<p style="color:purple">**Instant Message**</p> | Linux | 2/4GB RAM; ports & other extensions |  [[Element]] instance for [[#Instant Messenging]]
<p style="color:violet">**VPN**</p> | Linux | 500MB RAM | Host a private [[#VPN]]

&emsp;

#### Email service
[[#^Top|TOP]]
Email service can be fully built but has many components to it: server, database, imap, caldav, carddav, DNS specificities, spam whitelisting as well as security (server access & spam filtering). It can therefore be tideous to build an email service from scratch. Pre-packaged solitions exist to manage all components:
1. [IRedMail](https://www.iredmail.org/)
2. [Mail-in-a-Box](https://mailinabox.email/)
3. [Docker-mailserver](https://hub.docker.com/r/tvial/docker-mailserver/) which is command-line-only and to be built more extensively than the two other alternatives
