### What it is and how it is billed

<details>

<summary>What is a Plenit server?</summary>

It is a virtual machine, Windows or Linux, that runs on our infrastructure and that you deploy, scale, and manage from the panel. For your customer it works like a dedicated server; for you, like a resource you activate in minutes and pay for as you use it, without buying or maintaining hardware. More in [What is a Server?](/docs-en/productos/servers/concepts/what-it-is.md)

</details>

<details>

<summary>How is it billed?</summary>

By consumption, in €/month or €/hour and with no commitment. Servers are grouped into subscriptions, which are your unit of organization and billing; within a subscription you deploy as many servers as you need.

</details>

<details>

<summary>What do you operate and what do I operate?</summary>

We operate the foundation: the host and virtualization, storage, infrastructure network controls, and the data center. You operate your server: the data, accounts and identities, the operating system, the applications, the firewall rules, and control of your backups. On Layer 2 networks or with Direct IP, you also manage the entire network stack with your own appliance.

</details>

<details>

<summary>In which data centers and with which certifications?</summary>

The infrastructure is our own and certified (ISO 27001 and ENS, among others). Details on regions, availability zones, and certifications are in Details.

</details>

### Size and images

<details>

<summary>How do I choose the server size?</summary>

You decide CPU, RAM, and disk according to your customer's workload, from 1 vCPU / 1 GB to 32 vCPU / 128 GB. The recommendation is to start sized to what the workload needs today, not to overprovision: you pay for consumption and can scale later. You have a table of starting points by workload type in [Size your server.](/docs-en/productos/servers/concepts/size-cpu-ram-disk.md)

</details>

<details>

<summary>Can I expand resources later?</summary>

Yes, you can add CPU, RAM, or disk on the fly, without reinstalling or migrating. Expanding the disk does not stop the server; reducing it is more delicate and should be planned. The step-by-step guide is in [How-to.](/docs-en/productos/servers/how-to.md)

</details>

<details>

<summary>Which operating systems can I deploy?</summary>

Windows Server and the main Linux distributions (Ubuntu, Debian, AlmaLinux, Rocky Linux, Oracle Linux, among others). Windows fits ERP and Windows business software; Linux fits web, databases, containers, and appliances. The full catalog of versions is in Details, and the criteria for choosing it is in [Images and applications.](/docs-en/productos/servers/concepts/images-and-applications.md)

</details>

<details>

<summary>Can I reuse a configuration across multiple customers?</summary>

Yes. You set up a server the way you like it, turn it into your own image, and deploy as many identical copies as you need. You can save up to 12 images per subscription.

</details>

<details>

<summary>What is in the Marketplace?</summary>

Preconfigured appliances and software ready to deploy: 3CX (VoIP PBX), FortiGate VM and FireboxV (firewalls you operate as VNF), and Pandora FMS (monitoring), among others.

</details>

### Networks and security

<details>

<summary>What network types do I have?</summary>

Four: Standard (a managed Virtual Router with DNS, DHCP, gateway, NAT, and firewall, the usual case), VPC (multilevel and the only one with site-to-site IPSec VPN), Layer 2 (pure Layer 2, where you manage the entire stack with your VNF), and Direct IP (public IP without NAT). The criteria for choosing is in [Server networking.](/docs-en/productos/servers/concepts/networks.md)

</details>

<details>

<summary>Can I use my own firewall?</summary>

Yes, with a VNF: a network appliance that you deploy and operate yourself (FortiGate VM or FireboxV, from the Marketplace). The self-managed perimeter pattern combines Direct IP as WAN, your VNF as firewall, and a Layer 2 network as LAN. In Layer 2 and Direct IP, you define and maintain the firewall rules yourself.

</details>

<details>

<summary>Can I connect the cloud with the customer's office?</summary>

Yes, on a VPC network you can set up site-to-site IPSec tunnels to connect the cloud with headquarters, and remote access VPN for users. Each gateway supports up to 10 VPNs, with IKEv1, IKEv2, or Auto, and split tunneling when you need it. The step-by-step configuration is in [How-to.](/docs-en/productos/servers/how-to.md)

</details>

<details>

<summary>How do I distribute the load across multiple servers?</summary>

With a load balancer on a Standard network. In addition to improving performance, it gives you a way to keep the service running while one machine is under maintenance.

</details>

### Backups

<details>

<summary>Do the servers include backup?</summary>

Yes, each server includes automatic scheduled backups: every hour, every day, and every week. They are configured by disk and by server, and retention is configurable. More in[ Backup and data protection.](/docs-en/productos/servers/concepts/backup-and-data-protection.md)

</details>

<details>

<summary>What is the difference between a backup and a snapshot?</summary>

The backup is automatic and saves versions of your disks according to the schedule. The snapshot is a manual instant capture of the entire machine that you take at a specific time, for example just before a risky change, so you can roll back if something goes wrong.

</details>

<details>

<summary>Do backups protect me against ransomware?</summary>

Backups are stored as read-only: once created, they cannot be modified or encrypted from the server. If ransomware reaches the machine, it cannot touch the backups and you have a place to restore from.

</details>

<details>

<summary>Does backup guarantee that the service stays up?</summary>

No. Backup is used to recover data and state, not to keep the service available if a machine goes down. That is continuity design, with multiple servers and the right architecture. Backup and continuity complement each other; they do not replace each other.

</details>
