Frequently Asked Questions: VPS

What is a VPS used for?

A VPS is a virtual private server used to host websites - including online shops, written content, media content, and/or software applications, primarily web applications - portals, extranets, collaborative solutions, wiki, CRM, etc.

In contrast to a web hosting plan, a VPS can isolate multiple applications within a single virtual machine that's dedicated to one customer. This virtual machine shares physical resources (infrastructures) with other virtual machines, but some of these resources are dedicated to it.

Who can use a VPS?

Anybody with minimum technical skills can use a VPS. The OVH guides will help you find the answers to all your technical questions.

Only minimal management skills are required. OVH is increasingly offering pre-installed versions and versions equipped with tools and applications, making it easier to manage these containers.

How much is a VPS?

This depends on the power you choose and the criticality of the hosted environment.

aggressive pricing

A VPS is the logical next step after a web hosting plan.

A VPS gives you more freedom and you get root access which allows you to: access your Apache config, change PHP.ini settings and variables, install an SSL certificate and any type of software. In short, you gain freedom without the responsibility of a physical dedicated server.

On a shared server, however, you don't control performance, so you rely on the performance provided by the shared platform. With a VPS, you need to choose a configuration that's suitable for your application now, and then adjust it to cater to your application's growth.

How to choose the best VPS?

Should I choose a VPS or a dedicated server?

VPS models are perfect for hosting the majority of controlled-size web projects.

A dedicated server is for you if you want to: have total control over the environment, build more complex architectures and solutions, configure more network components, deploy complex non-web-based solutions and/or have access to additional dedicated hardware components, e.g. a load balancer or firewall.
Customers who need more complex and flexible infrastructures to handle an increasing number of visitors should start off with a VPS Cloud. They can then scale up to an OVH dedicated server or a Cloud solution.

How do I upgrade my VPS?

From the Control Panel or the OVH VPS API, you can upgrade your VPS to get more resources permanently.

How do I configure my VPS?

It depends on the OS installed on your VPS and the VPS's configuration.

For basic configurations: via a remote desktop (particularly on Windows), in SSH command line on Linux, via a web-based control panel (Plesk, Cpanel, OVH Control Panel); via the solutions deployed on the server (e.g. CMS).
For more advanced configurations, VPS upgrades, the configuration of passwords and rights for the above actions: via the OVH RESTful API or the OVH Control Panel.

How long does it take to activate a VPS?

Your VPS will be active and available a few minutes after your payment has been processed. This process may take longer in the event that we need to manually validate your payment details as part of our anti-fraud policy.

Where are the VPSs located?

The servers are hosted in our data centers.

All of our ranges are hosted in North America (Beauharnois, Quebec).

How many VPSs are installed on one server?

It depends on the capacity of the server and the size of the VPS; but an OVH vHost (clusters of several dozens of very large, fully redundant servers) can host several thousand VPSs.

It's very important to us that each VPS runs smoothly. This is why we're committed to offer you guaranteed resources.

Can I host adult content on a VPS?

As long as the content is legal and the website complies with the rules of an adult website, e.g. access to minors is prohibited, you can absolutely host adult content on your VPS.

Additionally, OVH informs the customer of their responsibility for their website content when they accept the OVH VPS contract (when they place their order).

How do I migrate the content from a web hosting plan to a VPS?

It's down to you to migrate your data and applications on to the VPS and to reconfigure the DNS zone.

How do I migrate the content from one VPS to another?

When you upgrade your VPS, the contents will be migrated automatically without you having to do anything. OVH will ensure continuity of service. When you upgrade a VPS Cloud, you can also choose to expand your partition or create an additional one. You will receive an email after the upgrade containing all the details.

Take note that you can only upgrade to a VPS in the same range as your current VPS (e.g. VPS Cloud 1 to VPS Cloud 2). To upgrade to a different range, you will need to order a new VPS from scratch.

Can I partition a VPS?

Yes, the VPS can be partitioned and you can host multiple sites or projects for multiple clients (by allocating a customizable volume to indiviual private spaces).

This is your server space, and you can organize it as you see fit.

Installing a multi-site control panel may help to simplify these actions. If you choose a VPS Cloud, you can get an Odin Plesk Panel licence to host up to 10 sites on your virtual server at no extra cost.

What is the Control Panel used for?

You can manage the VPS via the Control Panel. You can restart it, buy additional services, monitor your VPS, etc.

You can reinstall your server at any time by choosing one of the many operating systems available.

What is the OVH RESTful API used for?

The OVH RESTful API complements the Control Panel. It allows you to reboot, reinstall a different OS, buy additional services, upgrade, etc.

Does the VPS have a dedicated IP address?

Every VPS comes with a dedicated public IPv4 address.

You can also add up to 16 additional geolocated IPv4 addresses to your VPS (see the OVH VPS additional services).

What is the VPS SLA?

The VPS platform is proven to be stable and highly available. When you rent one of our virtual private servers, we guarantee the continunity of your business activity.

In the event that we do not fulfil our commitment, we will undertake to reimburse 5% of the monthly price per hour of delay, up to a maximum of 100% of the monthly amount for the product.

This SLA only applies to models in the VPS Cloud series.

What is the OVH rescue mode used for?

You can always connect to your VPS Cloud, even in the worst-case scenario, and even if the bug is located on your system disk.

Rescue mode allows you to boot from a system operating with reduced functionalities, which isn't located on your local disk. You can therefore run all repair operations you need to, and then restart your server normally.

What is KVM access?

This mode allows you to access the BIOS of your VPS via a secure connection. This is ideal in the event of an issue with your VPS or for managing your server.

How do I configure my VPS's DNS?

Log in to the Control Panel to enter the DNS zone.

If you use Linux, you can configure the DNS zone using a command line; in certain cases, you will have a graphical interface.

How can I change my VPS's OS?

You can change your VPS's OS anytime you want via the OVH RESTful API or Control Panel.

This feature is totally free-of-charge. For VPS Cloud models, you can also choose to reinstall Windows, or migrate from Linux to Windows (as an option).

Make sure you back up your data before you reinstall your server.

Are domain names or email services included with a VPS?

No but you can link a domain name to your VPS by following the procedure outlined in this guide:

How do I upgrade my VPS?

You can upgrade your VPS to a more powerful server within the same series at anytime via the Control Panel.
Your entire system (OS, software, settings) is saved and you only need to make one simple change on your VPS's hard drive. The operation is performed in a few minutes automatically, and is practically invisible to your end-users.

Lastly, the months that remain on your current VPS will be automatically transferred over to your new model, on a pro-rata basis.

What usage is allowed on VPS? Will it be shut down if I use too many resources?

You are free to use your virtual machine as you wish and to install on it the software of your choice, subject to the legal limitations described in our general and special terms and conditions. When sharing a physical host, every user has a quota for each resource - CPU, RAM, drives, etc.

In compliance with our general conditions, we reserve the right to put a VPS in quarantine if used in a way that poses a threat to the stability of the infrastructure. Intensive and continuous usage of the CPU on a VPS Classic, for example, could trigger this process.

Can I move my VPS from one OVH data center to another (for example from a French one to a Polish one)?

This feature is not currently available. You cannot migrate or "copy" a VPS across to another data center. You can buy a new VPS in the new location and manually transfer your data. However your new VPS will have different IP addresses.
