Public Cloud

Commercial questions

What is the difference between public and private clouds?

OVH offers a public cloud offering, called Public Cloud, as well as a private cloud offering, called Private Cloud.

Public Cloud provides you with a full range of cloud resources (computing, storage, network) and orchestration tools. The latter can provide a containerization platform, amongst other things. Cloud services are operated on OpenStack-based shared infrastructures, which provide a large, instantaneous uplift capability. The services are billed on a daily or hourly basis, with a granularity that makes it easy to manage your budget.

Private Cloud, as a dedicated cloud solution, also provides an additional level of isolation: no-one else accesses the servers you are using to deploy your solutions. All resources are virtualized with VMware software. This gives you control over the infrastructure, as the cluster administrator.

How can I start using Public Cloud?

Make your purchase via the OVH Control Panel You just need to create a Public Cloud project, then launch a resource from the services available in the left menu. Billing takes place at the end of the month, using the payment method selected when the project was created.

How do I deploy a Public Cloud project?

A Public Cloud project is a group of cloud resources that are part of the same set. This segmentation can be used to separate your organization’s various projects, or to separate test and production environments. Each project also benefits from administrative isolation, with its own user management and dedicated billing.

Which payment methods do you accept?

OVHcloud accepts the following payment methods for Public Cloud: Visa®, Mastercard® and American Express®.

How does Public Cloud billing work?

When you create your very first public cloud project, you are will be prompted to enter a payment method. Your card will be charged $30.00 USD which will be used as a credit towards any compute and storage subscriptions and consumption charges you incur. Upon depletion of the credit, your default payment method will be used to cover the remaining recurring or consumption charges. You may cancel your subscriptions at any time from the OVH Manager. Any unused credit will be forfeited upon cancellation.

You can find additional information on US Public Cloud billing here.

Does Public Cloud invoice incoming and outgoing traffic from instances?

Inbound public traffic, as well as inbound and outbound private traffic (i.e. the vRack), are unlimited and free across all our Public Cloud regions.

Outbound public traffic is also free and unlimited.

OVH is committed to the following service levels:

  • Guaranteed Resource instances (CPU, RAM, General Purpose): Monthly availability rate of 99.999%
  • Sandbox instances: 99.95% monthly availability rate

In the event of our Support Team experiencing a loss of connectivity (excluding scheduled maintenance), 0.5% per minute of downtime will be reimbursed up to 50% of your instance-related consumption for the month concerned.

For more information, please consult the general Terms & Conditions.

What SLAs do you offer for Object Storage?

OVH is committed to the following service levels:

  • Object Storage containers: 99.9% monthly availability
  • 100% monthly data resilience rate

In the event of our Support Team experiencing a loss of connectivity (excluding scheduled maintenance), a 0.5% compensation per minute of downtime is earned up to 100% of your consumption related to Object Storage containers.
If the data resilience rate is not met, 100% of your consumption related to Object Storage containers will be compensated.

For more information, please consult the general Terms & Conditions.

 

Technical product questions

What bandwidth do you offer on the public network of instances?

OVH guarantees 250 Mbps of bandwidth for most instances with guaranteed resources of up to four vCores, then 500 Mbps for instances above that. Sandbox instances have bandwidth of up to 100 Mbps.

What disk performance do you offer on instances?

OVH guarantees up to 500 IOPS for Sandbox instances, and up to 1000 IOps for other instances. Additional disks have a performance level of up to 250 IOPS for Classic disks and up to 3,000 IOps for High Speed disks.

How do I add or remove instances?

All instances can be upscaled to more powerful instances from the same range. It is also possible to downscale an instance to a less powerful model, if it was launched with the flex option. This imposes a 50 GB disk size for all models and enables both up- and downscaling.

In both cases, this will involve rebooting.

Are Public Cloud instances compatible with cloud-init?

Yes. Cloud images provided by OVH include cloud-init scripts that allow you to customise instances when you launch them. The infrastructure provides instance customisation information via a metadata server, which cloud-init contacts directly.

Which regions is Public Cloud available in?

Currently, our Vint Hill (East Coast) Data Center is ready to host your Public Cloud services. 

Is it possible to back up my Public Cloud servers?

You can create Backup instances of your servers at any time, with no limitations. These backups are stored and invoiced as images in Private Image Catalog. You can download them from the OVH infrastructure, or from other projects, using the OpenStack APIs.

Can I use Windows licenses on Public Cloud instances?

Yes. You can choose to launch a Windows instance via the OVH Control Panel, or install the Windows image of your choice via your Horizon interface.

In order to keep the rates for our Windows instances simple and easy to read, the price differences between them and our Linux instances are shown on our product pages. Just click on the "Make your choice" button.

Technical usage questions

Can an instance be up- or downscaled hot?

No. To change the flavour of an instance, you have to restart the server.

Can you add a local SSD volume to an instance?

No. The additional volumes must be external Ceph volumes.
Can you mount an additional volume on several servers at the same time?

No, although this feature is currently being developed on OpenStack. It will be available in future releases.

Can you resize a volume dynamically, while continuing to write on the disk?

No. You must detach a volume before resizing it.

Do volumes have an global IOPS limit, or is there a specific limit for each volume?

Each volume has its own IOPS limit. There is also a global limit for instance models, which varies depending on their size.

How many additional volumes can I attach to each instance?

You can attach up to 26 additional volumes per instance.

How are my servers secured?

The entire OVH infrastructure is protected by our industry-leading anti-DDoS solution. In addition, you can add the OpenStack security groups. This firewall equivalent is managed directly through the OpenStack infrastructure, above your instances.

These protections, combined with others that can be launched on your servers, will help you maximise the reliability of your solutions.

How can I create a private network between my servers?

The OVH Public Cloud includes a software-defined network (SDN) solution. This allows you to dynamically create private networks and connect them to your instances, which can be done via the OVH Control Panel or the API.

These private networks are created with OVH's vRack technology, which is also compatible with our other solutions, such as Private Cloud or dedicated servers. It enables isolated, secure connections between the different elements of your infrastructure and OVH’s datacentres.
