Unlock the potential of your applications with high performance computing, and reduce costs with our cost-effective and transparent pricing.
High performance computing
Get cloud servers adapted for applications that require high performance computing, with 1 vCPU per 2 GB RAM ratio.
100% of your resources, 100% of the time.
Harness the full power of your server. These instances have guaranteed resources continuously allocated 100%, to meet the slightest requirements in terms of power.
The flexibility of the Cloud
Find the instance that best suits your needs: a hyper-competitive startup with a small instance like c3-4, up to much more powerful instances like c3-128.
ISO/IEC 27001, 27701 and health data hosting compliance
Our cloud infrastructures and services are ISO/IEC 27001, 27017, 27018 and 27701 certified. These certifications ensure the presence of an information security management system (ISMS) for managing risks, vulnerabilities and implementing business continuity, as well as a privacy information management system (PIMS). Thanks to our health data hosting compliance, you can also host healthcare data securely.
Use cases
Specialist tasks
Many applications designed to perform specific tasks (machine learning, for example) have very-specialist computing requirements. However, once the task in question is complete, there is no need to maintain an inactive server. CPU instances are perfect for these kinds of one-off tasks.
Data intensive computing
These CPU instances are generally used for back-end applications (databases, queue servers) and batch jobs. They provide flexibility and processing capacity to handle high traffic surges and deliver smooth user experience, and ensure better performance.

Your questions answered
What is a Compute Optimized instance?
A Compute Optimized instance is a type of cloud computing instance. It is designed to handle compute-intensive tasks and workloads such as data processing, modelling and simulation.
What are the differences between the c2 and c3 ranges?
The c2 instances correspond to our legacy instances. They comprise an Intel processor, while our c3 instances are part of our latest range and comprise an AMD processor. Our latest c3 range offers improved network performance.
What is the difference between a Compute Optimized Instance and a General Purpose Instance?
The difference between using a Compute Optimized Instance and a General Purpose Instance lies in their technical specifications. Compute Optimized instances are equipped with processors and resources optimised for compute-intensive tasks. They are therefore more likely to be used for applications requiring high raw computing power than memory and storage capacity. Our General Purpose instances, on the other hand, deliver a balance between computing power, memory and storage, which provides optimal versatility
Can I migrate my current c2 instance to a new c3 instance?
Yes, you can migrate your c2 instance to one from our latest range. The only requirement is the size of the destination model’s disk, which must be equal to or larger than the size of the source model. In addition, your target instance must have at least the same storage capacity as your current instance.
How do I migrate my c2 instance to a c3 instance?
To migrate your c2 instance to a c3 instance, you will need to edit your instance and change your model.
Changing your model may result in server downtime for a few minutes. Server downtime duration may vary depending on the model. In some cases, this may take more than an hour. It is recommended that you back up your instance before changing it. You can restore your backup using the original model if you encounter any problems after the change.
Which SLA is guaranteed by OVHcloud for this instance?
The SLA guarantees 99.999% monthly availability on instances. For further information, please refer to the Terms and Conditions of Service.
Do Compute Optimized instances have anti-DDoS protection?
Yes, all OVHcloud solutions have Anti-DDoS protection.
Can I integrate a Compute Optimized instance into the OVHcloud virtual private network (vRack)?
Yes, you can integrate an instance into the vRack network.
Can an IPv6 address be used on these instances?
Yes, each Instance comes with an IPv4 address and an IPv6 address.
