General Purpose

The b2 instances comprise an Intel processor and correspond to our legacy instances. The b3 instances comprise an AMD processor, and is our latest range. You also get better network performance with the b3 range.

A General Purpose instance is a type of cloud computing instance. It is designed to achieve a balance of compute, memory, storage and network resources, making them suitable for varied applications and workloads.

OVHcloud General Purpose instances are versatile and generally suited for a wide range of tasks, from managing web servers to running databases and business applications. While they are not designed for specific use cases, they offer a general computing capacity that can meet the needs of many applications.

OVHcloud offers a wide range of instance types to meet your computing, memory, storage, and performance needs.

• General Purpose instances provide a balance between computing power, memory and storage. They are suitable for a wide range of applications and workloads:
• Compute Optimized instances: designed for compute-intensive workloads, such as data processing, modelling, simulation and rendering.
• Memory Optimized instances: designed for memory-intensive applications, such as in-memory databases and data analysis. They have a high amount of RAM.
• Storage Optimized instances: perfect for workloads requiring fast, high-capacity data storage, such as massive databases or streaming applications.
• Graphics Processing Unit (IPU) instances: equipped with graphics processing units (GPUs) and used for tasks, such as machine learning, 3D visualisation, modelling and simulation.

Yes, you can migrate, under certain conditions. The main requirement is the size of the destination disk, which must be equal to or larger than the size of your current model.
This means that the target b3 instance must have at least the same storage size as the current instance.

To migrate your b2 instance to a b3 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 will be able to restore your backup using the original model if you encounter any problems after the change.

The SLA guarantees 99.999% monthly availability on instances. For further information, please refer to the Terms and Conditions of Service.

Instances are virtualised by the KVM hypervisor in the Linux kernel. KVM is an open-source solution that has proven its reliability for many years. VMs are fully-virtualised, with no guest system changes required. KVM also offers advanced features such as live migration for virtual machines.

Yes, each instance can be backed up by generating an image in the Private Image Catalog. You can also schedule backups to be automated. For optimal snapshot security and consistency, we strongly recommend installing Qemu guest agent.

Yes, our anti-DDoS protection is included with all OVHcloud solutions at no extra cost.

Yes, Public Cloud private networks are an integral part of the vRack network, and interconnects different OVHcloud solutions to one another.

Yes, an IPv6 address is assigned for each instance using a public network interface.

Yes, you can use an instance configuration file. This will be run when your machine launches. This file will be supported by cloud-init, which accepts different formats such as standard scripts or cloud-config syntax.

Yes. In the OpenStack API, you can use the shelve function. It will automatically back up the instance, save the configuration, and free up the resources. When you use the unshelve function, the same process will be carried out in reverse to restore the instance to its original state.

Indirectly, yes. You can use affinity or anti-affinity groups that place the instances on the same hypervisor or on different hypervisors, respectively. For example, an anti-affinity group ensures that no instance works on the same hypervisor as another instance in the group. This rules out the risk of losing several instances in the same group, if a hypervisor stops working.

Choosing the right cloud instance depends on the balance required for your application needs, budget, and performance requirements. We often recommend starting with an iterative approach, monitoring application performance and tuning instances as requirements change. Want to try out our instances?
