Concepts

The VM Instances service from Cloud Temple is a SecNumCloud qualified shared compute product, allowing the deployment of on-demand virtual machines without managing the underlying infrastructure. This page presents the fundamental concepts of the service.

Regions and Availability Zones​

The VM Instances service is deployed in the FR1 region. When creating a virtual machine, you can choose the Availability Zone (AZ) in which it will be hosted.

To learn more about availability zones and Cloud Temple regions, see:

Service Classes​

The service offers three service classes tailored to different types of workloads:

ClassDescriptionResources
DevelopmentCost-optimized, for test, integration, and staging environments. Suitable for non-critical workloads with variable usage.Shared
General PurposeOptimal vCPU/RAM balance for standard workloads (web applications, micro-services, medium-sized databases).Shared
PerformanceDesigned for intensive workloads requiring high CPU performance. vCPUs are dedicated to ensure consistent performance.Dedicated vCPUs

Flavors​

Predefined flavors are offered for each service class. It is also possible to create custom flavors by freely choosing the number of vCPUs and the amount of RAM.

Development​

Optimized for test, integration, and staging environments with controlled costs.

Custom Flavors​

It is possible to create a custom flavor by freely selecting:

  • The number of vCPUs
  • The amount of RAM

This flexibility allows precise sizing to match application needs while optimizing costs.

note

Flavor specifications may change. Consult the Cloud Temple console for the updated list.

Storage​

All volumes in the VM Instances service are persistent Flash volumes mounted over the network (network-attached). There is no ephemeral local storage: your data is retained independently of the virtual machine's state.

System Disk​

Each virtual machine automatically has a Flash system disk to host the operating system. This disk is a storage resource of the service and is not free; its size depends on the chosen operating system:

  • Size: between 15 and 100 GB depending on the selected OS.

The system disk is billed per GB according to the Cloud Temple official pricing catalog. Its automatic creation with the VM means it is necessary for OS deployment, not that it is included for free.

Additional Volumes​

Additional storage volumes can be added to each virtual machine:

  • Size: from 1 to 2,048 GB per volume
  • Maximum number: 16 volumes per VM
  • Limit per family: 2 TB per VM in Development and General Purpose; 16 TB per VM in Enterprise
  • Granularity: allocation per GB
  • Billing: per allocated GB, with choice of storage class

Storage Classes​

Two block storage classes are available for additional volumes:

ClassUsagePerformanceMinimum sizeMaximum size
EnterpriseHigh-performance block storage for latency-sensitive workloads.7,500 IOPS/TB1 GB2,048 GB
StandardStandard block storage suitable for most workloads.1,500 IOPS/TB1 GB2,048 GB

Network​

Network Interface​

Each VM instance can have 1 to 7 network cards. Each network card is associated with a single network.

Network Compatibility​

This interface can be connected to two types of Cloud Temple networks:

  • Backbone private network: a shared private network with strict logical isolation between tenants. Ideal for interconnecting your Cloud Temple resources in a controlled environment. Learn more
  • VPC (Virtual Private Cloud): a fully managed private network allowing advanced segmentation and fine network configuration of your environments. Learn more

Floating IP​

On a VPC network, it is possible to associate a floating IP with a VM instance. A floating IP is a public IP address that you can attach or detach freely from an instance, independent of its lifecycle.

Virtual Appliances​

Stormshield and FortiVM virtual appliances are compatible with the Enterprise family, subject to meeting technical prerequisites and the applicable support scope.

Deployment and Images​

VM Instances are deployed from the official images of the Cloud Temple Marketplace. The available templates are those from the Marketplace filtered for OpenIaaS. This curated catalog of images guarantees tested, maintained, and ready-to-use environments for each supported operating system.

The service supports Cloud-init for automatic pre-configuration of instances at boot (SSH key injection, network configuration, initialization scripts, etc.).

Migrating an OS outside the Marketplace​

An operating system not available in the Marketplace can be migrated via Veeam restoration in Bare Metal Recovery mode, subject to technical validation. Cloud Temple then guarantees the functioning of the VM infrastructure, but does not guarantee the proper functioning of the guest OS, its applications, or necessary agents when they are not installed or configured correctly. Support for the guest OS is then limited.

A second method is planned with the import of VHD/VMDK disks, to create a VM from an existing image. This feature is under development and targeted for the fourth quarter of 2026; it is not available in the current service.

Data Protection​

Backup (optional)​

Two backup policies are available: No Backup and Backup 30 snapshots. With Backup 30 snapshots, a snapshot is created automatically every night between 8 PM and 10 PM. If the customer triggers an additional backup during the day, two snapshots are created on the same day: the active retention then covers 29 days instead of 30. This option is billed additionally.

info

VM replication is not included by default. Its study is planned for the second half of 2026.
