Objective
This guide explains the technical capabilities and limitations of Public VCF aaS (aka Public VCF as-a-Service), including resource constraints and configuration restrictions.
Requirements
Before getting started, review the following guides to better understand Public VCF as-a-Service:
- Public VCF as-a-Service - Fundamental Concepts
- Public VCF as-a-Service - Network Concepts
- Creating a VM on Public VCF as-a-Service
- Creating network components via Public VCF as-a-Service
Instructions
General limitations
| Resource | Standard | Advanced | Premium | Comments |
|---|---|---|---|---|
| vCPU (per VM) | 32 | 32 | 32 | Number of available vCPUs per VM. |
| RAM (per VM) | 128 GB | 128 GB | 128 GB | Maximum RAM per VM (min. 0.5 GB). |
| Network Cards (per VM) | 10 | 10 | 10 | Maximum number of network adapters per VM. |
| Edge Gateway (per organization) | N/A | 5 | 5 | Maximum number of Edge Gateways per organization. |
| Public IPs (per vDC) | N/A | 2 | 2 | Number of available public IPs per vDC. |
| Snapshots (per VM) | 1 | 1 | 1 | Maximum of 1 snapshots per VM. |
| VMs (per vApp) | 128 | 128 | 128 | Maximum number of VMs allowed per vApp. |
| VMs (per organization) | 2000 | 4000 | 4000 | Maximum number of VMs per organization. |
| vApps (per organization) | 10,000 | 10,000 | 10,000 | Maximum number of vApps per organization. |
| Segments (per organization) | 40 | 40 | 40 | Maximum number of segments per organization. |
Note: When creating a snapshot that includes the VM's memory, storage usage can quickly add up. For example, if you have 1 VM with 1 GB of RAM and a 10 GB disk, and you create a snapshot that includes memory, your storage usage will be: 10 GB (disk) + 1 GB (VM swap) + up to 10 GB (disk snapshot) + 1 GB (memory snapshot) = 22 GB total.
Hardware limitations
| Resource | Standard | Advanced | Premium | Comments |
|---|---|---|---|---|
| vCPU Frequency Min | 1 GHz | 1 GHz | 1 GHz | In Roadmap. |
| vCPU Frequency Max | 3 GHz | 3 GHz | 3 GHz | By Default. |
| Storage per VM (VMDK) | 1.5 TB | 1.5 TB | 1.5 TB | Storage limit on VMDK. |
Limitations of integration with external applications
Backup Solution
With Public VCF as-a-Service, you cannot use a backup tool other than our managed Veeam for VCD tool. Refer to the following guide for more information: Public VCF as-a-Service - Backups with Veeam Data Platform.
VMware API
Third-party products relying on vSphere APIs to function (such as Naviko, Rubrik or Zerto (non-exhaustive list)) are currently not usable within the Public VCF as-a-Service product.
Certifications
At the launch of the service, no specific certification will be applicable to the Public VCF as-a-Service by OVHcloud. However, supporting HDS, ISO27001, SOC2, or PCI-DSS certifications is one of the objectives of our roadmap.
