Objective

This document is the reversibility policy for the Public Cloud Compute, Object Storage and Block Storage activities.

This policy aims at implementing the global reversibility principles and requirements of SWIPO IaaS Code of Conduct for Cloud Providers.

Features map

Public cloud features are divided into three categories:

  • The core features for which we guarantee the ability to migrate
  • The OVHcloud implementation, whose migration will require adaptations to a new environment.
  • Specific functionalities, whose migration as such is impossible to guarantee as they are tied to OVHcloud environment or specific developments.

Architecture listing

All components of Public Cloud products are accessible through the OVHcloud Control Panel. This allows to visualize and manage the instances, volumes, object containers ... as well as the features that are attached to these components.

Horizon webUI also allows to view architecture components.

Partner services

OVHcloud Partners are listed with the "Cloud Migration" keyword in the dedicated directory.

Cost and fees

No additional billing is planned from OVHcloud for the migration features listed here.

Retention of data after contract termination

On object storage, the data is retained 7 days after the termination of the service and then deleted permanently.
