OVHcloud vRack

• Data Processing can not use or access OVHcloud vRack.

Available regions

Storage

• Before submitting a job, you will need to upload your job into your OVHcloud Object Storage account.
• To process data, your data can be stored in OVHcloud Object Storage or any other cloud storage or connected storage that is accessible through public internet.

Resources quotas

We distinguish three types of resources: CPU cores, RAM and Instances.

You have a limited amount of those resources that you can use simultaneously. If you have a job using all of your quotas, you will not be able to submit other jobs until it is completed. The maximum amount of each resource you can use simultaneously is fetched from your cloud project quotas. Only the maximum quotas are shared between Data Processing and your cloud project. If you run out of resource on your cloud project, it will not impact your ability to submit a job on Data Processing.

If you would like to increase the quotas for Data Processing you will need to increase your cloud project quotas. Please visit Increasing Public Cloud quota for more details on the subject.

Planned features

• Ability to set a TTL (Time To Live) on your jobs
• Availability in different OVHcloud regions
