Getting Access to CESNET S3

Obtaining a User Account

The procedure to get access to the service depends on your needs.

Access to an Existing Virtual Organisation

You may have been invited to an existing Virtual Organisation (VO) by the VO manager. In that case, follow instructions given to you by the VO manager to register.

Personal S3 Access

Provided you are seeking an S3 service that

provides just a personal S3 space for your own use,
doesn’t support sharing between users and/or groups,
has a standard quota of 2 TB (can be increased on request),
but is available just upon simple registration (you need to be an employee or a student of a Czech public university, the AS CR, or an employee of a CESNET customer; you are expected to declare your eligibility using the identity federation), you are invited to register at https://einfra.cesnet.cz/allfed/registrar/?vo=VO_s3&group=s3_cl4.

Group S3 Access, aka “Virtual Organisation”

In case you need access to S3 and the conditions of Personal S3 Access above don’t fit your needs, we will typically prepare a “Virtual Organisation” and appropriate S3 service for you individually.

Contact our support at support@cesnet.cz and we’ll discuss your expectations with you.

You can also refer to common S3 use cases for inspiration about serving typical use cases.

Accessing the Storage

When you finished your registration (or your brand new VO has been set up for you), you will be notified by mail. Then you need to get credentials to access the storage itself.

User Account Management

You will need a suitable S3 client, and to configure it with your storage access credentials.

Obtaining access credentials to the storage
Access credentials to most of our object storage facilities are available through https://access.du.cesnet.cz.

Kindly note that personal S3 appears as “Personal Account” in the system; other Virtual Organisations are listed individually. We recommend using separate access/secret key pair for each and every specific tool you access the storage with.

It is useful to distinguish following systems:

Perun (https://einfra.cesnet.cz/) is a system managing which users have access to particular services (based on your membership in Virtual Organisations and groups)
Gatekeeper (https://access.du.cesnet.cz] will give you credentials to the storage based on what Perun says
and finally, the storage itself is accessed with those credentials by a client you prefer.
