[sage-hamburg] Reminder übermorgen: Vortrag "dCache, Sync-and-Share for Big Data at DESY" am 2.7.2015, 19h

[Dirk Wetter]

Moin,

hier der Reminder für Donnerstag -- übermorgen -- abend.

Damit bei dem Sommereinbruch die Leute nicht vor Durst weglaufen
gibt's ausnahmsweise noch ein Kasten Bier und etwas Limo *währenddessen*.

Das Bier/Eis/wasauchimmer danach dann draußen im Grindelviertel bei
den üblichen verdächtigen Etablissements.

Schönen Gruß, Dirk

> ---------
> The availability of cheap, easy-to-use sync-and-share cloud services has split the scientific
> storage world into the traditional big data management systems and the very attractive cloud
> services. With the former, the location of data is well understood while the latter is mostly
> operated somewhere in the Cloud, resulting in a rather complex legal situation.
> 
> Beside legal issues, those two worlds have little overlap in user authentication and access
> protocols. While traditional storage technologies, popular in High Energy Physics (HEP), are
> based on X509, cloud services and sync-n-share software technologies are generally based on
> user/password authentication or mechanisms like SAML or OpenID. Similarly, data access models
> offered by both are somewhat different.
> 
> As both approaches are very attractive, dCache.org developed a hybrid system, providing the
> best of both worlds. To avoid reinventing the wheel, dCache.org decided to embed another Open
> Source project: OwnCloud. This offers the required modern access capabilities but does not
> support the managed data functionality needed for large capacity data storage.
> 
> With this hybrid system, scientist can share files and synchronize their data with laptops or
> mobile devices as easy as with any other cloud storage service. On top of this, the same data
> can be accessed via established mechanisms, like GridFTP to serve the Globus Transfer Service
> or the WLCG FTS3 tool, or the data can be made available to worker nodes or HPC applications
> via a mounted file system. As dCache provides a flexible authentication module, the same user
> can access its storage via different authentication mechanisms; e.g., X.509 and SAML.
> Additionally, users can specify the desired quality of service or trigger media transitions as
> necessary, so tuning data access latency to the planned access profile. Such features are a
> natural consequence of using dCache.
> 
> We will describe the design of the hybrid dCache/OwnCloud system, report on several months of
> operations experience running it at DESY, and elucidate on the future road-map.
