2. The Rucio Data Lake: Standalone Rucio instance running on CERN premises
3. REANA: Standalone REANA instance running on CERN premises
4. CVMFS: mounted on the VRE + ESCAPE-specific repo to host the collaboration’s SFT stack
5. JupyterHub: Central aggregator for services and functionalities

User’s interactions with the VRE

What makes the VRE, the VRE

Towards the VREx

The next generation of VREs

​

Two-fold scope

​

• CERN / ESCAPE
1. Consolidate the VRE concept and functionalities within ESCAPE (ET, ESO, CTAO, etc)
• e.g. common Helm charts
2. Help bridging existing services at CERN and build a modular / plug-n-play solution
3. Expose an easy to access, fully integrated analysis environment for SME-like communities

​

• EOSC
• Streamline EOSC AAI integration within the VRE (ongoing summer project with REANA)
• Deploy part of the VRE functionality (REANA and Rucio exts.) on the existing EOSC EU Node
• Enrich the current VRE configuration to accommodate for more CERN services

ScienceBox

Initial inputs

​

From Kuba’s suggestions on the VREx proposal

​

• Leverage successful ScienceBox deployments on commercial clouds to establish a baseline for connecting the VRE to off-premise resources.
• Streamline charts between ScienceBox components (SWAN, EOS and CERNBox) and the base layer VRE charts
• Optional add-on(s) for sites that want to deploy CERN storage technologies in addition to other CERN developed products.
• Leverage federation capability of the Sync&Share storage deployed at the EOSC EU node.
• Further synergies to be explored with the EOSC Data Commons project (IT-SD)
