  1. CONTRAIL SecurityOpen Computing Infrastructures for Elastic Services Call FP7-ICT-2009-5 Proposal Number FP7-257438 Dr Jens Jensen jens.jensen.at.stfc.ac.uk STFC e-Science Centre, Oct 2010

  2. CONTRAIL project - background • EU funded • “Internet of Services” programme • Three year project • Started 01 Oct 2010 • Goals: • Open Source PaaS and IaaS • Workflow, MapReduce, • Federation: flexible provider/consumer boundaries

  3. Netherlands Genias VUA Slovenia XLAB UK Constellation Tech STFC CONTRAIL partners • France: • INRIA – Lead • Edge-IT • Germany • ZIB • Italy • CNR • HP Italy • Tiscali

  4. Main Innovations and Contributions • Enhanced platform scalability, performance and security • Complete software stack for IaaS • Scalable fault-tolerant storage for Clouds • Self-optimizing, self-healing properties • Secure private network • QoS integrated within infrastructure (storage, network, VMs) • Efficiency through vertical integration of PaaS and IaaS • e.g. Map/Reduce on GAFS file system • Seamless integration of (external) user resources • European, Open approach to Cloud Federation • Federations as an evolving market for IaaS • Contribute to the standardization process 4

  6. Contrail Output: IaaS • Cloud Buzzword: PaaS, IaaS, (DaaS) • Network: VIN – Virtual Infrastructure Networks • Virtualisation: • Hardware (Xen, KVM,…) • Process (OpenVZ, chroot) – sort of like pilot jobs • Booting images • Storage: • Global Autonomous File System (GAFS) • Built on XtreemFS • “Open Source cloud storage not cloudy” – lack elasticity

  7. Contrail Output: PaaS • Structured data services • Eg databases • Distributed Key/Value store • Runtime environments • MapReduce • Dynamic allocation of resources • “Independent services scale differently” • “Tightly coupled stack” • “Increase performance and integration”

  8. CONTRAIL Security • Security Work package • Lead: STFC • Main collaborators: INRIA, XLAB, CNR • Minor collaborators: Tiscali, HP, EDGE-IT • Use of formal methods • verify architecture and implementation • Cf. B, Z, Event-B • Learning from other EU-funded projects such as DEPLOY • Accounting • SLAs • QoS – Quality of Service • QoP – Quality of Protection

  9. CONTRAIL – Security Loose Ends • Role of security in federation • Managing policies and resource sharing • Authentication • Planned to use XtreemOS (X.509 sans GSI) • Also compare RESERVOIR (also X.509 but non-IGTF currently) • QoS is also security • Eg availability • QoP is security • Eg integrity • Securing (virtual) networks • Securing VM images

  10. CONTRAIL – Security Loose Ends • Does “traditional” security apply to clouds • Understand and mitigate risks • Users and trust • Cf CSA threats • Moving data outside trusted boundary • Legal issues with moving data • Security of VM images • Cf. current work from HEPiX, JSPG, JSPG++

  11. Service Provider – DDoS • RESERVOIR: “DDoS is greatest risk” • Methods for dealing with attack • Compare scaling existing services • “Cloud bursting” • Risk of billing user • However, most “attacks” we see are “unintentional” • Neither malicious, nor needing scaling • Dodgy scientist code • Users who don’t understand pitfalls of dist’d comp

  12. CONTRAIL - Standards • Recognise OCCI as the “most promising” • Did not consider CDMI (not available when proposal was written) • Commitment to standardisation • Not clear what, yet • Need to aim up-front, though • Need to liaise/collaborate with EGI and EMI? • SLAs from SLA@SOI and others • Not standardised • “Can standardise underlying model” • “Concertation”proposed standards bodies • ETSI, W3C, OASIS, OGF, OMG

  13. CONTRAIL – Use Cases • Distributed Provision of Geo-Referenced Data • Tourist data on digital globe • Multimedia Processing Service Marketplace • Content provider, licences • Clouds for High Performance Real-Time Data Analysis • Analysis of beamline data, fitting models • Large Scale Code Analysis • doc4.mandriva.org • High Throughput Electronic Drug Discovery • Pharma use cases, genomics, NGS
