CONTRAIL Security Open Computing Infrastructures for Elastic Services Call FP7-ICT Proposal Number FP Dr Jens Jensen jens.jensen.at.stfc.ac.uk STFC e-Science Centre, Oct 2010

contrail-project.eu 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 2

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

contrail-project.eu 4  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 Main Innovations and Contributions

contrail-project.eu 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 6

contrail-project.eu 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” 7

contrail-project.eu 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 8

contrail-project.eu 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 9

contrail-project.eu 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++ 10

contrail-project.eu 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 11

contrail-project.eu 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 and others Not standardised “Can standardise underlying model” “Concertation”proposed standards bodies ETSI, W3C, OASIS, OGF, OMG 12

contrail-project.eu CONTRAIL – Use Cases 1.Distributed Provision of Geo-Referenced Data o Tourist data on digital globe 2.Multimedia Processing Service Marketplace o Content provider, licences 3.Clouds for High Performance Real-Time Data Analysis o Analysis of beamline data, fitting models 4.Large Scale Code Analysis o doc4.mandriva.org 5.High Throughput Electronic Drug Discovery o Pharma use cases, genomics, NGS 13
