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

CONTRAIL partners•France:
•INRIA – Lead•Edge-IT
•Germany•ZIB
•Italy•CNR•HP Italy•Tiscali
•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

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
contrail-project.eu7
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”

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

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
contrail-project.eu10
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++
contrail-project.eu11
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
contrail-project.eu12
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

CONTRAIL – Use Cases1. Distributed Provision of Geo-Referenced Data
o Tourist data on digital globe
2. Multimedia Processing Service Marketplaceo Content provider, licences
3. Clouds for High Performance Real-Time Data Analysiso Analysis of beamline data, fitting models
4. Large Scale Code Analysiso doc4.mandriva.org
5. High Throughput Electronic Drug Discoveryo Pharma use cases, genomics, NGS
