Open Source Contrail Software 7  Open source cloud software Three Contrail releases so far (1.0, 1.1, 1.2) and two on the way Licenses: BSD and Apache 2.0 Packages: Sources on OW2: Releases of single Contrail components ConPaaS elastic cloud services: Virtual Execution Platform: XtreemFS distributed cloud storage:  Compliance with cloud standards OVF (for application description), CIMI (for IaaS providers) OCCI (planned,for IaaS providers), WS-Agreement (by reusing  Cloud platforms supported now:next: contrail-project.eu

8 © Copyright 2012 Hewlett-Packard Development Company, L.P. Main Contrail SLA research outcomes /1 SLA Quality Model – classification of terms unobservable/observable/enforceable static/dynamic (wrt time) – definition of Contrail SLA terms – implementation of basic terms (e.g. geographical location) – definition of advanced QoP terms (e.g. minimum_LoA) Monitoring – architecture and implementation of monitoring for a federation of clouds (based on AMQP messaging domains and xdomain gateways) 8 unobservable observable enforceable contrail-project.eu

9 © Copyright 2012 Hewlett-Packard Development Company, L.P. Main Contrail SLA research outcomes /2 SLA Specification – based on syntax – extended to reference and use a standard OVF descriptor to specify the IaaS service express guarantees about items specified in OVF (e.g. VirtualSystems) fit the pricing model defined for generating automatic quotations SLA Negotiation – Implementation of automated SLA offer generation for a Cloud provider – Defined pricing data model to support providers' automatic quotations – Implementation of federation negotiation with multiple providers – Implementation of selection of best SLA offer according to user criteria 9 contrail-project.eu

10 © Copyright 2012 Hewlett-Packard Development Company, L.P. Main Contrail SLA research outcomes /3 SLA Lifecycle – based on framework with some differences, such as service provisioning based on OVF and separated from SLA agreement definition of two different SLA types: generic and specific – use of SLAs for Cloud federations Cloud brokering (with automatic Provider selection) Cloud aggregation (application distribution over multiple providers) – research on SLA splitting Introduced it as a new concept Classification and analysis of three types of splitting strategies 10 contrail-project.eu

11 © Copyright 2012 Hewlett-Packard Development Company, L.P. Added value of Contrail approach: Federation as a Virtualization of Clouds Contrail Federations relieve the user from managing cloud providers Worldwide Clouds made possible Comparing SLAs and selecting the best provider opens new Cloud mediators market Automatic SLA negotiation allows Cloud providers to personalize their offer Enhanced Dependability with respect to Clouds today – Common, pervasive security infrastructure X.509 certificates, SSL for communication, UCON policies, … – Specific Quality of Protection SLA terms location, reliability, delegationSecurity, minimum_LoA, … 11 contrail-project.eu

12 © Copyright 2012 Hewlett-Packard Development Company, L.P. SLAs in Contrail are the main pillars for Cloud Federations Federation: abstraction of providers – SLA+OVF is a unified way for expressing user requirements QoS/QoP requested by each customers can be satisfied irrespective of the provider Federation: broker of providers – Provider selection is based on SLAs new market and business model for intermediate players Federation: small providers can join forces – SLA splitting allows distributing application over multiple providers cross-provider enforcement strategies also made possible SLA Federation Cloud B C C A A B B Federation C C A A B B 12 contrail-project.eu

13 © Copyright 2012 Hewlett-Packard Development Company, L.P. Follow-up activities / uptake of results The SLA component in association with the Federation raised some attention internally in HP and we are currently following up to propose the solution to potentially interested customers A public event is being planned in HP Italy for September 2013 to propose Cloud solutions to customers, with Contrail as central subject of the event Contacts are also underway with people from other EU projects (p- medicine) interested in the topic of SLA and OpenStack Some FP7 Call 8 projects (e.g. CloudScale and PaaSage) indicated the reuse of Contrail software as a concrete possibility Several projects proposals involving reuse and /or building upon Contrail have been presented in recent EU calls All Contrail partners have a serious plan for the exploitation of project results 13 contrail-project.eu

14 © Copyright 2012 Hewlett-Packard Development Company, L.P. Potential recommendations Targeting and sustaining the federation of small Cloud providers is a way for raising at a worldwide level the competitiveness of European Cloud market Cloud providers should enrich their offer of SLA Terms beyond availability, especially targeting QoP terms such as location and others QoP research can still progress further and must be sustained 14 contrail-project.eu
