  2. WP4 Objectives • Assemble the resources needed to meet the requirements provided by WP3, plus the tools necessary to configure, deploy, monitor and evaluate the flagship. Specific goals • To produce, validate and make available a method of determining and describing a suitable service offering to meet user requirements for the Science Cloud (beyond tools). • To produce, validate and make available a method of matching services to requirements in any specific case. • To deploy that method in the three flagships, based on the specific requirement statements for each flagship (from WP3), in order to allow evaluation (by WP9) of the approach. - 2 -

  3. The high level process This high level method is part of the process description to match services to requirements resulting from Work Package 4 The matching process - 3 -

  4. Effort Contribution • Lead Beneficiary: Atos WP4 – 1pm WP4 – 21 pm Extension of WP4 into P2 requested to update D4.3: ‘Cloud Provisioning Report’ with the evaluation of the pilots afterthey are completed. - 4 -

  5. Scientific/technical achievements and their impact • The main objective of Work Package 4 (service provisioning) is to produce, describe and analyse a suitable service offering. WP4 is at the centre of the project execution since it liaises: • Work Package 3 where requirements for the flagships use cases are elicited and • Work Package 5 where the response to those requirements is instantiated for each of these use-case. • The main contribution of Work Package 4 to Helix Nebula has been in bringing knowledge and experience of how “services” are actually delivered. This has included, for instance, documentation of the options and recommendations regarding the establishment of a “broker” role. • Work Package 4 has documented many of the service aspects, which have also appeared in the documents produced by the Service Architecture (ServArch) team. - 5 -

  6. Requirements perspectives Example of knowledge and experience of how “services” are actually delivered contributed by Work Package 4 to Helix Nebula Requirements situation at the start of the project [1] Open Data Center Alliance, see: http://www.opendatacenteralliance.org/ - 6 -

  7. Deliverables and Milestones – Period 1 - 7 -

  8. Overall modifications, corrective actions, re-tuning of objectives • Initially WP4 followed the Waterfall approach as described in the Seventh Framework Programme • During the execution it became clear that a more iterative and innovative approach resulted in a more efficient and effective way in product delivery • Learning in relative short cycles is an efficient way to deliver products with a higher quality • Following an iterative approach means: • extra effort is needed to schedule additional product and review cycles • extra effort is needed for monitoring the development in requirements (Requirements management) • release management must be in place in order to have control on the progress and development of versions of the deliverables. - 8 -

  9. Exploitation and use of foreground • Knowledge and experience of how Blue Box services are actually delivered, and documentation of options and recommendations regarding the establishment of a “broker” role, were the main contributions of Work Package 4 to Helix Nebula   • Documentation of service aspects (see also documents produced by the Service Architecture (ServArch) team) • Contributed to the identification and description of the roles in the HN ‘value chain’, elaborated in Work Package 7 (business models) • Above mentioned aspects are crucial for the establishment of Helix Nebula as a viable and sustainable service, incorporating both commercial and public contributions - 9 -

  10. Cooperation models Contribution by Work Package 4 to the identification and description of the roles in the HN ‘value chain’, elaborated in Work Package 7 (business models) - 10 -

  11. Implementation without Blue Boxduring Proof of Concept Without a Blue Box each customer and supplier have a point-to-point connection resulting in M x N relationships - 11 -

  12. Helix Nebula Proofs of ConceptLearnings from the Supplier perspective • The technology works: required workloads from participating scientific organisations can be successfully deployed in cloud environments • The Demand sides each had slightly different requirements, and Supply-side clouds all differ significantly in implementation, even those sharing common hypervisors • so each user-supplier case was effectively a bespoke deployment • Software requirements (“legacy”) from the demand side can be complex and are critical to understanding POC requirements and ensuring a successful outcome • A common API is desired and would significantly streamline driving deployments across multiple clouds • The ability to move VM images between clouds and potentially convert VM formats is needed for better cross cloud deployment • Differences between private and public deployment models on the supply side are important and influence various aspects of PoC’s directly • i.e. WAN, open Internet or VPN access • Networking between demand-side institutions and supply-side providers, and between multiple supply-side providers, is an important success criteria • Areas such as service structure/architecture require further exploration

  13. Proof of Concepts were successful • All PoC environments completed successfully by most suppliers • Clouds can deliver the facilities required to fulfil the scientific requirements • starting at the IaaS level • Inter-Supplier communication (open and often) was crucial to success • We now/then need(ed) to move on to improving the overall experience • making the multi-supplier environment more coherent • performance optimisation and price/performance not yet considered • Points of learning for further addressing • common interfaces: e.g. unified API • server image management and conversion, especially to cope with bespoke/ legacy software usage • inter-cloud workload assignment and scaling • networking: bandwidth and interfaces, charging algorithms • breaking the demand-supply scaling “chicken and egg” syndrome • common charging and billing mechanisms not yet in sight

  14. Blue Box functions Each customer and supplier have a single connection to the Blue Box resulting in M + N relationships - 14 -

  15. Blue Box use in pilot Implementing two Blue Boxes in the pilot improves the evaluation by adding practical experience to the study before the pilot - 15 -

  16. Interaction with other FP7 projectsand stakeholders outside the consortium • Taking part in the Select Industry Group (SIG) discussions, established by the EC as part of the European Cloud Partnership (ECP) programme. • Active member of the Open Data Centre Alliance (ODCA http://www.opendatacenteralliance.org/) which is developing common user requirements, leading to implementation within standards, for many of these subjects. • Use has been made of knowledge gained from the development of other cloud management projects, such as Optimis (www.optimis-project.eu), BonFire (www.bonfire-project.eu) and Stratuslab (stratuslab.eu) for interaction with FP7 projects. - 16 -

  17. Contribution to the disseminationof project results • Most of the documents produced by Work Package 4 (and the associated documents produced by the ServArchteam) have been published on the Helix Nebula web site. • Service aspects have been discussed at a number of internal Helix Nebula events and externally, most recently at IM2013 (http://www.bdim.net/2013/). WP4 has also contributed to position the HN initiative in several conferences such as EUDAT with data infrastructure providers. These have helped promulgate the services, as opposed to just technology, thinking that is necessary for such developments to succeed. • Work Package 4 has also contributed to the Communications Plan and reviewed other deliverables - 17 -

  18. Summary • WP4 very useful for obtaining a clear statement of the Requirements, beyond the technical configurations required • Acted as a linking point between gathering requirements (WP3) and flagship deployment (WP5) • Highlighted the need for service aspects, rather than technical, aspects, especially as regards federation and brokerage • Necessary to act as ambassadors for the need to define a complete Service Architecture, most of which was done outside the scope of this WP • Also highlighted the business questions and need for business requirements that arose from WP7 - 18 -
