1 The Future of Cloud Computing: Elasticity, Legacy Support, Interoperability and Quality of Service Introduction and overview of the workshop Alex Delis and Michael Pantazoglou, University of Athens

2 The SUCRE approach The SUCRE project investigates and suggests means for reinforcing the adoption of open source cloud solutions by key stakeholders facilitates the interaction between academia and industry as well as among industry players sets up an all-embracing still focused supporting mechanism available to all EC funded projects in the areas of Cloud Computing and Open Source 2

3 The SUCRE Umbrella Use cases: Usage of open Clouds in high-impact domains Public sector Healthcare provisioning industry Tools and mechanisms for EU-Japan collaboration EU-Japan Expert Group Dissemination Media: magazine, videos, portal Addressing both specific and broader issues/audiences Workshops, Young Researchers Forum, Networking, Events Community oriented workshops, EU-Japan discussion, Young Researchers and Cloud Computing, Dialogue among and between the cloud and open source communities 3

4 Cloud Computing Landscape in Europe SUCRE Findings Benefits of Cloud Computing Standardization of business processes Reduction of IT management and maintenance overhead Improvement of productiveness Reduction of risks Robustness Optimization of resources Optimization of costs Avoid Data Loss Flexibility Improvement of backup abilities Elasticity Cost flexibility Focus on core business processes Environmental-friendly computing Improve the usability of the IT systems Scalability Reliability Improved execution time Flexibility in disk space usage 4

5 Cloud Computing Landscape in Europe SUCRE Findings Obstacles in adoption of Cloud Computing Legal or privacy restrictions Lack of legislation Lack of an overall strategy Lack of SLAs Loss of governance Ignorance of benefits Lack of knowledge and understanding Cost of migration Service availability Lack of migration capability Lack of specialized staff and insufficient human resources Security Previous investments Financing and funding issues Scalability Broadband connectivity 5

6 Cloud Computing Landscape in Europe and beyond SUCRE Findings EU-Japan Experts Group: Recommendations on Cloud standardization General status and regional approaches Standardization can be pursued through adoption of Open-Source Clouds At the same time, marketing issues should not be neglected Industrial collaboration and diversification Cooperation is key to standardization, although companies choose to remain different in technology aspects on which they are holding a leading position Diversity and overflow of standards can be tackled by selecting highly specific issues at an international level, e.g., between Japan and the EU Challenges and ongoing efforts in all Cloud layers SaaS and PaaS are more challenging due to greater diversification IaaS needs further standardization efforts 6

7 Cloud Computing Landscape in Europe and beyond SUCRE Findings Findings on Data portability and Cloud lock-in Data portability is a more politically than technically pressing issue Specialization vs. Portability: Two contradictory values Standardization and security aspects are important to be addressed Cloud providers will be convinced to fully support data portability by Client demand (which leads to increased revenues) Regulatory frameworks (e.g., the EU Data Protection Directive) 7

8 Responding to the SUCRE findings Purpose of the Workshop Pre-FIA workshop: focuses on solutions related to cloud elasticity, migration and interoperability addresses issues related to the level of adoption of Cloud Computing in Europe as well as technological challenges hosts presentations delivered by keynote speakers and EU-funded projects Aim is to: Inform participants on cutting-edge developments in the area of cloud computing facilitate exchange between speakers and participants 8

9 Main Topics of the Workshop Cloud Computing from the Business Perspective Legal and economic aspects, SLA Innovation and differentiation in the Cloud market place Interconnection of public and private clouds vendors Cloud migration issues Overcoming Technical Challenges in Cloud Computing Quality measures, monitoring mechanisms, prediction models, and adaptive policies Portability and interoperability issues Elastic resource scaling in an automated and real-time manner 9
