  1. Research Trends and Challenges in Cloud Computing Lars Lundberg School of Computing Blekinge Institute of Technology

  2. Security in Cloud Computing • Securityissues • Performance • Master ThesisBased on SLR and Interviews

  3. Security Challenges • Privacy– Personal information might be handled by companies all over the world. • Espionage – National secret information might be handled by companies in other countries. • Business intelligence – Business confidential information might be handled by companies all over the world • Data ownership – When data is transferred to the Cloud it is important for many organizations to be assured of the continued control of the data. • Examples of reportedchallenges

  4. Performance Challenges • One future performance challenge is live migration of virtualmachinesbetweenphysical servers • Weneed to find a technical solution that reduces the cost and overhead for live migration • Wealsoneed to defineautomaticpolicies and strategiesregardingwhen to do live migration, from where and to where (i.e. from whichphysical server and to whichphysical server) • Balancebetweendistributing the load and minimizing the overhead cost for doing live migration. • Live Migration

  5. Performance Challenges and Trends • An importantchallenge is to be able to guaranteeresponsetimes and otherreal-timequalitiesalso for cloudbased services. • Will we for instance be able to run parts of ourtelecommunication systems in a cloud? • What kind of availability and minimum down time willwe be able to guarantee? • Real-TimeIssues

  6. Architectural Challenges and Trends • FutureArchitectureswilloftenhave a mix of: • Public Clouds • Private Clouds • Traditionallocalcomputing hardware • Therewill be a number of challenges: • The system architectureshould be cost-effective • The system architectureshould provide the capacity and availability that weneed • Who is responsibleif the system fails or does not meet the requirements • Mixed System Architectures

  7. Challenges and Possibilities for (Small) Software Developers • If you deliver your software as a service in the Cloud there are a number of adavantges, e.g., it is easy to reach new customers and scale up. • However, there are also a number of challeges. Since you are delivering a service you are not onlyresponsible for the correctness and function of your software; you are alsoresponsible for the availability (DOS-attacks) and performance of the entire solution. • Can wewriteSLAs that cover thesecases? Whatwillhappenif a customerlosesmoneybecause a DOS attack in a public has made a software service inaccessible or if a storagefailure has resultet in an erroneousresult for the enduser? • Software-as-a-Service

  8. Green IT with the Cloud • Howcanwepush the resourceutilizationevenhigher – morecentralized solutions becomemorevulnerable • Place the physicalcomputerswherethere is no or littleneed for cooling • Distributecomputationtransparentlybetween the cloud, local servers, desk tops, lap tops and mobile terminals. Wewould like to have high performance and low power consumption. • EfficientResourceUtilization
