    IT service provisioning by passing hints in module interfaces
    (2012) Naik, N.N.; Veigas, J.P.; Chandrasekaran, K.
    Communication is a crucial aspect in the domain of IT service provisioning, where data is being transmitted from the sending entity to the receiving entity by the interaction of applications via an interface. When the data is transferred, large amount of time is consumed for its computation by the service at the receiving side. When two applications interact via an interface the communication can be made effective by enhancing the IT service provisioning system with inclusion of web services by some faster means. In this paper we discuss how IT service provisioning can be handled by making use of hints using web services that can be passed by the modules within the application via interfaces from a client to the service, which can avoid expensive computation by the service. The hint is passed in its request and if correct, a service can avoid the computation and communication overhead leading to better system performance. If the message or hint is incorrect it leads to erroneous computations. Passing hints between the modules within an application should take place in an effective, non-erroneous way by imparting quality and less computation by the service involved between two communicating entities contributing towards the promises of services provided by cloud computing. © 2012 IEEE.

    Achieving green computing by effective utilization of cloud resources using a cloud OS
    (2013) Naik, N.N.; Kanagala, K.; Veigas, J.P.
    Cloud Computing is composed of amalgamation of different elements and solutions, namely operating systems running on a single virtualized computing environment, middleware layers that attempt to combine physical and virtualized resources from multiple operating systems, and specialized application engines that influence a substantial benefit of the cloud service provider (e.g. Amazon). In this platform, huge amount of resources are present in the cloud and this resources need to be managed effectively. When this resources are united, major problems are incorporated into the system as well as the application due to compatibility and consistency constraints, hence there does not exist a unified processing environment to carry out this operation. In this paper, we demonstrate the importance of cloud OS known as virtual distributed operating system that binds together this cloud resources in a single-unified processing environment that helps to manage the cloud resources in a flexible and accessible approach henceforth enhancing the systems performance. Several cloud OS are available to bridge the gap between this cloud resources. The experiment is being performed on several existing platforms that allows the user to access this resources with a user friendly GUI. By making use of a cloud OS the overhead in handling the cloud resources by the running machine can be successfully reduced for a particular cloud user hence directing towards efficient use of systems resources and contributing towards the features of green computing. © 2013 IEEE.

    A framework to monitor cloud infrastructure in service oriented approach
    (2013) Veigas, J.P.; Chandra Sekaran, K.
    Cloud computing processes and stores the organization's sensitive data in the third party infrastructure. Monitoring these activities within the cloud environment is a major task for the security analysts and the cloud consumer. The cloud service providers may voluntarily suppress the security threats detected in their Infrastructure from the consumers. The goal is to decouple Intrusion Detection System (IDS) related logic from individual application business logic and adhere to the Service Oriented Architecture Standards. This paper provides a framework for Intrusion Detection and reporting service to the cloud consumers based on the type of applications and their necessary security needs. Cloud consumers can choose the desired signatures from this framework to protect their applications. The proposed technique is deployed in existing open source cloud environment with minimum changes. A proof-of-concept prototype has been implemented based on Eucalyptus open source packages to show the feasibility of this approach. Our results show that this framework provides effective way to monitor the cloud infrastructure in service oriented approach. © 2013 IEEE.
