Most of the current disaster recovery solutions need to rely on expensive commercial disaster recovery software and hardware. In order to reduce the cost of disaster recovery, a fully featured, affordable disaster recovery solution and an offsite disaster recovery system RDRS (Remote Disaster Recovery System) are putted forward in this paper. Based on existing technologies, such as DFS, database mirroring and IP address drifting, the RDRS is completed without introducing expensive commercial disaster recovery software and hard-ware. Tentative results show that, facing varieties of failures, this solution and the RDRS can effectively conduct disaster recovery. In General, this solution and system are fully able to meet the requirements for most disaster recovery project plan, low-cost and strong-security. [ABSTRACT FROM PUBLISHER]

Research in service-oriented computing traditionally struggles with the absence of public cases and data sets for evaluating and comparing research results. This is particularly evident for QoS-aware service-based computing, where public and widely accepted QoS traces would help to strengthen the fair comparison of QoS-aware automated composition and QoS prediction approaches. In this paper, we present one public data set produced for the evaluation of a contribution to the IEEE Transactions on Services Computing journal. We briefly introduce the background story of the use case and describe our monitored data set. We hope that this data set can serve as a basis for evaluation of future research papers from other authors. [ABSTRACT FROM PUBLISHER]

Software-as-a-service emerges as a new delivery model for the software development and applications. In multi-tenancy applications, tenants can customize and adjust the corresponding services shared by tenants based on their business requirements with strong elasticity and expansibility. As services do not exist independently, the resolving of service dependencies in practical multi-tenancy applications is of great importance. In this paper, we propose an Extended Dependency-aware Hierarchical Service Model (EDHSM) to visually describe hierarchical services and service dependencies. We employ a directed hypergraph to represent the model and resolve service dependencies. Moreover, we apply the service dependencies resolving to dynamic service deployment in optimal placement of tenants and online service migration based on load monitoring for multi-tenancy applications. So application systems can be built quickly and operated stably at a low maintaining cost. [ABSTRACT FROM PUBLISHER]

Audits are performed to ascertain the validity and reliability of information, also to provide an assessment of a system's internal control. Analyzed here is an incremental design of unified auditing and monitoring platform (UAM) in view point of business software. In fact, UAM is an integrated managing system of logs and running parameters. Database is the core of all kinds of management information system (MIS), and the more business logic implemented in database, the less coding work left to programmers. In this paper, complex network is introduced into the database table designing to visualization the internal associations which denotes the external business logic relationship. Though an example is discussed, but the approach can be widely used in various MIS system design, especially in large scale information system. [ABSTRACT FROM PUBLISHER]

Cloud infrastructure services offer elastic computing resources that particularly match the requirements of web transactional applications. Such applications, e.g., e-business applications, have high business value and variable workload patterns and therefore utilizing such elastic cloud resources in a cost-effective way is crucial need for cloud consumers. Defining economic elasticity rules, however, is not trivial as it requires (i) running considerable number of experiments with different parameters/metrics and workloads (ii) collecting appropriate cloud and application cost/performance measurements and (iii) performing cost/performance trade-off analysis. In this paper we introduce our on-going work on elasticity economics platform that supports cloud consumers to achieve the above three requirements. We also discuss the key elements of the elasticity economics platform and our early prototyping experience. [ABSTRACT FROM PUBLISHER]
