It continues, whereas the end to be attained is but an illusion of the climber, as he fares on and on from crest to crest; and once the goal is reached it has no meaning." Antoine de Saint-Exupry, The Wisdom of the Sands UNIVERSITY OF TARTU Abstract Faculty of Mathematics and Computer Science Institute of Computer Science Master of Science Refactoring of ESB-based systems on the cloud by Mariana Kukhtyn Nowadays enterprises are facing new, unprecedented press for competitiveness: the speed of service providing, price of inaccuracy, possibility to use applications from desktops, notes and other mobile devices. These new conditions force business to search for addi- tional resources and configurations for providing better services. Thus, we are arguing to find general hints for uniting enterprises, cloud computing and distributed middleware software in one system in order to fulfill this goal. ESB-based systems and Service Oriented Architecture taken as one of its cases are as- sessed in concern to their possible aplication and profit-usage on the remote servers. In this work, for the first time different vision of distributed ESB-systems (Federated, In- ternet and proper Distributed) are described, prooving that idea is not new but different research groups focus on different features. Statistics data on cloud application is used to object widely-spread statements on cloud security and finance-efficiency.

  • Towards a More Scalable ESB Solution
    Access Point Framework – towards a more scalable ESB solution SANJA JANKOLOVSKA BOSHKO ZHERAJIKJ Supervisor: Don Baldwin, CEO of Aurenav LLC. Examiner: Mihhail Matskin Degree project in Software Engineering of Distributed Systems Stockholm, Sweden 2012 Abstract The aim of this project was to investigate the potential issues of existing ESB products and present how the Access Point Framework (an Enterprise Application Integration Framework developed within Aurenav LLC.), mitigates these problems. For this purpose, the framework was compared with two existing ESB solutions- Mule ESB and BizTalk® ESB Toolkit. In order to be able to present the simplicity of integration with the Access Point Framework, first, it was moved to open source underlying technologies. The two most important ones were the Message Oriented Middleware products –ActiveMQ and RabbitMQ, both of which are interchangeable, depending on the user needs. Additionally, after having the framework fully functional, two simple applications were integrated to exemplify the ease of integration. Currently, the Access Point Framework is synchronous and single threaded, however, the necessary improvements are discussed throughout the paper. The steps described paved the way for carrying out the performance testing that was done on the framework. The project serves mainly as a comparison and evaluation document but also as a base point for moving the APF to an open source solution, while preserving the configurability in order to extend the functionality in later releases. Sammanfattning Målet med detta project var att undersöka eventuella problem med existerande ESB produkter och visa hur Access Point Framework (en Enterprise Application Integration Framework utvecklad av Aurenav LLC.), mildrar dessa problem.

ETH Library COMPLEX EVENT DETECTION ON AN ENTERPRISE SERVICE BUS Master Thesis Systems Group September 16, 2008 – March 16, 2009 Silvio Kohler ETH Zurich [email protected] Supervised by: Dr. Peter Fischer Kyumars Sheykh Esmaili 2 Abstract Service-oriented architectures (SOA) have been adapted by businesses to improve their flexibility, recently with a focus on dynamic outsourcing of business processes. A cor- nerstone of a SOA is an Enterprise Service Bus (ESB), which is used to loosely connect services by the means of message exchange. Businesses using a SOA still need to comply with applicable laws and regulations. To ensure this compliance, the MASTER [12] project supposes a control infrastructure to be implemented as another service in the SOA. Observing the message flow on an ESB provides ample opportunities to observe and compute indicators for compliance. The control infrastructure mentioned above needs to catch raw messages on the ESB to detect complex events and answer queries posed by a higher level infrastructure. The goal of this master thesis is to close the gap between the interface of such a higher level infrastructure (defined by MASTER) and the interfaces provided by exist- ing ESBs. This includes providing an overview of existing Enterprise Service Buses and the interfaces they offer.

    Institute of Architecture of Application Systems University of Stuttgart Universitätsstraße 38 D-70569 Stuttgart Master’s Thesis Nr. 3166 Extending an Open Source Enterprise Service Bus for Multi-Tenancy Support Stefan Essl Course of Studies Information Systems First Examiner Prof. Dr. Frank Leymann Second Examiner Prof. Dr.-Ing. habil. Bernhard Mitschang Advisor Dipl.-Inf. Steve Strauch Dipl.-Inf. Tobias Binz Commencement April 1, 2011 Conclusion November 4, 2011 CR-Classification C.2.4, D.2.11, H.3.4, H.4.1, K.1 Abstract Within the Cloud computing approach, Platform as a Service is a way to provide customers with the capability to deploy acquired or consumer-created applications onto the Cloud infrastructure. It relieves these of the need to install and run their own infrastructure or to manage and control the underlying Cloud infrastructure. Whereas providers of such services try to serve as many customers as possible to exploit economies of scale, especially small and medium businesses profit from this approach, because they can save the high up front and administrative cost of installing and running their own processing systems and applications. In order to offer an Enterprise Service Bus as a proven technology known from the field of Service-Oriented Architectures as a Platform in the Cloud it has to be made multi-tenant aware. This fulfills the Platform as a Service providers’ need to raise the overall utilization and to maximize revenue by serving multiple customers from one system instance. This master’s thesis develops a concept to extend an Enterprise Service Bus by multi-tenancy support with respect to communication and implements this concept in an open source prod- uct.

Valencia, Km 7, 28031 Madrid, Spain; [email protected] (J.-F.M.); [email protected] (P.C.); [email protected] (G.R.) * Correspondence: [email protected]; Tel.: +34-914-524-900 (ext. 20794) Academic Editor: Paras Mandal Received: 30 September 2016; Accepted: 29 January 2017; Published: 10 February 2017 Abstract: The success of the smart grid relies heavily on the integration of Distributed Energy Resources (DERs) and interoperability among the hardware elements that are present as part of either the smart grid itself or in a smaller size deployment, such as a microgrid. Therefore, establishing an accurate design for software architectures that guarantee interoperability and are able to abstract hardware heterogeneity in this application domain, along with a clearly defined procedure on how to implement and test a solution like this, becomes a desirable objective. This paper describes the requirements needed to design a secure, decentralized and semantic middleware architecture for microgrids and the procedures used to develop it, so that the mandatory software components that have to be encased by the solution, as well as the steps that should be followed to make it happen, become clear for any designer, software architect or programmer that has to tackle similar challenges. In order to demonstrate the usability of the ideas put forward here, two successful pilots where middleware solutions were created according to these principles have been described.
