Dealing with Scale and Adaptation of Global Web Services Management

Abstract

Service Oriented Architectures (SOA) are becoming the prevalent approach for realizing modern services and systems. SOA offers superior support for autonomy (decoupling) and heterogeneity compared to previous generation middleware systems, resulting in more scalable and adaptive solutions. However, SOA have not adequately addressed management, while traditional management solutions do not sufficiently scale to address the needs of (global) Web services. We propose scalable management based on models and industry standards. We discuss a use case for global service management and present its design, implementation, and preliminary evaluation. We retain all the benefits of SOA while also enabling global scale manageability. Our approach provides manageability that is comprehensible for administrators yet automated enough for integration into autonomous systems.

Criação e Gerenciamento de Composições de IDSs

“…A análise do mecanismo de gerenciamento de composições em escala global baseado em Grids, proposto por [Vambenepe et al 2005], usando um workflow BPEL, também foi bastante útil para o desenvolvimento do processo de composição de IDSs. Apesar de não fazermos o uso de Grids, nossa proposta também pode ser aplicado em tal ambiente.…”

Stakeholder Identification and Analysis for Service Lifecycle Management

“…Service lifecycle management is crucial to achieve higher quality and enhance the autonomy and heterogeneity of SOA based systems (Vambenepe et al, 2007). As such it has been attached much importance and different definitions and explanations can be found in the literature.…”

Towards Dynamic Reconfiguration for QoS Consistent Services Based Applications

“…To the best of our knowledge, it becomes an additionally urgent challenge how to adjust service based applications to meet highly dynamic environments (e.g. in a clouding environment) and fast changing business requirements [4,5,9,10]. Up to now, although there existed many valuable works, most of them focus on providing essential services and functions in the presence of runtime environment changes [6][7][8][9].…”
