  • Overview
    • We invite for contributions on scalable solutions for Service Oreinted Infrastructures (SOI). The emphasis is on clustering approaches that scale-out - that is, that by adding additional sites to a cluster, the cluster is able to cope with higher loads (e.g. higher number of concurrent clients). We look for scalability approaches to single and multi-tier architectures with special emphasis on stateful and/or transactional services. Scalability approaches in the context of new SOA paradigms is also sought such as Cloud Computing, SaaS, …
  • Problem Statement

    • Current approaches to provide scalability for SOI rely on scale-up approaches, that is, buying a more powerful mainframe for dealing with higher loads. In here, solutions to provide scalability based on scale-out approaches are sought. Scale-out approaches rely on clusters that by growing with additional sites are able to cope with higher loads. We expect contributions on the scalability for systems with single and multiple tiers. Proposed approaches are expected to deal with consistency issues, consistency/cost trade-offs, autonomic aspects such as self-provisioning.
      Contributions on systems modelling for predictable performance and scalability are also welcomed.

      Contributions on new paradigms to scalable SOA are also called for, such as Cloud Computing, Software as a Service, Data Streaming, Complex Event Processing, Cluster Computing, Web farms, Edge Computing, …
  • Scope

    • Contributions on scalability approaches to SOI are welcomed. Targeted servers include the typical tiers of multi-tier systems, web server, application server (e.g. J2EE) and databases. Scalability for servers in the area of web services, service composition, etc. are also in scope, as well as scalability approaches for new service paradigms as Cloud Computing, Software as a Service, Data Streaming, Complex Event Processing, Cluster Computing, Web farms, Edge Computing, …

      Hardware based scale-up solutions are out of scope.
  • Contributions
    • The contributions can take the form of
      1. Architectural patterns for attaining scalability in SOI
      2. Specification of SOI interfaces to enable scalability solutions
      3. Addressing scalability issues in SOI standards at the architectural level.
  • Baseline
    • The baseline is composed of web service stack (W3C, OASIS), and supporting multi-tier SOI standards such as the J2EE framework.
