Temat: Architektura SOA
Mówi się o tym coraz więcej. Jest w tym też jednak, moim zdaniem, wiele hałasu o nic, wiele nieporozumień i wiele nieuzasadnionych oczekiwań. SOA (Service Oriented Architecture) to metodyka postępowania, projektowania itp. ale nie technologia.Uważam, że pomaga systematyzować projekty IT ale nie jest żadnym narzędziem. Poniżej bardzo ciekawy cytat .... choć ja nie demonizował bym tych webserwisów...
Service Oriented Architecture
The goal for a SOA is a world wide mesh of collaborating services, which are published and available for invocation on the Service Bus. Adopting SOA is essential to deliver the business agility and IT flexibility promised by Web Services. These benefits are delivered not by just viewing service architecture from a technology perspective and the adoption of Web Service protocols, but require the creation of a Service Oriented Environment that is based on the following key principals:
Service is the important concept. Web Services are the set of protocols by which Services can be published, discovered and used in a technology neutral, standard form.
SOA is not just an architecture of services seen from a technology perspective, but the policies, practices, and frameworks by which we ensure the right services are provided and consumed.
With SOA it is critical to implement processes that ensure that there are at least two different and separate processes—for provider and consumer.
Rather than leaving developers to discover individual services and put them into context, the Business Service Bus is instead their starting point that guides them to a coherent set that has been assembled for their domain.
