Building Security into a Service-Oriented Architecture White Paper»rank: 2966193by: ZapThink, Jason Bloomberg
: :Service-oriented architectures (SOAs) based upon Web Services are an evolutionary improvement upon existing IT architectures, primarily because these SOAs offer loose coupling between Service producers and consumers. Loose coupling refers to a level of independence between the participants in a Web Services interaction that allows them to interact on their own terms, without requiring substantial changes on one system when the other changes. Such loose coupling enables an enterprises IT infrastructure to be agile in the face of change.Loose coupling, however, while simple to understand, is complex to implement. There ... |

Context & Identity White Paper: The Linchpins of Web Services Security»rank: 2966193by: ZapThink, Jason Bloomberg
: :Enterprise identity and access management capabilities are a fundamental prerequisite for the implementation of mission-critical Web Services, because such Services provide a layer of abstraction that hides the complexity of underlying technology while at the same time providing increased value to the business user of those Web Services. Such an abstraction layer, however, can lead to the loss of security context, where the information about the identity and access privileges of a requester of a particular Service may be lost to the underlying applications that provide the data and functionality ... |

High-Performance Information Aggregation Using XML-Based Operational Data Servers White Paper: Empowering Flexible Data Aggregation in the Financial Services Markets»rank: 3476643by: ZapThink, Ronald D. Schmelzer
: :Financial Service Providers are essentially information-based businesses: their primary asset is the information they store and share. These companies are struggling today with finding the most flexible and cost-effective means to integrate and aggregate information from a wide range of unstructured and semi-structured enterprise data sources. Todays integration solutions are either targeted only at structured sources of information such as databases, or are too rigid and expensive to handle enterprise information integration and aggregation needs. Furthermore, the unique requirements of Financial Services firms for real-time, scalable access to disparate information ... |
The Value Proposition for Service-Oriented Integration White Paper: Using Web Services and Service-Oriented Architectures to Facilitate Internal and External Integration»rank: 5041045by: ZapThink, Ronald D. Schmelzer
: :Connecting systems both within the enterprise and among suppliers, partners, and customers is of critical importance to todays enterprise. However, integration remains complex, expensive, and risky. The increasing movement toward data virtualization, B2B systems, and legacy reuse is driving a need to integrate dozens, if not hundreds of systems in a single environment. The end result is a tangled web of point-to-point integrations that becomes increasingly brittle over time. The costs for both maintaining and changing systems can become exorbitant, since changing requirements necessitates manual recoding of applications. Enterprises are ... |

The Complete Vision of Service-Oriented Enterprise Management White Paper»rank: 6076271by: ZapThink, Ronald D. Schmelzer, Jason Bloomberg
: :Companies have long been striving to meet two critical goals in their enterprise: how to make their existing systems work better together, and how to gain critical visibility into how their various processes and systems are contributing to overall business goals. Into this arena, Service-Oriented Architectures and Web Services are introducing the concept of standards-based, loosely-coupled integration to help solve the first problem of managing intractable business integration problems. At the same time, these approaches lend themselves particularly well to providing greater visibility into business processes and system performance. Traditionally, ... |
Events vs. Services: The Real Story White Paper: Best Practices in Event-Driven SOA»rank: 2451719by: ZapThink, Jason Bloomberg
: :Service-Oriented Architecture (SOA) is an approach to distributed computing that considers software functionality as Services on the network. Event-Driven Architecture (EDA) is an approach where events trigger asynchronous messages that are then sent between independent software components. Some people think that these two approaches are different, alternative takes on distributed computing, but thats not correct. In fact, SOA supports a variety of interactions, many of which are event-driven. To truly understand the power of SOA, its important to keep in mind that SOA represents an abstraction layer that masks the ... |
