INTRODUCTION
Extreme Transaction Processing - What & Why
Extreme Transaction Processing (XTP) is an exceptionally demanding form of transaction
processing. Transactions of most high-end (more than 10,000 concurrent accesses
or 500 transactions per second) or ultra-high-end (more than 100,000 concurrent
accesses or 5,000 transactions per second) requirements or more would require
this form of processing.
Gartner defines XTP as an application style aimed at supporting the design,
development, deployment, management and maintenance of distributed TP applications
characterized by exceptionally demanding performance, scalability, availability,
security, manageability and dependability requirements.
Very much like traditional TP systems, XTP applications are aimed at enabling
efficient, reliable concurrent and real-time access (read/update) to a shared
database by executing application programs commonly referred to as "transactions."
The first and foremost adoption of XTP can be observed amongst the financial
institutions (a one-millisecond advantage in trading applications can be worth
$100 million a year to a major brokerage firm, by one estimate), whose prime
requirements are more processing capability, but without requiring exponential
increase in hardware costs, in areas such as fraud detection, risk computation,
and stock trade resolution, to profit from minute, fleeting price anomalies
and to mask their intentions via "time-slicing," or carving huge orders
into smaller batches so as not to move the market.
What is Federated ESB (Enterprise Service Bus)?
Federated ESB (FESB) provides the ability to use multiple service registries
and administration domains while mapping the disparate registries into a federated
set of services. The federated ESB facilitates service interactions with multiple
ESB implementations. One master ESB to which several dependent ESBs are federated
to provide a subset of services that are applicable throughout the enterprise.

This conference will teach business leaders what to expect, and what to avoid, to make their SOA journey a success. SOA is a long journey, not a single project, and distributed architectures are inherently complex. Success requires new ways of working, creating more efficient cross organization processes, adopting new tools, and building new skills.Register

A lot of people are talking about Enterprise 2.0 as being the business application of Web 2.0 technology. However, there's still some debate on exactly what this technology entails, how it applies to today's business models, and which components bring true value.
