The Adaptive Enterprise
Adaptive Enterprise is about leveraging IT to not only support change, but to embrace
it. It’s about driving business strategy and business processes into the underlying
applications and IT infrastructure to fuel business success.” An Adaptive Enterprise
dynamically links IT and business strategy so that IT is automatically driven by
changing priorities. As a result, you gain an IT foundation that is an enabler for
business change.
HP’s Adaptive Enterprise real-time enterprise solutions (or simply “real-time solutions”)
are aimed at supporting business processes in a real-time manner in order to capitalize
on change for a competitive advantage. With a real-time solution, an enterprise has
immediate access to current information throughout the entire enterprise and can
respond appropriately to that information.
Real-time solutions are based on zero latency enterprise framework architectures. As
you will see later in this section, the NonStop system constitutes the center, or “hub”, in
an HP zero latency enterprise framework. Subsequent sections explain how the
NonStop hardware and software components combine to fulfill the stringent
requirements of a real-time solution.
The remainder of this section introduces the zero latency enterprise framework and
gives an overview of the components that constitute a zero latency enterprise
framework architecture. The remaining sections show how NonStop systems provide a
unique software and hardware solution to the requirements of a real-time solution:
•
Section 2, Requirements of Real-Time Solutions describes the requirements that a
real-time solution imposes on a computer architecture.
•
Section 3, The Application Server Environment, Section 4, The Relational
Database Management System, and Section 5, Transaction Management,
describe the NonStop application integration and development environment and
explain the functions of the key products that make up this environment: the HP
application server frameworks, the HP NonStop SQL/MX database management
system, and the HP NonStop Transaction Management Facility (TMF).
•
Section 6, The NonStop Operating System and Section 7, Integrity NonStop NS-
Series Server Architecture, describe the software and hardware architecture of
NonStop systems and show how this architecture is especially suited to support
the stringent requirements of a real-time solution.
Note. Although NonStop systems are suited for many other solutions, this manual focuses on
the use of these systems in real-time solutions because of the importance of these solutions in
today’s business environment and because, with their extremely heavy demands, HP real-time
solutions provide an excellent means of illustrating the benefits and advantages of NonStop
systems.
Note. In this manual, the term “application server” has a different meaning from the
traditional meaning of “the server on which applications run.” The term is used here to
refer to a software component that provides a particular set of services.
