Improving Availability on the
Internet
This section contains an overview of open standards that may be used in conjunction
with existing HP application software services to provide applications, running across
the Internet or private networks, with all of the unique HP NonStop server attributes
such as availability, scalability and manageability.
The following topics are covered:
•
Open Standards - how the use of standards promotes productivity backed by
NonStop fundamentals
•
The Pathway Application Server - a mix of TS/MP, iTS and NonStop SOAP
•
The iTP Secure WebServer - the HP version of an open standards web server that
is supplied at no cost
•
The WebLogic Server - the BEA web server that may be purchased to run on
NonStop servers
Open Standards
The HP NonStop server has evolved over the years to fully embrace open standards in
both hardware and software. This evolution ranges from microprocessor choice to
coding languages, middleware, networking, and storage. The use of standards
provides numerous benefits from lowering development costs through reusable
components and consistent implementations to increasing the ability to make changes
by enabling coding productivity.
There are several categories of standards:
•
Open standards that have a specification and are governed by a standards group
•
De-facto standards - Industry standards that are commonly agreed upon by a
predominant set of vendors
•
Open source in the public domain - popular software that is being quickly adopted
by large numbers of users
If you develop applications using such standards on NonStop systems the benefits are
multiplied because the HP platforms provide the NonStop fundamentals at little extra
cost. Programmers can focus on the business logic and transaction boundaries while
the NonStop server takes care of the fundamentals of availability, scalability, data
integrity, and system manageability.
