The Role and Benefits of HP WebQoS
HP WebQoS is an enhancement to your operating environment that
stabilizes, optimizes, and prioritizes Internet-related applications and
transactions that run on Windows 2000 and NT servers (Windows) and
SPARC
1
servers (Solaris
1
operating environment). HP WebQoS works
with web-enabled applications built on top of the iPlanet Web Server
1
version 4.1 (UNIX®) and Microsoft® IIS
2
(Internet Information Server)
version 4.0 (Windows NT) and version 5.0 (Windows 2000).
HP WebQoS enables you to use your resources efficiently to deliver
predictable and differentiated service levels for your web-based
applications, based on the type of customer or transaction. It allows you
to determine these service levels based on business policies.
Although the Internet represents significant opportunities for expanding
your business, the following risks may hamper your ability to deliver
web-based services to customers and partners reliably:
• Unpredictable and possibly fluctuating demand for services.
Because the Internet offers instantaneous access to your site,
promotional, seasonal, or current events may instigate sudden and
immediate interest in your services. Although the additional interest
and business may be welcome, your server may not be able to handle
the load if significant numbers of clients come all at one time. Or if
you are a service provider hosting multiple sites on one server, you
should make sure that the demands of one site do not restrict use by
other sites on the same server.
• Heavier than expected system processing per user request.
The actual workloads exhibited by each visitor to your site may not
align with the workload models you generated during the capacity
planning stage. Perhaps users are performing far more searches than
you anticipated or are spending a lot more time performing compute
intensive operations while at your site.
