a provider of web infrastructures and applications for companies that
require scalable, high-performance, mission critical solutions, today
announced it provided strategic consulting services and developed an Apache
Traffic Server plugin for Oregon
Health & Science University (OHSU).
As part of the project OHSU contributed the Apache plugin back to the Open
Source Community so that other companies can now benefit from the
functionality it provides. The plugin accommodates for
"stale-while-revalidate" and "stale-if-error" cache control extensions,
reducing latency and improving content serving consistency.
OHSU is a leading health and research university that strives for
excellence in patient care, education and research, and community
service. It cares for more than 235,000 patients each year from around
the region and takes a leadership role in contributing to solutions
involving the health of the state and the nation, such as health care
access and transparency, ethics and workforce shortages.
OHSU mde a strategic decision to proactively enhance the site's
performance in preparation for traffic bursts that would drive traffic
to the site at higher than normal levels. The OHSU site gets about
500,000 page views per week, and as the leading provider of complex
medical care in Oregon, they could see similar numbers in a single day
if the city or region experienced an unscheduled emergency. OHSU's Web
Strategies team decided that a web accelerator solution would best meet
its needs, and after much research and competitive performance analysis
decided upon Apache
Originally developed by Inktomi, and later acquired and open sourced by
Yahoo!, Apache Traffic Server (ATS) is one of the leading open source
caching proxy servers available today. The web strategies team then
turned to OmniTI, known in the industry for its ATS expertise, for
guidance on how to implement ATS and to develop a customized plugin for
"stale-while-revalidate" and "stale-if-error" scenarios.
"The plugin that OmniTI built has filled a hole in Apache Traffic
Server's functionality," said Brendan Webb, a web engineer at OHSU.
"OmniTI's experience with reverse proxies, and specifically ATS, helped
us better understand exactly what steps were required and what pitfalls
to avoid during both our initial implementation and when it came time to
develop the plugin."
ATS and the plugin have now been implemented on OHSU's entire intranet
and on sections of the public site. The OHSU intranet serves more than
13,000 employees, and the plugin has added a layer of redundancy in case
there are errors on the site. Now the web staff can see where the errors
are and fix them, while end users don't experience any disruption in
content or performance.
"OHSU is an innovative institution that is being proactive by improving
web services performance with ATS," said Leon Fayer, vice president of
business development, OmniTI. "We are happy to have joined forces with
them to deliver a high performance solution that meets their needs for
today and the future."
Health & Science University is the state's only academic health
and research university. As Portland's largest employer with nearly
14,000 employees, OHSU's size contributes to its ability to provide many
services and community support activities not found anywhere else in the
state. OHSU serves patients from every corner of Oregon, and is a
conduit for learning for more than 4,300 students and trainees. OHSU is
the source of more than 200 community outreach programs that bring
health and education services to each county in the state.
