"Economic advantage" can be hard to define but we'll try.
eValid is first and foremost a productivity tool.
The goal is to get more done with less time and effort and
with better effect using eValid compared with other tools or
approaches/solutions.
So the costs of your effort, your computer time, you team
time, have to be weighted along with the costs of access
(license or lease or subscription).
We don't think it's appropriate to get into pricing details
here, but we know of one server loading solution that will run
in the $20K to $100K for a solution that simulates 1000
Virtual Users (VUs), whereas eValid's costs are about 10% of
that for 1000 Browser Users (BUs).
If you have been following this forum for long, a BU is an
eValid playback emulating a real user -- hence the term
"Browser Bser". The main point of a BU is that the server
cannot tell it is NOT a real user out there on the client
browser.
A virtual user or VU is an HTTP simulation of the traffic that
a user generated at some time in the past. Because of the
technology used in HTTP based playbacks, you never quite have
the same realism you get with an eValid REAL browser based
playback.
So, here the economic advantage is a combination of price,
quality, and ease of use.
Oh, the $1/browser-hour phrase refers to the cost of
sustaining one browser repeatedly running the same script for
one hour. In the load-testing community, the $1/browser-hour
cost has become something of a threshold: Above that and
you're too expensive, and below that, well, you probably don't
have a real BU.
