zVWS (Formerly ESAWEB)

A Very Fast VM Web Server


z/VM needs a web server than can compete in performance with other platforms. That is Velocity Software's intention in delivering zVWS.

zVWS beats CA's VM:WebGateway TM

We believe this product is up to 30 times faster than it's z/VM platform competitors, and at less cost. Products that make price performance improvements measured in orders of magnitude significantly increase your potential applications.

And zVWS is priced to be competitive. Installations with ESALPS already are fully licensed for zVWS. Note that this site is running zVWS on a P390 under z/VM. And has been since July of 1999.

Our objective is to ensure that you can't afford not to run zVWS. The following lists available features and when they became available. Upgrades are FREE for licensed users.


CA-VM:Webgateway to zVWS Conversion Utility

As the CA product, VM:Webgateway is no longer enhanced or marketed, installations looking for a z/VM based webserver can use the Velocity Software conversion utility to convert CGIs written for VM:Webgateway to operate with zVWS.


With the introduction of Release 4.1.0.0, ESAWEB was rebranded as zVWS

A customer comparison to VM:WebGateway

"First of all I would like to say, that I'm quite impressed by the good
performance of zVWS compared to the web-server product we are currently using (VM:WebGateway from CA). If it is indeed 30 times faster than alternative VM based web-servers, as you claim, is maybe too optimistic, but it certainly is fast. And the price is very attractive too. I'm also delighted by the simple and fast way to access HTTP header variables and POSTed arguments/variables in CGI programs. This is done in a rather clumsy way in VM:WebGateway. My conclusion is, that we would most certainly be interested in buying zVWS as a replacement for VM:WebGateway, both to speed up our web services (that would make our users very happy!) and to lower the overall CPU utilization of our web operations."

Another Customer Testimonial

"Hi guys,

Well, I did the absolute minimum required to get this running................

1 x userid - zVWS
1 x 2 cyl minidisk (would have fit on 1)
1 x zVWS Configuration file change
2 x SFS authority changes
2 x TCPIP profile changes

and my web site is now being served by zVWS! It only took about 15 mins! And it is significantly faster than the Sterling product I was running.................Thank you very much.............."
