Velocity Software, Inc. is recognized as
a leader in the performance measurement of z/VM and Linux on z.
The Velocity Performance Suite consist of a set of tools that
enable installations running z/VM to manage Linux and z/VM
performance.
In addition, many components of server farms can be
measured and analyzed. Performance data can be viewed real-time
through the use of either 3270
or a browser.
The CLOUD Implementation (zPRO) component is designed
for full cloud PaaS implementation as well as
to extend the capabilities of the z/VM sysprog (system programmer)
to the browser world. This feature moves system management to
the point-and-click crowd. Archived data and reports can be
kept available of long term review and reporting usine zMAP.
The zVPS, formally ESALPS, components consist of:
zMON (formally ESAMON - real-time display of performance data),
zTCP (formally ESATCP - SNMP data collection),
zMAP (formally ESAMAP - historical reporting and archiving),
zVWS (formally ESAWEB - z/VM based web server),
zTUNE (a subscription service),
zVIEW (formally SHOWCASE - web based viewing of performance data),
zPRO (new to the quality line of Velocity Software Products).
Velocity continues to work with other software vendors to ensure
smooth interface with or from other products such as
VM:Webgateway, CA-Webgateway, EnterpriseWeb, MXG, MICS.
Velocity software remains the leader and inovator in the
z/VM performance, Linux performance, Managing cloud computing
arenas.
zVWS - Velocity Software's very fast z/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.
We believe this product is up to
30 times faster
than it's previous z/VM platform competitors, and at less cost.
Products that make price performance
improvements measured in orders of
magnitude significantly increase your potential
applications.
Installations with zVPS already are fully licensed for zVWS.
Our objective is to ensure that you can't afford not to run zVWS.
The following lists available features. Upgrades are FREE for licensed users.
Following are some of the features of zVWS provided to meet
the requirements of a general purpose web server:
Fast Web Server: Performance was NOT
an afterthought!
zVWS is written in
assembler making it truly fast and greatly reducing
CPU resource requirements. An internal
cache is provided to eliminate I/O. Persistent connection, part of HTTP
1.1 is supported to reduce the TCPIP stack CPU time requirements.
Status 304 is supported.
The browser
can send a request for a file and request that it be sent if it
has been modified since a particular date. If it has not been
modified, a status 304 is sent back with no data. That tells the
browser to use its cached version, saving having to transmit
data the browser already has in it's cache. The zVWS program is small! Currently
about 700K, this program does not require significant amounts of
storage. The result is a much
higher capacity web server in terms of the number of
hits you can support. You may find that this web server pays for itself just in CPU
savings.
Developed by the VM Performance
Experts:
This web server is developed to meet
extensive performance goals by people that understand
performance. zVWS will be continuously enhanced, with more
function being added, just as our other products are
continuously being enhanced. Be assured that every effort is
being made to make this server FAST!
Multi-home hosting:
If you have a need to support multiple domains from one IP address,
no problem. Each domain can have it's own directory, with no limit
to the number of domains you can support.
Multiple domains directed to a single IP address can be
served by a single set of web server virtual machines "listening"
on a single TCP/IP port.
This relieves an installation from having to
acquire bunches of IP addresses for each domain, (re)configuring
TCP/IP to recognize and route the various IP addresses and
having different domains on separate "non-standard"
ports.
Standard Socket Interface:
There are no special software or hardware requirements for zVWS.
Only standard TCPIP interfaces are used.
TLS/SSL Support:
In cooperation with the z/VM TCP/IP stack, SSL support is easily
configured for additional security.
Full Security:
Security is controlled by IP address and/or by UserID and
password. Security is at the directory level, providing you with
the ability to protect each individual directory's files, even
controlling access to users coming from specific identified
locations.
CGI Support:
CGIs are written with a very simple REXX interface to allow you to add
logic to your web site, or an interface to your data.
We also have a
web interface to zMON that you can check out.
Our web based packages (zPRO, zVIEW, and zPORTAL) all make
extensive use of CGI support in zVWS.
Low Cost of Operation:
Not only is zVWS so fast that it
significantly reduces your processor resource requirements to
run a web server on VM, it is priced just as low.
Ease of Installation?
Installation of zVWS is VERY EASY!
If there is a feature you need that is not on the list, and

A 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.............."
