3. Can Web Servers Do TP?

ODBC
SQL
IIS
= Web
7,000 Web clients
Pool of
DBC links
All Microsoft TPC benchmarks done with Web server (IIS) as TP monitor.
Uses HTTP as wire protocol, ODBC as local protocol
Gets GREAT! Performance (~2KtpmC/cpu)

4. Objects! Desktop development Drag & Drop deployment
Scripting work flows with VBScript or JavaScript
Server shell does all the voodoo
configure
load balance
authenticate/authorize
thread pool

5. Prediction: The next big event
Microsoft, Netscape, Oracle, and others will unify
ORBS and
Web Servers and
TP monitors
Stored procedures (TP lite)
Results will be “rough” at first, but they will mature quickly
