I would like to get your real time experience and feedback on multiple web-engines on single application servers.
In our site, there are excessive number of web-service transactions, to handle the traffic we have different set of the application servers, specific to providing web services.
Application Server - 1
Application Server - 2
Application Server - 3
Application Server - 4
Application Server - 5
Application Server - 6
1,2,3 application servers are exposed to web users and 4,5,6 are specific to providing web-services.
Now, I would like create multiple(more than 2) CA SDM web-engines on single application server, before doing it would like to know the Pros and Cons of having multiple web-engines on single application machine.
Venkat, in AA env, if you expect a lot of traffic to the app server, definitely you would need to consider adding more webengines to the app server. I can see the pros as more workload can be handled and the cons? you may need to
consider the following:
--more network bandwidth from the app server to the database server and between the bg server with all app servers
--more app server resources would need
--the end users now have two urls to access the app--pdmweb.exe and pdmweb1.exe(assuming you add another webengine)--and end users may just go to the first one as you used to be, though you tell them to use the second
one. So you may need to add a webdirector and publish its url as pdmweb_d.exe for all webengines
I am sure there should be more out there so hope others add to this discussion. It is a very good one. Thanks _Chi
