Hi All,
What is diffrence between Cognos 11 Architecture VS Cognos 10 Architecture ?
As per my understanding Web server is optional - I want to understand more on this
Also let me know it there any changes in Cognos 11 Architecture
Thanks,
Nag
Hi,
Fundamentally they are the same architecture. Cognos Analytics has some new pieces that didn't exist in Cognos 10, and these use a REST interface rather than the old XML interface (eg the new portal, dashboards, storyboards, data modules, explore etc). These use largely client-side processing for the UI.
A web server has always been optional - even in Cognos 10. You have the option of using the inbuilt servlet gateway instead. For Cognos Analytics the web server config is different than in Cognos 10 as it now requires URL redirect rules.
The one thing to watch that is different is load balancing. The parts of the architecture using the older XML interface (eg reports) will still load balance as they did in Cognos 10, but this isn't the case for the new REST interface pieces - you will need to use Routing Rules if you want to spread the load more evenly across multiple servers.
Cheers!
