this week we got a call from one of our customers using our web content management system SIT Portal DXP as the base for their web portal based on Domino. They were asking for a new sizing for their primary web server that was "... getting a little bit slow..." over the past months. To get some insight on what's happening at the server, we took a look at the web stats and I think they are quiet remarkable. The customer had consistently expanded the website to now 60 portals and a couple of thousand landing pages and it is still running on one Domino server !
Oh, and did I mention that this poor little server also is the web mail gateway for 500 internal users ?
Now, to be clear - that's not an environment that we recommend for a site of that size but it clearly shows how capable a Domino web server is in a real world scenario. The server is a virtual linux box, 2 virtual processors, 16 4 GB RAM, managed by one part time admin who also does content management in the overall portal environment. The portal is bootstrap based fully responsive, etc... .
* Update - I stand corrected: the server had only 4 GB of RAM until Monday of last week. Then, my colleagues decided that it was about time to ease the pain a bit immediately.
Compare that to other web application servers - can you grow your infrastructure to that size using one machine ? I doubt it in a lot of cases and from an availability and load balancing aspect you would not do that. And of course we will be considering all of these aspects in the new sizing - the customer started small seven years ago and never had the desire to upgrade until this year and I guess by looking at the numbers here, that totally makes sense. We will also put a reverse / cache proxy up to reduce the load even more and taking the SSL burden away from Domino as well.
Can't wait to see this baby run with all the enhancements mentioned above :-).
