Jan programmed easy rest server application which emulates ArcGIS REST-JSON interface and search point-layer very, very quickly. :-)
About 3 milions street names with numbers within 0.001 second per query. There is a posibility to speedup searching a lot below this time.
Nearly unlimited users can use this service :-) because clustering is easy.

This service is in very alpha state but fully functional and deployed on my main website janforman.com.

Jan is now thinking about big hybrid comunication model based on Enterprise Service Bus and HTTP REST services that can bring best availability and performance :-) for Mission Critical Applications. Main servers with data storage are connected by Enterprise Service Bus, clients communicate with those servers and other Services (technological actions) by REST API. This design is very flexible and simple together.
Schema of this idea coming ASAP…

Today i was testing simple content delivery network (CDN). it’s implemented on high-level in application layer and uses reverse proxy (with temporary storage). Network ranges are cached in main database and selected while request is being processed.
Schema is very easy and there’s no exact limitation about number of users and nodes.

Jan is now thinking about integration of vimeo.com and youtube.com into janforman.com as second and third video source.
(not because of their quality ;-) but for quicker and legal video integration). my first idea was easy – mixed or selected source that user can choose yourself.
