Re: Fault-tolerance in web services


fault tolerance soap
Indeed, not naive at all. Load balancing and 
scalability issues are here already in WSRP, and 
will need to be taken into account by IT 
architects as they begin to fashion portal-based 
IT solutions end to end of an enterprise. 
Although heterogeneous environments can be 
accommodated, the tier of largest companies will 
almost certainly need to rethink IT strategies in 
terms of investing in the most efficient and 
scalable systems. That is going to be more 
efficient with systems designed to scale from day 
one AND work with more heterogeneous partners. 
Not easy. Not simple.

Ciao,
