For sales / investor meetings I would like to be able to switch to an offline demo of my web based service. I try to embed my servers on a VM but the result was laggy.<p>What tools / technique are the best?
How about having your client cache the results? I am working on a project that uses an external customer database service, and in order to speed up the service i cache the lookups/REST responses in a 5 min retention speedup cache and an eternal failover cache that allows us to continue to function if the external service goes offline. I use Ehcache.
