I thought it strange that HealthCare.gov was released into the wild and promptly fell flat even though a few people were able to sign up. That indicates scalability problems rather than faults in algorithms and data-structures.
“HealthCare.gov was originally planned to handle 50,000 concurrent users, and will reach that capacity by Saturday, the White House official said.
However, big spikes in traffic — such as the 200,000 who tried to get on at the same time on October 1 — would cause users to go into a queue to receive an e-mail advising them when to return, the official said.”
Chuckle. It’s amusing that politicians and their political machines promote something and then are surprised that the system gets overloaded. The scalability should have been there on Day One (in excess, to handle a predictable spike in clients and spammers). Perhaps the Republicans constantly nagging over the budget had something to do with that…
