5. Load Balancing
At the launch of healthcare.gov, 60,000 visitors were expected but instead 250,000 visitors were received, causing poor load balancing, said Khan.
"You can blame the people managing health.gov but the hosting provider failed on the customer with that piece," said Khan. "A consultative approach would have helped to design a system that can scale, spin up additional servers and balance out the traffic. Everybody should think about low-testing their applications if they want to reach a massive scale."
