A techie walks us through healthcare.gov's two big problems

Jyoti Bansal is the founder of AppDynamics, an application management company that, among other things "makes sure essential software applications of customers such as Netflix stay up and running." I gave him a call to talk about some of the technological challenges that have plagued HealthCare.Gov during its first week online, what's causing those problems, and what he would change if put in charge of the project. What follows is a transcript of our conversation, lightly edited for clarity.
