There seems to be more to Andrew Feldman's departure. He would have been the logical choice to head the dense-server BU. It appears they don't have anyone in that position and Lisa is handling it herself?
The sea-micro acquisition always seemed perplexing. AMD has been a server cpu company and for it to be selling systems has always been odd. This might mark the end of that experiment.
When a company is acquired, it is common to have the existing management sign a one to two-year contract as part of the buyout agreement. After that agreement expires, it is common to see the founders leave the company with their full bonus and payout rather than stay for a reduced salary. So, I wouldn't read too much into Mr. Feldman's departure.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
