Lessons from Andy Bechtolsheim

Andy Bechtolsheim co-founded Sun Microsystems and Arista Networks by solving the physical and economic bottlenecks of computing through simple, open standards. While famous for writing Google’s first $100,000 check, his more enduring skill is a disciplined eye for identifying the next leap in technology. These lessons break down his framework for designing systems and spotting the next shift in the market.
