July 23, 2012 was a big day for VMware. It was the day the company, which up until then had been known mostly for bringing server virtualization to the enterprise, entered the networking market. By spending $ 1.26 billion to buy startup Nicira, VMware got something else too: Martin Casado, considered one of the forefathers of the software defined networking movement.
Fast forward to Feb. 24, 2016 and it was another big day for VMware. It was the day Casado left the company for a position at Venture capital firm Andreessen Horowitz. Thrust into the spotlight to replace Casado on the day of his amicable departure was Rajiv Ramaswami, a former executive at Broadcom and Cisco who now leads VMware’s networking and security business unit. This week at VMWorld in Las Vegas Ramaswami and VMware’s network virtualization product, NSX, took center stage.
