Joining Stanford

Hector Garcia-Monial and myself at Graduation.I am happy to announce that this week I have joined Stanford University as a Consulting Assistant Professor. This may come as a suprise to some people, as I am not exactly your typical academic. Those people would be correct, my job here is not primarily about teaching. The main reason I am joining Stanford is OpenFlow, and it is one of the most exciting technologies I have seen in networking for a long time.

OpenFlow is exciting in two ways. First, it allows you to run new protocols and algorithms on production networks. Before OpenFlow this was very hard, as modern routers have no API that gives access to this low level functionality. Second, it allows you to make centralized yet fine grain routing decisions. This has huge advantages in some areas such as security, data centers or mobility.

Moving on…

Friday last week was officially my last day as an employee at Voltage. The company has been doing great, both in terms of the organization as well as market traction. However after working there for 6 years it felt like it was the right time to move on. Since we founded it in 2002, Voltage has developed from being an early stage technology venture, to a stable, self-sufficient leader in enterprise software. And this means I can move on to do something new.

Early Voltage Team

Building a company is primarily about finding the right people and building the organization. Conversely, the in my count most common cause of death for an early stage start-up is dysfunctional team. At Voltage, we started with a founding team that shared a common vision and terrific investors that were an incredible help whenever we needed them (picture of the early days on the right). On these foundations we together built the great organization that Voltage is today. I am grateful for having had the opportunity to work with everyone in the company, from the executive team, to the board to each and every employee. In retrospect there are only few hires that I would not make again. Going forward I am confident we have the team in place that has what it takes to guide Voltage into the future.

Server Back up Again

As you might have notices, this blog as well as all appenzeller.net email was down for the past few days. The reason was an explosion in The Planet‘s Houston H1 data center, that took out power for our server and about 9,000 other servers as well. More information here. About 700,000 web sites were reported off-line, amongst them b3ta. Assuming the back-up generators hold up, things should be stable for now.

All of this seems to be another good argument for virtualization. While I am not sure how well something like EC2 is set up for an equipment failure like this, at least in theory having multiple data canters and a distributed S3 would allow you to migrate the virtual machines to another center.
