For the uninitiated, Tech Field Day is an event hosted by Cisco where delegates come and listen to a technical deep dive by a Cisco expert in a presentation and discussion format. These delegates range from bloggers, speakers, freelance writers, and podcasters that have a public presence that has an immense influence on ways that products and companies are perceived by IT practitioners. There are a few different branches of Tech Field Day: Networking Field Day, Wireless Field Day, Virtualization Field Day, and Storage Field Day.
