DevNet Sandbox makes Cisco's free spread of technology available to developers and engineers by providing packaged labs we call Sandboxes. That's right, totally free! There are two types of sandboxes, Always-On and Reservation. Each sandbox typically highlight one Cisco product (think, CallManager, APIC, etc). Sandboxes can be used for development, testing APIs, learning how to configure a product, training, hack-a-thons, and much more!
