Application development, deployment, delivery and consumption are undergoing a radical transformation. Unfortunately, the Application Delivery Controller (ADC) providing load balancing, content switching, rewrite, optimization and application security has not evolved to keep up with this transformation. The Avi Networks solution is purpose-built for the cloud and mobile era using a unique analytics-driven and software-defined architecture called HYDRA™ (Hyperscale Distributed Resources Architecture). This white paper describes the Avi Networks HYDRA architecture in detail.
