Understanding App Delivery Controllers in Hybrid Clouds

Many call Application Delivery Controllers (ADC) the next generation of load balancers.  Same as load balancers, they sit in front of web servers. In addition to providing the balancing services, they now help improve scale, availability, fault tolerance, security, and routing. But, not all ADCs are delivered as pure software solutions, designed for cloud-based and virtualized deployments, or work in hybrid cloud environments—items which are becoming mainstream requirements for the Software Defined Datacenter (SDDC) that VMware sees as the future of cloud computing.

Why care about the SDDC?

Industry leaders across the board are gravitating to hybrid clouds for lower costs, no lock-in, greater flexibility, increased speed, built-in disaster recovery, and new capabilities. Of course, there are more reasons, and all these reasons are driving the need to get to a hybrid cloud model. In Sandhill.com’s recent “Leaders in the Cloud” research study from 2010 (and updated in 2011), they said, “our study surveyed more than 500 IT executives and indicated that the biggest growth will be in hybrid clouds (from 13 percent now to 43 percent in three years).”

In order to achieve the promises of hybrid clouds, VMware sees the need for a completely software driven data center so your applications are portable across disparate architectures.  By removing hardware devices, and creating application architectures where all infrastructure is virtualized, delivered as a service, and entirely automated by software, companies can now effectively move apps across clouds to meet their needs.
