The emergence of software-defined application delivery technology – and what it can do for your network

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

The flexibility of the cloud has driven IT to look closely at opportunities to replicate that agility in their own infrastructure and operations. Automation initiatives have optimized many layers of the computing stack, but application delivery services remain a last-mile problem as network teams find themselves hamstrung by inflexible legacy architectures.

While virtual appliances for load balancing, long thought of as the answer for software-driven infrastructure, have existed since the advent of virtualization, they inherit most of the architectural challenges of legacy solutions, including limited scalability, lack of central management and orchestration, and performance limitations. Instead, what is needed is an application delivery architecture based on software-defined principles that logically separates the control plane from the data plane delivering the application services.
