Nice little article on the appeal of virtual ADCs (Application Delivery Controllers) and a good reminder that advanced load balancing doesn’t only mean powerful hardware appliances.
What’s the appeal of a virtual ADC? A virtualized appliance doesn’t need complicated hardware drivers. It can also run just as fast as the processor underneath, eliminating issues with hardware upgrades or module incompatibility. Some ADC vendors enable virtual ADCs on their physical appliances, which lets customers implement a greater degree of segmentation, such as in multitenant environments. Virtual ADCs can also be deployed on standard x86 servers, which are typically less expensive than purpose-built load balancing hardware.
