In the beginning, we had load balancers. They sat in front of web servers to offload effort from those servers, bringing benefits such as more efficient resource utilization, quicker response times, and highly available applications. Then, load balancers became Layer 7-enabled. This opened the door for traffic manipulation, acceleration of HTTP, ipv4 to ipv6 gateways, and negative security. With so much under their control, load balancers evolved into true Application Delivery Controllers, or ADCs. And that was a great thing … at first.
You Can’t Get There from Here
ADCs were so effective that it seemed like every business owner wanted one. Sometimes, security requirements related to a specific location or a concern about risk caused the need for a separate ADC to be established. Other times, people wanted a particular placement in the network or the cloud, which meant they had to have their own ADC as well.
But ADCs didn’t talk to one another. Each ADC was essentially isolated in its own individual neighborhood, puttering along on a few local roads. With multiple ADCs in place – sometimes dozens or hundreds – businesses found themselves coping not just with a few isolated ADCs, but with a sprawl of ADCs scattered across the IT landscape … all cut off from one another and all acting independently.
ADC sprawl is ugly, since ADCs are expensive and complex to maintain. When you realize that the vast majority of users don’t need the size of the ADC they have, the cost and effort is even more frustrating. It just doesn’t make good business sense.
ADCs on the Autobahn
But what if you could get on an ADC highway system that links all those individual neighborhoods? Is traffic heavy on one road? Divert cars to an alternative route. It’s that simple.
Think of the possibilities for easy access, reporting, and control. Think of what you could do in a connected ADC environment where you can allocate test, dev, and UAT ADC functions at no extra license cost. Think about the benefits you could reap when you right-size your ADC service and features based on what makes sense for each application. Think of the cost savings. Think of the business agility.
But don’t just think about it: experience it. This isn’t a “what if” scenario. It is a “what is” scenario with Pulse Virtual ADC (vADC) solutions. It’s time to leave the local roads behind, and accelerate your business on the Pulse vADC highway.
