Best of Both Worlds: How Virtualization will Impact the ADC Market

It’s easy to spot trends after they’ve already caught fire, but identifying them in their beginning stages is much more difficult. Virtualization is a business trend that has been gaining steam for quite a few years, and with benefits including greater efficiency and cost savings, it has already become a major staple for companies all over the world. Similarly, the application delivery controller (ADC) market has turned into an important aspect in the business world, as companies use ADCs as a kind of advanced load balancer for company servers. With both trends taking on important roles, it should probably come as no surprise that the two would be combined at some point. The trend of virtualized ADCs has only just begun, and those businesses wanting to become early adopters will quickly see how beneficial this “best of both worlds” approach is.

Though not as well-known as virtualization , application delivery controllers provide a number of important benefits to businesses. ADCs essentially enhance application performance in a number of ways, mostly by utilizing resources at an optimal rate, reducing response times, and avoiding server overload. In addition to those benefits, ADCs also provide an extra layer of protective security, particularly as a way to detect and fight denial-of-service attacks by blocking suspicious or undesirable requests while still performing maintenance on all critical applications. While these benefits certainly helped businesses, maintaining ADCs quickly grew into a complicated endeavor. With this challenge, companies took to using virtualization to address the complex ADC environment, and the beginnings of a trend were born.

Virtualized ADCs show a lot of promise, but it’s still too early to see just how much impact they’ll actually have. Experts have predicted virtualized ADC revenues will exceed $200 million in 2014, but the real explosion won’t happen until the following year. The act of virtualizing ADCs is similar to that of virtualizing servers or desktops, mainly by consolidating multiple ADC devices into a single device. The result of virtualized ADC basically combines many of the benefits of server virtualization with those found with ADCs in general. Virtualization already has the ability to maximize application infrastructure, providing for reduced costs and greater security. This factor can be extended to ADCs, making them much easier to manage by combining multiple devices and allowing them to be controlled from one interface.

Easier management may be enough reason to adopt virtualized ADCs by itself, but it also leads to faster deployment of new application services. This is partly because ADCs have become software products, leading to much more flexibility when it comes to supporting applications. There’s also a complementary element to using ADCs and virtualization. The two work together to provide a higher server consolidation ratio, which not only leads to the easier management discussed above but some major reductions to cost. By consolidating multiple machines into one, companies can save on hardware costs and overall operational expenses. There are also environmental benefits to take into consideration. By reducing the number of physical machines needed, cooling expenses and energy costs can be greatly reduced while also positively impacting the environment. These savings are even available to small businesses, who often have very tight IT budgets, so for many the upfront cost of virtualization and ADCs can be recouped over time.

Virtualization, in conjunction with ADCs, can make a big difference for businesses, whether large or small. If you feel that you need more info about virtualization there are virtualization training courses online . With the two used together, companies will be able to respond to challenges a lot more quickly, meet ever-shifting demands with greater ease, and save money in the long run. We’re still in the midst of the start of the virtualized ADC trend, but that may be even a better reason to start now and be one of those businesses receiving the valuable benefits from an early date. As companies continue to expand and rely more on technology, it will become apparent that ignoring ADCs and virtualization will no longer be an option.
