In the past, application delivery controllers weren’t deployed widely. But in today’s increasingly digital world, these ADCs are becoming much more prevalent – and even necessary – as NetOps struggle to keep up with the applications they support. Whether they are in retail, financial services, healthcare or a number of other dominant industries, businesses have hundreds of web servers sitting behind their applications to handle multiple customer requests simultaneously. An Application Delivery Controller (ADC) is positioned between the end-customer and your servers to manage this traffic, making it a key component of the network as it delivers the business-critical web application to your end-customers.
Over the past decade, application delivery networking has drastically evolved. Perhaps most notably, load balancing has completely transformed into the advanced Application Delivery Controller (ADC) market we know today. The impact of digitalization on the ADC market has opened doors for platform services, cloud-native ADC solutions and open-source load balancing software services.
Gartner study reports, “In the early 2000s, server-based load balancers evolved into complex, multifunction custom appliances from companies like F5 and Citrix NetScaler. Application-centric personnel are driving a return to lightweight, disaggregated load balancers, creating challenges and opportunities for I&O leaders.”* However, according to industry experts, this transformation presents both benefits and new challenges.
Business units facing new levels of demand can no longer wait on the traditional change management process, and instead opt for ADC services that are faster to deploy. But, for critical applications that call for more stability, they choose to deploy in traditional environments to ensure availability and security. This results in growing heterogeneity in enterprise IT. As deployment trends change and the needs of enterprises shift, organizations are considering a combination of both new and legacy services to build more agile infrastructures. From a management standpoint, this approach presents both new advantages and new hurdles.
Recent advancements in technological present a need for NetOps and DevOps teams to adopt a simple ADC deployment model to manage the application delivery platforms of the future.
