The main reason organizations opt to implement an ADC solution is because they provide load balancing, SSL termination, application acceleration, and security, along with seamless access to applications at peak times. ADC solutions are also becoming necessary because, as computing moves to the cloud, they can perform tasks that have been traditionally performed by custom-built hardware.

ADCs also offer added functionality and flexibility for application deployment. Not only that, but they allow organizations to quickly and securely scale up their application services based on demand in the cloud. Modern software ADCs also enable organizations to consolidate network-based services. Critical capabilities for ADCs include SSL/TLS offload, web application firewalls, caching, intrusion detection, compression, and microservices for container applications. With these capabilities, faster delivery times become possible and you also gain greater scalability.

Another reason why it is good to have an ADC solution is because it helps optimize end-user performance and application deployment. ADC solutions assist in application acceleration and provide security for applications. What’s more is they help improve acceleration of business applications by using techniques like application classification, compression, and reverse caching. Another advantage is that ADCs determine security needs as the single point of control for multiple servers. In addition, ADCs handle distributed denial-of-service (DDoS) attacks and secure web applications against common threats using web application firewalls (WAFs), and can also provide SSL offloading and application autoscaling.

If your organization utilizes large-scale content delivery networks (CDNs), it is also important to have an ADC solution in place so you can provide fast web application software services and ensure that high-traffic websites are always on, secure, and available to their users. While ADCs are important and useful for all enterprises, it is even more important for companies that have hundreds of web servers to handle thousands of simultaneous customer requests, which is the case for retail, financial services, ecommerce, and healthcare industries. Load-balancing provided by ADCs ensures their applications can run smoothly even when there are spikes in traffic.

Also important is that ADCs play an important role in network security. In addition to being a first line of defense against DDoS attacks, they can terminate SSL tunneling attacks. To guard DNS servers, some ADCs even offer a DNS application firewall to stop a sudden influx of DNS traffic to a server. Sometimes ADCs also offer data loss protection, where data is inspected to determine whether it meets company policies and is flagged or blocked if it is malicious or a violation of those policies.

Among its other benefits, ADC solutions can be installed as hardware or virtualized software, giving enterprises additional flexibility in how they are deployed. Furthermore, by efficiently managing internal data traffic, they can also support the use of dedicated microservices within enterprise environments. ADCs give your organization an opportunity for improved performance, along with offering many more useful features. Overall, it is easy to see why implementing an ADC solution is important for your organization, especially given all its benefits and advantages, and how it can drastically impact your organization’s success.

What is an application delivery controller (ADC)? An application delivery controller (ADC) is a network component that is primarily used to optimize and manage traffic flow as well as client connections to both web and application servers. ADCs also help with application acceleration and assist with application security. They are typically housed in a data center and their capabilities can be implemented using a hardware or software device. Because they can be installed via hardware or...
