What are Application Delivery Controllers (ADC)?

Application Delivery Controllers (ADCs) are software solutions designed to optimize the performance, security, and availability of applications delivered over the internet. They manage traffic between users and applications by distributing it across multiple servers, ensuring load balancing and preventing overloads. ADCs also provide security features like SSL offloading, DDoS protection, and web application firewalls to safeguard applications from attacks. By improving application response times and ensuring high availability, ADCs enhance user experience and help maintain service continuity. They are commonly used in data centers and cloud environments to ensure efficient and secure application delivery.

    IBM Load Balancer
    As strain increases on a website or business application, eventually, a single server cannot support the full workload. To meet demand, organizations spread the workload over multiple servers called "load balancing", this practice prevents a single server from becoming overworked, which could cause it to slow down, drop requests, and even crash. Load balancing lets you evenly distribute network traffic to prevent failure caused by overloading a particular resource. This strategy improves the performance and availability of applications, websites, databases, and other computing resources. It also helps process user requests quickly and accurately. From a user perspective, load balancing acts as an invisible facilitator that sits between a client and a group of servers, ensuring connection requests don’t get lost. Without load balancing, applications, websites, databases, and online services would likely fail when demand gets too high.

    FortiADC

    FortiADC

    Fortinet

    FortiGSLB quickly and securely delivers. Applications anywhere. Horizontal scalability is a key factor when it comes to designing and deploying internet-based services and solutions for enterprise and carrier networks. These organizations must be able to quickly and easily add new network resources and deploy cloud-based applications to ensure business continuity as well as smooth disaster recovery in the event of data center or server failure. Yet, if internet connectivity or security is unreliable, these efforts are often stalled. Without this flexibility, business demands often force enterprises to upgrade to bigger and more powerful hardware devices to manage these capacity challenges. These upgrades can be costly and add significantly to the total cost of ownership (TCO) without addressing the issues of failover and service availability.
