NetScaler load balancing

NetScaler load balancing for layer 4 and layer 7 distributes incoming network traffic across multiple servers or resources to prevent bottlenecks and ensure that each resource is being used to its fullest capacity. This results in improved application performance and faster response times.

To ensure that no server or resource fails, NetScaler automatically redirects traffic to a backup server or resource so that services remain available to your application end users. To meet both predictable and unpredictable application demand, NetScaler load balancing automatically scales to handle demand by distributing traffic across additional servers or resources.

By distributing traffic across multiple servers or resources, NetScaler load balancing reduces the risk of a single point of failure or attack, effectively providing an additional layer of security. And it’s cost effective: NetScaler load balancing optimizes resource utilization, so you can make the most of your existing infrastructure and reduce the need to invest in additional hardware or resources.


What you can do with NetScaler load balancing

Use highly advanced health checks, including multi-tier checks, to determine if a server is healthy enough to receive a request

Choose from a wide range of load balancing algorithms to distribute traffic across multiple servers, services, and instances

Process huge traffic throughputs: 32 NetScaler hardware ADCs can be clustered to achieve up to 6.4 Tbps L7 throughput, and software ADCs can be clustered to achieve up to 3.2 Tbps L7 throughput

Use simple-to-configure priority load balancing to assign priorities to your servers or server groups based on their performance, availability, or other metrics

Choose from many persistence options for applications that require session-based or stateful communication

Reduce the number of API calls required to implement two levels of redundancy by at least 40 percent
