Distribute traffic loads so that no single device gets overwhelmed. Quantic Dynamics load balancing solutions allow configurability and flexibility to manage the traffic and resource usage of server nodes in your environment. Local, global, and high availability options can be activated, changed, and deactivated at any time. And if you have questions about which load balancing solution is the best fit for your application, our experts have answers.

Better Uptime

Mitigate traffic spikes by distributing load, and protect your servers from unnecessary downtime.

More Responsive

Balance traffic between available resources so end users do not face traffic jams and slow downs.

Managed

We will manage the load balancer configuration and performance for your specific need.

Options

Local Load Balancing

Local Load Balancing utilizes industry-standard techniques including round-robin, lowest latency, least connections, shortest response, and IP persistence to balance traffic among two or more servers. It can be activated and configured in real-time.

High Availability Dedicated Load Balancers

High Availability Dedicated Load Balancers are available for environments with higher capacity. These load balancers are also available in a high availability option featuring on-demand failover protection and automatic fallback.

Citrix NetScaler® Appliances

Distribute traffic between your servers in one or multiple Quantic Dynamics data centers with Citrix NetScaler VPX. These multifunction network appliances can perform DNS-based local and global load balancing, so you have complete control over how your client traffic will be balanced between your servers.

Global server load balancing is a method to split traffic across multiple servers using DNS and geographical locations as the means to determine to which server traffic will be sent. Generally, a global load balancer will send a client request to a server that is closer to the client, decreasing latency and for the most part improving performance.

The Netscaler is the only customer configurable device that does true global load balancing. Netscaler is a multifunction appliance that can perform DNS based global load balancing lookups. You can delegate via DNS a hostname to resolve to the Netscaler as a DNS server, and the device will look over the servers it is configured to load balance for, perform a distance calculation, and return an A record with the IP of the server closest to the client request.

NetScaler appliances configured for global server load balancing (GSLB) provide for disaster recovery and ensure continuous availability of applications by protecting against points of failure in a wide area network (WAN). GSLB can balance the load across data centers by directing client requests to the closest or best performing data center, or to surviving data centers in case of an outage.

Following are some typical GSLB configurations:

Active-active data center setup. Consists of multiple active data centers. Client requests are load balanced across active data centers.

Active-standby data center setup. Consists of an active and a standby data center. When a failover occurs as a result of a disaster event, the standby data center becomes operational.

Proximity setup. Directs client requests to the data center that is closest in geographical distance or network distance.

To take full advantage of the NetScaler GSLB features, you should use NetScaler appliances for load balancing or content switching at each data center, so that your GSLB configuration can use the proprietary Metric Exchange Protocol (MEP) to exchange site metrics.
