Cloud Load Balancers

Top–of–the–line server load balancing technology is available at a low cost,
thanks to Z4’s Cloud Server Load Balancing. Get high availability without committing to a long-term contract. We charge for each Cloud Load Balancer instance by the hour, plus concurrent connections. Then we add bandwidth charges starting at $0.14 per outgoing GB. We don't charge for incoming bandwidth.

Cloud Server Load Balancer Options

Cloud Load Balancers enable you to quickly balance the workload of multiple Cloud Servers for optimal traffic management and maximum failover protection. Load balancers distribute workloads across two or more servers, network links, or other resources to maximize throughput, minimize response time, and avoid network overload.

  • Transparent support to load balance any TCP or UDP application
  • Content switching including URL, Cookie, HTTP, and SSL
  • Server Load balancing methods: RR (round robin), least connections, weighted RR and response time
  • Optional global server load balancing functionality
