Ensuring Connectivity for the Incoming Requests to Internal Servers

>  Inbound Load Balancing & Failover
Each host connected to the Internet has a unique IP address, with which other devices can find it. Users access online information through domain names, like google.com or yahoo.com. The Domain Name Systems (DNS) is like the phonebook of the Internet. DNS translates domain names to IP addresses, while web browsers interact through IP addresses; therefore, browsers can load the Internet resources.

When a DNS request is received by a DNS server, the DNS server then returns with the IP address of the domain requested initially. This might involve single point of failure, where the external request might not be able to access the server if the WAN link goes down. Simultaneously using multiple IP address provided by the ISP connections can possibly be a better way to sort out the issue with single point of failure. The hosted services appear as different IP addresses to the external DNS requests. However, DNS does not check for WAN outages or status, and so it might return the request with an IP address of the faulty or congested WAN links.

The Q-Balancer Inbound Load Balancing has the ability to control the access to corporate-hosted servers according to the link status. The incoming requests will be distributed across all available uplinks, and be prevented from accessing corporate-hosted servers via the faulty or congested WAN links. Given this ability, content delivery to the incoming requests will be accelerated, and bandwidth utilization for uplinks will be increased.

The Q-Balancer Inbound Load Balancing is the best-in-class solutions used by heavy-traffic enterprises to deliver their content to their customers quickly, reliably, and securely.
