Site Load Balancing

FatPipe Site Load Balancing empowers Customers to keep their services available to its customers

FatPipe's Site Load Balancing solution combined with FatPipe's patented SmartDNS technology, provides resiliency and continuity for businesses. It distributes traffic between two sites, utilizing all lines available at each site. Unlike traditional master/backup solutions, FatPipe Site Load Balancing utilizes both sites bandwidth and other resources.

Site Load Balancing

FatPipe Site Load Balancing combines Internet load balancing and patented SmartDNS technology to ensure that their services are always available to their customers. By implementing both line load balancing and Site Load Balancing, the customer has redundancy not only in the event that they have a line failure but also in the event that the headquarter becomes totally off line.

FatPipe's Site Load Balancing empowers customers to improve availability of their applications and have no down time. Even when they experience several line failures, it does not affect connectivity because of the redundant path available due to the use of the FatPipe. FatPipe Site Load Balancing solution does not affect productivity even when they had to bring their headquarter site offline while say - moving to a larger data center. FatPipe Site load balancing enables them to direct the production traffic over to the disaster recovery site.

With the use of the FatPipe Site Load Balancing, customers have been able to grow their business and have been able to offer continued service to their customers.

Site Load Balancing feature provides for distributed availability of critical internet facing Server infrastructure over multiple sites. This feature helps mitigate non-availability of critical infrastructure at a site due to outages caused by various external and internal factors.

Automatic distribution of information between sites ensure that all sites are in sync with each other and only the latest DNS information is provided to client requests.

Site load balancing is an Add-on feature. This feature compliments SmartDNS and enables SmartDNS to spawn over multiple locations. Each location tracks the status of the other location and provides for inbound load balancing between all the locations, or in the event of a failure of a site, redirect all traffic to the sites that are UP and reachable from the internet. This ensures zero downtime for clients and employees who can still access the servers providing business continuity while the Infrastructure team can analyse and bring up the other site.

FatPipe provides Site Load Balancing solution through any of its three products namely, MPVPN/IPVPN /WARP. These FatPipe products, MPVPN/IPVPN/WARP can be configured to provide site load balancing at times when the inbound connectivity to internet accessible servers seems to be very critical. Site Load Balancing also allows for Site Failover between those servers which are located in separate locations geographically that have identical or similar information in both locations. The Main site is known as “Primary” site, and all other alternate sites are referred to as “Backup” sites. Site Load Balancing is made capable of sharing weighted traffic between two sites utilizing all the available lines at each site.

To implement Site Load Balancing, two or more sites are needed to be configured and should be ready to accept incoming requests for the servers that are hosted locally. The MPVPN/IPVPN/WARP at the primary site should be containing all the DNS records in SmartDNS that will be used with Site Load Balancing for all the zones even before they get configured. Once Site Load Balancing is established the SmartDNS on all other sites is configured automatically and from that point on, any DNS change made to one site will definitely be propagated to all other sites. The status of each site is determined by Site Load Balancing dynamically and each line at every site is given priority of either Primary site or Backup site. The IP addresses belonging to Primary lines only will be handed out in DNS requests. For instance if all the primary lines are down, that primary failure will be detected by Site load balancing and will switch the DNS service to the backup lines. This means MPVPN/IPVPN/WARP will release IP addresses for the hosts that belong to the primary lines, and IP addresses for hosts which belong to backup lines or alternate lines will be handed out in DNS requests.

By implementing both site load balancing and line load balancing the customer will have redundancy not only in the event of a line failure but also in the event when the headquarter becomes totally offline. With FatPipe’s site load balancing customers can improve the availability of their applications and have no down time or zero down time. Because of the redundant path availability due to the use of FatPipe the connectivity will not be affected even with several line failures. FatPipe site load balancing solution does not allow the productivity to get affected even when they had to bring their headquarters site offline in case it is moved to a larger data center compared to the present data center as the production traffic is directed over to the disaster recovery site by the help of FatPipe Site Load Balancing.

FatPipe’s Site Load Balancing provides failover between two or more locations and also distributes traffic between sites. FatPipe products are the only products regardless of carriers at each location that can automatically failover one multi-line location to another.

FatPipe provides symmetric deployment as it is provided or placed at both ends of the WAN such as one at the data center and the other at one or more remote locations thus letting FatPipe A and FatPipe B keep constant communication between one another so that the continuity of application flow is not lacking. They check each other’s status as well as share the DNS information following that status. FatPipe A is the Primary site and so all the traffic will be directed to it by default using the IP addresses at that site. If site A goes down then site B will take over authoritative DNS and all the existing traffic that cannot be handled by site A will then be directed to site B and hence the data flow continues without experiencing any down time offering enhanced performance for organizations with remote offices. From this whole process it is evident that the sites are always maintained up and running by using FatPipe’s Site Load Balancing solution.

Advantages of Site Load Balancing:

  • WAN costs are controlled by reducing bandwidth requirements
  • The quality of VPN traffic is enhanced
  • Prevents network congestion while improving bandwidth utilization
  • Optimizes network link utilization
  • The lines are monitored much better
  • Guaranteed minimum quality and bandwidth required
  • Sites are maintained up and running all the time regardless of line failures
