Server Load Balancing

Ensuring online applications to be able to serve customers with minimal downtime is always one of main concerns to IT department. Besides, IT department has to have a thorough plan to enhance the efficiency of network, speed up the response time of online applications, and alleviate the possible server downtime. Scheduled server maintenance also cause certain level of impact, and IT department has to take it into consideration when planning to prevent and mitigate downtime. 

Q-Balancer's Server Load Balancing (SLB) technology is specially designed and aimed at full time operation of application services, optimized response of server farms, load balancing, full-time health check of server, server failure alarm, server failover and fallback, etc.

Q-Balancer's SLB technology is capable of monitoring server health to determine that application servers are not only reachable but alive. It automatically removes downed servers from the server pool and re-distributes traffic among the remaining active servers. The incoming requests to servers will be efficiently distributed, and so as to increase server availability. Q-Balancer's SLB technology comes with four inbuilt algorithms that include Weighted Round Robin, Weighted Least Connection, By Source IP, and By Destination.

Global Server Load Balancing

Disaster recovery is the primary reason that many companies deploy server resources at multiple locations. The role of global server load balancing (GSLB) in this case is to detect the failure at the active site and automatically divert requests to the standby sites. GSLB can be used to enable customers to have better user experience by directing their requests to the closest active sites.

Q-Balancer’s GSLB is a DNS based system that manipulates DNS response based on the availability and performance profile of the data centers. The technology gives you ultimate control in your application delivery service. Ensure that users from certain geographic locations are sent to the right data center. 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 analyze and bring up the other site.

In the diagram illustrated above, a web request is trying to access the website from Europe, and would be served by the server that is located in UK rather than the server in Asia. Q-Balancer’s GSLB is useful for its optimal direction of traffic between sites. Q-Balancer’s GSLB monitors the health of the slave servers in a regular time interval, and directs traffic to those servers for best response. It is also good at disaster recovery with its ability to ensure the continuity across server resources located in multiple geographies
