Determining the optimum way to configure business computer systems can involve complication determinations of individual business needs, customer demands, and expected traffic. However, one thing that remains constant across business types is the need for redundancy in computer systems. Every aspect of a business’s computer system needs to be redundant, which means that there needs to be backup systems or components built into a business’s computer functions, to protect both data and access in the event of failure.
Routers and Redundancy
Many people overlook routers when they are planning for redundancy. That is because a router failure does not have an impact on data. However, router failures can have a tremendous impact on business, not only preventing employees from accessing information that they may need to perform their job functions, but also preventing customers from accessing a website. Therefore, Cisco developed a hot standby router protocol (HSRP), which ensures that the failure of one router will not lead to failure of the system. However, some things are critical to properly configure hsrp.
The concept behind HSRP is simple. One of several routers is designated as the highest priority in a system and acts as the virtual router for others in the system. That router is assigned the gateway IP address associated with the VIP. Routers are then assigned priority in descending levels, so that there is never a router without priority, even if other routers fail to respond. The result is the default gateway failover. It is critical to ensure that routers in an HSRP setup cannot access physical IPs, but are forced to use the designated virtual IP. Indeni has developed a way to easily check to ensure that routers are accessing the appropriate VIP instead of any physical IPs.
Server Farms and Redundancy
One of the ways to build redundancy into a system to utilize multiple servers, often known as a server farm, to ensure access to the system. This is done with load balancing, a technique that optimizes resources across multiple computers that perform the same functions in a system. How to configure GLB depends on many different factors, including the size of the network, expected traffic, and even expected high-traffic times. The techniques used can be either client-side or server-side.
Constant Access and Direct Marketing
One of the reasons that businesses need to ensure constant access to their systems is to promote their real-time marketing systems. According to RealtimeCampaign.com, this type of direct marketing, which is tailored to what a potential client is interested in buying at that moment, is far more effective than other types of click-thru internet advertisements.
Even though redundancy is an established feature of business computer systems, it can be easy to overlook. All it takes is for a server to be able to access physical IP’s instead of VIPs. Taking the extra step of checking those connections can help ensure later redundancy in the event of failure, ensuring that business can continue without interruptions.
