We will also briefly cover other redundancy options for servers and other network architecture, power and applications.The Importance of RedundancyToday’s networks are high-tech and most times high speed. Common to most Wide Area Network (WAN) designs is the need for a backup to take over in case of any type of failure to your main link. In this article we will take an in depth view of current technology and strategies used to create redundancy in your WAN and how to properly design, implement, monitor and test in case of any disaster that may occur. Almost every vendor today puts out a line of products to facilitate this need via hardware, software and now via virtualization design. With servers you can cluster and with web properties and applications, you can load balance. Because things break and unforeseen events do take place, we need to evaluate the need for creating an architecture that is ‘highly available’, or up as much as possible, with failures foreseen ahead of time and the only downtime, is to do planned maintenance.To keep the company’s workforces, and their customers connected and operating, we need to plan for it.
