Now more than ever, today’s businesses require reliable network connectivity and access to corporate resources. Connections to and from business units, vendors and home offices are all becoming equally important to keep the continuity when needed.
Many customers that we talk to have business that runs both day and night and many 7 days a week. This is often the case with retail customers. For them, it is important to realize that to keep a solid business continuity strategy, redundancy technologies should be considered and/or implemented.
Sadly, things break and unforeseen events do happen, 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.
Most customers have run out and have bought two network links – often Internet bandwidth. They usually do into one router. Sometimes two. What we usually see is during an actual ‘event’ or ‘outage’ is that nothing actually fails over. Often, someone needs to manually intervene to make it work.
We have a pretty standard set of operating procedures to make this happen. What is critical in our view is that it needs to work as designed. Our scope documents include the actual fail-over testing which in our case, includes us actually ‘pulling a plug’ on one of the devices to create a fail-over scenario.
