FanSaaStic.com makes every effort to balance the price you pay against the security and availability of the service. This is a never ending struggle for every service provider and thier customers on the planet. The ongoing choice between being secure and always running and paying less for it. Upgrading to Enterprise simply means that your account is supported by two datacenters in or near your Region and not a single one. If in the unlikely event your primary datacenter goes down and you are Enterprise, FanSaaStic.com automatically points to the secondary datacenter and continues to work. The FanSaaStic.com Enterprise Service doubles your base subscription prices as well as all monthly and capacity serivces because it doubles the infrastructure you use to increase security and availability and decrease the odds of you, your company and your users experiencing unplanned down time. Now the odds of the datacenters we use going down without the Enterprise Subscription is still very unlikely. That being said, it happens and when it does, it costs customers sometimes millions of dollars because they chose to save money up front. It's a business decision that they may be able to live with and that is fine so FanSaaStic.com provides a non-enterprise service for less cost. But you as the owner of the service needs to choose between eliminating what are called 'single points of failure' and allowing potential downtime that may or may not occur and if it does, can you afford the downtime. The difference between 99.999% updtime and 99.99% (called three-9's vs. two-9's in the business) is only 5.25 minutes a year! It's important to note that when it does happen, our cloud service providers in most cases brings the down data center back online as soon as possible. So if you can afford another nine's downtime, then don't subscribe to Enterprise. If not, use it and feel assured that a datacenter going down will not cost your users and your business expensive downtime. FanSaaStic.com syncs your data between the two datacenters and when complete, re-points your account back to the primary datacenter. Be advised that some datacenters secondary datacenter may be overseas from your primary so if downtime occurs, you may experience slower application response times but you will remain up which is the goal. Of course, as always, it's your call.
