Scenario 2 - High-Availability VMachine Hosting
Fully Redundant, Load-balanced, Virtual Dedicated Hosting
For websites that require a high degree of availability in addition to the capacity to service thousands of transactions per second this configuration would be ideal.
All components within the solution are redundant with a traditional three tier application design hosted behind a pair of Zeus Load Balancers ensuring load is distributed across the first tier of web servers.
This configuration will greatly reduce planned downtime, which is the greatest source of downtime within any environment, as each component can have maintenance work carried out on it individually without disrupting the other components of the solution. All environments will always require a degree of preventative maintenance.
If the availability of your website is critical to your business, then this solution will ensure that normal maintenance does not have an impact on your business. Unplanned downtime is also catered for within this solution as, should there be a failure on any individual components, there is redundancy to ensure it does not result in a failure of service.
The only type of failure this solution does not cater for is potential site failure, which is very unlikely due to use of Hyper-V spanning the solution across multiple hosts within a secure managed data centre.
