Virtual v’s Physical Appliances – 4 Compelling Reasons for Change
The Need for Scalable Architecture
Most organizations today spread their applications across servers based on functional boundaries. Both large and small companies use email servers, file servers, web servers and so on. Over time, the trend has been to dedicate a specific server for each function. This allows for a scalable, highly flexible architecture. As the organization grows, greater demands are placed on the infrastructure. Not just from an increase in the number of users, but also in terms of the geographic footprint. Branch offices will require their own servers for certain applications. Fault tolerance also plays a part, driving larger installations towards multiple, duplicated servers in preference over a single monolithic system.
