As a company grows, there is a requirement
to purchase more physical servers. The cost may range from $400 (fewer than 25
users, low end processor, 1-2GB RAM, 500GB-1TB of RAID storage) to thousands or
tens of thousands of dollars (multiple processors, 16GB RAM). There are certain
disadvantages to this approach:
· Cost
· Need to purchase physical infrastructure
· Pay for services even when not in use
· Scalability- Make adjustments as the company up scales and
downscales
· High cost of maintenance
