![Public vs. Enterprise Cloud
– Is it a Fair Fight?
Comparison of very large service with mid-size: (~1000 servers):
Large Service [$13/Mb/s/mth]: $0.04/GB
Medium [$95/Mb/s/mth]: $0.30/GB (7.1x)
Large Service: $4.6/GB/year (2x in 2 Datacenters)
Medium: $26.00/GB/year* (5.7x)
Large Service: Over 1,000 servers/admin
Enterprise: ~140 servers/admin (7.1x)
• Large block h/w purchases significantly more economic
– Large weekly purchases offer significant savings
– H/W Mmanufacturers willing & able to do custom designs at scale
• Automation & custom s/w investments amortize well at scale
• Summary: scale economics strongly in play](https://image.slidesharecdn.com/cloudcomputing-jan2011-chandna-110304235240-phpapp02/85/Cloud-Computing-Jan-2011-Chandna-15-320.jpg)
