Why not Public Cloud yet?
Why not public cloud yet?
Standards and Interoperability:
•There are not standards or interoperability between different public clouds. The security around cloud computing and cloud storage is not matured yet and none of the cloud providers share their infrastructure information if any of your clients ask for due diligence information.
Cost on your existing infrastructure:
Public cloud may be a good option for Development and QA environments however, consider your existing investment on infrastructure as the current cost of running those physical servers may be cheaper than running them in cloud considering their setup costs, OS and application licensing fees. Eventually when you retire our servers, based on their role, you could move them to cloud.
Network Bandwidth:
Traditionally the network is designed to handle local traffic (20% internet; 80% intranet). Moving applications to cloud would change this to (80% internet, 20% intranet) which will result in higher bandwidth costs with your ISP
Contracts with existing Colo data centers:
If you have contracts with data centers that goes for many years you may want to stick to physical servers( and move to Private Clouds) as the cost of terminating existing contracts may overcome the benefits of moving to cloud.
