Advantages of Private Cloud

 Disadvantages of Public Cloud

• Do not have full control over DNS
• Cannot have different DEV, TEST, PRE-PROD environments
• Do not have access to full debugging and APIs
• No local data transfer rates (i.e. Ethernet 1TBs-1, USB3 10GBs-1 )
• Lose control of Backups
• ...

You still need a Private Cloud!

Private Cloud hosted in Public Cloud can assist in transition from Public Cloud to Private Cloud
But that’s about it!

Anyway:

• Companies exceeding certain turnover & revenue (size) can run their own infrastructure
• Litmus Test: Internet Connections for an SME … also include Ping Test & Network Latency

After a certain point it becomes cost-effective to own your own hardware!

• Azure VPS, CloudShare can be very expensive
• Does  not necessarily make sense to rent given how cheap computers continually become!
