I was getting really close to switching to another cloud hosting provider due to the lack of private networks. Great to see that Digital Ocean is staying a step ahead.
A cloud is not defined by high availability. Just look at Amazon's cloud - so many single points of failure. Amazon says to distribute your application and redundancy across multiple redundancy zones.
Cloud is defined as:
1. On demand automated provisioning
2. API interface for programatic control
3. Infinite resources from the customer's perspective
4. Virtual addresses for physical location
5. Utility measured service
