There is a distinct difference between managed and unmanaged clouds. While they share several similarities, they differ substantially on a number of core issues:
Unmanaged cloud: An unmanaged cloud provides the core cloud services, but with a “do it yourself” model. In essence, the customer rents access to infrastructure, but they are responsible for maintaining and running all the tools and applications that run on the system.
Managed cloud: In comparison with a managed cloud, a hosting provider will act as an extension of your IT team. Using a managed cloud provider means that you will have a team of expert engineers at your disposal to implement a cloud solution bespoke to your business.
