It is a murky boundary which separates the dynamic website from the cloud app since there are many similarities. Like the question, "Is a SUV a car or a truck?". The meaning is in the mind of the beholder. Some of the obvious cloud apps are used for data backup and include encryption and compression. Cloud apps provide easy access for multiple users in a mobile business society.
