Cloud computing and cloud storage
1. Availability (B) Data and les may be available anywhere in the world where there is an internet connection.
2. Reliability of the network (C) You need to be able to get through to the host to access and process data.
3. Security of data (C) As the les are being stored by the host, you have no control over them. You need to be aware of their security terms and policies.
4. Potentially lower performance (C) The speed of retrieval of data may be slower than it would be on a local database held in-house.
5. cost and convenience (B) You only pay for the storage that you have used. You don’t have to provide and maintain the hardware locally.
6. Software (C) The host might not be using the latest, fastest and most secure version.
7. Key B = Benefit C = Concern
