1. Cloud computing and cloud storage

   • Availability (B) Data and les may be available anywhere in the world where there is an internet connection.
   • Reliability of the network (C) You need to be able to get through to the host to access and process data.
   • 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.
   • Potentially lower performance (C) The speed of retrieval of data may be slower than it would be on a local database held in-house.
   • 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.
   • Software (C) The host might not be using the latest, fastest and most secure version.
   • Key B = Benefit C = Concern
