More Example Cloud Services

Advantages of Cloud Computing  Mobility, Flexibility, & Access  Share & Collaborate  Large storage capacity easily available  No software updates  Equipment storage and maintenance expenses outsourced.  Shorter set up times.

Disadvantages of Cloud Computing  Subscription based  Security and Privacy- data ownership  Relies totally on network/internet connection. Doesn’t work with low speed.  Customer Service model is not as established.

Safety  Your password is only as secure as the least protected site that you use.  Don’t use one password for everything! Rule:  Keep 3 copies of any important file (a primary and two backups).  Store on 2 different types of media (such as hard drive, USB, or in the cloud).  1 copy should be stored offsite (and/or at least offline).
