    2. Web browsers and mobile apps are easy ways to access cloud
2. Benefits
  1. Cost
    1. You only pay for the storage you use not how much it costs to maintain the hardrives
  2. Availability

3. Drawbacks
  1. Reliability
    1. It depends on how reliable the host of your data is
  2. Software
    1. The company may not be using the latest and fastest versions
  3. Security
    1. No control over the stored files, trust is required
  4. Potential low performance
