Cloud Computing

Cloud Computing

1. Types of Service

   • Processing-this means that that you could run complicating programs remotely
   • Software-You can pay to use the software remotely
   • Infrastructure- you can pay to use the host's hardware
   • Storage- allowing your data to be stored remotely in the host's server

2. Advantages

   • Independence – the user can work with their files on different computers.
   • Cost – the user doesn’t need to buy the latest software as it might be freely accessible through web apps.
   • Backing up - data backed up in the cloud with a reliable provider can be more reliable than storing your information on a hard drive or USB flash memory stick.
   • Services such as storage and software can be accessed on any device that has an internet connection

3. Disadvantages

   • Copyright – the user sometimes loses legal rights to their original material if they store it online.
   • Security - data stored online is vulnerable to security attacks.
   • Storage - it is not always possible to store more than a few gigabytes online with one provider, whereas it is possible to purchase a few terabytes of physical storage to save information at home.
   • Connection – the user can only access their information if they have a network connection.
