Many companies, large and small, benefit from using cloud computing today, either directly (e.g., Google or Amazon) or indirectly (e.g., Twitter) rather than traditional on-premise alternatives. There are a number of reasons why cloud computing is so widely used among businesses today.

  • Reduced costs – unlike having on-site hosting, the cost of deploying applications in the cloud can be lower due to lower hardware costs making more efficient use of physical resources.
  • Universal access – cloud computing can allow remotely located employees to access applications and work via the Internet.
  • Software upgrades – a cloud provider will also be able to improve software maintenance by retrofitting previous software versions.
  • Choice of applications – this allows flexibility for cloud users to experiment and choose the best option for their needs. Cloud computing also allows a company to use, access and pay only for what they use, with rapid deployment time.
  • Potential to be greener and more economical – the average amount of energy needed for a computational action carried out in the cloud is much less than the normal amount for an on-site deployment. This is because different organizations can securely share the same physical resources, leading to more efficient use of shared resources.
  • Flexibility – cloud computing allows users to switch applications easily and quickly, using the one that best suits their needs. However, data migration between applications can be a problem.
