Cloud computing

What is cloud computing? Cloud computing allows us to use computing resources that are located in someone else's data center via the internet. In today's world, the need to have physical servers in an organization is slowly disappearing.

Having physical servers within an organization has the following downsides:

  • An IT team is required to always be available to manage the servers.
  • Servers require physical storage space in a building.
  • They use a lot of power (electricity).
  • They generate a lot of heat because the devices are always powered on.
  • If a hardware failure occurs on a server, this may cause a disruption in network services.

With cloud computing, an organization can eliminate the need for physical servers and simply pay for only the resources it uses from a cloud computing service provider such as Microsoft Azure, Amazon's AWS, or Google's GCP. On the backend of cloud providers, they use a lot of virtualization...
