Cloud ComputingIn this report I will look at cloud computing, I will start with an overview of cloud computing. I will then look at the benefits that cloud computing brings. Finally, I will look at people's concerns about cloud computing. What is cloud computing? Cloud computing is computing that involves a larger number of computers connected via a communications network such as the Internet or accessing and storing data over the Internet. instead of your hard drive. There are four main types of private cloud, public, community and hybrid. Private cloud is infrastructure that operates within a single corporate or organizational firewall.

Cloud computing can be accessed from a range of electronic devices capable of connecting to the Internet, such as smartphones and tablets. A cloud computing system can be up and running in a very short time. Adding a new user to the system happens instantly and eliminates waiting periods. In cloud computing, software integration happens automatically, avoiding downtime when using the system. A cloud computing system allows small and medium-sized businesses to access enterprise-class technology that they typically would not have access to due to cost. Cloud computing is generally more efficient. than your traditional IT infrastructure and requires fewer resources to calculate energy savings. With cloud computing, you can save up to 30% less energy consumption and carbon emissions than using on-premises servers..
