The “cloud” is a term used to describe the delivery of computing resources, such as storage and applications, over the internet. The cloud is made up of many servers located in different parts of the world and are owned and managed by cloud providers, who offer their SaaS solutions to customers on-demand.
When you store data or applications in the cloud, you're not storing it on your company's computers, you're storing it on the cloud provider's computers. This means that your company doesn't need to purchase and maintain its own hardware infrastructure, which can be expensive.
There are three main types of cloud storage:
Public cloud storage: This is the most common type of cloud storage. It's offered by cloud providers such as Amazon Web Services (AWS) and Microsoft Azure and is typically used for storing data that doesn't need to be kept confidential.
Private cloud storage: This type of cloud storage is used by organizations that want to store data in a secure environment where data can only be accessed by authorized users. Private cloud storage is offered by cloud providers such as Rackspace and IBM Bluemix.
Hybrid cloud storage: This type of cloud storage combines public and private clouds. It allows companies to store sensitive data in a private cloud while using the public cloud for less sensitive data.
