Cloud disaster recovery can sound like an extremally complicated process, but in reality, it is not complicated at all. To explain how does this work you first need to understand what is a cloud and what it is used for.
Cloud storage is essentially a public online storage, that can be used by everyone. It is maintained, managed and backed up remotely. Usually, cloud services have limited free storage for anyone. Depending on the provider you can get up to around 20 GB of free space. If a user wants more space, he needs to pay for that cloud data storage usually monthly rate. Over the years, the per-gigabyte cost is rapidly decreased. Some of the cloud storage providers are adding so-called operating expenses that are making the price little more expensive. One of the biggest concerns that cloud storage users have is the security of their data. Providers know that and they are trying to enhance the security by adding encryption and authentication to their services. There are three major cloud storage models Private, Public and Hybrid.
Private Cloud Storage services provide a devoted environment that is using the firewall protection of the organization. This type of Cloud storage model is best for users that want more control over their data and enhanced security.
Public Cloud is a storage service that offers a multi-tenant environment that is best used for unstructured data. This Data is stored on global servers and it is available in every region or continent.
Hybrid Cloud storage is a combination of private cloud and third-party public cloud service with composition among other platforms for management purposes. This type of cloud storage model is best suitable for business owners, companies, and large organizations. In the past years, more people have started to use the hybrid cloud storage model.
