Data systems resembling the Cloud were developed by computer scientist J. C. R. Licklider with the Advanced Research Projects Agency Network, (ARPANET),
that allowed people to share data between computers. Cloud usage increases in the 1990s with Salesforce operating their software-as-a-service (SaaS) on Internet Cloud storage.
SaaS being a licensed storage system from a service provider on a subscription. The 2000s saw many major tech companies switching over a large portion of their data storage to the Cloud:
Google creating Drive
Amazon with Amazon Web Services
And in 2011 Apple released the iCloud
A multitude of independent tech startups were founded centered around Cloud storage, (Maayan, 2021).
One prerequisite for operating a Cloud server is access to the internet, because the Cloud operates on a virtual server. These servers can come in many forms,
depending on how centralized and private an organization desires: Public Clouds are ones provided by an external provider and can be accessible by many individuals and organizations,
Private Clouds are ones specifically provided by and for a single organization, while Hybrid Clouds still require on-premises servers but still having internet access to storage, (Rhoton, 2009).
