Single cloud computing is when an organization uses only one cloud service to operate data transfers and the like. These single cloud services can include private, public, or on-site servers. It is also important to note that there are no other integrations, as there were with hybrid cloud servers. If any errors or issues are to take place, they will only be taking place in one area, so it will be easy to detect if/when something goes wrong.
In private cloud servers, everything is up to the organization or individual using the program. Everything is contained in-house, including the applications and data that one may be using or creating. Security measures are also your own to make, and the location for your IT Department is likely on-site, or even yourself. There are many more stressors when dealing with private servers, including security measures, but also, storage and space, monthly/yearly costs, and overall ease of use, but as stated previously, each of these issues is lessened by the fact that as the issues occur, less time will be spent trying to locate issues, and more time can be spent working toward getting systems operational again. Private cloud computing is simply the computing necessary for your organization and nothing more.
Public cloud computing is just computing that’s delivered via the internet and shared between many different organizations. The benefits of public cloud computing start with lower costs. On public cloud servers, there is no need to purchase hardware or software (aside from the devices owned and operated by you at your location. You also will only need to pay for any services you use, with no other hidden fees or fees you may not know you were paying for. After extended use, you may notice that there is no necessary maintenance on your part. The service provider will provide upkeep and maintenance. Another great benefit of public cloud computing is the very near-unlimited scalability. The resources that are available to meet your business needs, are not only available fully to you, but they are also much easier to use and come at no extra cost for use in a cloud service.
