The difference between private , public and hybrid cloud

There is a clear distinction between these three common cloud deployment methods , as explained by Amazon Web Services ( AWS ).
The cloud computing arm of Amazon defines private cloud as a “ cloud computing environment dedicated to a single organisation .”
• Any cloud infrastructure has underlying compute resources like CPU and storage that you provision on demand through a self-service portal .
• In a private cloud , all resources are isolated and in the control of one organisation . So , the private cloud is also called the internal or corporate cloud . This differs to public cloud , which is a thirdparty cloud service provider that manages the underlying computing resources . AWS explains how it is almost impossible to replicate public cloud infrastructure privately .
• The provider is responsible for resource maintenance and guarantees availability , reliability , and security through service-level agreements .
• You don ’ t buy , own , and maintain physical data centres and servers ; instead , you access technology services on an as-needed basis .
• Tasks , such as runtime resource scaling , are automated for operational efficiency . Private cloud differs from hybrid cloud as the hybrid model extends private cloud computing models into the public cloud . Hybrid cloud seamlessly integrates a company ’ s public and private clouds . With hybrid cloud , clients can store data and run your applications across multiple environments without noticing a difference .
• Hybrid cloud environment consolidates infrastructure , so that users can provision , scale , and centrally manage compute resources .
