Public Cloud
Public clouds are owned and operated by third parties; they deliver superior economies of scale to customers, as the infrastructure costs are spread among a mix of users, giving each individual client an attractive low-cost, “Pay-as-you-go” model. All customers share the same infrastructure pool with limited configuration, security protections, and availability variances. These are managed and supported by the cloud provider. One of the advantages of a Public cloud is that they may be larger than an enterprises cloud, thus providing the ability to scale seamlessly, on demand.

Private Cloud
Private clouds are built exclusively for a single enterprise. They aim to address concerns on data security and offer greater control, which is typically lacking in a public cloud. There are two variations to a private cloud:
- On-premise Private Cloud: On-premise private clouds, also known as internal clouds are hosted within one‟s own data center. This model provides a more standardized process and protection, but is limited in aspects of size and scalability. IT departments would also need to incur the capital and operational costs for the physical resources. This is best suited for applications which require complete control and configurability of the infrastructure and security.

- Externally hosted Private Cloud: This type of private cloud is hosted externally with a cloud provider, where the provider facilitates an exclusive cloud environment with full guarantee of privacy. This is best suited for enterprises that don‟t prefer a
public cloud due to sharing of physical resources.

In public cloud, the cloud infrastructure is made available to the general public over the internet and is owned by a cloud provider and in a private cloud, the cloud infrastructure is exclusively operated by a single organization.

Private cloud can be managed by the organization or a third party and may exist on-premise or off-premise.

AWS, Microsoft Azure, IBM’s Blue Cloud and Sun Cloud are the examples of public cloud

AWS and VMware are the examples of private cloud.
  • In public cloud, the services are stored off-site and accessed over
    the internet
    It can be used by general public
    All hardware, software and other supporting infrastructure is owned and managed by the cloud provider
    Example: Amazon Web Service and Microsoft Azure

  • In private cloud, the cloud infrastructure is used exclusively by a
    single organization
    The organization may run its private cloud or outsource it to a hosting company
    The services and infrastructure are maintained on a private network
    Example: AWS, VMware
