on
your
business
strategy.
Currently, there are three main cloud models, public, private and hybrid.
Public Cloud The public cloud is the most basic and simple implementation of the cloud, where cloud service providers provide customers with various types of resources, such as applications (SaaS), infrastructure (IaaS), or the entire platform (PaaS). This typically applies to the pay-per-use model where the customer pays the service provider for the cost of the service used. Microsoft Azure and AWS are the two most common examples of public clouds.
Private Cloud Managed private cloud are similar to on-premises and have the advantage of a cloud-based model. This type of clouds are built-in on the company's infrastructure, but can quickly increase and decrease capacity and install virtual machines to make the best use of available resources. VMWare is a common private cloud service support.
Hybrid Cloud Hybrid clouds enable customers to enjoy the benefits of public and private clouds. The IT environment of most organizations is too complex to adopt a fully public or private cloud-based approach. Budget constraints may also prevent companies from implementing private cloud models because data security issues and security requirements may prevent them from adopting a fully public model. In this case, the hybrid model allows the creation of public and private clouds to meet both of these requirements.
