Types of Cloud

Cloud Computing

Cloud computing means hosting services over the Internet at remote location, not at own system. The goal of cloud computing is to provide easy, scalable access to computing resources and IT services. Cloud Computing is a technology that uses the internet and central remote servers to maintain data and applications. It allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing data storage, processing and bandwidth.

Private Vs Public Cloud

A cloud can be private or public. A public cloud sells services to anyone on the Internet. A private cloud is a data center that supplies hosted services to a limited number of people.

Public Cloud

Public Cloud is the cloud computing model where service providers make their computing resources available online for the public. It allows the users to access various important resources on cloud, such as Software, Applications or Stored data. A public cloud is established where several organizations have similar requirements and seek to share infrastructure so as to appliance.

Private Cloud

The Private cloud is resources that are delivered to one platform, which providing high performance, security, and user experience. You can access the desktop, run applications, change settings, and access data exactly as you are sitting in front of the local PC, using its keyboard and mouse.

Virtual Private Cloud

When a service provider uses public cloud resources to create their private cloud, the result is called a virtual private cloud.


Cloud Computing services are broadly divided into three categories:

1- Infrastructure-as-a-Service (IaaS)

2- Platform-as-a-Service (PaaS)

3- Software-as-a-Service (SaaS)


Infrastructure-as-a-Service (IaaS)

Amazon Web Services provides virtual server instance API to start, stop, access and configure their virtual servers and storage. In the enterprise, cloud computing allows a company to pay for only as much capacity as is needed, and bring more online as soon as required. Because this pay-for-what-you-use model resembles the way electricity, fuel and water are consumed.


Platform-as-a-Service (PaaS)

In this the cloud is defined as a set of software and product development tools hosted on the provider’s infrastructure. Developers create applications on the provider’s platform over the Internet. PaaS providers may use APIs, website portals or gateway software installed on the customer’s computer. and GoogleApps are examples of PaaS.


Software-as-a-Service (SaaS)

In SaaS cloud model, the vendor supplies the hardware infrastructure, the software product and interacts with the user through a front-end portal. SaaS is a very broad market. Services can be anything from Web-based email to inventory control and database processing. Because the service provider hosts both the application and the data, the end user is free to use the service from anywhere.
