Cloud Computing Course
What is Cloud? The term Cloud refers to a Network or Internet. In other words, we can say that Cloud is something, which is present at remote location. Cloud can provide services over public and private networks, i.e., WAN, LAN or VPN. Applications such as e-mail, web conferencing, customer relationship management (CRM) execute on cloud.
What is Cloud Computing?
Clouds may be limited to a single organization (enterprise clouds), or be available to multiple organizations (public cloud). Cloud computing offers platform independency, as the software is not required to be installed locally on the PC. Hence, the Cloud Computing is making our business applications mobile and collaborative.
Basic Concepts ?
There are certain services and models working behind the scene making the cloud computing feasible and accessible to end users. Following are the working models for cloud computing:
Deployment Models
Service Models

Deployment Models
Deployment models define the type of access to the cloud, i.e., how the cloud is located? Cloud can have any of the four types of access: Public, Private, Hybrid, and Community.
Public Cloud
The public cloud allows systems and services to be easily accessible to the general public. Public cloud may be less secure because of its openness.
Private Cloud
The private cloud allows systems and services to be accessible within an organization. It is more secured because of its private nature.
Community Cloud
The community cloud allows systems and services to be accessible by a group of organizations.
Hybrid Cloud
The hybrid cloud is a mixture of public and private cloud, in which the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
Public Cloud
The public cloud allows systems and services to be easily accessible to the general public. Public cloud may be less secure because of its openness.
Private Cloud
The private cloud allows systems and services to be accessible within an organization. It is more secured because of its private nature.
Community Cloud
The community cloud allows systems and services to be accessible by a group of organizations.
Hybrid Cloud
The hybrid cloud is a mixture of public and private cloud, in which the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
Service Models
Cloud computing is based on service models. These are categorized into three basic service models which are -
Infrastructure-as-a-Service (IaaS)
Platform-as-a-Service (PaaS)
Software-as-a-Service (SaaS)
Infrastructure-as-a-Service (IaaS)
Platform-as-a-Service (PaaS)
Software-as-a-Service (SaaS)
Benefits
Cloud Computing has numerous advantages. Some of them are listed below -
One can access applications as utilities, over the Internet.
One can manipulate and configure the applications online at any time.
It does not require to install a software to access or manipulate cloud application.
Cloud Computing offers online development and deployment tools, programming runtime environment through PaaS model.
Cloud resources are available over the network in a manner that provide platform independent access to any type of clients.
Cloud Computing offers on-demand self-service. The resources can be used without interaction with cloud service provider.
Cloud Computing is highly cost effective because it operates at high efficiency with optimum utilization. It just requires an Internet connection
Cloud Computing offers load balancing that makes it more reliable.
