Computing - Technologies
There are certain technologies that are working behind the cloud computing platforms making cloud computing flexible, reliable,usable.
technologies are listed below.
1) Virtualization
2) Service-Oriented Artchitecture (SOA)
3) Grid Computing
4) Utility Computing

Virtualization is a technique, which allows to share single physical instance of an application or resource among multiple organization or tenants (customers). It does so by assigning a logical name to a physical resource and providing a pointer to that physical resource when demanded.

The Multitenant architecture offers virtual Isolation among the multiple tenants and therefore the organizations can use and customize the application as though they each have its own instance running.
-Oriented Architecture
Service-Oriented Architecture helps to use applications as a service for other applications regardless the type of vendor, product or technology. Therefore, it is possible to exchange of data between applications of different vendors without additional programming or making changes to services.
Computing Service Oriented architecture
Computing
Grid Computing refers to distributed computing in which a group of computers from multiple locations are connected with each other to achieve common objective. These computer resources are heterogeneous and geographically dispersed.
Grid Computing breaks complex task into smaller pleces. These smaller pleces are distributed to CPU that reside within the grid.

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.

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, e,g e-mail.
Cloud
The private Cloud allows systems and services to be accessible within an organization. It offers increased security because of its private nature.
Cloud
The Hybrid Cloud is mixture of public and private cloud. However, the critical activities are performed using private cloud while the non-critical activities are performed using public cloud.
Models
Service Models are the reference models on which the Cloud Computing is based. These can be categorized into three basic service models as listed below.
1) Infrastructure as a Service (IaaS)
2) Platform as a Service (PaaS)
3) Software as a Service (SaaS)
There are many other service models all of which can take the form like XaaS, i.e Anyting as a Service. This can be Netwrok as a Service, Business as a Service, Identity as a Service, Database as a Service or Strategy as a Service.
The Infrastructure as a Service (IaaS) is the most basic level of service. Each of the service models make use of the underlying service model.
# Infrastructure as a Service (IAAS)
IaaS provides access to fundamental resources such as physical machines, virtual machines, virtual storage, etc...
as a Service (PaaS)
PaaS provides the runtime environment for applications, development & deployment tools, etc..
# Software as a Service (SaaS)
SaaS model allows to use software applications as a service to end users.

Computing - Overview
Cloud Computing provides us a means by which we can access the applications as utilities, over the Internet. It allows us to create, configure, and customize applications online.
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 network, i.e on public networks or on private network, i.e WAN, LAN or VPN.
Applications such as e-mail, web conferencing, customer, and accessing the applications online. It offers online data storage. infrastructure and application.
We need not to install a piece of software on our local PC and this is how the cloud computing overcomes platform dependency Issues. Hence, the Cloud Computing is making our business application mobile and collaborative.
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.
1) Deployment Models
2) Service Models

Cloud Model☁️☁️
The Private Cloud allows systems and services to be accessible with in an organization.
The Private Cloud is operated only within a single organization.
It may be managed internally or by third-party.


There are many benefits of deploying cloud as private cloud model. The following diagram shows some of those benefits:
SECURITY AND PRIVACY
Private cloud operations are not available to general public and resources are shared from distinct pool of resources, therefore, ensures high security and privacy.
CONTROL
Private clouds have more control on its resources and hardware than public cloud because it is accessed only within an organization.
AND ENERGY EFFICIENCY
Private cloud resources are not as cost effective as public clouds but they offer more efficiency than public cloud.

Here are the disadvantages of using private cloud model:
AREA
Private cloud is only accessible locally and is very difficult to deploy globally.
PRICING
In order to fulfill demand, purchasing new hardware is very costly.
SCALABILITY
Private cloud can be scaled only within capacity of internal hosted resources.
SKILLS
In order to maintain cloud deployment, organization requires more skilled and expertise.

Cloud Model
Cloud
The Public Cloud allows systems and services to be easily accessible to general public, e.g... Google, Amazon, Microsoft offers cloud services via internet.

There are many benefits of deploying cloud as public cloud model. the following shows some of those
Effective
Since public cloud share same resources with large number of consumer, it has low cost.

Since public cloud employs large number of resources from different locations, if any of the resource fail public cloud can employ another one.

It is also very easy to integrate public cloud with private cloud, hence gives consumers a flexible approach.
Independence
Since , public cloud services are delivered through Internet, therefore ensure location independence.
Style Costing
Public cloud is also based on pay-per-use model and resource are accessible whenever consumer needs it.
Scalability
Cloud resources are made available on demand from a pool of resource, i.e.. they can be scaled up or down according the requirement.

Here are the disadvantages of public cloud model:
SECURITY
In public cloud model, data is hosted off-site and resources are shared publicly, therefore does not ensure higher level of security.
