In this model, the applications are hosted by a vendor or a service provider.

It supports Web services.

It has local accessibility only.

SaaS is related to 'on demand' computing software delivery models.

It is based on multiple data products.

The public and private should be less coupled.

By applying Cloud homogeneity for the application

By Clouds enable automated security management

By Redundancy/Disaster Recovery.

Data storation.

Measured services provide such controlling features. Resource pooling has a pool of such resources that need to be assigned.

It provides transparency for both the provider and consumer of the utilised service.

In this service, a consumer can unilaterally provision computing capabilities, such as server time and network storage.

In this service, the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model.

In this service, the providers and consumers have shared resources.

This service is responsible for the resources to be configured elastically on the basis of demand.

In this service, the capabilities are available for provisioning often appear unlimited and can be appropriated in any quantity at any time.

In this service, the cloud systems automatically control and optimise resource use by leveraging a metering capability at some level of abstraction, appropriate to the type of service.

In this service, the resources are optimised.

This is a pre-planned service.

It facilitates the deployment of applications or services without the cost and complexity of buying and managing the underlying hardware and software.

In these services, the users are provided access to application software and databases.

It provides physical virtual machines and other resources.

IaaS-cloud providers supply the resources on-demand from their large pools installed in data centers.

IaaS-cloud providers provides resource optimisation.

To protect data from being compromised.

It helps to protect data from any unauthorised access.

It provides data availability.

It does not prevent from data loss.

It provides security for both providers and the customers.

It is a model for enabling convenient, on-demand network access to a shared pool of configurable computing resources.

In this computing, the clouds manage the infrastructures in a centralised platform.

These fundamentals are necessary only for public cloud infrastructure.

It provides optimisation of clouds.

It manages the clouds in the public place based on their availability.

It provides the services specific functionality for each level in the application.

It acts as an interface for the service provider and consumer.

The consumer is responsible for the advance level security.

It provides a resource management security.

It provides resource optimisation.

Agility improves with users' ability to re-provision technological infrastructure resources in cloud computing.

Easier Maintenance of applications

Virtualisation

SQL injection.

It refers broadly to any distributed application that distinguishes between service providers (servers) and service requestors (clients).

It is a distributed architecture without the need for central coordination.

It refers the packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility.

This computing has several computers that are used mainly by large organisations for critical applications.

It manages the public clouds based on their availability.

It provides the allocation of the resources on pay-per-use basis to the customers.

The customers contract in advance a predetermined amount of resources, which are prepared in advance of service.

In this, the customers purchase cloud services directly from the provider, typically through a web form or console interface.

The customer pays on a per-transaction basis.

It provides optimised resources.

In this virtualisation, the guest operating system requires modification.

In this virtualisation, the hardware is not simulated.

In this, Virtual Machines provide an environment that is logically separated from the underlying hardware.

In this virtualisation, the process is rapid.

This virtualisation has some external resources.

It forwards the request to the broker.

It requests the data from cloud storage system.

It returns the data to the broker.

It sends the data to the server.

It checks the authenticity of the system.

The data stored in cloud can be accessed from anywhere.

It provides a systematic approach for the protection of data.

Brokered Cloud Storage Access is one of the approaches for isolating storage in cloud.

A proxy with no access to storage, but access to both client and broker

It works on optimisation of shared resources.

It provides the allocation of the resources on pay-per-use basis to the customers.

The customers contract in advance a predetermined amount of resources, which are prepared in advance of service.

In this, the customers purchase cloud services directly from the provider, typically through a web form or console interface.

The customer does not pay on a per-transaction basis.

It works on data storage.

It determines the inaccessibility of such storage.

It offers online storage space on demand.

This cloud storage system presents what appears to the user to be a raw disk that the user can partition and format.

This storage is suitable for many systems.

It provides resource pooling.
