Cloud Computing Models and Characteristics

In previous Post we discussed about Cloud Computing and details about Public Cloud and Private cloud on personal or Externally hosted Clouds. Must read the previous post for better understanding Cloud Computing. Here we will discuss Models of Cloud Computing and Cloud Computing Models and Characteristics

So here is Characteristics of Cloud Computing :-

Cloud computing has many type of characteristics, Some of them are:
• Shared Infrastructure — makes use of a virtualized application model, enabling the sharing of physical services, storage, and networking capabilities. The cloud infrastructure, in spite of deployment mannequin, seeks to take advantage of the to be had infrastructure across a number of users.
Dynamic Provisioning — allows for for the provision of services centered on present demand specifications. That is completed automatically utilizing program automation, enabling the enlargement and contraction of service capability, as needed. This dynamic scaling wants to be achieved while preserving high stages of reliability and protection.
Network Access — wishes to be accessed across the web from a large variety of instruments comparable to PCs, laptops, and cellular devices, utilizing requisites-based APIs (for example, ones centered on HTTP). Deployments of services in the cloud comprise
the whole thing from using trade applications to the trendy application on the most recent smartphones.
Managed Metering — uses metering for managing and optimizing the carrier and to provide reporting and billing know-how.On this manner, shoppers are billed for services consistent with how much they have in reality used throughout the billing period.service model cloud computing

Service models 

once a cloud is situated, how its cloud computing offerings are deployed in terms of business units can fluctuate relying on requisites. The essential carrier units being deployed are commonly referred to as:

Software as a provider (SaaS)

customers purchase the capacity to access and use an application or carrier that’s hosted
in the cloud. A benchmark example of that is Salesforce.Com, where critical information for the interaction between the customer and the provider is hosted as a part of the carrier within the cloud.
Also, Microsoft is expanding its involvement in this area, and as part of the cloud computing choice for Microsoft® place of work 2010, its administrative center internet Apps are to be had to office volume licensing buyers and workplace net App subscriptions via its cloud-based on-line offerings.

Platform as a Service (PaaS)

customers buy access to the structures, enabling them to installation their possess application and purposes in the cloud. The running systems and community access aren’t managed through the patron, and there might be constraints as to which purposes can be deployed.
