IT service-centric approach Cloud computing is IT or business service-centric. Consumption-based billing Finally, cloud computing is usage-driven. As infrastructure is off-site typically provided by a third-party and accessed via the Internet, users can connect from anywhere.
In summary, all of these defining characteristics are necessary in producing an enterprise private cloud capable of achieving compelling business value which includes savings on capital equipment and operating costs, reduced support costs, and significantly increased business agility.
Device and location independence enable users to access systems using a web browser regardless of their location or what device they are using e. All of these enable corporations to improve their profit margins and competitiveness in the markets they serve.
Pricing on a utility computing basis is fine-grained with usage-based options and fewer IT skills are required for implementation in-house.
These services need to be easily provisioned and de-provisioned via software automation. There should be levels of redundancy to ensure high levels of availability, but mostly it must be easy to extend as usage growth demands it, without requiring architecture rework.
Cost is claimed to be reduced and in a public cloud delivery model capital expenditure is converted to operational expenditure. Minimally or self-managed platform In order for an IT team or a service provider to efficiently provide a cloud for its constituents, they must leverage a technology platform that is self managed.
A provisioning engine for deploying services and tearing them down recovering resources for high levels of reuse Mechanisms for scheduling and reserving resource capacity Capabilities for configuring, managing, and reporting to ensure resources can be allocated and reallocated to multiple groups of users Tools for controlling access to resources and policies for how resources can be used or operations can be performed All of these capabilities enable business agility while simultaneously enacting critical and necessary administrative control.
Hybrid Share this post: Finally, this infrastructure should be highly utilized, whether provided by an external cloud provider or an internal IT department.
However, the complexity of security is greatly increased when data is distributed over a wider area or greater number of devices and in multi-tenant systems that are being shared by unrelated users. Apply for Cloud Computing Certification Now!!
Today, virtualized environments leverage server virtualization typically from VMware, Microsoft, or Xen as the basis for running services.
Service multiple customers from the same physical resources, by securely separating the resources on logical level. Self-service based usage model Interacting with the cloud requires some level of user self-service.
The following image shows that cloud computing is composed of five essential characteristics, three deployment models, and four service models as shown in the following figure:“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction.”.
The first draft of the cloud computing definition was created in November (see The Ultimate Cloud Computing Definition).
"We went through many versions while vetting it with government and industry before we had a stable one," Mell says. Cloud Computing offers great benefits for organization and individuals by reducing cost and increasing flexibility.
A good and robust Cloud Computing model should consist of all these five essential characteristics. There are also privacy and security concerns. cloud computing and distinguish it from other research areas. The cloud computing has its own conceptional, technical, economic and user experience characteristics.
The service oriented, loose coupling, strong fault tolerant, business model and ease use are main characteristics of cloud computing. 5 essential characteristics of cloud computing by The AT&T Business Editorial Team The discussion about what cloud computing actually means has been going on for a while now, but the thought persists that cloud computing is a form of traditional hosting services.
The National Institute of Standards and Technology (NIST) defines cloud computing as: "Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with .Download
