What Is Cloud Computing || QuadraNet In The Cloud
InfraCloud, Virtualized Computing, Instant Storage CPU and RAM growth!
QuadraNet is going to be releasing their cloud hosting solution very shortly so we wanted to bring some clarification on exactly what “cloud computing” or “cloud hosting” is. Cloud computing is really how this paradigm should be referenced as it encompasses a relatively diverse field of technology which has several implications but with an underlying baseline infrastructure.
To understand cloud computing it is necessary to wrap your head around a basic concept. The “Cloud” comprises an infrastructure (hardware) aspect which is different than traditional hosting (dedicated server, virtual private server, and shared hosting) and a software aspect that sits on top of the hardware which brings the different components and capabilities of “Cloud” technology together (the on demand availability and scalability of resources and environments to host in). It is really a combination of how the hardware is setup and how the software allows the hardware to function that makes cloud computing new and exciting within the hosting industry.
For those of you who are still fuzzy on what cloud computing is the NIST which is the National Institute of Standards and Technology has provided a solid definition. The NIST is mandated by the Federal Government’s U.S. Department of Commerce branch with developing standards and guidelines including minimum requirements for providing adequate information on subject matter of this type.
As with everything in the technology industry cloud computing is an evolving paradigm. This article will assist in characterizing important aspects of cloud computing. The intention of this article is to serve as a baseline for discussion by offering a means for broad comparisons of cloud services and deployment strategies.
The NIST defines cloud computing as “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. This cloud model is composed of five essential characteristics, three service models, and four deployment models.”
The Essential Characteristics of cloud computing is broken down into five definable characteristics which include: On-demand Self-service, Broad network access, Resource pooling, Rapid elasticity and Measured Service.
Service Models include Software as a Service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service (IaaS).
The most revealing description of cloud computing is summed with amazing precision by the NIST “A cloud infrastructure is the collection of hardware and software that enables the five essential characteristics of cloud computing. The cloud infrastructure can be viewed as containing both a physical layer and an abstraction layer. The physical layer consists of the hardware resources that are necessary to support the cloud services being provided, and typically includes sever, storage and network components. The abstraction layer consists of the software deployed across the physical layer, which manifests the essential cloud characteristics. Conceptually the abstraction layer sits above the physical layer.”
The NIST recognizes four Deployment Models: Private cloud, Community cloud, Public cloud and Hybrid cloud.
- Private cloud. The cloud infrastructure is provisioned for exclusive use by a single organization comprising multiple consumers (e.g., business units). It may be owned, managed, and operated by the organization, a third party, or some combination of them, and it may exist on or off premises.
- Community cloud. The cloud infrastructure is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations). It may be owned, managed, and operated by one or more of the organizations in the community, a third party, or some combination of them, and it may exist on or off premises.
- Public cloud. The cloud infrastructure is provisioned for open use by the general public. It may be owned, managed, and operated by a business, academic, or government organization, or some combination of them. It exists on the premises of the cloud provider.
- Hybrid cloud. The cloud infrastructure is a composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities, but are bound together by standardized or proprietary technology that enables data and application portability (e.g., cloud bursting for load balancing between clouds).
