Seven major business models of cloud computing

"Cloud" is a familiar noun, but when it is combined with "computation", its meaning evolves in generalities and nothingness. Some analysts and vendors define cloud computing narrowly as an upgraded version of Utility computing (Utility Computing): The basic thing is to apply a virtual server to a network range. Other applications are also extensive.


　　


when we take into account the actual needs of it, the concept of cloud computing is becoming clearer: one way to improve the performance and capabilities of idle resources without the need to increase infrastructure input, new hire training or the latest software licensing. Cloud computing encompasses any service model that provides real-time subscription (subscription-based) or Pay-as-you-go (pay-per-use) services over the web, extending the existing capabilities of the IT industry.


　　


cloud computing is still in its infancy, with a large and small assortment of vendors developing different cloud computing services, from mature applications to storage services to spam filtering. Yes, the utility-mode infrastructure vendor is a provider of multiple services, such as SaaS (software as a service), such as Salesforce.com. Today, to a large extent, the IT industry has to accept cloud services individually, but cloud computing developers and integrators have begun to take shape.


　　


based on the views of different vendors, analysts, and it users on cloud computing, we subdivide cloud computing as follows:


　　


1. Software as a service (SaaS) type of cloud computing is the adoption of a multitenant architecture through a Web browser to promote a single application to thousands of users. From the user's point of view, this means that they do not have to invest in the server or software license authorization, from a vendor point of view, compared with the conventional software service model, the cost of maintaining a software application is relatively low. So far Salesforce.com is the most well-known provider of enterprise application software, but software as a service (SaaS) is widely used in human resource management software, as well as ERP software vendors such as workday. Who can predict a sudden leap in software that is a service (SaaS) desktop system from Google and Ohooffice?


　　


2. Utility Computing (Utility computing) This idea is not new, but this type of cloud computing has been revitalized by the presence of AMAZON.COM,SUN,IBM and other virtual machine vendors engaged in storage services and it on-demand access. In the early days, utilities were supplemented by utility calculations and were not applied to mission-critical requirements. But today, utility computing has gradually begun to occupy a place in the data center. Some vendors provide users with solutions to help IT organizations create data centers from commercial servers, such as the 3Tera applogic and cohesive flexible technologies elastic server provide this on-demand service. Liquidcomputing's LIQUIDQ also has a similar service that helps businesses integrate memory, OS, storage and computing capacity into a virtual pool of resources through the network.


　　


3. Cloud Computing Network Services Network services and software as a service (SaaS) is closely related, network service providers to provide APIs to help developers through the network to expand functionality, rather than just provide sophisticated application software. Their range of services ranges from providing decentralized business services (such as strike Iron and Xignite) to a full set of API services involving Google MAPS,ADP Payroll processing, U.S. postal services, Bloomberg and regular credit card processing services.


　　


4. Platform as a service (Platform as a service) platform is a variant of software that serves as a service (SaaS), a form of cloud computing that provides the development environment as a service. You can create your own application to run on the vendor's infrastructure and then pass the network from the vendor's server to the user. That's what Lego (Vegging-out) does. But these services are subject to vendor design and capacity constraints, so users are not free enough. Represents the company including Salesforce.com's force.com and Coghead.


　　


5. Management Service Provider (MSP) management services are one of the oldest forms of cloud computing, and management services are an application that is intended for it vendors rather than end users, such as virus scanning services for e-mail or application software monitoring services. The management security services provided by SECUREWORKS,IBM and Verizon are classified as such, as are the Postini anti-spam services currently being acquired by Google. Other products include desktop system management services, such as center beam and everdream offerings.


　　


6. Service Business Platform Services business platform is a hybrid of software that is service (SaaS) and Management service provider (MSP), which provides a service collector that combines with users. Most commonly used in trade, such as the cost management system allows users to order from the common platform within the user's specifications to the required services and prices in line with the requested tourism products or secretarial services, like an automation service, well-known companies including Rearden Commerce and Ariba.


　　


7. The integration of the network integrated cloud infrastructure service is still in its initial stage. Software service provider Opsource is currently launching Opsource services bus, using cloud integration technologies that have been boomi. Software, the service provider Workday, recently acquired another company in the field, Capeclear, the ESB (Enterprise service Bus) provider, which is primarily engaged in B-to-b business model services. GrandCentral Company is also committed to providing users with integrated solutions, has recently been acquired by Google.


　　


today, the use of cloud computing is not very extensive, the more accurate description of cloud computing may be "sky operations." At the same time, with the gradual popularization of virtualization and SOA in the enterprise, this idea began to be recognized. The extensible infrastructure should eventually be the most cloud-capable node for each enterprise. This is a long-term trend, but it is undeniable that cloud computing will be one of the difficulties in the industry's debate for a long time.
