Let us first one opened up cloud computing screen yarn, first of all, according to the relevant hardware and software industry media and revealed the content of view, cloud computing can Qiang be based on simple division of two-level construction and application services. The former, only a very short period of time that must handle large amounts of data while the data of enterprises, such as Google, etc., can be compared need to deploy cloud computing architecture parallel computing; As of today, there are many hardware and software vendors have been active in the business to display their products and services which are provided.
The latter refers to the structure of a service (IaaS), SaaS and Platform as a Service (PaaS) will help enterprises to reduce operating costs such as network applications, such as Amazom's EC2, Google's Google.doc, IBM's "on-demand management services (On Demand Managed Services, ODMS) ", Microsoft (Microsoft) for Dynamics CRM and Salesforce.com, Salesforce, etc.. In some areas, many enterprises began through the network application services for routine operations, such as the Google Doc to replace part of the Office System, etc. However, SaaS companies can really enjoy the pain it?
Transfer costs will be about the level of cloud computing services business will use high and low. Cloud computing services may help companies reduce operating costs of information, such as eliminating the need for maintenance and operation system and data center costs, provided that the companies have resolved the network bandwidth, information security, customization needs and habits change and other staff. "SaaS applications such good intentions, but the key point is still on whether the ease of use," a certain anonymous information officer said so.
"Software and hardware industry on how to divide On Premise business and IaaS, SaaS and other on-demand services, Paas, will cost about the transfer of enterprise level," III, MIC Senior Industry Analyst and Senior Manager of repair in a few days ago, said Jane, Oracle (Oracle) , SAP (SAP) and Microsoft (Microsoft) and so on-demand services are provided in the On Premise and betting companies demand business services, the proportion of differences in the availability of on-demand service and reliability level of demand will be about business use service level will.
In other words, unless the provision of cloud computing, cloud services can help companies reduce suppliers into cloud computing (service) may face the risk, otherwise, want to reduce the operating costs of enterprises, the cloud computing (service) may not be a Posts medicine.
