Cloud computing XaaS: Everything can be served

Recently there is a new word about cloud computing: XaaS. It means anything as a service or modifiable as a service, it depends on who you ask.

Cloud computing has spawned a new term that is a bit of a thrill to think about the explosion of cloud computing, cloud security and cloud architecture.

XaaS is not a specific http://www.aliyun.com/zixun/aggregation/13740.html "> Service model, but it involves a number of other models that complement the public cloud and private cloud industries.

The cloud computing industry has contributed to the evolution of a variety of Web services models, including SaaS, PAAs, and IaaS, which are summed up as SPI models. Other services include storage as a service (storage-as-services), Communications as a service (Exchange-as-services), receptacle as a service (network-as-services), and monitoring as a Service (monitoring is services).

The concept of cloud computing has been out for more than 10 years, even though it has previously been mentioned less. Technical experts have long expected business to acquire and use computing resources from independent suppliers, rather than building and maintaining a data center. The business only needs to pay the cost of IT resources on time, just as with electricity or other facilities.

But no one in the past knew what the cloud was like and how to deliver the service to the user. At that time, the network began to appear and create a sensation, with cheap and sufficient bandwidth to sweep the market. Web browsers provide a platform-based approach to delivering applications, and virtualization gives service providers the necessary power to abstract layers and build multiple-user it facilities. When cloud computing began to take shape, service providers found ways to meet outsourcing needs.

A cloud service model is now subdivided more and more granular-such as identity Management as a service (identity management as services)-so the word anything as a is refined. XaaS is a general description that includes all cloud service providers through the Web. For practical purposes, XaaS is another way of saying public and private cloud services.
