Cloud computing technology has become the mantra of many people in recent years. However, we also noticed that in the process of talking about cloud computing technology, in addition to the word "cloud computing", "cloud service" is often mentioned. "What are the differences between the two words in terms of the operation of the business model and the management of the platform?"
What is the difference between cloud computing and cloud services?
Â
When it comes to cloud computing, many people will think of three words - IaaS, PaaS and SaaS. From the literal point of view, S is the abbreviation of Service, which is also the most typical three service modes of cloud computing. Less rigorous is that IaaS is the most basic cloud computing product, and PaaS, SaaS and many other concepts derived from it belong to the category of cloud services. However, from a professional point of view, "cloud computing" refers to a technical architecture, which mainly includes virtualization, automated deployment, distributed computing and other technologies. The advantage of this technical architecture is that it can perform very good parallel computing performance. , scale scalability and robustness.
Â
The “cloud service†refers to the on-demand and measurable IT service provided by the cloud technology architecture. It can be used to replace the user-built IT service. It is mainly divided into three levels: IaaS, PaaS. , SaaS.
Â
Why is the concept confused?
The reason why these two concepts cause confusion in the country is probably caused by three reasons: First, the people make up the momentum. Whether it is an early cloud computing vendor or a customer, or even a vendor providing cloud storage services to users, there is a suspicion of advocating the concept of "cloud computing." From the current point of view, this strategy can not be said to be unsuccessful. The consensus of the cloud computing market space has been formed. The government has also expressed its support for the development of cloud computing. The most important thing is that under the concept of cloud computing, some basic clouds Services have long penetrated into every corner of the Internet, such as cloud storage services. Second, the customer is supreme. The cloud computing giants, including Ali and Tencent, have been emphasizing the value of “computation†in the past because the competitors at the beginning of cloud computing are traditional IDC service providers. The external understanding of cloud computing is also narrow, usually The network gets the resources it needs in an on-demand, scalable way. It is easy to understand that it is easier to win the favor of customers by emphasizing the flexible service of cloud computing when the service is not dominant. Third, the difference is wrong. In addition to the popular cloud storage service, until today, many cloud service buyers are still enterprise users, especially large enterprise users.
Â
At the same time, for many of the early users who pay for cloud computing services, their early demand for cloud computing is limited to the IT infrastructure, the most typical is Amazon's EC2, the way to provide Web services allows users to flexibly in virtual Run the program on the host. However, EC2 translation should be an elastic computing cloud. The term “cloud computing†was adopted directly in China, and it was later used to summarize various cloud computing services.
Will cloud services have more value than cloud computing?
Â
There used to be such a voice in the industry that cloud services will gradually abandon technical architectures such as cloud computing in the future, and will have greater value than traditional cloud computing architectures. But from the user's point of view, in addition to the analysis of cloud computing service architecture and service model, we also need to test and apply the overall cloud platform testing, BUG analysis, data analysis tools, promotion platform and other services. filter. Just like we usually describe cloud computing as the water, electricity, coal, and basic resources of the Internet, most users don't care how these basic resources come from, but what they can do. From this perspective, cloud services are more popular than cloud computing, and they mean a bigger market.
Â
So in a word, cloud services are actually running on top of cloud computing. As the technology infrastructure of the entire cloud platform, cloud computing plays a very important role in promoting the rapid development of the entire cloud computing business. The form compensates for the lack of infrastructure, and entrepreneurs can break the barrier to entry into the cloud computing industry by leasing public or private clouds.
Â
The hot word cloud computing has taken root in many industries in recent years. Therefore, for the future development and trend of the cloud computing industry, it is very necessary to abandon it. For users, some specific implementations of cloud services are inseparable from the underlying support of cloud computing technology and cloud computing architecture, because for users, the changes brought by cloud computing are bound to pass daily work, life and so on. More "grounding gas" to experience.
