Cloud computing is a service, and cloud computing platform is a service.. Let's take a look at the cloud computing platform categories, such as IaaS, PaaS, and SaaS. The last S represents the Service. When we use a cloud computing platform, we purchase services. By understanding this, we understand the core of cloud computing and solve many selection problems. For example, we use a cloud computing platform or purchase hardware for maintena

No matter how big a company is, it is promoting its own basic platform, developing applications on the platform, and providing a convenient shop for purchasing services through SAAS, this not only facilitates the use of good application services,
It also provides business opportunities for developers, so the current C/S architecture model
Editor's note: This list is shared by Andy, a foreign programmer. It includes the "Platform as a service platform as a service" product built in various languages. Not all services are useful to everyone.
Note: PAAs (platform-as-a-service) is a platform-as-a-service. PAAs actually refers to submitting a software development platform to users in Saas mode as a service. Therefore, Paas is also an application of the

more times. But we didn't dwell on how many times it was. So it will be as "greedy" as possible to give us matching characters, in this case it matches to the last ".".
How do we solve this problem? Just add one after "+"? "Just fine."
Import re
key = r "chuxiuhong@hit.edu.cn"
p1 = r "@.+?\." #我想匹配到 @ back to "." Between that here is hit
pattern1 = Re.compile (p1)

What is cloud computing?
This seems to be a cliché and simple question, but it's actually not. Currently, there are hundreds of (or even thousands of) definitions of cloud computing on the web. To fully answer this question, it may be more convenient to understand what is not cloud computing before trying to define it.
Some people say that cloud computing is just another term for the service (SaaS) model of software that has been at th
