computing?
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.

future, however, we can also see the future development and business opportunities of the C/S architecture.

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.

user is the real owner of cloud computing.
Cloud computing applications include the idea of combining power for each of the members.
Several forms of cloud computing
SaaS (software as a service) this type of cloud computing transmits programs to thousands of users through a browser. In the eyes of users, this will save the cost of server and software authorization; from the supplier's point of view, it is enough to maintain only one
platform that allows you to customize composite applications and business processes. ISB is also a software as a service (SaaS)
Example. For example:
The core ISB concept is based on the unified Resource Identifier (URI. Each application service is registered,"Owns" A identifier similar to URI: http://isb.net/daveandteam. To facilitate publishing/subscription.An ISB application developed by developers by connecting to URIs policies and functions (I

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)
print Pattern1.findall (key)
Output results

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

For more than 10 years, a nightmare lingering in the minds of m$ executives has been that one day, perhaps the browser will replace Windows,windows itself will no longer matter. No one really needs windows anymore, they just need a browser.
When Netscape's browser first supported Java applets more than 10 years ago, there were prophets who said a new era was about to begin, and in this new era all applications were built on browsers and Windows was no longer important. M$ felt a huge threat, us
