What is the essential difference between cloud computing and grid computing?

are you sure you know more about cloud computing?

know what cloud computing is, and you will know!

at present, cloud computing is a new thing, and risks and opportunities of new things coexist.

Express it in a straightforward way:

Cloud computing is to integrate resources to provide services in a timely manner, which mainly embodies technology and services at three levels.

one is the hardware infrastructure level, which allows hardware resources to provide services in a timely manner;

(customers want hardware environment resources, log in to the resource pool to customize them, then pay the money, and finally get the resources, and pay as much as they want;

the payment targets are: application developers, enterprise IT managers, application platform suppliers, etc. ）；

one is the application platform level, which allows the application platform to provide services in a timely manner;

(The supplier improves the software platform, which can develop, deploy, manage and monitor applications, and provide an open APP-like store;

the payment target is: application developers. )

One is the application level, which allows applications to provide services in a timely manner;

(application vendors deploy applications on application platforms, so that users can use these applications, enjoy services and pay fees in a timely manner;

the target of payment is the end consumer. )

Just-in-time service:

Like hydropower, from the time you start using it to the time you end using it, you can use the application directly by logging in to the application portal.

You don't even need to install the application locally, just like turning on the tap and then paying for it. It is essentially a service and profit model that pushes

.

therefore, there are many ways to learn from cloud computing.

However, their fundamental foundation is computer science and technology, including network, hardware, software, etc.

Only hardware or platform will pay more attention to technologies such as virtual machine, grid computing, distributed computing, etc.

While applications will pay more attention to user experience and mass internet, the main application technology is open software technology, and

they may be particularly interested in the development of WIFI mobile applications for android or ios or wm.

the next wave of IT is cloud computing, internet of things, artificial intelligence and biotechnology.

At present, cloud computing is a new thing, and the shortage of teaching resources is normal. The risks and opportunities of new things coexist.

Please believe that the opportunity has really passed through this village. Without this store, cloud computing is just like the initial computer major.

When it matures, when you see its development, you will fall behind and have to pick up cigarette butts behind your predecessors.

Take advantage of the opportunity to study this major. At present, cloud computing is in the early stage of development, and it's just a good time for you to graduate!

I believe that choosing this new industry is risky, but the opportunity always goes to the first person who dares to eat crabs.

specifically,

grid computing: a kind of distributed computing, a super virtual computer composed of a group of loosely coupled computers. Many cloud computing deployments depend on computer clusters (but it is quite different from the composition, architecture, purpose and working mode of the grid).

but in terms of implementation, grid computing can be one of the important technical foundations of cloud computing, especially in IAAS.

after all, one of the most valuable ideas of cloud computing is to integrate resources and make the best use of them.
