Human society has entered the information age, the emergence of the Internet makes the distance between us closer, no matter the ends of the earth, as long as there is a signal, people can contact each other through the Internet. The emergence of cloud computing makes the application of the Internet more extensive and more powerful. But now the Internet is no longer the traditional Internet. What is cloud computing? What are the applications of cloud computing? In the era of cloud computing, how should users choose their own cloud computing solution?

Cloud computing is an Internet-based supercomputing model in which thousands of computers and servers are connected to form a computer cloud in a remote data center. As a result, cloud computing can even allow you to experience 10 trillion computing power per second, with such powerful computing power to simulate nuclear explosions, predict climate change and market trends. Users access the data center through computers, notebooks, mobile phones and so on, and carry out data operations according to their own needs.

The basic principle of cloud computing is that by distributing computing on a large number of distributed computers rather than local computers or remote servers, the operation of enterprise data centers will be more similar to the Internet. This enables enterprises to switch resources to the applications they need and access computers and storage systems according to their needs. The "cloud" of cloud computing is the resources that exist on the server cluster on the Internet. the local computer only needs to send a demand information through the Internet. there will be thousands of computers at the remote end to provide you with the resources you need and return the results to the local computer, so that the local computer hardly needs to do anything, and all the processing is done in the computer cluster provided by the cloud computing provider.

After understanding cloud computing, how should enterprises choose their own "cloud"? We all know that cloud services are now divided into private cloud, public cloud and hybrid cloud, so how should users choose?

Public cloud

For many enterprises, public cloud is the most typical choice of enterprise cloud computing. The public cloud is suitable for both small and large enterprises, such as Microsoft's Office 365. the cost advantage is obvious. Traditional Office product components require every enterprise user to have a license, and the capital investment needed to purchase the license will be depreciated as enterprise capital expenditure. However, if the enterprise business adjustment does not need so many user licenses, he will not be able to get a refund from Microsoft.

Private cloud

Because the private cloud is designed to serve within the company, whether it is operated by its own or run by a third-party partner, it can have more freedom to customize software functions and business processes, and the specific functions and business processes are malleable. Upgrades and operations can also be based on the user's schedule, which is often difficult to achieve in the public cloud.

Hybrid cloud

Some businesses can benefit from using multiple clouds. For example, you may have a private cloud deployed within the enterprise that runs a highly proprietary business application, but you can also use Office 365 and financial management applications on the public cloud.

The IT management team or technical consultant can evaluate the technology being used, create a business case, and deploy the application on different clouds to achieve optimal resource allocation. Configuring private or public clouds is mainly based on security and control requirements, as well as an assessment of the skills and capabilities of your IT team. If you have a small IT team, you may not be able to manage large data centers or complex financial applications in a private cloud environment.

Although the mixed environment may be complex, users don't have to worry about it, because all the complexity is behind the scenes. By means of single sign-on, the hybrid environment can make users feel like maintaining and using a completely own system.

I believe that after my explanation above, you already have a certain understanding of cloud services, so when you choose, you can choose your own cloud services according to your actual needs.
