The commercial use of the five private cloud and public cloud

Basically any business discussion of cloud services is essentially a system that is known as "legacy"-those that are fixed on infrastructure and bundled with networks, storage and tasks ("fussy" ERP and financial functions) are going to fade away.

As a result, raising the private cloud to the next level is the same as building a new public cloud service. The crux of the matter is what situations and environments use a public cloud or a private cloud to achieve the best results (in fact, all clouds are the same, and here only from clouds and public clouds).

The executive vice president of Switch Data Center Tech, Mark Thiele, summarizes a very good business case summary here.

The public cloud service applies to the following 5 places:

Where infrastructure investments are severely constrained, such as large hosts, and investment in enterprise applications. IT support is often mentioned in fast software development, virtual automation, optional services, or open source. Small business with high elasticity and sensitivity in decision-making. Make quick transitions and tags for new applications. IT staff are not disgusted by the reliance on server work or storage-they are not considered to be threatened because they rely on external vendors.

The private cloud is suitable for the setting up of:

A company that has a ten-year plan for IT support, infrastructure design, and enterprise application investment. There are stringent and broader requirements for management and financial control, and companies that pose significant risks in the event of an error. Companies that slow business change to avoid risk. Personnel organizations with special rules are not able to achieve rapid convergence when critical infrastructure or applications change. A larger infrastructure allows "deeper employees to just and improve economies of scale".

Of course, there are companies that use a mix of public and private cloud services, or rely on external vendors to organize more professional and user-owned resources. Of course, in order to better meet the needs, enterprises may also use external and their own technology to improve the service. After reaching a certain level, it may also become a cloud supplier's identity-and that's a different story, of course.
