Human beings are powerful. They can not only invent things that are not in nature, but also strengthen and upgrade existing ones. Nowadays, when cloud computing is spread all over the street, the new concept will bring a new round of impact. People need to put forward the most advanced technology in the process of constant impact. The next mainstream of cloud computing is probably not "cloudy".
We live in a world that likes to name things. In the case of cloud computing, these names revolve around usage patterns: public, private, and hybrid. Now there is a new term, mulTIcloud, to describe an emerging cloud computing usage model.
“Cloudy†refers to the use of more than one public cloud. This pattern occurs when companies try to avoid relying on a single public cloud provider when they choose the specific service for each public cloud to get the best results, or both.
Definition: "Cloudy" and "Mixed Cloud"
So what is the relationship between cloudy and hybrid clouds? Some people use two words to replace each other, but they have a clear meaning. The relative of hybrid and private clouds (cloud-based local data centers) and public clouds.
If you use multiple public and private clouds together, it's still a cloudy environment. (Some people may call it mixed and cloudy, which is also good.)
Definition of "practical hybrid cloud"There is also a "beast" called the Practical Hybrid Cloud, which is a mix of traditional enterprise data centers and public clouds; the existence of a practical hybrid cloud is because many companies are disappointed with private clouds and seek to have what they already have and the public. The way clouds are combined.
In contrast, a cloudy architecture uses two or more public clouds.
What is behind the cloudy trend?As a trend, cloud computing is becoming more and more complex. The vision of a few years ago was to put the workload on a single cloud, whether it was a public cloud or a private cloud. But then the hybrid cloud architecture became more attractive because it gave businesses more choices.
Enterprise IT wants this choice because both Google and Microsoft have developed compelling public cloud platforms that provide an alternative to Amazon Web Services, which opens public cloud services. Other enterprise providers -- including IBM, HP Enterprise, and, more recently, Oracle -- have joined the battle group, albeit far less successful.
Since these are viable public cloud options, companies are beginning to adopt formal architectural processes and “shadow ITâ€â€”groups in the enterprise can use public clouds in this way without the need for enterprise IT knowledge – combining them together. Various shadow ITs often pick different public clouds and then hope that these cloud operations are managed by enterprise IT.
No matter how you come here, most companies now manage a cloudy infrastructure.
While many IT organizations use only the native tools and services provided by each cloud vendor to manage these complex cloudy environments, some organizations are becoming smarter and abstracting themselves from complexity.
By using tools such as Cloud Management Platform (CMP) and Cloud Service Agent (CSB), organizations can manage multiple clouds as if they were a cloud. However, the price to pay for this is that you can only use a subset of the features of each cloud; that is, take the "least common denominator" approach.
In the rectifier circuit; the use of diodes in series can increase the back pressure withstand value (usually the sum of the back pressure of all diodes, but it is best to use diodes of the same specification).
In the voltage stabilization circuit; the series connection of the diode is equal to the sum of the voltage stabilization value of the diode. The use of diodes in parallel is theoretically the sum of rated currents, but considering that it is impossible to be absolutely symmetrical, they can only be used below 80% of the total.
TVS transient suppressor diodes work in the same way as regulator diodes, but there are structural differences.The biggest difference is that the PN junction area composed of the general regulator diode is very small, it can withstand the reverse current is small.
