How many do you know about smart home cloud computing?

Recognition and calculation

Cloud is a metaphor for the Internet and the Internet. Cloud computing is an important computing environment that supports IoT smart homes. It is mainly based on the increase, use, and delivery of Internet-related services. It usually involves the provision of dynamically scalable and often virtualized resources over the Internet.

There are many definitions of cloud computing, and what is widely accepted at this stage is the definition of the National Institute of Standards and Technology (NIST): Cloud computing is a pay-per-use model that provides usability and convenience. , on-demand network access, into a configurable pool of computing resources (resources include networks, servers, storage, applications, services) that can be quickly provisioned with minimal administrative effort or service Vendors perform very little interaction. To understand cloud computing, first pay attention to the main features of cloud computing.

1. Cloud computing is a new computing model

It is a product of the new era and is a new type of computing model based on the Internet. It provides resources such as data, computing, and applications through the Internet to users. In the “cloud” computing environment, users do not need to have professional knowledge and do not need to understand various details in the “cloud”. They only need to pay attention to what they really need and how to obtain the desired resources and services through the Internet. . This is a relatively open environment where user-centered thinking is better reflected here.

2. Cloud computing is a commercial implementation

In the Internet world, we call the network that provides resources "the cloud." In the Internet age, thousands of computers and network servers are connected to data centers that can be stored and calculated by professional network companies to form "clouds." For users, the resources in the "cloud" can be infinitely extended. As long as you access the data center, you can access, use, and expand on-demand computing and storage resources. Some of these resources are free, while some are It's a fee. When necessary, you need to pay for the resources you use. The Internet computing model is thus commercialized in this way.

3. The 5 advantages of cloud computing

One advantage is that it has a straightforward scale. Google Cloud Computing has more than 1 million servers, and Amazon, IBM, Microsoft, Yahoo, and others all have hundreds of thousands of servers. Enterprise private clouds typically have hundreds of thousands of servers. "Cloud" can give users unprecedented computing power.

Advantage two is extremely cheap. "Cloud"'s special fault-tolerant measures can use extremely inexpensive nodes to form the cloud. "Cloud"'s automated and centralized management eliminates the need for high-cost data center management costs for a large number of companies. The versatility of the "cloud" makes it more resource-efficient. The traditional system has been greatly improved, so users can fully enjoy the low-cost advantages of the "cloud", often only a few hundred dollars, a few days to complete tasks that previously required tens of thousands of dollars, a few months to complete.

Advantage III. On-demand service. "Cloud" is a resource library, and this open resource library is "user choice-centered." Cloud services are usually "lease" and are based on per-user pricing instead of purchasing a complete set of services. Users use cloud computing to store on computing resources on demand, paying only for the processing power and storage they need.

Advantage IV: Cloud computing does not target specific applications. Under the support of "cloud", it is possible to construct ever-changing applications. The same "cloud" can support different applications at the same time.

Advantage 5: Stronger scalability. The scale of "cloud" can be dynamically scaled to meet the needs of applications and user scale growth.
