云计算个人的见解(个人怎么做云计算业务)

What is cloud computing? Should I use cloud computing?

1. Cloud computing
Cloud computing (cloud computing) is the increase, use and delivery model of related services based on the Internet, usually involving Provide dynamically scalable and often virtualized resources over the Internet. Cloud is a metaphor for network and Internet. In the past, cloud was often used to represent telecommunications networks in diagrams, and later it was also used to represent the abstraction of the Internet and underlying infrastructure. Therefore, cloud computing can even allow you to experience 10 trillion calculations per second. With such powerful computing power, you can simulate nuclear explosions, predict climate change and market development trends. Users access the data center through computers, laptops, mobile phones, etc., and perform calculations according to their own needs.
There are many definitions of cloud computing. There are at least 100 explanations for what exactly cloud computing is. The widely accepted definition at this stage is the National Institute of Standards and Technology (NIST): Cloud computing is a pay-per-use model that provides available, convenient, on-demand network access and is configurable. A shared pool of computing resources (resources including networks, servers, storage, application software, services) that can be quickly provisioned with minimal management effort or minimal interaction with service providers.
2. Big Data
Big data (bigdata) refers to a collection of data that cannot be captured, managed, and processed with conventional software tools within an affordable time frame.
In "The Age of Big Data" written by Victor Meyer-Schoenberg and Kenneth Cukier, big data refers to the use of all data for analysis without shortcuts such as random analysis (sampling survey). deal with. The 4V characteristics of big data: Volume, Velocity, Variety, and Value.
3. The relationship between the two:
The focus of big data is data. A large amount of data needs to be successfully analyzed to get its due value. Big data provides analytical value. Cloud computing uses the cloud to bring together many things and provide a service that many people can use. Cloud computing provides value in use. The two are inseparable. The amount of data generated in the cloud is huge. To generate value from the huge data, big data analysis is required.

The understanding and understanding of cloud computing are as follows:

Cloud computing is a type of distributed computing, which refers to The huge data calculation processing program is decomposed into countless small programs through the network "cloud", and then these small programs are processed and analyzed through a system composed of multiple servers to obtain the results and return them to the user.

In the early days of cloud computing, simply put, it was simple distributed computing, solving task distribution and merging calculation results. Therefore, cloud computing is also called grid computing. Through this technology, tens of thousands of data can be processed in a very short time (a few seconds), thereby achieving powerful network services.

The cloud service mentioned at this stage is not just a kind of distributed computing, but also distributed computing, utility computing, load balancing, parallel computing, network storage, hot backup redundancy and virtualization. The result of technological hybrid evolution and leap forward.

Cloud computing refers to a system with extremely powerful computing capabilities formed through a computer network (mostly the Internet), which can store and collect related resources and configure them on demand, providing users with personalized services.

"Cloud" is essentially a network. In a narrow sense, cloud computing is a network that provides resources. Users can obtain resources on the "cloud" at any time, use them as needed, and view them. It is infinitely scalable, and you just need to pay according to usage. The "cloud" is like a water plant. We can receive water at any time, and there is no limit. We can pay the water plant according to the water consumption of our home.
