Big Data And Cloud Storage

How big on earth is big data？ What kind of storage is cloud storage？ In the new internet era， these words make us feel overwhelmed. By Zhang Lifeng

How big is big data？

Big data is the data set which cant be captured， managed or disposed by conventional software tools within a certain time. The big data technique is a capability to get valuable information rapidly in different types of data. The techniques adapted to big data includes the Massively Parallel Processing （MPP） database， data mining grid， distributed file system（DFS）， distributed database（DDB）， cloud computing platform， internet and scalable storage systems.

Big data has the following four characteristics： great scale， high value， multiplexing and holographic visible.

What can big data do

The application examples of big data include big science， RFID（Radio Frequency IDentification）， sensor network equipment， astronomy， aerology， genomics， biology， big society data analysis， the internet file processing， making the internet search engine index， communication record details， military reconnaissance， SNS， commuting time prediction， medical record， photo image and image storage， as well as big scale of e-business， etc.

Big data is not only a state of vast amounts of data， and its corresponding data processing technique， but also a way of thinking， an important infrastructure. It may be an edge tool for us to manage the “city disease” such as traffic congestion， haze weather， medical care and food safety in the future. It will also open a larger window for the government to know the public opinions.

Is cloud storage

a kind of memorizer？

Cloud storage is a kind of system， which uses the functions of cluster application， grid technology or distributed file systems， gather different kinds of storage devices in the network together with application software， and then makes them work together to provide data storage and access to business.

The core of cloud storage is the combination of application software and the storage device， which turning the storage device to storage service. The concept of cloud storage is similar to that of cloud computing. It uses the functions of cluster application， grid technology and distributed file systems， gather different kinds of storage devices in the network together with application software， and then makes them work together to provide data storage and access to business. The connotation of the cloud storage is the storage virtualization and storage automation.

Is cloud storage safe？

After the concept of “cloud” was put forward， safety became the main point people focus on. For the vast majority of users， they dont want their own cloud storage turn into a public resource platform， not to mention turning their privacy into popular journalism. Therefore the storage providers have also been sparing no efforts to advertising the safety of their products.

Migrating the data to the cloud will cause the users data safety and usability limited by its cloud storage server suppliers. You can say that the concern about the safety and availability is an important factor， which determines whether the enterprises and individuals will use cloud storage or not.
