There are two main ways to store data: Database and filesystem, and the object-oriented storage are developed behind, but the overall thing is to store both structured and unstructured data. DB is initially serviced for structured data storage and sharing. FileSystem storage and sharing is large files, unstructured data, such as pictures, documents, audio and video. With the increase in data volume, stand-alone storage can not meet the needs of structured and unstructured data, then in the era of cloud computing, there is a distributed ...

Explore cloud computing and the various cloud platforms offered by key vendors such as Amazon, Google, Microsoft® and Salesforce.com. In part 1th of this three-part series, we'll give you a typical example of an enterprise application that uses a JMS queue, and look at what will be involved in using a part of this JMS infrastructure in the cloud. ...

Shrinking to achieve, in Alibaba's 2017 double 11 singles day, our domestic trading unit used cloud resources to sharpen and expand at the peak, and after the spike, the expansion resources will be returned to the cloud, but in the actual operation, we really want What can we do to get the resources to the cloud when we need it, and go smoothly when we don't need it.

Before introducing the microblogging recommendation algorithm, let's talk about recommendation systems and recommended algorithms. There are some questions: what scenarios does the recommendation system apply to? What are the problems and what value are they used to solve? How is the effect measured? The recommendation system was born very early, but was really valued by everyone, originated from the "Facebook" as the representative of the rise of social networks and "Taobao" as the representative of the prosperity of the electric business, "choice" of the era has come, information and items of great wealth, so that users such as the vast universe of small points, at a loss. The recommendation system ushered in an outbreak of opportunity to become closer to the user: fast ...

Blockchain is currently a relatively popular new concept, containing two concepts of technology and finance. From a technical point of view, this is a distributed database that sacrifices consistency efficiency and guarantees eventual consistency. Of course, this is one-sided. From an economic point of view, this kind of fault-tolerant peer-to-peer network just meets a necessary requirement of the sharing economy - a low-cost trusted environment.

Through the introduction of the core Distributed File System HDFS, MapReduce processing process of the Hadoop distributed computing platform, as well as the Data Warehouse tool hive and the distributed database HBase, it covers all the technical cores of the Hadoop distributed platform. Through this stage research summary, from the internal mechanism angle detailed analysis, HDFS, MapReduce, Hbase, Hive is how to run, as well as based on the Hadoop Data Warehouse construction and the distributed database interior concrete realization. If there are deficiencies, follow-up ...

As a new computing model, cloud computing is still in its early stage of development. Many different sizes and types of providers provide their own cloud-based application services. This paper introduces three typical cloud computing implementations, such as Amazon, Google and IBM, to analyze the specific technology behind "cloud computing", to analyze the current cloud computing platform construction method and the application construction way. Chen Zheng People's Republic of Tsinghua University 1:google cloud computing platform and application Google's cloud computing technology is actually for go ...
