There are often misconceptions about the relationship between big data and cloud computing. 　　And they will be mixed up to say, do one sentence of a straightforward explanation is: cloud computing is the virtualization of hardware resources, large data is the efficient processing of massive data. Although the above sentence explanation is not very appropriate, but can help you to understand the difference between the two. In addition, if you do a more vivid explanation, cloud computing is equivalent to our computer and operating system, will be a lot of hardware resources virtualization after the allocation of use, in the field of cloud computing is now the boss of Amazon, can ...

Decentralized structured storage System--cassandra Li Yu Cassandra is a distributed storage system that can be used to manage huge amounts of structured data distributed across a large number of inexpensive server systems, while providing high availability services with no single point of failure. Cassandra is designed to run on an infrastructure consisting of hundreds of nodes, which may be distributed across a number of different data centers, and when the nodes reach this size, a large and small component failure can occur frequently. Cassandra face these failures when managing persistent state ...
