"51CTO exclusive feature" 2010 should be remembered, because the SQL will die in the year. This year's relational database is on the go, and this year developers find that they don't need long, laborious construction columns or tables to store data. 2010 will be the starting year for a document database. Although the momentum has been going on for years, now is the age when more and more extensive document databases appear. From cloud-based Amazon to Google, a number of open-source tools, along with the birth of Couchdb and MongoDB. So what ...

"At present, it is getting softer", don't think, this sentence is used to describe the development trend of enterprise IT architecture, to summarize the cloud computing era software definition of all the characteristics of the times is not too much. The imperative of storage virtualization of course, this is the demand of many enterprises, they want to make better use of the existing limited budget by consolidating the physical architecture and using more virtual servers to reduce the cost of server hardware. Although a lot of software and hardware vendors in the server virtualization has come up with a very mature solution, but, to today's traditional virtual ...

The hardware environment usually uses a blade server based on Intel or AMD CPUs to build a cluster system. To reduce costs, outdated hardware that has been discontinued is used. Node has local memory and hard disk, connected through high-speed switches (usually Gigabit switches), if the cluster nodes are many, you can also use the hierarchical exchange. The nodes in the cluster are peer-to-peer (all resources can be reduced to the same configuration), but this is not necessary. Operating system Linux or windows system configuration HPCC cluster with two configurations: ...
