Several articles in the series cover the deployment of Hadoop, distributed storage and computing systems, and Hadoop clusters, the Zookeeper cluster, and HBase distributed deployments. When the number of Hadoop clusters reaches 1000+, the cluster's own information will increase dramatically. Apache developed an open source data collection and analysis system, Chhuwa, to process Hadoop cluster data. Chukwa has several very attractive features: it has a clear architecture and is easy to deploy; it has a wide range of data types to be collected and is scalable; and ...

Now almost any application, such as a website, a web app and a mobile app, needs a picture display function, which is very important for the picture function from the bottom up. Must have a forward-looking planning picture server, picture upload and download speed is of crucial importance, of course, this is not to say that it is to engage in a very NB architecture, at least with some scalability and stability. Although all kinds of architecture design, I am here to talk about some of my personal ideas. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

1 compression in general, the computer processing of data exist some redundancy, at the same time, the data, especially the correlation between adjacent data, so you can through some different from the original encoding of the special encoding method to save data, so that the data occupy a small amount of storage space, this process is generally called compression. The concept of compression corresponds to decompression, the process of restoring compressed data from a special encoding to the original data. Compression is widely used in mass data processing, compression of data files, can effectively reduce the space required to store files, and speed up data on the network or to ...

The pricing of cloud storage is the same as the pricing of some tools. For a long time, almost all manufacturers are repeating the same slogan: "Users only pay for what they use." 　　The price range for public cloud storage is 12% to 25% per gigabyte a month. However, the real cost-saving aspects of cloud storage are likely to be linked to the ability to solve the incidental costs of enterprise users, who need to store their own data in the cloud. "Some companies that need to manage their data find they can get out of the data center, and they are gradually beginning to succumb ...
