There is a concept of an abstract file system in Hadoop that has several different subclass implementations, one of which is the HDFS represented by the Distributedfilesystem class. In the 1.x version of Hadoop, HDFS has a namenode single point of failure, and it is designed for streaming data access to large files and is not suitable for random reads and writes to a large number of small files. This article explores the use of other storage systems, such as OpenStack Swift object storage, as ...

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.

With the development of cloud computing in China, more and more cloud computing products emerge. However, due to the sharing of public cloud computing resources and the essential idea of resource scheduling, the importance of security in public cloud computing is obvious. Users start to worry about whether the code is safe, the data is secure, and the transmission is secure. The platform provider should also guard against DDoS, prevent misuse of resources, and prevent the use of Web language vulnerability attacks. At the QCON2012 Global Software Development Conference, Sina Cloud computing chief architect Conglei introduced, "Sina app Engin ...
