The Zope default provides an FTP service, a file-based protocol. This immediately triggers a way to represent the object to the file system and reverse the mapping. In order to complete the mapping in a flexible and replaceable way, a series of interfaces can be implemented as adapters to provide a representation that the FTP Publisher understands. This chapter shows how to implement some interfaces for a custom file system representation. One thing you might be confused about: "Why do we have to write our own filesystem support?" Zope cannot provide some implementations by default ...

How should Microsoft Windows Azure be defined? This is not an easy question to answer, and now it seems more so, and recently Microsoft has added new online services to Azure. Compared to other cloud platforms, the previous Azure short board is embodied in the service of online building applications. But this week Microsoft has made up for the lack of azure, and Microsoft has released a series of cloud services.

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. For the picture server IO is undoubtedly the most serious resource consumption, for web applications need to picture service ...

One of the features of cloud computing is the ability to move applications from one processor environment to another. This feature requires a target operating system to receive it before moving the application. Wouldn't it be nice if you could automate the installation of a new operating system? A well-known feature of the intel™ architecture system is the ability to install Linux automatically. However, installing Linux automatically is a tricky issue for System P or IBM power BAE using the hardware management console. This article discusses the solution of ...
