In the past few years, the innovative development of the open source world has elevated the productivity of Java™ developers to one level. Free tools, frameworks and solutions make up for once-scarce vacancies. The Apache CouchDB, which some people think is a WEB 2.0 database, is very promising. It's not difficult to master CouchDB, it's as simple as using a Web browser. This issue of Java open ...

While the term cloud computing is not new (Amazon started providing its cloud services in 2006), it has been a real buzzword since 2008, when cloud services from Google and Amazon gained public attention. Google's app engine enables users to build and host Web applications on Google's infrastructure. Together with S3,amazonweb services also includes elastic Cloud Compute (EC2) calculation ...

1. DDoS Attack Basics The main purpose of a Distributed Denial of Service (DDoS) attack is to make the specified target unable to provide normal services or even disappear from the Internet. It is one of the strongest and most difficult to defend attacks. According to the way initiated, DDoS can be simply divided into three categories. The first category to win, massive data packets flocked from all corners of the Internet, blocking IDC entrance, so that a variety of powerful hardware defenses ...

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 ...

Hadoop, a distributed computing open source framework for the Apache open source organization, has been used on many of the largest web sites, such as Amazon, Facebook and Yahoo. For me, a recent point of use is log analysis of service integration platforms. The service integration platform will have a large amount of logs, which is in line with the applicable scenarios for distributed computing (log analysis and indexing are two major application scenarios). Today we come to actually build Hadoop version 2.2.0, the actual combat environment for the current mainstream server operating system C ...

In our daily life, we are inseparable from the application of position recognition class. Apps like Foursquare and Facebook help us share our current location (or the sights we're visiting) with our family and friends. Apps like Google Local help us find out what services or businesses we need around our current location. So, if we need to find a café that's closest to us, we can get a quick suggestion via Google Local and start right away. This not only greatly facilitates the daily life, ...

Hadoop is a distributed computing open source framework for the Apache open source organization that has been applied to many large web sites, such as Amazon, Facebook and Yahoo. For me, one of the most recent usage points is the log analysis of the service integration platform. The service integration platform's log volume will be very large, and this also coincides with the application of distributed computing scenarios (log analysis and indexing is the two major scenarios). Today we will actually build a Hadoop 2.2.0 version, the actual combat environment for the current mainstream server operating system C ...
