If one is aware of a specific developer's product, such as the IBM WebSphere, then you will see that the biggest part of its technology is websphere-specific. Compare all developers to Java EE specific improvement, has ...

PaaS (Platform-as-a-service) is a kind of cloud service, the service provider not only provides on-demand hardware and operating system services, but also provides the application platform and solution stack. For developers, PAAs greatly reduces the cost and pain of it deployments, providing resources for applications to scale more easily as needed. JVMs, application servers, and deployment packages (for example, war and ear) provide natural isolation for Java applications, allowing different developers to deploy applications in the same infrastructure, so JAV ...

In this issue of Java Development 2.0, Andrew Glover describes how to develop and deploy for Amazon elastic Compute Cloud (EC2). Learn about the differences between EC2 and Google App Engine, and how to quickly build and run a simple EC2 with the Eclipse plug-in and the concise Groovy language ...

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 ...

VMware suddenly released its first open source Paas--cloudfoundry this April. In the months since its release, the author has been concerned about its evolution and benefited from its architectural design, and felt the need to write to share it with you. This article will be divided into two parts: the first part mainly introduces the architecture design of Cloudfoundry, from the module that it contains, to the information flow of each part, how the modules coordinate and cooperate; The second part will be based on the first part, how to use Clou in your data center ...

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 ...
