The IBM WebSphere Developer Technical Journal is now the IBM Middleware Technical Journal for Developers. This new issue contains two sets of articles that spotlight two high profile players in two established technical areas. One group looks at the IBM PureApplication product group and its relationship to all types of cloud scenarios, and the other looks at the IBM WebSphere Application Server Liberty profile and its relationship to other application platforms - including traditional WebSphere Application Server.
How does PureApplication fit in the field of public, private, and hybrid cloud scenarios? In addition to explaining why PureApplication System, PureApplication Software, or PureApplication Service should be your enabler of choice for whatever type of cloud you have, this tutorial also happens to be a super primer on all things cloud computing.
This tutorial explains how to setup a management domain and deployment subdomain using IBM PureApplication System, also covering applicable requirements and restrictions.
Change Data Capture and WebSphere eXtreme Scale: Architectural patterns for dealing with stale data in a distributed caching environment
This tutorial outlines various architectural patterns, including a new approach based on the principles of Change Data Capture. The IBM WebSphere eXtreme Scale CDC Adapter is a new feature offered in WebSphere eXtreme Scale V126.96.36.199 that provides a solution to stale cache scenarios based on the IBM InfoSphere Data Replication CDC product.
In the third and final installment of this series, you will follow the process discussed in Parts 1 and 2 to migrate a JBoss application to the IBM WebSphere Application Server Liberty profile - without incident. One of the steps will be to use the Liberty Technology Preview to identify any porting issues so you can quickly decide if an application is a good fit for the Liberty lightweight container.
The WebSphere Contrarian: If liberty means freedom of choice, am I free to choose the Liberty profile?
Since its introduction in 2012, the IBM WebSphere Application Server Liberty profile has rapidly evolved from a development desktop focused runtime to one that is increasingly being considered for production deployment. The WebSphere Contrarian clears up some misconceptions about the Liberty profile.
WebSphere Application Server (and products built on top of WebSphere Application Server) stores system account passwords in a variety of files within the WebSphere Application Server profiles file structure. WebSphere Application Server provides an SPI for customizing the processing of these system passwords. This article described an IBM Software Services for WebSphere custom implementation of this SPI.
