Every software system has logging requirements so application processing can be monitored and tracked. Modern distributed systems, which are usually based on application frameworks, require a logging solution that can cope with multiple processes on multiple hosts sending logging information to a single logging service. Many application frameworks widely used today, whether they're high-level frameworks like J2EE application servers or low-level frameworks like CORBA ORBs, don't provide a distributed logging facility for application code. Using JMS queues to log application messages is a portable, framework-independent way to efficiently log messages in a distributed system. Distributed Logging Solutions It's usually a given that a distributed application needs to keep a centralized application log. We've seen many ad hoc solutions, which are often implemented on ...

Service Platforms Emerge as the Foundation for SOA

Enterprise software architectures are shifting from collections of applications that are designed around user interfaces to assemblies of reuseable services. The first step in the evolution toward service-based applications was the definition and publication of services encapsulating discrete business functions. The second wave used services in point-to-point combinations using protocols aimed at system interoperability for communication. The next wave of SOA adoption will focus on enabling composite service definitions that combine domain-specific languages for process orchestr... (more)
