Clustered storage has a role to play in improving IBM i availability under some scenarios, but there are network implications. This article examines these important issues.
By Bob Swift
An increasing number of organizations are at least considering the use of clustered data storage, a technology that has network implications when used in a multi-site configuration. The network implications are often not fully understood and may lead to failed implementations or unexpected costs. The purpose of this article is to help build that understanding.
SOA in 2008 Service-Oriented Architecture is more than a buzzword.
By Joe Pluta
I've been writing about Service-Oriented Architecture (SOA) for some time now. I did a complete review of the state of the technology in an article I wrote back in November of 2004. In that article, I commented that SOA is really the latest version of client/server technology, except that it had already been saddled with a couple of pieces of ungainly baggage, namely Simple Object Access Protocol (SOAP) and Universal Description, Discovery, and Integration (UDDI). In the article, I noted that UDDI was useless and that SOAP had a couple of contenders, and I predicted that SOA would evolve away from reliance on those technologies.
