Moving away from Mainframe to Commodity - How? Mainframe (Z/OS) based systems running COBOL programs are legacy systems in many organizations. These are planned to be replaced with low cost commodity servers running Java or .Net based systems, saving the cost of the expensive mainframe MIPS and COBOL-based development. Using [...]
Security has always been one of those topics that we as developers or architects hate to deal with. Our ideal world would be that security is dealt with at some higher level in our data-center, and that we don't need...
Last week I had an interesting "incident" that proved how much the operational aspects of a virtualized middleware platfrom GigaSpaces provide is critical for on-line systems. Here is the story: During the maintenance activities of one of the largest wall street financial services companies we have as a customer they [...]
The Master-Worker Pattern (sometimes called Master-Slave pattern) is used for parallel processing. It follows a simple approach that allows applications to perform simultaneous processing across multiple machines or processes via a Master and multiple Workers. In GigaSpaces XAP, you can implement the Master-Worker pattern using several methods: - Task Executors [...]

I was very pleased to read an email from Leonardo, who was the winner of the OpenSpaces Developer Challenge (a worldwide programming contest using the Gigaspaces application server which was held last year), saying that he is now a finalist...
MuleSource is a rather popular open source ESB implementation. What I particularly liked about it when I first saw it is how simple it is to glue different services that are communicating in different protocols in a very simple way...
I’ve been reading this nice post from Daniel Gradecak's blogs. He is asking interesting questions about how architects building their systems and how JavaSpaces and SBA are used when designing distributed systems. See my comment as a feedback to his questions. Thank you Daniel for this post! Shay
GigaSpaces XAP.NET 6.6.2 comes with out of the box event listener container abstraction that decouples the business logic implementation from the underlying data grid implementation. This allows simpler and faster processing unit implementation, without having to implement the event triggering logic by your self. For those of you who are [...]
GigaSpaces 6.5 was released at the end of June, and we are now working on the 6.6 release, with the first milestone already publicly available. These are major milestones in a series of upcoming releases all aimed at strengthening our...
A common issue I’m facing recently is how to integrate existing tier-based applications with GigaSpaces persistency service, AKA persistency as a service (Paas) or mirror . The motivation is often a result of the acknowledgment that a standard tier based application fails to scale when facing the database throughput limitation. [...]
I haven't posted in a long time, but today I came back with a bang. The uber-blog GigaOm posted a blog I wrote as a guest columnist. Thanks to Om Malik, Surj Patel and Carolyn Pritchard for all their help....
There have been many separate discussions about SOA and virtualization. Only a few addressed how they relate to each other. Interestingly, while I was working on this post, Geva Perry brought to my attention Judith Hurwitz’s blog - Is Virtualization...
