“You just can't have it all” is a phrase that most of us are accustomed to hearing and that many still believe to be true when discussing the speed, scale and cost of processing data. To reach high speed data...

The next big thing in big data: fast data

By |2020-10-26T08:51:11+00:00June 26, 2014|

The big data movement was pretty much driven by the demand for scale in velocity, volume, and variety of data. Those three vectors led to the emergence of a new generation of distributed data management platforms such as Hadoop for...

Moving away from Mainframe to Commodity – How?

By |2020-10-06T07:17:13+00:00December 14, 2011|

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 [...]

Last year I wrote a post titled Platform as a Service: The Next Generation Application Server? where I was referring to the shift from application server into platforms. On my 2011 predictions I referred to a new emerging PaaS category...

Possible Impossibility – The Race to Zero Latency

By |2020-10-06T10:44:48+00:00December 6, 2010|

I recently read a book called: "Physics of the Impossible" by the theoretical physicist Michio Kaku. Dr. Kaku lists "Possible Impossibilities" and classifies these into different categories where all these "impossibilities" may happen in the near/distant future. When talking about "zero latency", I consider this something we can achieve today. The [...]

NoCAP Part III GigaSpaces clustering explained..

By |2020-10-06T10:46:20+00:00November 29, 2010|

In part-I of this post I tried to suggest a scalable architecture that can deal all three properties of CAP. Part II goes back to the definition of Availability and Partition tolerance and the different views on that regard. In...

new and modified best practices

Our best practices wiki is growing rapidly and full with good and useful material. Here are few new best practices added lately: - Finding Partition Load – routing data based on partition load. - Even Data Distribution – simple example explains how to evenly partition application data. - WAN Replication Gateway – Simple blueprint for WAN replication scenario [...]

Scale-out vs Scale-up

By |2020-10-06T11:20:34+00:00September 1, 2010|

In my previous post Concurrency 101 I touched on some of the key terms that often comes up when dealing with multi-core concurrency. In this post I'll cover the difference between multi-core concurrency that is often referred to as Scale-Up...

7.0.1 – One giant step for XAP.NET

By |2020-10-06T12:13:11+00:00September 17, 2009|

Even though 7.0.1 is considered a minor version, when it comes to XAP.NET, it offers very powerful set of new features which improve the initial user experience, better monitoring capabilities and most importantly, exposing remote services over the grid. I feel very confident by saying that 7.0.1 XAP.NET offers a [...]

The Master-Worker Pattern

By |2020-10-07T07:02:58+00:00August 24, 2009|

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 [...]
