The Master-Worker Pattern
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 … Continue reading
JavaOne 2009 Lab – PetClinic in the Clouds
This year JavaOne will include really cool lab – PetClinic in the Clouds: Scaling a Classic Enterprise Application. In this Hands-on Lab, participants will take a popular Web application (the Spring PetClinic sample application) and modify it so that it … Continue reading
Performance, Performance, Performance
Speed as they say is relative. It is great tearing along the road in a 180 mph Ferrari, bit if you don’t care then you will be happy poodling along at 50 mph. In most of the industries or companies I work in however speed is of the essence. Fast is good, faster is better, faster than that is even better…
Some examples….one of the companies I sold to in late 2007 was a post trade reconciliation company that used GigaSpaces to build their next generation trade reconciliation system, replacing their existing C++ system. Why ? Because ever increasing trade volumes meant they had to have an infinitely scalable system for their clients and their existing system could not cope. They put GigaSpaces XAP through rigorous tests to prove that by doubling the amount of CPU’s each time they got near linear scalability. Needless to say GIgaSpaces passed that test and the new system is now being pushed out to their clients. Prior to using a GigaSpaces designed system it took 8 minutes to process 1 million Trades. It now takes 42 seconds….
In the first quarter this year we closed business with a Bank in which GigaSpaces is being used to interface with a trading system (a multi-asset class solution for treasury and capital market participants) to speed up reading of trade data. Simple Trade queries that were taking minutes are now delivered in seconds, and complex Trade queries that were taking 30 minutes or more are now being delivered in around 45 seconds……
In an earlier post I outlined a poll I had set up on LinkedIn that asked the question “What is you or your organisation’s single biggest concern about deploying applications to the Cloud ?”. I promised to post the results, which you can now see below:
Surprise, surprise, it is performance. It will come as no surprise to you that the performance gains that are experienced by GigaSpaces users in private Data Centers are also experienced in the Cloud. GigaSpaces for the EC2 cloud performs with minimum latency and maximum performance. Why ? The GigaSpaces solution is managing data in memory and ensuring it is co-located in the same cloud node as the relevant business logic making for lightening fast performance.
Performance….if you need it you know where to look……
