2. Agenda GridGain What is Grid Computing and why? What is GridGain and why? Why Java and Open Source? Key Concepts Demos Grid Application in 15 Minutes Running JUnits on Grid GridGain – Java Grid Computing Made SimpleSlide 2

3. Product. Business. People. Slide 3 What is Grid Computing? Compute Grids Parallelize logic execution Data Grids Parallelize data storage Grid Computing = Data Grids + Compute Grids Data Partitioning + Affinity Map/Reduce

4. Product. Business. People. Slide 4 Why Grid Computing? Ask Google, Yahoo, eBay, Amazon Solves problems often unsolvable otherwise Google has almost 1,000,000 nodes in its grid Uniformed programming paradigm that scales from garage to Google This code returns the same result on 1, 2 or 1,000 nodes – only faster, much faster… @Gridify(taskName = "Optimizer") public double optimizePortfolio(Portfolio p) {... }

5. What is GridGain? Grid computing framework Full-stack grid computing Innovative Map/Reduce Integration with leading Data Grids Elegant simplicity Think Spring, Hibernate vs. EJB2 Java centric Built in Java and for Java Open source LGPL/Apache license GridGain – Java Grid Computing Made SimpleSlide 5

6. Why GridGain? Existing projects are: Too complex to use Globus, GridEngine anyone? Too expensive to use $M for DataSynapse, Platform, UD Not Java-based or Java friendly Alien to Java 5 and JEE GridGain – Java Grid Computing Made SimpleSlide 6

7. Professional Open Source GridGain - Professional Open Source Open source FREE software FREE upgrades FREE community support FREE source code No gimmicks Commercial enterprise-level support and services Indemnification Custom SLAs Guaranteed response time Like JBoss, Spring Source, Mule Source… GridGain – Java Grid Computing Made SimpleSlide 7

8. Key Concepts MapReduce Zero Deployment On Demand Scalability Blend-In Integration Transparent Grid Enabling with AOP Data Grids Integration Slide 8GridGain – Java Grid Computing Made Simple

9. MapReduce Slide 9 1.Task execution request 2.Task splits into jobs 3.Result of job execution 4.Aggregation of job results GridGain – Java Grid Computing Made Simple

10. MapReduce Example Slide 10GridGain – Java Grid Computing Made Simple

11. Zero Deployment Peer-to-Peer On-Demand Class Loading technology No Ant scripts to run No JARs to copy or FTP No nodes to restart Develop in EXACTLY the same way as locally Change->Compile->Run on the grid Start many grid nodes in Single JVM – debug grid apps locally (!) Single computer – run grid on your workstation Single biggest developers’ productivity boost Slide 11GridGain – Java Grid Computing Made Simple

12. On Demand Scalability Slide 12GridGain – Java Grid Computing Made Simple

13. Blend-In Integration Checkpoints Failover Collision Resolution Topology management Load balancing Deployment Service Provider Interface (SPI)-based architecture Plug in and customize almost any aspect of grid computing framework LEGO-like assembly of custom grid infrastructure Grid computing framework aspect that are fully pluggable: Slide 13 Communication Discovery Tracing Startup Event storage GridGain – Java Grid Computing Made Simple

14. Blend-In Integration, cont. Application Servers JBoss AS BEA Weblogic IBM Websphere Glassfish Tomcat Data Grids JBoss Cache Coherence GigaSpaces AOP JBoss AOP Spring AOP AspectJ Messaging Middleware Mule JMS ActiveMQ SunMQ Jgroups Email TCP, IP-Multicast Others Spring Junit JXInsight “Out-of-the-box” integration with: Slide 14GridGain – Java Grid Computing Made Simple

15. Transparent Grid Enabling w/AOP 01 class BizLogic { 02 @Gridify(…) 03 public static Result process(String param) { 04... 05 } 06 } 07 08 class Caller { 09 public static void Main(String[] args) { 10 GridFactory.start(); 11 12 try { 13 BizLogic.process(args[0]); 14 } 15 finally { 16 GridFactory.stop(); 17 } 18 } 19 } Slide 15GridGain – Java Grid Computing Made Simple

16. Data Grids Integration Data + Compute Grids = Full stack grid computing Compute grids parallelize processing logic Data grids parallelize data storage Affinity Map/Reduce – ability to co-locate processing logic and the data Minimizes “noise” traffic Optimal grid load and performance GridGain – Java Grid Computing Made SimpleSlide 16

17. Data Grids Integration, cont. GridGain full stack grid computing: GridGain+JBoss Cache Full OPEN SOURCE grid computing platform Native integration GridGain+Coherence Data Grid Native integration GridGain+GigaSpaces Data Grid One compute grid - many data grids Freedom of choice Slide 17GridGain – Java Grid Computing Made Simple
