Scaling example of an ElasticSpace (Elastic Service Manager - Gigaspaces)

ElasticSapceScale.java

private void scaleByMemory() {

  Admin admin = new AdminFactory().addGroup("elip-xap").createAdmin();

  // discover the space
  space = admin.getProcessingUnits().waitFor("mySpace");

  // scale to 128MB of memery capacity. this means that number of container will be 128/memeoryCapacityPerContainer
  space.scale(new ManualCapacityScaleConfigurer().memoryCapacity(128, MemoryUnit.MEGABYTES).create());
  
}

private void scaleByCpu() {

  Admin admin = new AdminFactory().addGroup("elip-xap").createAdmin();

  // discover the space
  space = admin.getProcessingUnits().waitFor("mySpace");

  // scale so that the processing unit will use 8 cpu cores in total. so if each machine has 2 cores the pu will
  // have to spread to at least 4 machines
  space.scale(new ManualCapacityScaleConfigurer().numberOfCpuCores(6).create());
  
}

private void scaleByEager() {

  Admin admin = new AdminFactory().addGroup("elip-xap").createAdmin();

  // discover the space
  space = admin.getProcessingUnits().waitFor("mySpace");
  
  // scale to utilize the maximum number of cpu's and start as many containers as possible 
  // to reach maximum memory utilization
  space.scale(new new EagerScaleConfig());
