GETTING  RID  OF  IMPEDENCE  

All you need is Map

James Gosling Creator of Java

Map  

import java.util.Map; !import java.util.HashMap;!!Map map = new HashMap();!map.put(“1”, “value”); !map.get(“1”);!

Thread  Safe  Map  

import java.util.Map; !import java.util.concurrent.*;!!Map map = new ConcurrentHashMap();!map.put(“1”, “value”); !map.get(“1”);!

Distributed  Map  

import java.util.Map; !import com.hazelcast.core.Hazelcast;!!HazelcastInstance h;!h = Hazelcast.newHazelcastInstance();!Map map = h.getMap(“mymap”);!map.put(“1”, “value”); !map.get(“1”);!

All you need is JCache

Greg Luck Creator of Ehcache

Co Spec Lead Jsr107 JCache

Hazelcast  leads  standardiza9on  •  Hazelcast  CTO  Greg  Luck  is  the  newest  addi_on  to  the  

management  team    

•  Greg  Co-­‐led  the  standardiza9on  effort  with  Oracle  which  makes  Hazelcast  one  of  the  standard-­‐bearers  

•  Greg  has  credibility  in  this  market  having  founded  Ehcache,  the  world’s  most  popular  Java  cache  

•  Jcache  will  be  released  Mon  March  17th  by  JCP  and  widely  implemented  by  IMDG  vendors  and  embedded  in  Java  EE  8  and  Spring  

•  The  caching  standard  will  expand  IMDG  market  and  adop9on  of  Hazelcast
