Amazon-ElasticCache

Amazon ElastiCache

Amazon ElastiCache is a web service that makes it easy to deploy, operate, and scale an in-memory cache in the cloud.

The service improves the performance of web applications by allowing you to retrieve information from a fast, managed, in-memory caching system, instead of relying entirely on slower disk-based databases.

Amazon ElastiCache is protocol-compliant with Memcached, a widely adopted memory object caching system.

There are several merits of using elastic catch. There are, simple to deploy , easily managed , compatible , designed for use with other Amazon Web Services , secure and cost effective.

Amazon ElastiCache Functionality:

• Use the Amazon ElastiCache APIs to launch a Cache Cluster selecting a Cache Cluster Name, Cache Node Type and Number of Nodes that best meets our needs.
• Connect to your Cache Nodes using your favorite Memcached clients or Programming language.
• Get detailed monitoring statistics of our Cache Nodes for no additional charge via Amazon CloudWatch.
• If at any point we need additional capacity, we can add more Cache Nodes to our Cache Cluster with a simple API call.
• Pay only for the resources you actually consume, based on our Cache Node hours used.

Features:

• Pre-configured Parameters
• Automatic failure detection and recovery
• Detailed Monitoring and Metrics
• Automatic Software Patching
• Push-Button Scaling

Amazon ElastiCache Cache Node Types:

• Micro
• Standard
• Enhanced
• High-Memory
• High-CPU

Lets see a sample Java Code for this implementation, 

import net.spy.memcached.MemcachedClient;
import java.net.InetSocketAddress;
import java.io.IOException;
/**

public class ElastiCache {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        // TODO code application logic here

        try {
        //127.0.0.1 - machine's ip
        //11211 - port in which memcache server running

        MemcachedClient c = new MemcachedClient(new InetSocketAddress("cachetest.7hpjru.cfg.use1.cache.amazonaws.com", 11211));
        ///MemcachedClient c = new MemcachedClient(new InetSocketAddress("cachetest.7hpjru.0001.use1.cache.amazonaws.com", 11211));

        String s = "ElastiCache";
        c.set("someKey", 3600, s);

        Object myObject = c.get("someKey");
        System.out.println("\n myobject---->" + myObject.toString());
        //c.delete("someKey");

    } catch (IOException ex) {
        ex.printStackTrace();
    }

    }

}
