Get Started with AmazonElastiCache

Amazon ElastiCache is a web service that makes it easy to set up, manage, and scale distributedin-memory cache environments in the cloud. It provides a high performance, resizeable, and cost-effectivein-memory cache, while removing the complexity associated with deploying and managing a distributedcache environment. Amazon ElastiCache is protocol-compliant with Memcached, so the code, applications,and most popular tools that you use today with your existing Memcached environments will work seamlesslywith the service.

Note

For more information about Memcached, go to http://memcached.org.

This guide walks you through creating and connecting to your first Amazon ElastiCache Cache Cluster.



http://memcached.org/

Sign Up for Amazon ElastiCache

To use Amazon ElastiCache, you need an AWS account. If you don't already have one, you'll be promptedto create one when you sign up for Amazon ElastiCache.

To sign up for Amazon ElastiCache

1. Go to http://aws.amazon.com/elasticache and click Sign Up for Amazon ElastiCache.

2. Follow the on-screen instructions.

Once you've signed up for Amazon ElastiCache, you'll be able to launch your own Cache Cluster.Jump to Create a Cache Cluster (p. 3).



http://aws.amazon.com/elasticache

Create a Cache Cluster

Now that you have signed up for Amazon ElastiCache, you're ready to create a Cache Cluster using theAWS Management Console.

Important

The Cache Cluster you're about to launch will be live (and not running in a sandbox).You willincur the standard Amazon ElastiCache usage fees for the instance until you delete it. The totalcharges will be minimal (typically less than a dollar) if you complete the exercise described herein one sitting and delete your Cache Cluster when you are finished. For more information aboutAmazon ElastiCache usage rates, go to the Amazon ElastiCache product page.

To launch a Cache Cluster

1. Start the launch wizard:

a. From the AWS Management Console page, select Amazon ElastiCache from the drop-downlist box, then click Sign in to the AWS Console and log in with the email address and passwordyou used when signing up for Amazon ElastiCache.

Tip

If you pause for a long period of time during this procedure, the AWS ManagementConsole automatically logs you out.To stay logged in while you work through this tutorial,click Settings in the top right corner of the console window and clear the Sign out oninactivity check box.



http://aws.amazon.com/elasticache

http://aws.amazon.com/console

b. From the Amazon ElastiCache Console Dashboard, click Launch Cache Cluster to start theLaunch Cache Cluster Wizard.

The wizard opens on the Cache Cluster Details page.

2. Specify the name of your Cache Cluster by typing it into the Name text box.

3. Select the amount of memory you want for each Cache Node in your Cache Cluster by selecting aNode Type from the Node Type drop-down list box.

4. Select the number of Cache Nodes you want in your Cache Cluster by typing a number into theNumber of Nodes text box.

5. You can change the default port that your Cache Nodes will use to accept connections by typing itinto the Cache Port text box.

6. Leave the rest of the options on the Cache Cluster Details page at their default values, and clickthe Continue button.

7. After you click the Continue button, the Additional Configuration page opens.



8. The Additional Configuration page is where you can specify a Cache Security Group, CacheParameter Group, and Maintenance Window for you Cache Cluster. For this example, accept thedefault values, and then click the Continue button.

After you click the Continue button, the Review panel appears.

9. Review the options for your Cache Cluster:

• If you need to correct any options, click the Back button to return to previous panels and makecorrections.

• If all your options are entered correctly, click the Launch button to launch your new Cache Cluster.

After you click the Launch button, a message displays stating that your Cache Cluster is beingcreated.

This can take a few minutes to complete.



10. Click the Close button.

After you click the Close button, the My Cache Clusters panel appears.Your Cache Cluster appearsin the list on this page with the creating status until your Cache Cluster is created and ready for use.

Once your Cache Cluster changes to the available state, you need to authorize access so you canconnect to it. Jump to Authorize Access (p. 7).



Authorize Access

Now that you've created a Cache Cluster, you need to authorize access to the Cache Cluster.You dothis by granting an EC2 Security Group access to a Cache Security Group. The EC2 Security Groupgrants access to Amazon EC2 instances, and in turn the Cache Security Group grants access to theAmazon EC2 instances that are authorized for the EC2 Security Group.

Granting Access to the Cache ClusterIn this example, you authorize the default Cache Security Group.

To grant access to an EC2 Security Group for a Cache Security Group

1. Select Cache Security Groups from the navigation pane on the left side of the console window.

2. In the My Cache Security Groups list, select the check box next to the Cache Security Group nameddefault.


Amazon ElastiCache Getting Started GuideGranting Access to the Cache Cluster

3. On the detail panel at the bottom of the window:

a. Type the name of the EC2 Security Group you wish to authorize into the EC2 Security Groupto Link text box.

b. Enter your AWS Account ID into the AWS Account Id text box.

Note

You can find your AWS Account ID in the upper right corner of the Security Credentialspage.

c. Click the Add button.

It takes approximately one minute for changes to access permissions to take effect.Your CacheSecurity Group will show a status of Authorizing next to the EC2 Security Group while theauthorization is in progress.

Now that you've authorized access to your Cache Cluster, you can connect to it. Jump to Connectto a Cache Node (p. 9).

Connect to a Cache Node

Important

This section assumes that you've created an Amazon EC2 instance and can connect to it. Forinstructions on how to do this, please go to the Amazon EC2 Getting Started Guide.

Once you've authorized access to the Cache Cluster using the AWS Management Console and yourCache Cluster is in the available state, you can connect to a Cache Node in the Cache Cluster.

Important

You can only connect to a Cache Node from an EC2 Instance that belongs to the EC2 SecurityGroup that you authorized in the Authorize Access (p. 7) section.

In the following example, you use the telnet utility to connect to the Cache Cluster you just created.

Note

For more information about Memcached and available Memcached commands, go tohttp://memcached.org.

To connect to a Cache Cluster using telnet

1. Find the endpoint of the Cache Node you want to connect to.

a. On the My Cache Clusters page of the AWS management Console, click the name of a CacheCluster.

The detail page for the Cache Cluster appears.

b. Click the Nodes tab at the top of the window.

c. On the Nodes tab of the detail window, note the endpoint of a Cache Cluster to use in the nextstep.



http://docs.amazonwebservices.com/AWSEC2/latest/GettingStartedGuide/

http://memcached.org/

Note

The endpoint for your Cache Cluster isn't available until your Cache Cluster is in theavailable state.

2. Connect to your Amazon EC2 instance using the connection utility of your choice.

Note

For instructions on how to do this, please go to the Amazon EC2 Getting Started Guide.

3. On your EC2 instance, Open a command prompt and enter the following command; make sure touse the endpoint of the Cache Cluster you created.

PROMPT> telnet myfirstcacheinstance.evdfes.0001.use1.cache.amazonaws.com 11211

You will see output similar to the following.

Trying 128.0.0.1...Connected to myfirstcacheinstance.evdfes.0001.use1.cache.amazonaws.com.Escape character is '^]'.>

You are now connected to a Cache Node and may run Memcached commands. For example:

set a 0 0 5 // Set key “a” with no expiration and 5 byte valuehello // Set value as “hello”STOREDget a // Get value for key “a”VALUE a 0 5helloENDget b // Get value for key “b” results in cache missEND>



http://docs.amazonwebservices.com/AWSEC2/latest/GettingStartedGuide/

Once you're finished with your new Cache Cluster, make sure to delete it to avoid incurring further usagecharges. Jump to Delete Your Cache Cluster (p. 12).



Delete Your Cache Cluster

As soon as your Cache Cluster becomes available, you’re billed for each hour or partial hour that youkeep the Cache Cluster running (even if the Cache Cluster is idle). Once you've decided that you nolonger need the Cache Cluster, you can delete it.

To delete your Cache Cluster

1. In the AWS Management Console, locate the Cache Cluster in your list of Cache Clusters on theMy Cache Clusters page.

2. Click the Delete link next to the Cache Cluster.

The Delete Cache Cluster confirmation dialog box appears.

3. Click the Yes, Delete button.

Amazon ElastiCache begins deleting the instance. The Cache Cluster status changes to deletingin the My Cache Clusters list.



https://console.aws.amazon.com

As soon as the Cache Cluster status changes to deleted, you stop incurring charges for that CacheCluster.

Congratulations! You successfully launched, authorized access to, connected to, and deleted a CacheCluster. For more information about Amazon ElastiCache and how to continue, see Where Do I Go fromHere? (p. 14).
