Creating a cluster for Memcached - Amazon ElastiCache

Creating a cluster for Memcached

The following examples show how to create a cluster using the AWS Management Console, AWS CLI and ElastiCache API.

When you use the Memcached engine, Amazon ElastiCache supports horizontally partitioning your data over multiple nodes. Memcached enables auto discovery so you don't need to keep track of the endpoints for each node. Memcached tracks each node's endpoint, updating the endpoint list as nodes are added and removed. All your application needs to interact with the cluster is the configuration endpoint.

To create a Memcached cluster, follow the steps at Create a cluster

As soon as your cluster's status is available, you can grant Amazon EC2 access to it, connect to it, and begin using it. For more information, see Step 3. Authorize access to the cluster and Step 4. Connect to the cluster's node.

Important

As soon as your cluster becomes available, you're billed for each hour or partial hour that the cluster is active, even if you're not actively using it. To stop incurring charges for this cluster, you must delete it. See Deleting a cluster in ElastiCache.

To create a cluster using the AWS CLI, use the create-cache-cluster command.

Creating a Memcached Cache Cluster (AWS CLI)

The following CLI code creates a Memcached cache cluster with 3 nodes.

For Linux, macOS, or Unix:

aws elasticache create-cache-cluster \
--cache-cluster-id my-cluster \
--cache-node-type cache.r4.large \
--engine memcached \
--engine-version 1.4.24 \
--cache-parameter-group default.memcached1.4 \
--num-cache-nodes 3

For Windows:

aws elasticache create-cache-cluster ^
--cache-cluster-id my-cluster ^
--cache-node-type cache.r4.large ^
--engine memcached ^
--engine-version 1.4.24 ^
--cache-parameter-group default.memcached1.4 ^
--num-cache-nodes 3

To create a cluster using the ElastiCache API, use the CreateCacheCluster action.
