  2. Utilize Amazon ElastiCache Serverless for Redis and Memcached

How do I utilize Amazon ElastiCache Serverless for Redis and Memcached?

In this guide, we will set up Amazon ElastiCache Serverless for Redis and Memcached using Pulumi in TypeScript. We will define and provision the necessary resources, including the ElastiCache clusters for both Redis and Memcached, along with their configurations.

Steps to Set Up Amazon ElastiCache Serverless for Redis and Memcached

  1. Install Pulumi and AWS SDK: Ensure you have Pulumi and AWS SDK installed and configured.
  2. Define the ElastiCache Clusters: Create Redis and Memcached clusters with the required configurations.
  3. Provision the Resources: Use Pulumi to deploy the infrastructure to AWS.

Below is the complete Pulumi program in TypeScript to accomplish this:

import * as pulumi from "@pulumi/pulumi";
import * as aws from "@pulumi/aws";

// Define a VPC
const vpc = new aws.ec2.Vpc("myVpc", {
    cidrBlock: "10.0.0.0/16",
});

// Define a Subnet
const subnet = new aws.ec2.Subnet("mySubnet", {
    vpcId: vpc.id,
    cidrBlock: "10.0.1.0/24",
    availabilityZone: "us-west-2a",
});

// Define a Security Group
const securityGroup = new aws.ec2.SecurityGroup("mySecurityGroup", {
    vpcId: vpc.id,
    ingress: [
        { protocol: "tcp", fromPort: 6379, toPort: 6379, cidrBlocks: ["0.0.0.0/0"] }, // Redis
        { protocol: "tcp", fromPort: 11211, toPort: 11211, cidrBlocks: ["0.0.0.0/0"] }, // Memcached
    ],
    egress: [{ protocol: "tcp", fromPort: 0, toPort: 0, cidrBlocks: ["0.0.0.0/0"] }],
});

// Define ElastiCache Redis Cluster
const redisCluster = new aws.elasticache.Cluster("myRedisCluster", {
    engine: "redis",
    nodeType: "cache.t3.micro",
    numCacheNodes: 1,
    parameterGroupName: "default.redis6.x",
    port: 6379,
    subnetGroupName: new aws.elasticache.SubnetGroup("redisSubnetGroup", {
        subnetIds: [subnet.id],
    }).id,
    securityGroupIds: [securityGroup.id],
});

// Define ElastiCache Memcached Cluster
const memcachedCluster = new aws.elasticache.Cluster("myMemcachedCluster", {
    engine: "memcached",
    nodeType: "cache.t3.micro",
    numCacheNodes: 1,
    port: 11211,
    subnetGroupName: new aws.elasticache.SubnetGroup("memcachedSubnetGroup", {
        subnetIds: [subnet.id],
    }).id,
    securityGroupIds: [securityGroup.id],
});

// Export the endpoints of the clusters
export const redisEndpoint = redisCluster.cacheNodes.apply(nodes => nodes[0].address);
export const memcachedEndpoint = memcachedCluster.cacheNodes.apply(nodes => nodes[0].address);

Key Points

  • VPC and Subnet: We created a VPC and a Subnet to host our ElastiCache clusters.
  • Security Group: We defined a security group to allow traffic to Redis (port 6379) and Memcached (port 11211).
  • ElastiCache Clusters: We set up both Redis and Memcached clusters with the necessary configurations.
  • Endpoints: The endpoints of the clusters are exported for use in applications.

Summary

In this guide, we set up Amazon ElastiCache Serverless for Redis and Memcached using Pulumi in TypeScript. We defined and provisioned a VPC, Subnet, Security Group, and the ElastiCache clusters, and exported the endpoints for use in applications. This setup provides a scalable and managed caching solution on AWS.
