Serverless Stack

Hello , can anyone help me with example , how to use DAX in serverless application ?

Hey <@U025L60JNA0>, I don’t have a code snippet to share at the moment, but you’d need to create a VPC and a DAX cluster in CDK.

This is an example of creating a DAX cluster using raw CloudFormation <https://github.com/aws-samples/amazon-dax-lambda-nodejs-sample/blob/master/template.yaml#L49-L139>

These are the AWS resources you need to create:
```AWS::DAX::Cluster
AWS::DAX::SubnetGroup
AWS::IAM::Role
AWS::EC2::SecurityGroup
AWS::EC2::SecurityGroupIngress
AWS::EC2::VPC
AWS::EC2::Subnet```

And you use:
• `aws-dax.CfnCluster` to create the `AWS::DAX::Cluster` (<https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-dax.CfnCluster.html|doc>)
• `aws-dax.CfnSubnetGroup` to create the `AWS::DAX::SubnetGroup` (<https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-dax.CfnSubnetGroup.html|doc>)
• `aws-iam.Role` to create the `AWS::IAM::Role` (<https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-iam.Role.html|doc>)
• `aws-ec2.Vpc` to create the `AWS::EC2::*` (<https://docs.aws.amazon.com/cdk/api/latest/docs/@aws-cdk_aws-ec2.Vpc.html|doc>)

Give it a try and let me know if it works for you!

^ note that you’d need to deploy your Lambda functions inside the VPC to talk to DAX.
