To deploy this application, you need to have configured the AWS CLI tool and a user with the following permissions:

• AWSLambdaFullAccess
• IAMFullAccess
• AmazonDynamoDBFullAccess
• AmazonAPIGatewayAdministrator
• AmazonCognitoPowerUser
• CloudFormationAdministrator

It is worth noting that the latter was created manually and can be added when configuring the user by adding a JSON definition to the policy:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Sid": "Stmt1449904348000",
            "Effect": "Allow",
            "Action": [
                "cloudformation:CreateStack",
                "cloudformation:CreateChangeSet",
                "cloudformation:ListStacks",
                "cloudformation:UpdateStack",
                "cloudformation:DeleteStack",
                "cloudformation:DescribeStacks",
                "cloudformation:DescribeStackResource",
                "cloudformation:DescribeStackEvents",
                "cloudformation:ValidateTemplate",
                "cloudformation:DescribeChangeSet",
                "cloudformation:ExecuteChangeSet"
            ],
            "Resource": [
                "*"
            ]
        }
    ]
}

When you have created a user with the necessary credentials, you can build and deploy the application using the Serverless Framework, which builds all the lambdas automatically.
