6. CloudWatch Event scheduler to trigger Lambda function to publish data to SiteWise;
7. Relevant IAM policies and roles that permit the Lambda functions to do the following: (1) Access SiteWise to create assets/assets models, and alarm models; (2) Update SiteWise asset property values with BatchPutMessage operation; 
8. Permission to allow CloudWatch Event to trigger Lambda function to batch put asset property values;
9. CloudWatch Log Group for monitoring individual Lambda function.
