I have summarized some of the follow-ups below as discussed: User Data and Meta Data – that can be used for bootstrapping as we discussed and I showed you a demonstration of - documentation: http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/AESDG-chapter-instancedata.html IP Addresses in VPC Auto Scaling Groups: Auto Scaling will automatically assign IP addresses using the DHCP provider when a new instance is launched. However, you could bootstrap it to assign additional IP addresses, using the Elastic Network Interface. Please be sure to consider the following too: http://docs.amazonwebservices.com/AWSEC2/latest/UserGuide/using-instance-addressing.html#MultipleIP Scaling Down Policies: For Auto Scaling Group policies, please use the following syntax when defining the scale down policy (notice how the negative adjustment value requires an "=" sign to work correctly: as-put-scaling-policy policy_scaledown1 --type ChangeInCapacity --auto-scaling-group koreaASG --adjustment=-1 --region ap-southeast-1 AWS Labs: Please download the AWS Labs that I showed you from the following location. It has step-by-step instructions for many scenarios and is a good way to get "your hands dirty" with the various services. It covers Auto Scaling as well as VPN connectivity to VPC using software-VPN. https://aws-labs.s3.amazonaws.com/latest/AWS%20Labs%20Workbook%20v2.2.zip?AWSAccessKeyId=AKIAI4BYU4OOGEEU5JZQ&Expires=1356896712&Signature=70P0jfBWqZkHy%2BO9hREOYJb5zWY%3D Custom Metrics: I have attached the step-by-step exercise we talked about for setting up custom metrics monitoring. These scripts are written in Perl, but you can use your own favorite language (I believe your preference is Java). For Java you can use the PutMetricDataRequest API. Custom metrics cost USD 0.50 per metric per month. Chef and CloudFormation: Please see below for the article on using CloudFormation with Chef configuration management: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CC8QFjAA&url=https%3A%2F%2Fs3.amazonaws.com%2Fcloudformation-examples%2FIntegratingAWSCloudFormationWithOpscodeChef.pdf&ei=GKqpUKGlEcbprQeY84GYAg&usg=AFQjCNE8MEewryO9PWVzBC5e086rEWYAwA&cad=rja Also see this link for a range of CloudFormation articles: http://aws.amazon.com/cloudformation/aws-cloudformation-articles-and-tutorials/ CloudFormation Services Not Supported: These are some of the services not supported by CloudFormation (at least not yet). You can see the up-to-date list of supported resources here. Not supported are: Elastic MapReduce, Amazon Fulfillment Web Services, CloudSearch, Simple Workflow Service, Simple Email Service, AWS Direct Connect, Flexible Payment Services, Simple Pay, DevPay, Glacier, Import/Export, Storage Gateway, Alexa, Mechanical Turk. I am still trying to confirm the roadmap for SWF global expansion and Provisioned IOPS. Thanks. Oyvind
