Delivery Lead @ Angie’s List

Came up with a Continuous Delivery platform and refrecne implementation to provide a complete working Continuous Delivery solution using industry-standard open source tools such as Jenkins, Puppet, Chef, Capistrano, Ruby, Maven, git, Java, etc. Uses the following tools

CloudFormation – CloudFormation is a domain-specific language expressed in JSON for automating the provisioning/management of AWS resources. These CloudFormation scripts automate the provisioning of AWS resources (IAM, EC2, S3, Route 53, SNS, RDS, ELB and Auto Scaling) and make calls to Puppet scripts that execute the rest (provisioning/configuration of servers on the instances)
IAM – IAM is the user authentication and authorization service for AWS. The Delivery Scripts provisions IAM users for secure access to AWS resources in its CloudFormation scripts.
EC2 – (Security Groups, KeyPairs) EC2 is the service for launching compute instances in AWS and automatically provisions EC2 instances based on AMIs. Italso configures security groups as part of virtual firewall configuration.
S3 – It has CloudFormation scripts that push files, create keys, etc. in S3.
Route 53 – Route53 is an automated DNS. From CloudFormation, it configures Route 53 to allocate domain names.
Simple Notification Service (SNS) – In CloudFormation, it configures SNS to send notification messages to inform users and services based on events.
RDS – In CloudFormation, configures RDS
Elastic Load Balancer – In CloudFormation, provisions ELB to distribute traffic across multiple Amazon EC2 instances, as necessary.
Auto Scaling – In CloudFormation, provisions launch configurations and Auto Scaling groups to provide support for scaling instances across AZs
Github – uses Github for version control
Jenkins – automates the provisioning and configuration for all of the Jenkins Continuous Integration Server including plugins, jobs, server configuration, etc.
Puppet – Puppet scripts are called by CloudFormation. It’s Puppet scripts automate the provisioning and configuration of servers on the EC2 instances. These include, but are not limited to, Java, Ruby, GCC, Tomcat, MySQL and PostgreSQL.
Chef – Chef It is in the process of supporting Chef.
Cucumber – Cucumber is a behavior-driven framework written in Ruby. It calls Cucumber scripts from Jenkins to test the infrastructure and deployment to ensure they were successful or, otherwise, notify team members.
Capistrano – Capistrano is a deployment framework written in Ruby. It calls Capistrano scripts from Jenkins to perform
Ruby – uses Ruby as the “glue” between all of its components. These Ruby scripts run tests, delete stacks and instances, etc.
Dev Platforms – It provides “out-of-the-box” automation for Rails, Java and Grails on the Linux operating system. Other platforms can be supported by OpenDelivery. and, provides analogous automation for MySQL, PostgreSQL, Tomcat and Apache.
