Amazon Elastic Compute Cloud (Amazon EC2) provides resizable compute capacity in the cloud and is often the starting point for your first week using AWS. This session will introduce these concepts, along with the fundamentals of EC2, by employing an agile approach that is made possible by the cloud. Attendees will experience the reality of what a first week on EC2 looks like from the perspective of someone deploying an actual application on EC2. You will follow them as they progress from deploying their entire application from an EC2 AMI on day 1 to more advanced features and patterns available in EC2 by day 5. Throughout the process we will identify cloud best practices that can be applied to your first week on EC2 and beyond.

- 37. Resources created programmatically Configure automatically
- 38. Bake an AMI Start an instance Configure the instance Create an AMI from your instance Start new ones from the AMI Bootstrapping

- 40. Bake an AMI Configure dynamically Start an instance Configure the instance Create an AMI from your instance Start new ones from the AMI Bootstrapping Launch an instance Use metadata service and cloud-init to perform actions on instance when it launches vs Bootstrapping
- 41. Bake an AMI Build your base images and setup custom initialisation scripts Maintain your ‘golden’ base Bootstrapping Use bootstrapping to pass custom information in and perform post launch tasks like pulling code from SVN + Bootstrapping Configure dynamically
- 42. Bake an AMI Bootstrapping Time consuming configuration (e.g startup time) Static configurations (e.g less change management) Bootstrapping Configure dynamically
- 43. Bake an AMI Bootstrapping Continuous deployment (e.g latest code) Environment specific (e.g dev-test-prod) Bootstrapping Configure dynamically
- 44. Goal is bring an instance up in a useful state The balance will vary depending upon your application
