So, you’ve got your solution deployed and have so many things to manage…now what? Come to this session to learn how you can scale operations with solutions deployed in the AWS cloud. We take a look at services like AWS CloudFormation and tools like Chef and Puppet. See an overview of these services and tools, and we show you how they might be used in real-life scenarios and how you might incorporate these services and tools into your own environment.

30. Parameters:

31. Mappings:

32. Resources – EC2:

33. Resources – Streaming Media Server:

34. Resources – CloudFront Distribution:

35. Outputs:

37. Resources – RDS:

38. Resources – Security Groups:

39. Resources – VPC:

41. Use AWS::CloudFormation::Init with cfn-init to help bootstrap instances:

42. Install packages with the native package management tool:

56. That sounds a lot like
CloudFormation?

58. Together, a great solution

61. CloudFormation: Chef / Puppet:

62. So what does working
with this all look like?

66. automatically setting up your
servers
 Install latest software  Copy data  Open port 80
 Register with DNS  Update packages  Mount devices
 Start services  Reboot

67. automatically setting up
your servers

68. automatically setting up
your servers

69. Fully Functional AMI OS-Only AMI
Partially Configured
AMI

70. CloudFormation - Install Packages needed to run Chef:

71. CloudFormation – Configure files needed to run
Chef:

72. CloudFormation – Configure node role:

73. CloudFormation – Have UserData run Chef at start:
"Properties”:
…
