Puppet is IT automation software that helps system administrators manage infrastructure throughout its lifecycle, from provisioning and configuration to patch management and compliance.

Behind the scenes

AWS CloudFormation gives developers and systems administrators an easy way to create and manage a collection of related AWS resources.

Once deployed, you can modify and update the AWS resources in a

controlled and predictable way allowing you to version control your AWS infrastructure in the same way as you version control your software

Cloud Formation Template…… "Resources" : { "Ec2Instance" : { "Type" : "AWS::EC2::Instance", "Properties" : { "InstanceType" : "c1.medium", "SecurityGroups" : [ { "Ref" : "InstanceSecurityGroup" } ], "KeyName" : { "Ref" : "KeyName" }, "ImageId" : { "Fn::FindInMap" : [ "RegionMap", { "Ref" : "AWS::Region" }, "AMI" ]}, "UserData": { "Ref": "BootScript" } } },……
