3. APIs Hurt
4. 1. Search for existing, often shoddy library
5. 2. DIY Wrapper
6. 3. New vendor comes along that does your laundry too!
7. 4. Sad face :(

9. Cross Service Compatibility
10. gem install fog
11. require 'fog'
12. Cloud Storage
13. s3 = Fog::Storage.new( provider: "AWS", aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) gg = Fog::Storage.new( provider: "Google", google_storage_access_key_id: "KEY", google_storage_secret_access_key: "SECRET" ) rs = Fog::Storage.new( provider: "Rackspace", rackspace_api_key: "KEY", rackspace_auth_url: "URL", rackspace_username: "USERNAME" ) s3.put_object(bucket_name, object_name, data, options = {}) gg.put_object(bucket_name, object_name, data, options = {}) rs.put_object(container, object_name, data, options = {})
14. s3.put_object(bucket_name, object_name, data, options = {}) gg.put_object(bucket_name, object_name, data, options = {}) rs.put_object(container, object_name, data, options = {}) Consistency Provider Flexibility
15. Cloud Servers
16. ec2 = Fog::Compute.new( provider: "AWS", aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) rsc = Fog::Compute.new( provider: "Rackspace", rackspace_api_key: "KEY", rackspace_username: "SECRET" ) ec2.servers.create( flavor_id: "c1.medium", image_id: "ami-6936fb00", # Ubuntu 10.04 LTS key_name: "mykeyname", groups: ["default"], ) rsc.servers.create( flavor_id: 5, # 4GB Memory image_id: 49, # Ubuntu 10.04 LTS name: 'my_server_name' )
17. DNS
18. z = Fog::DNS::Zerigo.new( zerigo_email: "email", zerigo_token: "secret", scheme: "https", port: 443 ) zone_id = z.create_zone("bensie.com", 14400, "pri_sec") .body["id"] z.create_host(zone_id, "CNAME", "ghs.google.com", hostname: "mail", ttl: 14400 )
19. AWS Management Console RS Cloud Control Panel • Multi-step wizards • Missing features • Slow • One account at a time
20. AWS Management Console
21. rds = Fog::AWS::RDS.new( aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) rds.create_db_instance("my-db-instance" "AllocatedStorage" => 50, "AutoMinorVersionUpgrade" => false, "BackupRetentionPeriod" => 3, "DBInstanceClass" => "db.m1.large", "DBParameterGroupName" => "utf8", "Engine" => "mysql", "EngineVersion" => "5.5.12", "MasterUsername" => "username", "MasterUserPassword" => "password", "MultiAZ" => true )
22. rds = Fog::AWS::RDS.new( aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) rds.create_db_parameter_group( "utf8", "mysql5.5", "utf8" ) rds.modify_db_parameter_group("utf8", [ { "ParameterName" => "character_set_server", "ParameterValue" => "utf8", "ApplyMethod" => "immediate" }, { "ParameterName" => "collation_server", "ParameterValue" => "utf8_general_ci", "ApplyMethod" => "immediate" } ] )
23. elb = Fog::AWS::ELB.new( aws_access_key_id: "KEY", aws_secret_access_key: "SECRET" ) load_balancers = elb.describe_load_balancers .body["DescribeLoadBalancersResult"] ["LoadBalancerDescriptions"] load_balancers.each do |lb| elb.register_instances_with_load_balancer( ["i-3dcba453", "i-37cba459"], lb["LoadBalancerName"] ) end
