Challenges #1
• Multi-environment
• On-premise, hybrid, and legacy
• Bursting and spanning• Complex applications
• Custom dependency injection
• Richer applications

Need to update targets to match cluster
Need to publish MySQL URL for cluster
Need to specify autoscaling policy
There has to be a better way than scripting …

Concrete Entities
Abstract Entities
Managed Elements - AMP proxies for real world components
Autonomic Managers - AMP speci"c constructs or building blocks
Here we explicitly model the app’s organizational structure
MySQL and NGINX could be swapped out for their clustered variants

Policies Attached to entities they e!ect but can subscribe to any sensor
[targets] is a built in policy whereas the auto scaling policy is explicitly added
An application blueprint is completely portable

Challenges #2
• Usability — code is hard!
• Interop — #unicorns
25
© 2013 Cloudsoft Corporation
PUSH
26
• impose a common pattern on PaaSes
• Cloud4SOA !• Strong types in Brooklyn
• limited success (DI, locations, etc)
© 2013 Cloudsoft Corporation
PULL
27
• standards: create desire and make them achievable
• Oasis CAMP, TOSCA; OCCI• Cloud4SOA, SeaClouds (FP7)• OpenStack Heat, Cloudstack 576
• early days ... but huge momentum!
