The document discusses integrating the btrCloud solution into the CloudStack infrastructure. It describes btrCloud as a software developed by ASCOLA to manage and optimize virtualized data centers. BtrCloud includes low-level stacks like BtrMonitor that collects metrics and BtrAction that manages lifecycles, and medium-level stacks like BtrScript for infrastructure management and BtrReport for consumption reporting. Integrating btrCloud would allow CloudStack to meet QoS requirements like setting affinity rules and optimizing migrations.

btrCloud: low level stacks
6/10/13 CloudStack – btrCloud.org4
●
BtrMonitor:
→ connect to Hypervisor, Iass ...
→ get model introspection
→ manage the metrics flow
●
BtrAction:
→ manage the Host & VM's lifecycle
create, start, stop, destroy, migrate ...

btrCloud: medium stacks
6/10/13 CloudStack – btrCloud.org5
●
BtrScript:
→ specific language to manage a large-scaled infrastructure
→ perform actions on a vm / vm group
→ placement rules management
→ optimization module (power algo ...)
●
BtrReport:
→ consumption reporting
→ vm behavior identification (idle, lazy, ghost …)
→ vm resources usage (busy, undersized ...)
