2. Objectives
* ︎The main objective of the project “PANACEA” is to provide
Proactive Autonomic Management of Cloud Resources
* Autonomic Cloud architecture based on IBM’s architecture for
autonomic computing
* Self-awareness, to allow VMs to know their execution
environment
* Self-configuration, to allow VMs to request changes at runtime

4. OpenNebula-based Autonomic
Cloud Architecture
* OpenNebula is the Cloud Manager, supporting several
reconfiguration operations on VMs
* OneFlow is the Service Manager, supporting service auto-scaling
* OneGate is a HTTP server with a REST interface providing self-monitoring
to VMs, allowing them to push application-level
monitoring metrics (PUT action)
* It is being extended to provide self-awareness (GET action) and
self-configuration (POST action)
