Under the guidance of !Prof. Dinkar Sitaram,CSE!Prof. Phalachandra,CSE!
Centre for Cloud Computing and Big Data, PESIT!
Motivation and Background
• Explore Hybrid Cloud Federated Architectures.!• Design and Implement a mechanism for cloud
bursting and migrating for OpenStack.!• Contribute to the OpenStack community.
Objectives
• Bursting across different deployments.!• Workload Migration policies. !• Support for:!oScalability !oHigh Availability !
• Interface OpenStack with different clouds.!
• Design and implement decision-making algorithms for !• Moving Data To Compute!• Moving Compute To Data
High Level Architecture
Private Cloud Public Cloud
Nova Cells
A separate database and message broker per cell.!Inter-cell communication via pluggable driver. Eg:- RPC.!Top Cells consist of KeyStone, Glance, Nova-API, Nova-Cells and a Nova-Cells Scheduler.!Child Cells consist of Nova-Compute, Nova-Cells, Nova-Network.

Integration with Amazon
• Integration with Amazon Virtual Private Cloud!
• Ability to choose public/private IP Subnets for VM’s.!
• Compatibility with Hardware VPN.!
• Specify Custom Routing Tables/Firewall Rules.

Introduction of a Policy Manager - HEAT
• Orchestration Of Services Across Infrastructure.!
• Policy Manager for decision-making to burst/migrate.!
• Cloud Formation Templates Compatible!
• Support for AutoScaling.!!
HEAT with Cells
• Assume Cells as Availability Zones. !
• Use CloudFormation templates to scale across Cells.!
• Use simple Scheduler Hints to pick appropriate Child Cell.
OpenStack - OpenStack Bursting
Bursting across various Availability zones running OpenStack Cloud using the concept of OpenStack Cells.!Both the clouds are running on OpenStack using cells. ! The third party OpenStack child cell is attached as the child cell of the native OpenStack parent cell. ! Federation Strategies using KeyStone for added security.
Future Improvements
• Integration with Grizzly keystone!• Integration with Quantum!•Openstack to Openstack bursting!•Migrate and Burst
