Outline and Presentation Objective

Provide common terminology for discussion
• What is Hybrid meaning in OpenStack scope?
• How to bridge two “worlds”

The Major User Cases benefit from the hybrid model
• Extend your workload for extra resource in demand (Auto Scale)
• Recover your OpenStack workload in another cloud (DR)
• Specific usage cloud (storage cloud and computing cloud)

Current Effort on Hybrid
• An Method of hybrid prototype
• Where we are
• The challenge of making hybrid happen

What is Hybrid

Hybrid is to connect public cloud, private cloud to fit the business requirements
• Public cloud for pay-as-you-go and auto-scale
• Private cloud for enhanced security, performance, reliability and ultimate control

Bridge Clouds with Regions


4
Bridge two clouds with two regions
• The same shared service (Keystone)
• Multiple regions and each region may cover one rack of servers
Targeted for resource consolidation in the same data center
• Multiple virtualization hypervisor, and bare metal

Bridge Clouds with Federation (Distributed Cloud)

Bridge Two OpenStack Clouds
• Nothing shared, and two clouds operated independent perfectly
• Federated Keystone
• Identity service using external identity providers
Targeted for OpenStack hybrid with OpenStack
• Primary OpenStack cloud and secondary OpenStack cloud in the same enterprise
• Private and public OpenStack cloud

Bridge Cloud with the “Wild” Hybrid

6
Bridged OpenStack Cloud with cloud having different architecture
• OpenStack with Amazon (not through OpenStack EC2 APIs)
• OpenStack with whatever cloud (completely different architecture)
Targeted for OpenStack hybrid with Non-OpenStack
• The resource from the other cloud is viewed/operated as another OpenStack region
• The user applications built upon OpenStack APIs don’t need to change
• Resource consolidated across multiple cloud vendors
• More flexibility to choose cloud resource vendors

How to Leverage Hybrid Cloud Model – Use Case 1

7
Meet temporary capacity needs that can not be met by the private cloud
• Service capability automatically expanded according to the workload
• An application runs in a private cloud or data center and "bursts" to a public cloud when
the demand for computing capacity increases
• An organization only pays for extra compute resources when they are needed

How to leverage hybrid cloud – Use Case II

8
Disaster Recovery and Backup
• Buy extra resource in public cloud to prepare the worst time
• Replicate the operation/metadata did from private to public
• Content (volume, VM, images) is replicated according to service agreement
• Recovered to private cloud after private service recovered

How to leverage hybrid cloud – Use Case III

9
Special usage cloud (Storage cloud, and Computing cloud)
• Organization stores sensitive client data in house on a private cloud application
• Interconnect that application to a billing application provided on a public cloud as a
software service
• Use the computing capability in Public cloud as pay-as-you go

Hybrid OpenStack Cloud Implementation I
Create another OpenStack cloud in the
targeted OpenStack/Non-OpenStack cloud
• TripleO: create OpenStack on top of
OpenStack for OpenStack based cloud
• Deployer: Major four steps
Step 1: Bare Metal provision
Step 2: Deploy with specific topology
Step 3: Configure the cloud
Step 4: minimum set of tests to ensure
the cloud is working

Hybrid Framework for
Two Clouds
• A framework to
accept requests
from applications
• A plugin to translate
the requests to
another cloud APIs

Challenge of Hybrid Implementation


What has been done
• Federation in keystone
• Multi-region in OpenStack
What needs to be done (need help from community)
• Workload is not able to cross hybrid clouds
• Heat across multi-region
• Volume replicated cross hybrid clouds
• Big layer 2 switch with isolation and security
• Bare metal provisioning
• Glance repository to cross the hybrid cloud
• Different formats of images
• Require the image repository to have the same images
• Swift across private and public
