Why Hybrid Cloud?

• Provide resourcesina shorttimeframe• “buyingthebaseandrentingthepeak”• Fullgeographicreachneeded.

Hybrid Cloud UseCases

• BestCloud Allocation• Lifecycle-BasedDeployment• DisasterRecovery• Cloudbursting

security,latency,cost,andapplicationcomplexity.

BestCloud Allocation• Itinvolvesselectingthebestcloudfordeployingeachapplication.

• Theentireapplicationrunsinthatselectedprivateorpubliccloud.

Lifecycle-BasedDeployment• Dev/TestinPublicCloud,ProductioninPrivateCloud

• NewAppsinPublicCloud,Steady-StateAppsinPrivateCloud

DisasterRecovery• Usingpubliccloudfordisasterrecovery avoid thecostofprovisioningduplicate infrastructurethatisrarelyused.

• Greatlyreducingthetimerequiredtobringtheentireconfigurationtoanoperationalstate.

Cloudbursting

• Directconnection between cloud providers– AWSDirectConnect– Aliyun Express Connect

• Automationcapabilitiestohandleauto-scaling

Challenges• AccessControl:howtohandledifferentcredentialswithsecuritymanner?

• Multi-CloudManagement:howtomanagecloudswithasinglepane?

• Multi-Cloud Orchestration:howtoorchestrateapplicationsamong multi-cloud environment?

• Audit&Compliance:howtocollectauditdataandcomplywithregulations?

• NetworkConnectivity:howtomanagenetworkconfigurationsandmaintainconnectivityacrossclouds?

Summary

• The road to hybrid cloud with OpenStack isrough and steep.

• OpenStack itself lacks the capabilities to meethybrid cloud scenarios.

• The3rd platformcancentrallyleverageOpenStackAPIsto implement hybrid cloud.
