Hybrid Clouds… What?Two or more clouds, having the following characteristics:a. Usually a public cloud paired with a private cloud deploymentb. Enabling “cloud bursting” scenarios and use casesc. “Own the core, rent the spikes”d. Applications tied to capabilities/services of the cloud providerVertical hybrid products, a single vendor provides both clouds
Hybrid Clouds… Wouldn’t It Be Nice?Java: “Write Once (in Java), Run Everywhere”True Hybrid Clouds: “Write Once (in any language and runtime), Run Everywhere (in the Cloud)”Easily scale applications to meet the demand loadHave true workload portability across the CloudHorizontal Hybrid products, seamless integration of multiple Cloud providers
Hybrid Clouds… Use Cases• Build (dev/test) and deploy (production) applications efficiently & economically• Traditional Cloud “bursting”• Data Center Consolidation• Allowing insight, control, and governance over “shadow IT”• High Availability and Redundancy of Applications• Disaster Recovery and Business Continuity• Business dictates cloud topology & usage
Aspirations of Workload Portability Governance/Proposed/ImageFormats Time: 2011-01-14 16:40:23 Drafter: John Purrier Status: Proposed to the POC Image Formats and workload portability in OpenStack. OVF as the standard VM Disk Image exchange format No “preferred” or “default” virtual disk format Glance extended to provide cross-cloud exchange & virtual appliance conversion capabilities.
Great Strides• Quantum Software Defined Network project• Keystone Identity & Authorization projectBuilding blocks to true federation across clouds.However, no current solution for workload portabilityacross heterogeneous clouds.• Different hypervisors• Different physical topologies (# NICs, etc.)• Different levels of API compatibility• Different types of service deployments
Extending OpenStack with Cloud Foundry• Open “Platform as a Service” project• Open Source, Apache 2.0 License• Freely Available on GitHub (https://github.com/cloudfoundry)Provides an Infrastructure neutral application runtimeenvironment.The Cloud Foundry API provides a defacto-standard PaaS API.This API can even be layered over other PaaS clouds to provideseamless access and workload motion. For instance the workAppFog & Microsoft have done to integrate Azure.
Cloud Foundry Design • Fail Fast & Self Healing • Horizontally Scaling Components • Loosely coupled, distributed state • No single point of failure • HA as a design point • Eventually consistent system
