Provider The type, brand, or flavor of virtualenvironment. Ex: RHEV, VMware,OpenStack, etc. 8. HHiissttoorryyFirst released in 2007 Initially supported: Windows: NTFS, Fat32 Linux: LVM2, EXT3 Extended to support: Windows: LDM Linux: EXT4, XFS 9. DDeessiiggnn CCoonnssiiddeerraattiioonnss aannddRReeqquuiirreemmeennttssFlexible virtual disk access Access provided through extensible mechanism. Optimize access method for given providers. Supports provider-specific API access Eliminates the need for file-level access. Enables remote fleecing. Affords greater flexibility in appliance placement. Proximity to storage need not be a factor. 10. DDeessiiggnn CCoonnssiiddeerraattiioonnss aannddRReeqquuiirreemmeennttssLightweight Each fleece is performed in a single Ruby thread. Consumes a minimum of appliance resources. Imposes minimum impact on other appliance processes. Enables parallel fleecing of multiple VMs on the sameappliance. Affords more flexibility in proxy deployment. 11. DDeessiiggnn CCoonnssiiddeerraattiioonnss aannddRReeqquuiirreemmeennttssMinimal Dependancies Only requires Ruby and requisite provider libraries. Does not encumber appliance configuration withadditional dependancies. Enables the creation of self-contained proxyexecutables. Facilitates the deployment of proxies to foreignenvironments. 12.

Can run in Windows and Linux environments. Facilitates the development of proxies fordeployment to foreign environments. 13.
