Open source software

Strategic elimination of vendor lock­in OSS naturally creates multiple vendors

Cost reduction in multiple dimensionsHardware; system administration; compute transactions/watt; license management  

Improved security Proven security through better technology & threat response record

AuditabilityCustomers and industry can verify standards adherence, quality & flexibility

TechnologyAll leading software technology development today is being done under the OSS model

Performance , Maturity , Choice More suppliers than any proprietary offering = more improvements, more testing, greater selection

Solution Ecosystem OEM and ISV suppliers across the IT industry are focusing on delivering OSS solutions

Allows developers worldwide to collaborate and benefit.

Virtualization

● Product features are subject to change prior to final product availability.

  Security                 Agility                Reduced CostSecurity                 Agility                Reduced Cost

Multiplex one machine into different  “Virtual Machines” VMs

Allows a “Guest” OS to run 

    under control of a supervising 

    master program that is called:

            “Hypervisor”  or 

            “Virtual Machine Monitor (VMM)”. 

Hypervisor / VMM Functionality:● Virtualizes System Resources● Provides Scheduling of host/guests● Intra­guest communication 

Hypervisor/VMM

Hardware

What is Virtualization?

The Leading Hypervisor Technology, Developed by the Open Source Community working with XenSource.

Almost native OS Performance Separate the Server Hardware     from the Server Software resulting a     guest Operating Systems that:

● Completely and Securely Isolated● Allows different workload to co­exist on same physical 

hardware sharing resources safely Improved Enterprise Agility: Ability to migrate guests (in less than 

100ms) from one environment to another in response to demand. Guests can be cloned to add redundancy or capacity without 

adding cost or managing complexity

Domain 0 – Privileged Domain,the host. Provides hardware support (backend drivers) interfaces for guests control and    management tools

Xen Hypervisor provides IRQ routing, Scheduling , and inter­domains communications. The Hypervisor with the Dom0 Device Drivers provide transparent sharing of resources. It also enforces strict resource limitations (example: RAM). 

Based on Xen Technology. Given the 

     current level of performance and maturity, 

     Xen is the undisputed leader in 

     open­source virtualization. Operating System Integration yields     significantly better performance. libvirt – local Virtual Machine (VM)    management API that enables     management and monitoring integration

Red Hat Virtualization: Roadmap

Some things are worth remembering...

Xen is a paravirtualizing hypervisor system● High performance, but needs a modified OS kernel

Can do full virtualization with hardware support Common use cases: consolidation, security, management, testing Advanced features: memory ballooning, live migration Xen is still in development

● X86­64, IA64, PPC64 still in flux Xen is a technology to watch, it should be enterprise ready “soon” Xen is in Fedora Core 5
