101 Virtualization and Private Cloud
- 2. Some Facts • About 7 Million Server are shipped every Year • 6 Million of them are x86 Intel Architecture • The number of transistors per square inch will double approximately every 18 months • Moore's law • VMware figured out how to virtualize the x86 platform • And created the market for x86 virtualization
- 4. Capacity Utilization • 20% of the servers assessed were running below 0.5% utilization • 75% of the assessed servers were running below 5% utilization
- 5. Mishap of Traditional Server Architecture • Underutilization of Servers • Datacenter Space • Energy Consumption • Increase in CO2 emissions • Management Complexity • Increasing IT Cost • IT Compliance issues
- 7. Virtualization Virtualization, in computing, is the creation of a virtual (rather than actual) version of something, such as a hardware platform, operating system, a storage device or network resources - From Wikipedia, the free encyclopedia
- 9. 9 Virtualization…for good reasons Server consolidation Energy efficiency Rapid IT service deployment Non-disruptive maintenance Dynamic resource balancing Cost-effective HA/DR
- 10. Business Value of Virtualization
- 11. Cost Reduction
- 12. Types of Virtualization Full Virtualization Para-virtualization (alongside virtualization)
- 13. It's all about Rings
- 14. Rings in virtualization Traditional systems • Operating system runs in privileged mode in Ring 0 and owns the hardware • Applications run in Ring 3 with less privileges Virtualized systems • VMM runs in privileged mode in Ring 0 • Guest OS inside VMs are fooled into thinking they are running in Ring 0, privileged instructions are trapped and emulated by the VMM
- 15. Full Virtualization • Complete simulation of the underlying hardware • Hypervisor contains the Virtual Machine Monitor (VMM) • Guest OS unchanged • Guest uses generic device drivers
- 16. Para Virtualization • The guest OSs cooperate in the virtualization process • Guest OSs are modified, it requires paravirtualized drivers • Thin layer for hypervisor • Offers performance near that of an unvirtualized system
- 17. What Virtualization Provides • Hardware independence – VM sees the same hardware regardless of the host hardware • Isolation – VM’s operating system is isolated from the host operating system • Encapsulation – Entire VM encapsulated into a single file
- 18. Where Virtualization is used ... • Server Virtualization • Application Virtualization • Desktop Virtualization or VDI
- 19. Server Virtualization • Deploy multiple OS on physical servers • Optimum Utilization of Resources • Space utilization efficiency • Easy Migration of machines • Easy and effective DR / BCP
- 20. Desktop Virtualization or VDI • Easy Provisioning • Centralized Management • Reduced downtime in the event of hardware-failures • Desktop image-management capabilities • Longer refresh cycle for client desktop infrastructure
- 21. • Application Isolation • Improved Provisioning • Improved Auditing • Improved IT Control • Improved End User Agility – True portability – Anywhere Access and hot desking Application Virtualization

- 31. Virtualization and Private Cloud Draw a line…..
- 32. Private Cloud
- 33. Virtualization - It's about Infrastructure • Optimizing resource utilization • Manual management of resources like upgrades, patches and maintenance etc. • Manual monitoring and usage • Doesn't provide self service commissioning of resources
- 34. Private Cloud - It's about Service Delivery • Dynamic commissioning and de-commissioning of machines/resources • Provides self service commissioning of resources • Automatic and centralized management of available resource pool • Automatic management of resources like upgrades, patches and maintenance etc.

- The desire to virtualize results from the clear and tangible benefits for company’s of all sizes. It holds the potential to transform business by making them more cost effective, more agile, and more resilient to infrastructure failures. Server consolidation helps reduce capital outlays for server infrastructure purchases and ensures optimal asset utilization. With fewer servers per workload in the IT environment, company’s also benefit from improved power efficiency. Unlike physical servers, virtual servers do not require hardware specific device drivers nor is it necessary to interact with hardware to configure RAID levels, BIOS settings, or network setting. This means that new OS instances and applications can be deployed in a fraction of the time required for physical servers. Because of capabilities like Hyper-V live migration, it is possible to migrate virtual machines among host servers without interrupting the application. This means that server BIOS and firmware updates can occur without taking applications offline, and it is possible to more dynamically match workload demands with the existing supply of compute resources. Finally, server virtualization has brought about a revolution in high availability and disaster recovery. With server instances captured on the SAN, it is now possible to replicate those images across long distances. If a site outage occurs it is possible to rapidly restart VM’s on infrastructure in a DR site without having to have identical hardware configurations at each location.
- x86 CPUs provide a range of protection levels also known as rings in which code can execute. Ring 0 has the highest level privilege and is where the operating system kernel normally runs. Code executing in Ring 0 is said to be running in system space, kernel mode or supervisor mode. All other code such as applications running on the operating system operate in less privileged rings, typically Ring 3.
- Full virtualization uses a special kind of software called a hypervisor. The hypervisor interacts directly with the physical server's CPU and disk space. It serves as a platform for the virtual servers' operating systems. The hypervisor keeps each virtual server completely independent and unaware of the other virtual servers running on the physical machine. Each guest server runs on its own OS -- you can even have one guest running on Linux and another on Windows.
- The para-virtualization approach is a little different than the full virtualization technique, the guest servers in a para-virtualization system are aware of one another. A para-virtualization hypervisor doesn't need as much processing power to manage the guest operating systems, because each OS is already aware of the demands the other operating systems are placing on the physical server. The entire system works together as a cohesive unit.
- On the left: Inherent Attributes of any cloud solution (this is typically what people think of when they think of Public Cloud) On the Right: Bringing in Optimized Management, and control for compliance reasons (these are unique to a Private Cloud Solution) Together they make up the Private Cloud.
- Microsoft and SUSE have developed joint support capabilities to provide compatibility across their virtual machine platforms by taking advantage of the similarity between Hyper-V and Xen Hypervisor. Hyper-V lets IT administrators see how they might consolidate servers, standardize the Linux platform on SUSE Linux Enterprise server for increased performance, and reduce maintenance time with Microsoft System Center. Customers and hosting providers can build on-premises, private-cloud, infrastructure-as-a-service that scales across multiple-source operating systems and applications that use existing hardware and software. In addition to addressing bilateral virtualization, the technical collaboration agreement between Microsoft and SUSE includes collaboration on key systems management standards and directory and identity interoperability, both of which will be critical in helping customers deploy virtual infrastructures that span the Windows and SUSE Linux platforms. System Center Virtual Machine Manager enables IT staff to manage virtualization products and operating systems and applications from multiple vendors, including Linux and VMware ESX. System Center Operations Manager supports monitoring of systems that are not running on Windows, including Linux.
