This document provides an overview of virtualization and cloud computing technologies. It defines virtualization as using software to allow multiple operating systems to run on a single hardware host. A hypervisor manages shared access to the physical resources. The document outlines the history of virtualization and describes popular virtualization platforms like Hyper-V, VMware vSphere, and cloud services from Amazon Web Services, Google Apps, and Windows Azure. Benefits of cloud computing include reduced costs, increased storage, flexibility, and mobility. Public, private and hybrid cloud models are discussed along with case studies of major cloud providers.

3. What is Virtualization? Virtualization is a proven software technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute, such as an operating system, a server, a storage device or network resources.

4. What is Hypervisor Layer? A hypervisor, also known as a virtual machine manager/monitor (VMM), is computer hardware platform virtualization software that allows several operating systems to share a single hardware host. Each operating system appears to have the host’s processor, memory, and resources to itself. Instead, the hypervisor is controlling the host processor and resources.

5. Hypervisor Classifications Bare Metal/Native Hypervisors: Software systems that run directly on the host’s software as a hardware control and guest operating system monitor. A guest operating system thus runs on another level above the hypervisor. This is the classic implementation of virtual machine architectures. Embedded/Host Hypervisors: Software applications that run within a conventional operating system environment. Considering the hypervisor layer being a distinct software layer, guest operating systems thus run at the third level above the hardware

6. History of Virtualization Virtualization was first implemented more than 30 years ago by IBM as a way to logically partition mainframe computers into separate virtual machines. These partitions allowed mainframes to “multitask”: run multiple applications and processes at the same time

7. Microsoft Hyper-V Features 32-bit (x86) & 64-bit (x64) VMs Large memory support (64 GB) per VM Integrated cluster support for HA & Quick Migration BitLocker: Seamless, secure data encryption Live Backup: Volume Shadow Service integration Pass-through disk access for VMs Virtual Machine snapshots New hardware sharing architecture Disk, networking, input, video Robust networking: VLANs and NLB Support for Full or Server Core installations

8. Microsoft SC VMM 2008 Maximize Resources Centralized virtual machine deployment and management for Hyper-V, Virtual Server, and VMware ESX servers Intelligent placement of Virtual Machines Fast and reliable P2V and V2V conversion Comprehensive application and service-level monitoring with Operations Manager Integrated Performance and Resource Optmization (PRO) of VMs Increase Agility Rapid provisioning of new and virtual machines with templates Centralized library of infrastructure components Leverage and extend existing storage infrastructure and clusters Allow for delegated management and access of VMs Leverage Skills Familiar interface, common foundation Monitor physical and virtual machines from one console Fully scriptable using PowerShell

9. VMware vSphere Features VMware vSphere comprises a number of components that transform industry standard hardware into a shared, main-frame like resilient environment with built in service level controls for all applications. The components of VMware vSphere are classified into: Infrastructure services for example {ESX - ESXi} These are components that comprehensively virtualize server, storage and network resources, aggregate them and allocate them precisely on demand to applications based on business priority. Application services for example {Vmotion - vStorage - HA - Data Recavery} These are components that provide built in service level controls to all applications running on the Cloud OS platform, regardless of application type or operating system. VMware vCenter Server provides a central point of control for virtualization management, essential for administering infrastructure and application services.

15. What is Cloud Computing? Cloud computing consists of shared computing resources that are virtualized and accessed as a service, through an API. The physical resources may reside in a number of locations inside and outside of an organization: on local hardware, in an enterprise data center, or at remote or managed service providers on a pay-to-use basis. The Cloud services are divided into three categories: - Infrastructure-as-a-Service - Platform-as-a-Service - Software-as-a-Service. Infrastructure Platform Software

16. Benefits of Cloud Computing. Reduced Cost Cloud technology is paid incrementally, saving organizations money. Increased Storage Organizations can store more data than on private computer systems. Highly Automated No longer do IT personnel need to worry about keeping software up to date. Flexibility Cloud computing offers much more flexibility than past computing methods. More Mobility Employees can access information wherever they are, rather than having to remain at their desks no MORE VPN Required. Reducing IT Stuff You don’t have to hire more IT Stuff for special purpose, your small IT stuff will do the best.

17. Benefits of Cloud Computing. The power of choice

19. Google Apps Google App Engine lets you run your web applications on Google's infrastructure. App Engine applications are easy to build, easy to maintain, and easy to scale as your traffic and data storage needs grow. With App Engine, there are no servers to maintain: You just upload your application, and it's ready to serve your users.

20. Amazon Cloud Amazon Elastic Compute Cloud (Amazon EC2) is a web service that provides resizable compute capacity in the cloud. It is designed to make web-scale computing easier for developers. Multiple Locations Elastic IP Addresses Virtual Private Cloud Elastic Load Balancing Auto Scaling

21. Windows Azure Windows Azure offers a platform that is easily implemented alongside your current environment. - Windows Azure: operating system as a service- Microsoft SQL Azure: fully relational database in the cloud- Windows Azure platform AppFabric: makes it simpler to connect cloud and on-premises applications Pricing # Compute = $0.12 / hour # Storage = $0.15 / GB stored / month # Storage transactions = $0.01 / 10K Windows Azure is now commercially available. Usage during the month of January 2010 will be at no charge. We will begin charging customers on February 1st, 2010
