Vmware virtualization in data centers

VMware provides virtualization software that allows guest operating systems to run on virtual machines. This makes virtual machines highly portable between physical computers. Administrators can pause, move, or copy virtual machines. Virtualization treats hardware as a pool of resources available on demand. VMware was founded in 1999 and initially developed virtualization in the 1960s for mainframe computers. It offers two types of hypervisors - Type 1 is a bare metal hypervisor directly on hardware while Type 2 is hosted on a traditional operating system. VMware helps enterprises consolidate servers, provision applications quickly, isolate workloads, enable disaster recovery, and reduce costs. Welch's Foods case study showed VMware helped save over $100,000 by migrating servers to

VMware and Data Center Virtualization By: Murli Bhatnagar-18BCS4089 Harshit Taneja-18BCS4103 Naman Parashar-18BCS4107 Yashasvi Bakshi-18BCS4069

VMware software provides a completely virtualized set of hardware to the guest operating system. The VMware virtual machines become highly portable between computers, because every host looks nearly identical to the guest. A systems administrator can pause operations on a virtual machine guest, move or copy that guest to another physical computer. Hardware seen as pool of resources available on-demand on an arbitrary basis. Virtualization
History of Virtualization Initially developed in the 60’s to leverage the usage of mainframe computers. Each user sees the machine as fully dedicated (timeslot multitasking). Deployed from the late 60’s to the mid 80’s, then abandoned in favor of the emerging mini and microcomputer architectures. VMWARE appears after successful reutilization of the virtualization concept for a (non-standard) multiprocessor prototype. Standard software could be run using middleware. (Stanford University). Investigation team founds VMWARE in 1999. First desktop product in the same year, server version in 2001.
VMware Server Becomes the lowest software layer, just above hardware. Alternative architecture (addresses I/O concerns):
TYPE1 TYPE2 It is an Operating System (OS) It installs and runs on x86 bare metal hardware. It requires certified hardware Very high resources are not consumed by bloated parent operating system Better performance as compared to Type 2 Example: VMware ESXI and Citrix Xen Server Bare Metal Hypervisor: It installs and runs as an application. It relies on operating system (OS) running on physical machine for device support and physical resource management Performance reduces due to less direct interact with hardware. Example: KVM, VirtualBox, etc. Hosted Hypervisor: Types of Hypervisor
VMware in the Enterprise Consolidation of servers Fast provisioning Isolation of Applications Run legacy software Elastic operation Disaster Recovery Fail Over Reduced Carbon Footprint- Green Computing
Virtualize data centers Compute vSphere VMware vSphere leverages the power of virtualization and enables transformation of Classic Data Centers (CDCs) into Virtualized Data Center (VDC), which is the foundation for cloud computing infrastructures. vSphere aggregates the underlying physical x86 based hardware resources across multiple systems and provides a pool of virtual resources. The VMware vSphere consists of the components shown on this slide. VMware vSphere also provides additional modules and plug-ins, such as VMware Distributed Resource Scheduler (DRS), VMware High Availability (HA), and VMware Data Recovery.
Virtualize data centers Compute vCenter VMware vCenter Converter is a highly robust and scalable enterprise-class migration tool that automates the process of creating virtual machines from physical machines and other virtual machine formats (for example virtual machines created using Microsoft Hyper-V). VMware vCenter Converter lets users quickly, easily, and affordably convert Microsoft Windows and Linux-based physical machines to VMware virtual machines. It also converts virtual machines between VMware platforms.
Advantage Encapsulation : strong isolation, independence between guest machines. A VM is a file: can be copied, replicated, transmitted (migrated), stored. Complete VM can be deployed from templates, ready with configuration and data. Hardware seen as pool of resources available on-demand on an arbitrary basis. Consolidation of physical underutilized servers. Run legacy applications / platforms. Ideal platform for disaster recovery
Disadvantage Licensing compliance for operating systems / applications must be complied to. Each guest must still be administered. Inter-guest interactions difficult to monitor. Compromise of Server can disrupt all the guests. Administrative errors on server can disturb all guests. User might have to face Application Downtime
“We migrated a large number of servers into VMware virtual machines. We saw how well the applications performed, and we never looked back. At this point, all new programs are built using VMware software. It’s become our server hosting platform of choice.“ -Carmine Iannace, Manager of IT Architecture, Welch’s Case Study- Welch's $700M Foods and Beverages Industry Company
Case Study- Welch's Challenge: Server consolidation and optimized management Solution: VMware virtual infrastructure provides centralized management, reporting, performance and high availability. Saved more than $100,000 Saved $75,000 this year in switch costs Expect to save $250,000 by the end of the year CPU utilization increased from 5-10 percent to 50-60 percent Reduced deployment time from 4-6 hours to 15-20 minutes. Server procurement also used to take 2-4 weeks VirtualCenter cut costs and maximized ease of server management Results:
