Virtualisation with v mwarePresentation Transcript
Virtualization – what is it?
Separation of a resource or a request for service from the physical
delivery of the service
Provides a layer of abstraction between computing, storage and
networking hardware and the applications running on it
Virtualization makes possible:
Hardware independence of OS and applications
Virtual machines can be provisioned to any system
OS andApplication can be encapsulated into one virtual system
Each virtual machine represents a complete system with processors, memory,
Virtualization - Concepts
Running multiple services on the same machine and sharing the underlying
Hosted approach provides partitioning services on top of a standard OS
Hypervisor architecture – layer of software first installed on a clean x86 system
More efficient as it has direct access to hardware resources

VM Ware Product for
VMware Infrastructure Flagship product to build virtual data centers
VMware ESX Server Hypervisor
VMware Server Uses the Hosted Approach
Vmware ESXi Free download
VMware vCenter Management and provisioning of virtual machines, workload
consolidation across physical machines
Vmware ESX Server is the building block of VMware Infrastructure
VMware Infrastructure: Virtual DataCenter OS
Application vServices guarantee availability, security and scalability to applications.
Infrastructure vServices abstract, aggregate and allocate on-premise servers, storage and network
Cloud vServices federate the on-premise infrastructure with third party cloud infrastructure.
Management vServices help manage the virtual datacenter OS and the applications running on it.
Virtual DataCenter OS: Products & Services
Application Services Function
VMware VMotion Eliminates disruption through live migration of running VMs
VMware Storage VMotion Eliminates disruption thru live migration of VM disk files across storage
VMware HA Enables restart of virtual machines in the case of hardware failures
Enables VM backup and restore
VMware DRS Enables Priority based management of apps
VMware vStorage VMFS Cluster file system that allows multiple versions of ESX server read-write access to the
same virtual machine storage concurrently

Management Services Function
VMware vCenter AppSpeed Enables centralized applications management
VMware vCenter Server Enables centralised management
VMware vCenter Lifecycle Manager Enables policy driven provisioning and lifecycle management of virtual
VMware vCenter Update Manager Enables automated enforcement of patch policies
VMware vCenter Site Recovery Manager Enables automated disaster recovery processes
VMware Product Portfolio: Desktop
VMware Product for
VMware View Delivers desktops to users and not to a machine by decoupling a
desktop image and the physical PC . Allows centralised management
VMware Workstation Runs multiple operating systems simultaneously on a single physical
Runs multi-tier enterprise applications (client, server, database virtual
machines) on a single piece of hardware.
VMware Thin App Uses application virtualization to decouple applications from operating
systems thereby allows an application on multiple operating systems
Vmware ACE Provisions standardized client PC environments inside secure,
centrally managed virtual machines called ACEs. Each ACE contains a
complete client with device and network access control, there by
protecting confidential data and compliance with IT polices.
VMware Fusion (For the Mac) Allows Windows’ applications on Mac
VMWare Product: Mobile
VMware MVP:VMware MobileVirtualization Platform
A thin layer of software embedded on a mobile phone to decouple
the applications and data from the underlying hardware.
It is optimized to run efficiently on low power consuming and
memory constrained mobile phones.
Currently supportsWindows CE 5.0 and 6.0, Linux 2.6.x,
Symbian 9.x, eCos, µITRON NORTi and µC/OS-II.
Accelerate time to market by is reducing the effort in porting the software
stack for multiple mobile platforms.
Easily migrate to richer Oss
Allows multiple personas for the user.
OpenVirtualization Format (OVF)
how virtual appliances can be packaged in a vendor-neutral format to be run
on any hypervisor.
VirtualAppliances are pre-built software solutions, comprised of virtual
machines packaged, updated, maintained and managed as a unit.
Virtual Machine Disk Format (VMDK)
Describes the virtual machine environment and how it is stored. (critical to
how virtual environments are provisioned, manipulated, patched, updated,
scanned and backed up.)
Vmware has released a toolkit for developers creatingVirtual Disk
management applications .
