APA ITU VIRTUALISASI Virtualisasi bisa diartikan sebagai
pembuatan suatu bentuk atau versivirtual dari sesuatu yang bersifat fisik,misalnya sistem operasi, perangkatstorage/penyimpanan data atau sumberdaya jaringan dalam bentuk file
Bentuk Virtualisasi Network Virtualization Memory VirtualizationGrid Computing Application Virtualization Storage Virtualization Platform Virtualization
KEUNTUNGAN VIRTUALISASI Hardware Investment Cost Reduction Ease Backup & Recovery Ease of Deployment Reduce heat
KEUNTUNGAN VIRTUALISASI Reducing the Cost of Space Ease of Maintenance & Management Standardization Ease of Replacement

Konsep Virtualisasi
Jenis Aplikasi Populer Virtualisasi VMware KVM Xen
VMwareOnly available version 5.5 workstation for
LinuxMax Performance in MS Windows
Enviroment Very popular VM
KVM Support build in Kernel Linux Fully Open Source Easy of installation and configuration
using Proxmox
XenMemiliki Teknologi PV (Paravirtualization)
dan HVM (Hardware Virtual Machine) Has a free and paid version (Citrix
XenServer) Amazon, AMD, Cisco, Citrix, Intel, Oracle,
Samsung, and Verizon Use it.
Arsitektur Xen
Komponen Xen The Xen HypervisorGuest Domains/Virtual Machines The Control Domain (or Domain 0) Toolstack and Console: Domain 0 Xen-enabled operating systems
Xen PV Advantages Runs a full unmodified OS, excluding
bootloader + kernel Can compile and load your own kernel
modules Highly scalable, low overheads Easy OS reloads with precreated templates Direct allocations of RAM + HDD, not oversold
and cannot be used by other VPS Easily upgraded/downgraded or migrated to
another host machine if required
Xen PV Disadvantages Supports Linux only Limited to only the precreated OS
templatesCan't modify the OS options during installCan't compile and install a custom kernel
unless using Pygrub Fixed two filesystem layout with two
partitions, one for hdd one for swap
Xen HVM AdvantagesComplete and secure isolation Run Linux, Unix, BSD or WindowsCustomize your kernel, and even your
partition layouts Behaves exactly like a real physical server Large ISO library updated reguraly
Xen HVM Disadvantages Slower / more time comsuming re-installs Higher overheads than Xen PVMore dificult to upgrade/downgrade or
migrate to another host machine if required
