5. Virtulaization Scalability Methods
▫ User allocation
▫ Data redundancy
▫ Security
▫ Bandwith
▫ Authentication and security
▫ Available users of simultaneously

6. Redundancy Methods
6
Mirroring Server
by using a backup server
that duplicated over all
processes and the data
transmissions from the
primary server. when the
primary server get failure
the backup server will be
up.
Server Image Backup
Server image backup is an
activity like precaution for
the server setups. It store
in the image file what are
the set up been done in
the server. When we need
again we can restore the
image so all the settings
will be applied again.
Load Balancing
Load balancing server
works as the traffic police,
because in the server
there will be millions of
data transmission at once.
So to balance the traffic
and availability the load
balancing servers are
used.
7. Support Centrlaization of services and
testing of resources
How much important is a Support?
▫ There will be more and more answers but the one is very important. the servers and the
service providers are having the monitoring resources as well support team.
▫ There is a tools call Nagios. This monitor the server performance and automatically will send
the report to the support team. From the support they will do the needful.

8. Conclusion
According to the scenario the folowing topics has to be covered
when implemeting vituliazation environment.
▫ Data Redundancy
▫ Bandwith speed
▫ User allocation
▫ Storage
▫ Availability
▫ Accebility
▫ Security

10. Environmental Server Deployment
▫ Reduce Hardware cost
▫ Faster service deployment and
provisioning.
▫ Disaster Recovery
▫ Energy is saved
▫ Increasing the productivity.
Benefits of Virtualization
Remote Desktop and Web based
▫ Managing from anywhere
▫ Remote support
▫ Can solve any issue from
anywhere.
▫ Easy to access.
10
11. Server Based
▫ VMware – it is provide the
virtualization as well cloud computing.
▫ ESXi – it is an Operating system which
provide by VMware. It is a Hypervisor
which is running directly on the
hardware.
▫ Citrix – It is used for Microsoft Terminal
Services. These used for the security of
the data that transfer through the
virtually.
Solutions
Desktop Based
▫ Parallels – which is used in MAC to
use Microsoft windows, linux, as well to
use google chrome.
▫ QEMU – it is a hypervisor also like a
virtual box. This also can emulate
machines devices like ARM board. Also
used with KVM. To provide the best
performance.
▫ VMware Player – it is a desktop
virtualization application. It can work
with 32bit or 64bit.

13. Current technology requirments
Hypervisor
ESX Server or Hyper-V,
load the management
platform of integrated
also Microsoft SCVMM
or VMware vCenter add
the virtual hosts to the
managing stage.
Virtual Drivers
When we use the
virtual machines it
should have the proper
drivers. The vmtools
VMware KB 340 is the
responsible for the
drivers.
Network connetions
(NAT, bridged)
NAT is used as firewall
which is limit the users
amount as well control
the IP addresses which
is from unknown
network.
Bridged technology is
control the network
traffic within the LAN
network only.

14. Environments for developers.
Arrays of Server
This the called as
dedicated storage for
the developper in the
vitual machines. It will
be deffined as block or
file based.
Cloud Computing
It is most trending
virtual technology for
not only th developpers
who needs the more
storage with low cost
also redundant. Azure
and AWS are most
popular cloud storage
providers.
Web Servers
This will not be
dedicated fully but it
will be virtualized for
the web hosting. Also
these are the low cost
for web development.
14
15. Cost
▫ Haredware cost reduction it is mainly a best advantages of the virtualization
because we don’t need to have physica serever, place, elctricity, resources
also maintnace expencesthis all make the cost reduction when deploy a
virtualization.
▫ Cost of ownership the organiation no need to spend much money but when
deploying a virtual servers have to spend some mony which is less cost than
physical server.
▫ Reduction of upgrade cost will be another impact on the vitualiation
environment. Because the vendeors will be responsible for the storage and
any changes. Only the organization has to pay the estimatedcost for the
storage monthly or yearly.

16. Conclusion
According to the scenario the Virtualization deployment for BCIT project has
to be done in following has to be considered.
▫ User allocation
▫ Disk utilization
▫ Resource availability
▫ Network Bandwidth
▫ Redundancy
