Virtualization allows multiple operating systems and applications to run on a single computer using a hypervisor. It is considered green computing because it decreases energy usage and toxic waste by reducing the number of physical devices needed. There are several types of virtualization including server, application, network, storage, and desktop virtualization. Server virtualization specifically allows many virtual servers to run on a single physical server, decreasing energy usage and saving floor space. Overall, virtualization improves hardware utilization and flexibility while lowering costs and environmental impact through reduced resource consumption.

Cloud computing & energy efficiency using cloud to decrease the energy use in...Puru Agrawal
Cloud can be used to decrease the energy use in large companies. This presentation deals with a model which explains as how cloud can be used to decrease the energy uses. This is a field related to green computing and minimum use of energy resources.
Presentation detailed about SDN (Software Defined Network) overview . It covers from basics like different controllers and touches upon some technical details.
Covers Terminologies used, OpenFlow, Controllers, Open Day light, Cisco ONE, Google B4, NFV,etc
ABSTRACT
Cloud computing promises to significantly change the way we use computers and access and store our personal and business information. With these new computing and communications paradigms arise new data security challenges. Existing data protection mechanisms such as encryption have failed in preventing data theft attacks, especially those perpetrated by an insider to the cloud provider. For securing user data from such attacks a new paradigm called fog computing can be used. Fog Computing is a paradigm that extends Cloud computing and services to the edge of the network. Similar to Cloud, Fog provides data, compute, storage, and application services to end-users. The motivation of Fog computing lies in a series of real scenarios, such as Smart Grid, smart traffic lights in vehicular networks and software defined network .This technique can monitor the user activity to identify the legitimacy and prevent from any unauthorized user access. Here we have discussed this paradigm for preventing misuse of user data and securing information.

Virtualization is a technique, which allows to share single physical instance of an application or resource among multiple organizations or tenants (customers)..
Virtualization is a proved technology that makes it possible to run multiple operating system and applications on the same server at same time.
Virtualization is the process of creating a logical(virtual) version of a server operating system, a storage device, or network services.
The technology that work behind virtualization is known as a virtual machine monitor(VM), or virtual manager which separates compute environments from the actual physical infrastructure.

Detecting local attraction
For detecting local attraction it is necessary to take both fore bearing and back bearing for each line.
If the difference is exactly 180°, the two stations may be considered as not affected by local
attraction.
If difference is not 180°, better to go back to the previous station and check the fore bearing. If that
reading is same as earlier, it may be concluded that there is local attraction at one or both stations.

2. What is virtualization ?
•Virtualization is one of the hardware reducing, cost saving and energy saving technology that is rapidly transforming the IT landscape and fundamentally changing the way that people compute.
•On a server or a desktop PC, it allows multiple operating systems and multiple applications to run on a single computer.
•The software that makes this possible is known as a hypervisor.
3. Why it’s green
•Decreased energy use: reducing the number of physical devices, the amount of energy required to operate the devices is decreased. Also the amount of energy required to cool the environment and the system.
•Reduction in toxic waste: since the number hardware devices are decreased, there is a huge decrease in e-waste and hence reduction in toxic wastes.
•Reduction in facility requirements: If the amount of equipment is reduced, so are space requirements, which means business can increase without having to build ever larger data centres.
5. Server virtualization
•It allows many servers to run on the single physical server.
•Advantages
1. Decreased energy usage.
Having fewer servers
means less energy is
needed to power and
cool the servers.
2 . More floor space. Reducing the
number of servers can reduce the
amount of space needed, or at
least allow you to use the space
more efficiently.
6. Application virtualization
•Allows applications to run independently of the underlying host operating system.
•Advantages:
1.Because no device drivers
are installed or registry entries
made, applications can be
deployed without having
administrative rights.
2.Applications that are incompatible
can be safely run on the same
physical machine.
3.Applications can be executed from
portable media.
7. Network virtualization
•It allows us to combine
all of the resources available
on a network by
splitting up the available
bandwidth into
independent channels.
•Advantages:
1.Consolidation of many physical networks into one virtual network.
2.Partitioning of a single physical network into many virtual networks.
8. Storage virtualization
•Allows multiple storage devices to be combined as a one large storage device.
•Advantage:
1.Easier administration as
virtualized storage can be
managed from a single
administrative console.
2.Storage growth can be closely
monitored and managed,
making upgrade planning easier.
9. Desktop virtualization
•allows virtual desktops to be centrally managed on a server and run by the end user on a thin client machine.
•Advantages:
1.Access to typical desktop
features, such as multiple
monitors, USB devices.
2. Disaster recovery at the
desktop is simplified, as a new
device can be quickly installed to
use the virtualized image on the
server. Backups can be managed at
the server level.
10. Technology options
•VMWARE EXS
Advantages are:
1.Any operating system or the application can be run in a virtualized environment without any modification.
2.It supports all intel and AMD processes, so it can work with older machines.
3.Its Vproduct will allows the user to migrate the virtual machines from one physical server to another while running.
4.With Virtualization it is possible to run multiple operating systems and multiple applications on the same SERVER at the same time, increasing the utilization and flexibility of hardware.
