many European countries have focused recently on building their own domestic data centers, rather than ensuring that European ICT users have access to the cheapest and highest quality cloud data providers.

but it still leads to efforts to get a cloud data center in rural France, instead of helping French EU firms have been less willing or able to reengineer business processes around the use of ICT.

the heaviest computing services are dedicated to virtual data centers powered completely by green energy from a large abundant reserve of natural resources,

have built their data centers near green power sources. Unfortunately many computing centers are not so close to green energy sources.

which makes relocating a data center near a renewable energy source a more efficient solution than trying to bring the energy to an existing location.

The network can transport user service applications to be processed in data centers built in proximity to green energy sources

, such as hand-held devices, home PCS), the heaviest computing services will be dedicated to data centers powered completely by green energy.

In order to move virtualized data centers towards network nodes powered by green energy sources distributed in such a multi-domain network, particularly between Europe and North america domains,

The only difference between the GSN and a regular network is that the former one is able to transport ICT services to data centers powered Switch (Allied Telesis) Raritan UPS (APC) Gbe Tranceiver

Such a management approach is essential for data center migration across a wide area-network network, because the migration must be achieved in a timely manner

Such a migration is required for large-scale applications running on multiple servers with a high density connection local network.

, a new data center) for hosting the application with required configurations, ii) Configuring network connection, iii) Moving VMS and their running state information through this high speed connection to the new location,

However, large scale data centers require arbitrarily setting their complex working environments when being moved. This results in a reconfiguration of a large number of servers and network devices in a multi-domain environment.

thus a 10 Gbit/s link between two data centers can transport more than 300 VMS in parallel.

The migration of data centers among GSN nodes is based on cloud management. The whole network is considered as a set of clouds of computing resources

which provides for a flexible set of data flows among data centers. The ability of incorporating third-party power control components is also an advantage of the Iaas Framework.

in order to move a VM to a greener data center. The process is as follows (Figure 5: i) Copy VM memory between old and new locations,

and forwarding user requests to appropriate data centers. The big picture of the GSN network management solution is shown in Figure 6. The heart of the network is the programmable Federation Stitcher

It links user requests to appropriate services provided by data centers distributed across the network. Each data center is represented by a virtual instance,

including virtual servers and virtual routers and/or virtual switches interconnecting the servers. Such a virtual data center can be hosted by any physical network node, according to the power availability.

There is a domain controller within each data center or a set of data centers sharing the same network architecture/policy.

User requests will be forwarded by the Federation Stitcher to the appropriate domain controller. When a VM or a data center is migrated

the new location will be registered with the Federation Stitcher then user requests are tunneled to the new domain controller.

The first component which is Windows Azure provides Windows based environment to enable users to run applications and store data in data centers.

Virtualization can be important for cloud computing by enabling virtual machine migration to balance the load throughout the data center.

Virtual machine (VM) migration enables robust and highly responsive provisioning in data centers. As a result, it can be concluded that the major benefit of VM migration is to avoid hotspots;

measuring and predicting the traffic to the data centers, especially when they are composed of several hundreds of servers. 6. Data security.

In this case study, Khajeh-hosseini et al. 8 argues that the costs will be 37%less over the 5 years period resulting of transforming an in-house data center to Amazon EC2,

This project will be achieved by leveraging cloud computing technologies in the government data centers of the National Computing and Information Agency (NCIA.

This agency is consisted of two huge data centers that contain thousands of computer systems for about 47 organizations

For example, the media tablet can connect to the corporate data center and can be used to answer all the emails that are related to work

and associated application software from the physical client device that is used to access it 5. 5. 3 Virtualization Strategy This strategy enables enterprises to quickly achieve business benefits gained from IT consumerization by moving the desktop and/or applications into a data center.

and difficulties they confront in continuing to expand their capacity are beginning to reduce their footprint by adopting greener data centers that significantly reduce energy demand.

and physical data centers to the cloud. We see the network as the critical accelerator and enabler in all of these transitions, transforming processes to increase efficiency and decrease costs.

In data centers, for example, the network is the common element for intelligence, scale, and flexibility. Data centers have evolved as more intelligence has been built into the network from networking virtual machines

and developing a platform optimizing computing to scaling applications and decoupling them from the server or data center in

which they live. The network also facilitates the growth of applications, a key driver of the Internet of Everything.

Efficient distribution will require moving the ability to analyze data only in the data center to add processing at the edge (or near the edge) of the network,

Data centers, for example, exemplify the boundaries where electrical power, cooling resources, and space design are redesigned constantly and re-imagined to advance current capabilities.
