ABSTRACT :
In the recent years of fast growing computer technology and networking. We
have attracted toward the new technology called Data Center Network. It is nothing but a
cloud based service providing machanism. In the present all the user data can be accessed,
processed and stored anywhere and anytime. For this purpose we use the data center
concept,which act as a placeholder where all the user data are stored and controlled
remotely. In this research paper we have focus on that data center network
structures,operation and performances.
KEYWORDS – AWS, Data Center Network.
1.
INTRODUCTION
Many cloud services nowadays are running on top of geographically distributed infrastructures for better reliability and performance. They need an more responsive powerful and at a sane time more cost effective way to effectively direct the user requests to a well operable and most suitable data center for processing and serving that requests , in a cost efficient manner. The data centers which are used to create and provide a most efficient cloud services requires a very significant investment in capital planning outlay and ongoing costs. The cost breakdown reveals the importance of optimizing work completed per rupee invested. Unfortunately, the resources inside the data centers often operate at low utilization due to resource stranding and faces the fragmentation problem.
In this years of computer technology development, large investments and research and development have been made in massive data centers supporting cloud services, by famous and multinational companies. The most prominent example for the data center network is Google service. For Example the user can access his/her Gmail account at anytime from anywhere. The are located remotely and are served as the user requested. Internet-scale services are nowadays becoming more essential to our every-day lives, with important applications including web search, video-on-demand, and file hosting. The emergence of cloud computing platforms, such as Amazon AWS[1] further enables rapid deployment of this new data center network technology services at a very large scale. Almost all of these data center network services are built atop of the geographically variant and with largely distributed infrastructures. For Example the data centers located in different and more distributed regions are developed with an aim to provide better reliability and performance. They need an most powerful and at a same time cost effective way to direct clients across the wide area to an appropriate data center.

2. ARCHITECTUREOFDATACENTERNETWORK
The architecture of the Data center network is very simple and more efficient. In the below figure is a typical architecture of data center network.
Fig :1 Architecture of Data Center Network
In this Fig:1 all the CPU structured devices are called as "Data centers". They are connected to a network and when the user wants a service or data, they are served to nook and corned of the globe from nook and corned of the globe.
3. TYPESOFDATACENTERS
The data centers are classified into various types based on their operations and infrastructure. They are as follows
3.1.Macro Data Center
These are most advanced and powerful data center is macro data center. It has the server structure of more than one lakh and can process megawatts of data at a fraction of seconds.
3.2.Micro Data Center
These are also more powerful which are located more closely to the highly populated areas. These are a combination of more than 1000 servers. The main advantage of this data center is it is more independent from physical data centers. It is efficient in the way of cost.
24 www.ijiiet.com 3.3.Nano Data Center
These are more tiny and advanced data center which can be located at the user location it self. The television set up box and Internet modems are the most perfect example of the Nano data center. It is more effective in the aspects of cost.
4. OPERATIONOFDATACENTER
The cloud data center operates in the following manner as follows. For example if a user or a device want to access Gmail account which is located in the server which is located in India from Mecca. The Cloud based data center controlling system of Gmail will first located the user account of the user in the local data center and if not found it will make an extensive search on all this data centers that are present in the network.
If the user account is found than the communication is established between the data centers that are located in India based on the user information. Then the user is allowed to access their Gmail account.
5. APPLICATIONSOFDATACENTERNETWORK
The data centers based on cloud system are used in the following areas of Applications. They are as follows
5.1.Web Hosting
The most important application of the cloud based data center is web hosting. In this the large collection of the websites are hosted or stored. It means the website running in Coimbatore named “www.mohamedimranulhasan.com” will have its content stored in the web server located in some part of Arabia. All these Contents are well organized and that are optimized.
25 www.ijiiet.com 5.2.Social Networking
The Social networking is a place where cloud based data center networks are used. In the Current Social Networking Environment Crores and Crores of people communicate among themselves from different parts of the globe within in a fraction of seconds.
Fig :3 Illustration of Social Networking[3]
All the user information’s and chat records are kept in the Cloud based data center network so the user can access his/her contents from any part of the World at any time. In the above Fig:3 [3] all Worlds peoples across the national borders Express their views, ideas and Emotion.
5.3.Multinational Companies
The multinational Companies are the most important users of the cloud based data center network. Because all their branches which are present all over the world are integrated into one. In Other word it means, an employee sitting in the Coimbatore office of IBM can access the data of the employee in Moscow. This is because of Cloud based data center networks.
5.4.Defense Sectors
The most important application where cloud based data center applications are used are Defense sectors. All the information are made available to all the solders in the defense sectors. These are designed and operated using the cloud based data center networks.
6. ADVANTAGESOFDATACENTERNETWORK
The data center networking technology is the more powerful and more reliable technology which has a lot of benefits. They are discussed below
6.1.Cost Effective
The main advantage of this technology is cost effective. Because it is operated in cloud based sharing mode the is no need for separate infrastructure in each and every place of its need. Since it is cost effective even a small business organization can use this technology.
26 www.ijiiet.com 6.2.Increased Control
Since this is a integrated and cloud based operation it will have a great contribution towards the limitation of expenses. It will require only a limited cables to connect and communicate with it. It will give a greater controlling and monitoring operation.
6.3.High Security
Since it operates on a cloud based setup in addition to the cost effective, time efficiency it will have a high degree of security.
6.4.Recovery From Disaster
The another great advantage of this technology is that it ability to withstand natural and artificial disasters. In the destruction period we can easily recover the data and information's very easily because it has centralized operation.
7. DISADVANTAGESOFDATACENTERNETWORK
The data centers are classified into various types based on their operations and infrastructure. They are as follows
7.1.Bandwidth Problem
The main disadvantage of the data center network is bandwidth problem. Because on line cloud based data center network operation requires high bandwidth. It is main problem in it.
7.2.Limited Control over Security
Since it operates on the cloud based environment all the data and information's are made available on cloud it is very vulnerable to attack.
8. TRUSTMANAGEMENTSYSTEM
The Word of “Trust Management” is derived from social Stream of science which clearly means reliance or belief on another person or entity. Trust Management System operates as an unique component of security features in networks and identified by it as a unified approach. Cloud based Data Center Network which are very easy prey for security threat needs the Trust management to be used. Trust management is used to mold and monitor security policies and relations. Trust management includes trust creation, trust update and trust revocation.

Fig:4 Trust Management System [4]
The trust management system is much essential because it is blood vessel of the Networking operation. In the Above fig:4 [4] all the Communications are done based on the trust. If the trust between the systems are violated all the system will be Collapsed. The Internet server will allow the Communication to access the data available with it only when the trust identity is successful.
9. OPERATIONSOFTRUSTMANAGEMENT
The Trust management system mainly consists of the two major operations. They are 9.1. Probabilistic Reasoning Based Trust Management
In this the trust management is constructed and operated based on the probability Constraints. In is developed based on the certain previous operation and test results.
9.2. Automatic Reasoning Based Trust Management
In this the trust management is constructed and operated based on the Automatic Systems Constraints. In is developed based on the operation and Conditions That are used. The Iron Dome[5][6] that are used in Israel re based on this Trust Management.
10. CONCLUSION
