Wireless Networks and Security

Question: Discuss about the Wireless Networks and Security. Answer: Introduction Wireless Cloud Computing or Cloud Computing is the next big thing that is happening in the IT industry currently. Cloud Computing can help any company to analyze huge data and also helps them to store the data. The data that is stored over the cloud is non-contagious. Cloud Computing offers verities of services like SaaS, PaaS and IaaS [3]. All are unique in their own way and offers features for different purposes. Cloud Computing can be achieved by two ways that either by Service Providers or installing a system in own firm. In order to have efficient data management services, it should be scalable and elastic. There are many companies that provide cloud services like Google, Amazon, Cisco and many more [2]. The main advantage of using cloud computing is that it can be accessed from any part of the world and the security that is offered by the cloud technologies are also quite superior that is no unauthorized access is allowed. The following article discusses about the Wireless Cloud Computing and how it managed to make its way through various developments in the technological areas. Architecture and Standards Wireless Network Cloud or WNC is technology that can be used for the next generation of wireless access networks. The system makes uses the emerging cloud technology which further involves wireless infrastructure like IT based Software Defined Radio or (SDR) technology and also contain Remote Radio Head (RRH) technology. Wireless Network Cloud helps in by changing the existing wireless communication infrastructure and integrating it with multi core processors, provides high speed transmission of data, virtualization and also cloud computing [1]. The radio frequencies which were previously generated by incompatible RAN base will now be generated with the help of software. Different standards will now have supports for different software with the help of software upgrades. This method will help the telecom operators to reduce the construction cost as well as help them to utilize the resources too. With the help of sharing processing capabilities that will set a link between virtualized base station and it can be further used to reduce interference between base stations and will also help in improving the network coverage [2]. The main aim of having cloud architecture is to provide the users with high bandwidth which allows them to have unlimited access to data and applications and cloud computing also offers efficient working which allows them to switch between servers and even between clouds and more importantly it gives network security [5]. There are various cloud based services are available which have their own unique features which makes them stand alone from the rest. The first is the SaaS or Software as a Service which generally involves the software hosted part over the internet and with SaaS; users do not have to install the software locally as it can be installed over the cloud. The second is the PaaS or Platform as a Service which helps uses with application platforms and includes the databases which mainly work like middleware services. The third is the IaaS or Infrastructure as a Service which offers infrastructure and hardware for servers, networks, storage devices and many more [6]. Opportunities and Challenges Wireless cloud computing is the next big thing that is currently happening in the information technology sector. The data that are stored are non contiguous and in order to store the data, first the data needs to be organized and later it can be analyzed and process [1]. In order to have efficient data management services, it should be scalable and elastic. Opportunities Wireless Cloud computing has many opportunities as it is slowly evolving and is being adopted by many organizations. Health Care Organizations are also implementing this cloud services within their organization which helps them to get significant level of comfort for their organizational operations which helps them for effective monitoring of many parts of the organization and with this less resources are being utilized [4]. They need to analyze and process huge data and wireless cloud services which helps them to achieve this as with cloud computing it becomes very cloud cost efficient and also helps them to store and process large amounts of data. Using wireless cloud computing also helps them to get over the security challenges as Health Care Organizations has got some very sensitive data which needs real protection. Wireless Cloud Computing also helps many companies to store their data over the cloud and also helps them to access it from anywhere [8]. Challenges With the rise of Cloud Computing, there are many challenges that is facing. Some challenges may be mediocre and some are really alarming. The main challenge that Cloud Computing faces is that of the security issues as many companies have shifted to cloud computing technology so it is really important that the security with cloud computing should be enhanced so that there is no data leak and also one cannot access the data without proper authorization [10]. Examples and Case Studies Examples of Wireless Cloud Computing include the Amazon EC2, Google App Engine, Google Apps and Microsoft Office Online and Apple iCloud [2]. Case Studies There has been a major shift when City of Los Angeles migrated on using Google Mail. This migration includes around seventeen thousand users. The main reason of this shift is due to the fact that Google Gmail provides cloud based features in their mailing system which helps them to keep their data much secured [9]. Easyjet also shifted its organization on using cloud computing in order to lower the cost and by doing so; they saw a growth in their business. Easyjet is quite familiar with outsourcing which greatly benefits the company on using cloud computing. By using cloud services, their main aim was to transfer all their sensitive data over the cloud. D-Link is quite famous when it comes on making network related products. D-Link also shifted to cloud computing by moving their vast majority of non-ERP application to the cloud which helped them to improve their enterprise and also helped them to tackle more efficiently with the risk management and also significantly decreased the IT costs. The biggest benefit that the company saw on moving to cloud computing is that many IT organizations responded on their move and from which they made huge success [12]. Sanimax is also an example in which a small or medium sized business is using the hybrid cloud services. Sanimax is gradually implementing SaaS in their systems which help them to install every application over the cloud and not locally which helps every member of their company to use directly these features. Sanimax also uses ERP as its cloud service when it was launched. This shift has helped them to shift from capital to operational costs and also gave them the feature to scale up and down as per their needs [11]. Any other Key Relevant Information Wireless cloud computing helps the companies to store large amount of data over the cloud which makes possible for the analysis of these data much easier. It also helps in retrieving the data and the data that is stored will automatically generate a backup file so that even during any disaster, it can be retrieved. Another advantage of having wireless technology is that it can be accessed from any part wirelessly [7]. Conclusion Wireless Cloud Computing is gradually pacing its steps as the most influential technologies that can happen in the IT industry and is making a ground breaking attempts to show how IT resources are managed and utilized. With the help of Wireless Cloud Computing, many businesses can adapt to this without paying huge sum of money in the beginning and this helps the company to flourish more. However there are still some drawbacks which limit the users on using it and the main is the security issue as cloud computing aims to provide large storage of data which the company can use to store their sensitive data. But they fear of losing the data as there are many security holes that are present in the cloud computing. Cloud computing also aims to provide virtualization which helps the companies to get a clear picture about the company so that they can take steps accordingly. Cloud computing is developing rapidly and a great promising future prospect. With this, companies can also meet new ch allenges and enhance their plans. As well as, the security of cloud computing is not only technical but also includes standardization, supervising models, laws and regulations and also contains many other aspects.
