Telecommunications and Networking Issues - Essay Example

?Telecommunication and Network By Table of Contents Task Cloud computing: An overview The term cloud computing refers to usage of resources related to hardware as well as that are completely accessible via internet and managed through third party services. The term cloud is usually used for the representation of internet. Nevertheless, these services characteristically offer way in to complex and highly developed software applications and also towards server computers usually used for high end networks (Mitchell, 2011). In this scenario, many service providers construct such sort of cloud computing systems that are useful in serving general research or business needs. A lot of examples are there but some of the examples related to cloud computing are as follows: (Mitchell, 2011; Mudge, 2010) Software: software makes the most use of saleable software applications, it is used for development and distantly host applications (customer built applications). Network Storage: usually network storage is used for back up or also it is useful for storage data crosswise the internet to a provider. Hence it is not necessary to know the substantial location of storage. Moreover, cloud computing systems normally are designed in such a way that they could upload scalability to maintain large numbers of consumers and surges according to required demand (Mitchell, 2011).  Basically the two terms, cloud computing and other working in the cloud computing in the direction of performing computer related tasks via services are delivered completely via internet. Another aspect that is reviewed generally is that cloud computing is considered as a movement far away from those applications that are required to be installed lying on an individual's computer towards those applications which are hosted online. (The term cloud computing can be divided into two parts, one is "cloud" that refers to the internet and stimulated by technical and scientific flow charts with diagrams, however, this specification leads to the usage of a cloud symbol to symbolize the internet (Pinola, 2011). Types of Cloud Computing The specifications that are mentioned above pass on to software related solutions which are easily provided over the internet, or in Software as a Service that can be abbreviated as (SaaS). There are also other cloud computing applications that comprise of virtual server storage (Infrastructure as a Service) or IaaS. There are a lot of examples over the internet such as and software and product development tools (Platform-as-a-Service or PaaS) e.g. Google apps and Amazon web services (Pinola, 2011). Examples of Cloud Computing Services Internet has facilitated us with web based email services. Moreover, we have the examples of Hotmail and Gmail that carry out a lot of cloud computing service. Hence, users can view in their email in the cloud from any user’s computer that requires internet connection with installed browser, we need not to worry about what sort of hardware is installed on that specific computer. The electronic-mails (email) are hosted on Microsoft as well as Google servers, instead of being stored on the client computer or locally. Moreover, we have seen extraordinary growth in cloud computing over the previous few years, and many popular Web apps as witnessed which are commonly used today. These web applications include VoIP (voice over internet protocol). We have the example of Google Voice and Skype, also social applications which include some of the well known networks such as Twitter and Face book, the facility of media services e.g., Picassa, YouTube, Flicker and for content allocation we use e.g., Bit Torrent. Moreover, financial applications e.g., Mint and a lot of others. Another growth aspect in the field of cloud computing can be visualized in traditional desktop software which has stimulated in part to the Web, and it starts with its applications (Pinola, 2011), (Nations, 2011; Ingthorsson, 2010). Cloud Computing is a Service Storage and information retrieval are the simplest operations that a computer allows to its users. We can easily store our personal data like family photographs, our desired songs, or even accumulate and download movies on it. This is as well the mainly essential service that is offered by cloud computing. We have a great example of Flicker which we often use, is a cloud computing service. In addition, Flicker is an ongoing application with prominence on the distribution of images and photos. First thing is that, Flicker allows us to by far access our images. Moreover, it does not depend on where we are no matter what type of device we have. While uploading the required material we can simply access them from your personal computer or on laptop or even from our phone while sitting anywhere. Second, Flicker lets us share the images. There is no need for a compact disc or keep them on a flash. Third aspect is related to data security, Flicker provides security of our data that may be vital for us or some organization. In case we have lost our data we can create a backup on the web (Nations, 2011; Ingthorsson, 2010). Cloud computing and networking technology Cloud computing generally offers a lot of convincing benefits for common users and organizations that used it, such as it is useful in many ways. It facilitates organizations with the cost of operations performed reduced capital and scalability according to our demands. So we are in right opinion towards business concerning matters to take full fledging advantage of the on-going computing resources and services according to our demands, collectively known as “the cloud”. We know Cisco is a leading network oriented company is working with other industry leaders on joint venture to develop and expand protocols and standards that are useful in transformation of the long-term vision the Inter-Cloud form, today into reality. If the Cisco joint venture happens then it will make considerable changes in the cloud environment, further than the technology directions must change in this regard. The IT related organizations, and how IT (information technology) mechanism with various business units, have to acclimatize as well, or organizations won't get the entire what they desire from the cloud computing (Nations, 2011; Ingthorsson, 2010). If we research the Cloud Computing like both a service delivery model and technology concept, particularly according to its networking point of view, and also its various implications indeed. We already have studied the existing and promising technologies related to networks usually used in the Cloud computing, either in internal level or in external, it may include various aspects that correspond to WAN (wide area network) technologies as well as Data hub/centre interconnections. If we analyze the both Long-distance interconnections (MAN and WAN), the overall spectrum between information centers are visibly based on IP (internet protocol) standards that are used over the ATM (auto transit machine), Ethernet, SDH/ SONET and further recently, on MPLS with QoS as well as interconnection that have local capabilities. If we need high bandwidth in addition to ultra low latency, we have to use Dense Wavelength Division Multiplexing (DWDM) that appears to be exceptionally capable and promising as a future high performance wide area network (WAN convey technology which is mainly used for transportation in between, due to its challenging capabilities of multiplexing that are required in multiple visual/optical signals, however, being protocol along with bit rate that is autonomous. Furthermore, towards the horizon of cloud computing, advanced WAN network technologies are tranquil on the investigate/research stage, including the idea which is known as Lambda networking .moreover, lambda networking promises high capacity circuits and low cost in extensive haul along with metro systems (Nations, 2011; Ingthorsson, 2010). We know about a fact that within data centers, nevertheless, where the system servers, network nodes/elements and storage systems are interconnected with each other; there are three LAN network technologies that we used almost are as following: (Nations, 2011; Ingthorsson, 2010) Ethernet Fiber Channel Inifi Band At the present, when we talk about the concept of cloud computing along with associated ideas that are establishing most of solutions by third party that is interconnected with the internet. At this time, Ethernet is the most commonly used technology. However, a vital trend nowadays is to arrange 10 Gb Ethernet also abbreviated as (10GBE) along with equipment and networks that are useful in enhancing the Ethernet’s capability and capacity towards its support for additional traffic patterns. Where as, Fiber Channel is referred as standard communication protocol which is embedded on most of the hardware and software devices is mostly used in storage area networks (SAN) and scientific computing whereas Inifi Band architecture which is a switched fabric communication link used for high performance in data centers is entirely deployed within engineering models as well as in scientific simulation networks. The best example to define it is clustered servers (Nations, 2011; Ingthorsson, 2010). It is a true fact that there are still advanced networking technologies that are available along with protocols, that are used for sustaining the deliverance of Cloud services. Obviously we can consider this as an ever emerging ecosystem, that needs new-fangled improvements and innovations that will carry on evolving in numerous directions. However, for the service providers and Cloud vendor, it is still, essential to realize the weaknesses along with strengths of networking technologies that are individual and in which useful ways they can efficiently be functional inside their technical infrastructure or in current surroundings, whether it is located within a data center or in the form of transport sphere (Nations, 2011; Ingthorsson, 2010). Business Cases A true fact is that over 90% of the entire processes that are related to corporate sector directly or indirectly are now automated, hence it will result in the stress on CIOs has never been better. As a result a long lasting but increasing load of expectations related to corporate sector is totally based on the IT(information technology) supportive configuration not minimally to offer reliable desktop as well as back office dispensation along with cost competent , but to imitate innovation and agility. Now the trends are a little bit change at managerial level. Consequently, now it’s a race for CIOs to settle the curve, by implementation of those disruptive advance technologies that will carry a competitive frame in addition to a raft of supplementary business profits. Definitely, company or business related workflows are gradually more being formed by the vary technology that introduced to sustain them. In the past ERP (enterprise resource planning) and various other applications have affected many areas resulted improvement in the design of supply chain management. At the present, the ideas related to cloud computing are influencing new horizons of data storage, interaction based environment, management and interconnection between server as well as client and the service models that are managed by them. However we know that aspect like social networking is revolutionizing which tends to communications at corporate level and methodologies that is valuable to us in collaborative working. Meanwhile, now it is not adequate to statute the data centre, organizational heads or CIOs have got to be the pioneers of trends that we will face tomorrow and influential leaders of change management (Michaels, 2011). Business case example: Orange adopted Cloud and Virtualization Management Orange company is one of the major European operators which provide its services in the field of mobile as well as broad band services of internet and in the brand name Orange Business Services which is one of the global influential leaders in providing telecommunication services to local level and multinational organizations. OBS that is also referred as Orange Business Services is a French Telecom branch which is committed to provide B2B services and it is dynamically operational in the cloud management workgroup along with the DMTF (Distributed Management Task Force) to move forward internationally in management standards which relate to cloud and virtualization management in possible means. Hence, standards of cloud computing will permit additional choice for IT clients via portability and interoperability among various cloud frameworks (Dunst, 2011). DMTF (Distributed Management Task Force) enables businesses with more effectual management through which millions of IT systems round the globe by bringing the IT sector mutually to work together on the field of development, promotion and validation of systems that regulate management standards. In this scenario, Orange Business Services (OBS) will facilitate to promote (Open Virtual Format) OVF, a contemporary American Standard. In addition, Orange will support an ISO certification for the new worldwide adopted virtualization standards (Dunst, 2011). Another vital area of focus for Orange Business Services (OBS) is on world wide standardization that is used for a cloud management Application Programming Interface some times abbreviated as (API). Throughout its collaboration with DMTF (Distributed Management Task Force), Orange Business Services will contribute in the formation of a global standard designed for a cloud management communications and infrastructure as a Service (IaaS) API (Dunst, 2011). According to head of cloud services Alex Rigaldo at Orange Business Services, believed that: “this continuous development in effective virtual infrastructure intended for our cloud services that has ambitious to those requirement which indeed useful for a standard management solution techniques. However, a lot of technical solutions are to be engaged that’s why Orange Business Services is looking ahead for working with DMTF. The main goal of Orange Business Services is to construct an easy to use platform for their consumers to access the IT resources on which cloud computing aspects prevailed, they require by providing a one stop shop for a variety of cloud computing services. However, an incorporated advance approach, Orange Business Services can distribute network and IT with end to end service level requirements (Dunst, 2011). A project which can be related to industrial level, “conquests 2015?, Orange company is at the same time addressing its human resources, consumers and shareholders, as well as the culture in which the company operates its functionalities, throughout a existing set of action strategy. Although these commitments are articulated through a new vision of human resources for workers also through the deployment of a network infrastructure through which a company plans its growth as well as in particular to enhanced quality of services provided and through the rushing of international development (Dunst, 2011). Task 2 Virtualization Virtualization is such sort of framework or we can say a methodology which is useful in separating the resources of a computer into numerous execution environments, by applying a single or additional concepts or related technologies which can be defined as a hardware as well as it includes software partitioning, complete or partial machine simulation, time sharing concepts, excellence of service, emulation and a lot of others (Singh, 2004). At the present, virtualization has become the main focus for IT organizations and professionals because virtualization provides them with a lot of benefits that affect many aspects of operations related to information technology and hence it is also valuable in reducing the investment/cost, reduction in the total number of servers that are required to support failure as when virtual server fails also improvement in CPU utilization also it provides us flexibility for the allocation of storage and many other benefits. With all of these benefits, no doubt that IT professional are keenly pursuing this technology development (Christine et al., 2008). Review of Virtualization to Cloud Computing The table given below outlines the comparison of Virtualization and Cloud Computing: (Stratus Technologies, 2010) At the present In future At the present, server virtualization is a growing key trend. Now virtualization solutions are in progress to be launched those results in the emergence of cloud computing solutions. Monitoring as well as Management capabilities are still in developing in versatile ways. Many concerns that relates to, privacy, security in addition to compliance are still to be address for responsive applications and services. In the future, major trend will be cloud computing. Various standards of cloud computing and virtualization will raise the easiness of deployment and also valuable in the reduction of risks. Different possibilities of monitoring and management come of age to decrease requirements required for specialized IT expertise which include programmed policy making and self management. Virtualizations provide a lot of benefits, but also there are advanced concerns that need to be managed. However, it is essential to keep this matter in mind because it is more rapidly to construct virtual servers as compared to specify and to inaugurate/install hardware, moreover, there might be a trend to construct virtual environments “ad hoc” along with virtual environments can possibly become uncontrollable. In this regard, having extra virtual server instances will augment the desired work load for maintaining, patching as well as securing (Christine et al., 2008). Following are important benefits of virtualization: (Christine et al., 2008) It helps to increase desktop life cycle. Users are capable to access their desktops from everyplace, depends on their choice The desktop of a user look the same no issue from where they are accessing their desktop.
