Fog Computing Of Smart City Essay

Edge computing confines data processing of IoT/big data applications to local servers on the network edge so as to reduce network bandwidth consumption. In the process, it reduces latency by offloading some of the computation-intensive work that was supposed to be done entirely on the cloud

Cloud computing is a fast growing information technology trend that many companies including Google, Microsoft, and IBM are currently looking to get a stake in as demand for the service grows. Cloud computing is the concept of allowing both individuals and businesses to store data and applications on remote servers (owned and operated by a third party company), rather than on their own hard drives and data centers. The service boasts the ability to securely access data and applications from just about any device with an internet connection, allowing for such services as streaming music from a personal collection from multiple devices, and even to business

In his article “Online 24/7: ‘Life Logging’ Pioneer Clarifies the Future of Cloud Computing”, Larry Greenemeier (2011) describes the idea of cloud technology, where it stands today and where we are heading to. According to Greenemeier’s article, the idea of cloud computing is to make all the information and services available via web. It will enable access to data and apps without the need for a lot of storage or processing power on the devices themselves.

Cloud because of its wide range of applications it allows users to store data their data remotely in the cloud and enjoy the on-demand high quality cloud applications and reveal burden from the local storage, cost and maintenance. In this according to the user’s perspective, including both individuals (private) and enterprises like companies appealing the cloud benefits by storing data remotely into the cloud in a flexible on-demand manner and relief of the burden of storage management along with this he/she can also enjoy the universal data access which dependent geographical locations and avoidance of the capital expenditure, software, hardware and personnel management and maintenances and so on.

Cloud computing is an emerging model where users can gain access to their applications from anywhere through their connected devices. A simplified user interface makes the infrastructure supporting the applications transparent to users. The applications reside in massively-scalable data centers where compute resources can be dynamically provisioned and shared to achieve significant economies of scale. A strong service management platform results in near-zero incremental management costs when more IT resources are added to the cloud. The proliferation of smart mobile devices, high speed wireless connectivity, and rich browser-based Web 2.0 interfaces has made the network-based cloud computing model not only practical but

One local layer that performs a preprocessing of data and later replicates them to a layer that is centralized in the cloud. Although the proposed address addresses a relevant problem in the IoT area, the work does not address the persistence of data at the edge of the network, considering the dynamic environment of Mist computing.

Capacity is a central concept in fog and cloud computing. Keeping in view the large amount of data being produced, it is important to enhance storage and data management technologies. A great deal of research and development is being done on these technologies by technology companies in developed regions. It has been determined that capacity is a two-fold construct. It includes network

Cloud computing emerge as a computational prototype as well as a sharing architecture and its main intention is to provide secure, quick, convenient data storage and net computing services and dispatched all

Until 2008, internet had been represented on network diagram by a cloud symbol. Later variety of new services started to appear and permitted computing resources to be accessed over internet termed cloud computing. Cloud computing encloses activities like the use of social networking sites as well as other forms of interpersonal computing ; however most of the time cloud computing related with accessing online software applications, data storage and processing power. Clouding computing can

Cloud Computing has been one of the greatest concepts of computer access over the last years, but in fact we have been using it for more than ten years and the majority of us takes advantage of this technology in our daily life without realize it. Gmail, Dropox, Facebook, and many social networks are all examples of Cloud Computing solutions. It seems that the Cloud computing has become essential to a generation that is in constant battle to reduce costs and in the same time to provide unlimited access of advanced technology and great capacity of data processing without the need of huge investments.

Cloud computing is a topic of which much is assumed. The average person recognizes the term “cloud computing” as having to do with their storage from their iPad or iPhone on the online storage area which syncs their Apple devices to their computer. This common cloud is called the iCloud. That is where common knowledge ends about this topic. However, upon further exploration, a deeper understanding is gained with greater explanation, and it is realized that cloud computing is something that is used all of the time on many levels of everyday technology. While the terminology remains cryptic to the mind of most people, the concepts behind the practical uses of cloud computing become quite clear. It is relatable and understandable. Upon this revelation, the iCloud is recognized as the tip of the preverbal iceberg when speaking about cloud computing. It is important to discuss and further understand the many types of cloud computing as well as the various applications to life through technology. This affects how information is stored online, computers are protected, information is secured, emails are processed, and many other factors that are taken for granted in the world of technology. Cloud computing is a general term used to describe how information is stored, utilized, and accessed over the internet. There is no cloud, but the word cloud gives the connotation of an abstract place which is known to exist but is too vast to touch or contain (Griffith,

In this way, mobile computing has brought some major changes to the internet world; some of them include cloud computing, social media services and e-commerce. Cloud computing is a service through which users can compute data, use applications and save their data online on internet. This stored data and applications can be accessed anywhere anytime. For example, if a user saves some data online in cloud from home desktop and then finds a need to access while being on a trip, it can be easily accessed through mobile phone or laptop just by connecting to internet. Similarly, applications can be used while being mobile.

Cloud as the term signifies means the computers in a network to be used for data storage remotely and for maintenance. The cloud computing offers reductions in costs and also has increased scalability, reliability and flexibility in its own processes, and is considered as todays one of the most exciting technologies and has seen a rapid growth over the past ten years. The Cloud computing uses advanced level of computational

The use of IoT has already impacted the way cities operate. The term smart cities, is used to describe a city that possesses an IoT oriented infrastructure. “In a smart city, the digital technologies translate into better public services for inhabitants and better use of resources while reducing environmental impacts”. [3] For a smart city to be feasible, IoT must provide intelligence, interconnection, and instrumentation. Wi-Fi-enabled smart devices and low-cost sensors are components of the smart city and allow devices a way to communicate with the public via the internet. These devices collect real-time data, which not only improves the lives of residents, but transforms several sectors of public service as well. Transportation has been revolutionized by smart traffic management systems which gather data from an array of magnetic road sensors and hundreds of cameras. The result is less delay at major stop lights and increased travel speeds, because enabled drivers can see which lights are busy and monitor these areas for other vehicles and pedestrians. To lower traffic and driver search times for parking spots, parking sensors that detect parking-spaces for drivers are installed in major cities. Street lights use a method of energy saving known as adaptive lighting which enables them to determine their brightness setting, appropriate for a given situation. The smart city solution to conserving energy is through smart girds. A smart grid serves several energy management

Shifts the “Flow of Data”: Existing Cloud Computing paradigm promotes a more innards data flow and processing model that’s mostly unidirectional. Fog changes the way data flows in and out of the cloud and what role each layer focuses on. Fog provides the data element analysis at the Edge while the cloud will play a more post-data-cleansing role. Fig XX best describes this below.
