  BUSINESS AND CONSUMER APPLICATIONS  Cloud computing innovations are likely to help the commercial and consumer sectors the most. On the one hand, the ability to convert capital expenses into operating costs makes clouds an appealing alternative for any IT-centric business. On the other hand, the cloud's feeling of ubiquity in terms of accessing data and services makes it appealing to end-users. Furthermore, because cloud technologies are elastic, they do not necessitate large upfront investments, allowing innovative ideas to be easily converted into products and services that can readily scale with demand.

 Architecture of Cloud computing Cloud computing is utility-oriented and Internet Centric way of delivering IT services on demand. cloud computing architecture includes  i) infrastructure as a service i)platform as service  iii) software as a service From the figure above, we will discuss i) infrastructure as a service ii)platform as service iii) software as a service  iv) user-level middleware v) User application  vi) core middleware vii) system infrastructure. 1. IAAS It provides access to fundamental resources such as physical machines, virtual machines, virtual storage, etc. Characteristics: virtual machines with pre-install s/w virtual machines with preinstall os  on-demand availability of resources Allow copying of the particular data at different locations. resources can be easily scaled up and down. 2. PAAS :  platform as a service offers the runtime environment for the application. It offers development and deployment tools Required to develop the application. characteristics:

  Media Applications The use of cloud computing technology can benefit media applications as well. Encoding, transcoding composition, and rendering are examples of video processing tasks that are well suited to a cloud environment. These are computationally expensive jobs that can readily be transferred to cloud computing infrastructures. Examples Animoto, Maya rendering with Aneka, Video encoding on the cloud: Encoding.com, Multiplayer online gaming, etc.

The most important advantage of cloud technologies for social networking applications With over 1 billion members, Facebook is perhaps the most visible and intriguing social networking platform. To keep up with this enormous expansion, Facebook has needed to be able to expand capacity and build new scalable technologies and software systems while retaining high speed to provide a seamless user experience. Multiple data centers are required to support systems with a large number of users. They require highly efficient infrastructure. In the case of Facebook, such a platform largely supports the system's major functionality while also providing APIs for integrating third-party apps - such - as social games and quizzes made by others. LAMP is the foundation of the basic reference stack that serves Facebook (Linux, Apache, MySQL, and PHP). This set of technologies is complemented by a suite of additional in-house services. These services are written in several languages and include fea

  CRM and ERP CRM (customer relationship management) and ERP (enterprise resource planning) systems are two industry categories that are thriving in the cloud, with CRM being the more mature of the two. Cloud CRM programs provide small businesses and start-ups with a terrific way to get fully working CRM software without big upfront expenditures and by paying monthly fees. Furthermore, CRM is not a task that needs a certain set of requirements, and it can be readily migrated to the cloud. Cloud CRM software has grown in popularity as a result of this feature, as well as the ability to view your business and customer data from anywhere and on any device. Cloud-based ERP systems are less mature, and they must compete with well-established in-house solutions. Finance and accounting, human resources, manufacturing, supply chain management, project management, and CRM are all integrated into ERP systems. Their purpose is to give a unified perspective and access to all activities required t

   GEOSCIENCE: SATELLITE IMAGE PROCESSING  Massive volumes of geographic and non-spatial data are collected, produced, and analyzed by geoscience applications. The volume of data that has to be processed grows considerably as technology advances and our world gets increasingly instrumented (e.g., through the deployment of sensors and satellites for monitoring). A fundamental component of geoscience applications is the geographic information system (GIS). All sorts of spatially linked data may be captured, stored, manipulated, analyzed, managed, and presented using GIS applications. This sort of data is becoming increasingly important in a range of application sectors, ranging from advanced agriculture to civic security and natural resource management. As a result, large amounts of geo-referenced data are fed into computer systems for processing and analysis. Cloud computing is a compelling alternative for completing these time-consuming processes and collecting useful data to aid decis

  Healthcare: ECG (Electrocardiogram) Analysis in cloud computing Healthcare is a field, subject, sector, or territory in which information technology has several uses. These apps are being used to aid businesses in supporting scientists in developing disease prevention solutions. Cloud computing has emerged as an appealing alternative for constructing health monitoring systems as a result of the development of the Internet or to put it another way, as a result of the availability of the internet. The ECG machine, for example, is a health monitoring device that measures the human body's heartbeat and prints the results on graph paper. The electrocardiogram (ECG) measures the electrical activity of the heart's Cardium. A waveform is created as a result of this action, which is repeated throughout time and symbolizes the heartbeat.  The analysis of the shape is used to identify arrhythmias, and it is the most common way of detecting heart diseases. Here the meaning of arrhythmias
