It is a technology that uses remote servers on the internet to store, manage, and access data online rather than local drives. The data can be anything such as files, images, documents, audio, video, and more. Cloud computing is a virtualization-based technology that allows us to create, configure, and customize applications via an internet connection. The cloud technology includes a development University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) What is cloud cloud is the Internet—more specifically, it's all of the things you can access remotely over the Internet. When something is in the cloud, it means it's stored on Internet servers instead of your computer's hard drive. The word "cloud" often refers to the Internet, which more precisely means a datacenter full of servers connected to the Internet performing a service. However, the term "cloud computing" refers to the software and services that have enabled the Internet to become so prominent in everyday life University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) operations that we can do using cloud computing Developing new applications and services Storage, back up, and recovery of data Hosting blogs and websites Delivery of software on demand Analysis of data Streaming videos and audios University Institute of Engineering (UIE)  Department of Computer and Communication Engineering (CCE) Why Cloud Computing? Small as well as large IT companies, follow the traditional methods to provide the IT infrastructure. That means for any IT company, we need a Server Room that is the basic need of IT companies. In that server room, there should be a database server, mail server, networking, firewalls, routers, modem, switches, QPS (Query Per Second means how much queries or load will be handled by the server), configurable system, high net speed, and the maintenance engineers. To establish such IT infrastructure, we need to spend lots of money. To overcome all these problems and to reduce the IT infrastructure cost, Cloud Computing comes into existence. 5 University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Cloud computing University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) History of Cloud Computing Before emerging the cloud computing, there was Client/Server computing which is basically a centralized storage in which all the software applications, all the data and all the controls are resided on the server side. At around in 1961, John MacCharty suggested in a speech at MIT that computing can be sold like a utility, just like a water or electricity. In 1999, Salesforce.com started delivering of applications to users using a simple website. The applications were delivered to enterprises over the Internet, and this way the dream of computing sold as utility were true. In 2002, Amazon started Amazon Web Services, providing services like storage, computation and even human intelligence. However, only starting with the launch of the Elastic Compute Cloud in 2006 a truly commercial service open to everybody existed. In 2009, Google Apps also started to provide cloud computing enterprise applications.

It shares resources among users and works very fast. 2) High availability and reliability The availability of servers is high and more reliable because the chances of infrastructure failure are minimum. 3) High Scalability Cloud offers "on-demand" provisioning of resources on a large scale, without having engineers for peak loads. 4) Multi-Sharing With the help of cloud computing, multiple users and applications can work more efficiently with cost reductions by sharing common infrastructure. University Institute of Engineering (UIE)  Department of Computer and Communication Engineering (CCE) Characteristics of Cloud Computing 5) Device and Location Independence Cloud computing enables the users to access systems using a web browser regardless of their location or what device they use e.g. PC, mobile phone, etc. As infrastructure is off-site (typically provided by a third-party) and accessed via the Internet, users can connect from anywhere. 6) Maintenance Maintenance of cloud computing applications is easier, since they do not need to be installed on each user's computer and can be accessed from different places. So, it reduces the cost also. 7) Low Cost By using cloud computing, the cost will be reduced because to take the services of cloud computing, IT company need not to set its own infrastructure and pay-as-per usage of resources. 8) Services in the pay-per-use mode Application Programming Interfaces (APIs) are provided to the users so that they can access services on the cloud by using these APIs and pay the charges as per the usage of services. University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Applications of Cloud Computing in real-world: Online Data Storage: Cloud computing allows storing data like files, images, audios, and videos, etc on the cloud storage. The organization need not set physical storage systems to store a huge volume of business data which costs so high nowadays. As they are growing technologically, data generation is also growing with respect to time, and storing that becoming problem. In that situation, Cloud storage is providing this service to store and access data any time as per requirement. Backup and Recovery: Cloud vendors provide security from their side by storing safe to the data as well as providing a backup facility to the data. They offer various recovery application for retrieving the lost data. In the traditional way backup of data is a very complex problem and also it is very difficult sometimes impossible to recover the lost data. But cloud computing has made backup and recovery applications very easy where there is no fear of running out of backup media or loss of data. 11 University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Applications of Cloud Computing in real- world: Big Data Analysis: We know the volume of big data is so high where storing that in traditional data management system for an organization is impossible. But cloud computing has resolved that problem by allowing the organizations to store their large volume of data in cloud storage without worrying about physical storage. Next comes analyzing the raw data and finding out insights or useful information from it is a big challenge as it requires high-quality tools for data analytics. Cloud computing provides the biggest facility to organizations in terms of storing and analyzing big data. Testing and Development: Setting up the platform for development and finally performing different types of testing to check the readiness of the product before delivery requires different types of IT resources and infrastructure. But Cloud computing provides the easiest approach for development as well as testing even if deployment by using their IT resources with minimal expenses. Organizations find it more helpful as they got scalable and flexible cloud services for product development, testing, and deployment. University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Applications of Cloud Computing in real-world: Anti-Virus Applications :Previously, organizations were installing antivirus software within their system even if we will see we personally also keep antivirus software in our system for safety from outside cyber threats. But nowadays cloud computing provides cloud antivirus software which means the software is stored in the cloud and monitors your system/organization’s system remotely. This antivirus software identifies the security risks and fixes them. Sometimes also they give a feature to download the software. Ecommerce Application: Cloud-based e-commerce allows responding quickly to the opportunities which are emerging. Users respond quickly to the market opportunities as well as the traditional e-commerce responds to the challenges quickly. Cloud-based e-commerce gives a new approach to doing business with the minimum amount as well as minimum time possible. Customer data, product data, and other operational systems are managed in cloud environments. University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Applications of Cloud Computing in real-world: Cloud computing in education: Cloud computing in the education sector brings an unbelievable change in learning by providing e- learning, online distance learning platforms, and student information portals to the students. It is a new trend in education that provides an attractive environment for learning, teaching, experimenting, etc to students, faculty members, and researchers. Everyone associated with the field can connect to the cloud of their organization and access data and information from there. Cloud Computing in Medical Fields: In the medical field also nowadays cloud computing is used for storing and accessing the data as it allows to store data and access it through the internet without worrying about any physical setup. It facilitates easier access and distribution of information among the various medical professional and the individual patients. Similarly, with help of cloud computing offsite buildings and treatment facilities like labs, doctors making emergency house calls and ambulances information, etc can be easily accessed and updated remotely instead of having to wait until they can access a hospital computer. University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Advantages: Easy implementation. Cloud hosting allows business to retain the same applications and business processes without having to deal with the backend technicalities. Readily manageable by the Internet, a cloud infrastructure can be accessed by enterprises easily and quickly. Accessibility. Access your data anywhere, anytime. An Internet cloud infrastructure maximizes enterprise productivity and efficiency by ensuring your application is always accessible. This allows for easy collaboration and sharing among users in multiple locations. No hardware required. Since everything will be hosted in the cloud, a physical storage center is no longer needed. However, a backup could be worth looking into in the event of a disaster that could leave your company's productivity stagnant. University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Advantages: Cost per head. Overhead technology costs are kept at a minimum with cloud hosting services, enabling businesses to use the extra time and resources for improving the company infrastructure. Flexibility for growth. The cloud is easily scalable so companies can add or subtract resources based on their needs. As companies grow, their system will grow with them. Efficient recovery. Cloud computing delivers faster and more accurate retrievals of applications and data. With less downtime, it is the most efficient recovery plan. University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Disadvantages: No longer in control. When moving services to the cloud, you are handing over your data and information. For companies who have an in-house IT staff, they will be unable to handle issues on their own. However, Stratosphere Networks has a 24/7 live help desk that can rectify any problems immediately. May not get all the features. Not all cloud services are the same. Some cloud providers tend to offer limited versions and enable the most popular features only, so you may not receive every feature or customization you want. Before signing up, make sure you know what your cloud service provider offers. Doesn't mean you should do away with servers. You may have fewer servers to handle which means less for your IT staff to handle, but that doesn't mean you can let go of all your servers and staff. While it may seem costly to have data centers and a cloud infrastructure, redundancy is key for backup and recovery. University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) Disadvantages: No Redundancy. A cloud server is not redundant nor is it backed up. As technology may fail here and there, avoid getting burned by purchasing a redundancy plan. Although it is an extra cost, in most cases it will be well worth it. Bandwidth issues. For ideal performance, clients have to plan accordingly and not pack large amounts of servers and storage devices into a small set of data centers University Institute of Engineering (UIE)  Department of Computer Science and Engineering (CSE) References Text books: Buyya, Rajkumar, James Broberg, and Andrzej M.
