What Is Cloud Computing And Distributed Systems?

Cloud computing is innovative which uses well advanced computational power resource and gigantic improvement in storage capabilities, Cloud is the long dreamed vision of computing utilities, which helps in enable ling the sharing of

Cloud Computing has been a buzz world in the past few years. The use of this technology increased considerably when we made huge progress in this domain, reducing the cost for everyone. Today, Cloud Computing is widely used all across the world by a lot of companies such as Microsoft, Facebook, Amazon, etc…

Cloud computing is a new paradigm in the computer virtualization. It has transformed the technology and business and its use is growing rapidly. Unlike traditional system, where services are hosted at physical location, cloud computing offers a virtualized shared machine in a web based environment. Cloud computing has three types of service models and four

In computing, cloud computing and as a sub component, cloud storage is a term used to describe a large number of computers or a few very large servers connected to each other through some form of network usually a wide area network or internet link, this network is sometimes referred to as an internet area network. The evolution of cloud computing started by the original concept in the 1950’s of large servers which were accessible from terminals with no real processing capacity themselves which would allow for multiple parties to share its resources with the connected terminals and allow for more CPU uptime. This meant that the servers which may have cost thousands of pounds or were only available for research use would be much more

Several years after the emergence of cloud computing, most of people still confuse with its concept because different research institutes defined the term differently. With the development of cloud computing, its concept evolves gradually in years. According to the Wikipedia, the most recent definition of cloud computing is “the delivery of services of the computing a service rather than a product, whereby shared resources, software, and information are provided to computers and other devices as a utility over a network (typically the Internet).” Cloud computing, in one word, was termed as the many different types of virtualized applications and services that are moved into the “cloud” – a metaphor for the internet. Cloud computing providers maintain and control physical servers, and data is processed in the “cloud” provider’s environment which also delivers hosted services. For the user, the entire computing infrastructures virtually reside “in the cloud.” In many cases, devices that used to access these services and

Since more than one client may access the same data simultaneously there should be a mechanism to keep the data updated . Distributed file systems typically use file or database replication (distributing copies of data on multiple servers) to protect against data access failures.

When using ordinary computing, we install software programs on computer and update the hardware as per our requirements. Documents we create or save are stored in our computer. Documents are accessible on our own network, but they can’t be accessed by computers outside the network. Cloud computing, the software programs aren’t run from one’s personal computer, but are rather stored on servers accessed via the Internet. Cloud Computing provides resources and capabilities of Information Technology such as SaaS (Software as a Service), PaaS (Platform as a Service), IaaS (Infrastructure as a Service),HaaS (Hardware as a Service) to distribute the powerful computing capacity to end-users. However, still there exist many problems in cloud computing today, the current researchers or practitioners pointing that data security and privacy risks have become the

Cloud computing is a computing model which is widely applied and is one of the most recent terms in the computing industry. The cloud allows for outsourcing of computing infrastructures for storing data and applications of which are remotely accessible by a server. Cloud computing can be referred to network-based hosting of programs in a way that users are not expected to update software/hardware or purchase updated versions. Clouds allow on-demand delivery of software, hardware and data services. Cloud services can be dynamically scaled to meet the needs of its users and are designed to provide easy and scalable access to additional applications (Almutairi, Sarfraz and Ghafoor, 2015). However, the security challenges in cloud computing

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

A cloud is a type of parallel and distributed system consisting of a collection of inter-connected and virtualized computers that are dynamically provisioned and presented as one or more unified computing resource(s) based on service-level agreements established through negotiation between the service provider and consumers. The term ‘cloud’ first referred mainly to large ATM networks. Cloud computing began in earnest with the advent of Amazon’s web-based services. Yahoo, Google, IBM, Microsoft, Sun, Intel, Oracle, SAS, and Adobe followed to offer cloud computing technologies.

Infrastructure as a Service like Amazon Web services provides virtual server instances with unique IP addresses and blocks of storage on demand. Customers use the providers application program interface(API) to start, stop, access and configure their virtual servers and storage. In the enterprise, cloud computing allows a company to pay for only as much capacity as needed and bring as soon as more is required.

The cloud, or cloud computing (basically internet computing), is a net based resource that allows sharing computer resources without the need of local servers.[2] Not only does it not make use of local

Cloud computing is type of internet-based computing network in which many remote servers are   allowed to the centralized data storage, and online access to computer services or resources.

The cloud is a data storage method that stores information on the iInternet rather than in a secure facility. Cloud data revolutionized the way companies store their information by making it easier to organize files from any location —, not just the office desktop. Suddenly CEO’s could work from Bermuda, having access to every file on the go.

“Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model is composed of five essential characteristics, three service models, and four deployment models.”
