Operating System Cloud Computing : Mechanisms, Issues And Implementation

Cloud computing can be understood as a multifaceted infrastructure of hardware, software, storage and processing available to be used as a service. With the use of cloud computing, without even knowing how it works, one can access a large number of the most sophisticated supercomputers of the world and their respective processing powers without being overwhelmed with space or information. Cloud computing allows access to computer networks located at various places in the world and thus offers the speed of

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.

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

This section of the article describes cloud computing as a group of computer systems connected over a public or private network that provides dynamically scalable infrastructure (equipment and software) for application, data and file storage. This means that the cloud can be easily modified to add or remove resources and infrastructure as needed. In continuing with the overview, the article notes that cloud computing is an innovative approach to traditional computing methods that can be utilized through the different cloud models.

IT departments and infrastructure providers are under increasing pressure to provide computing infrastructure at the lowest possible cost. In order to do this, the concepts of resource pooling, virtualization, dynamic provisioning, utility and commodity computing must be leveraged to create a public or private cloud that meets these needs. Cloud computing is a general term for anything that involves delivering hosted services over the Internet. This provides the smaller

Cloud computing has evolved with the passage of time and has revolutionized the entire ICT industry. Cloud computing is categorized into two forms Service oriented computing and Grid Computing. Service oriented Computing is an transpiring paradigm that has revamped the consumption of software and related product all around the globe. The core functionalities that service oriented computing provide is elements and that are independent of platforms and are programmed using standard protocols to support distributed computing across various organizations.

With the growing of technology and people around the world using the internet more often, the cloud is becoming more popular than ever before. The United States National Institute of Standards and Technology has defined cloud computing as follows: "Cloud computing is a model for enabling 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 [1]." There are many uses of the cloud but the main uses people use the cloud for is to host websites, store documents, and to stream TV shows and movies. With all this new flooding of the cloud computing network, the dependability of cloud computing systems have come into question for all cloud service providers, consumers, and brokers around the world. Fig. 1 is just one example of the growth of cloud computing of a single company.

Cloud is a trending term across the Internet and is often confused with data center and virtualization. To begin with, data center and virtualization are centric to the cloud, but scope of the cloud as a whole is much wider. To put in simple words, a cloud is a pool of large configurable resources that are available on demand over the Internet. These resources can be available in the form of storage devices, servers, processors, and network interfaces [4]. Packaging these resources to provide services to end-users is termed as cloud computing. The users are provided with an ease of accessibility

The data being shared among the open space is less secured. Cloud computing involving different technologies like networks, databases, operating systems and many other, has enormous security issues. In perspective to the designing of a distributed operating systems that support cloud computing, resource scheduling, transaction management, load balancing, concurrency control, memory management are some of the major issues that are to be considered. Scalability, loss of data, performance also stand as the other major concerns due to the heavy growth of organizations which are using the cloud.

Cloud computing is the new buzz in the recent days and cloud computing allows users to share files and applications over the internet. In the following pages we will discuss about the cloud computing its pros and cons, the security risk and how to overcome and use its resources for the best advantage of organizations. It is attracting much of the attention now-a-days which can be seen by observing the big names of the IT industry like IBM, Microsoft and Google investing millions of dollars into research on cloud computing.

The largest Buzzword in emerging trends for the computer world is “Cloud”. Cloud computing in the future for data, services and platform. The concept of cloud computing is to make whatever aspect it is being used in available at all times and to act as a resource. Turning computing into a utility will transform how the IT industry uses services, designs hardware and uses network infrastructures. The term “Cloud” however has many meanings, but understanding what exactly is meant by cloud computing is the first step to

Cloud computing is one of the biggest innovations of the 21st Century. Moving into 2014, cloud computing remains a big IT trend. It is a broad term that covers any type of computing or storage service that is delivered to users from remote servers. This mode of service has technically been in place for years, with online email services being one common example. As technology has progressed, a variety of services can now be provided from the cloud, such as file storage and the ability to run an entire program without having them installed on your computer. Cloud computing allows for pay-per-use or charge-per-use access to applications, software development and deployment environments, and computing infrastructure. Furthermore, it

“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.

The term we know today as “cloud computing” was derived from this broad representation of the Internet. In its simplest definition, cloud computing describes a colony of web-based computers, resources, and services. Software and system developers can utilize these web-based resources to provide a broader range of products to their consumers. The resources in the cloud are most often thought of as virtual assets. This means that if a system or an application needs more computing power or disk space, these cloud resources can be added on-demand in a transparent manner.

Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computer resources (e.g., networks, servers, storage, applications and services) tha can be rapidly provisioned and released with minimal management effort or service provider interaction. Five essential characteristics of cloud computing: on-demand self-service, broad network access, resource pooling, rapid elasticity or expansion, and measured service. Three service models (software,
