Cloud Computing : Cloud Technology

The national Institute of Standards and Technology under the department of Commerce defines Cloud Computing as “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”. Another definition for cloud computing is a term used to describe a network of computers that deliver information technology

Usage of remote servers via internet to store, manage and process data instead of using a personal computer is known as Cloud computing. It’s a set of Information Technology services with the ability to scale up or down their service requirements. Most of the cloud services are provided by a third party service provider. In cloud computing, organizations can utilize IT services without in advance investment. Despite its benefits obtained from the cloud computing, the organizations are slow in accepting it due to security issues and challenges. Security is one of the major problems which hinder the growth of cloud. It’s not wise to handing over the important data to another company; such that clients need to be vigilant in understanding the risks of data infringement in this new environment. This paper discusses a detailed analysis of the cloud computing security issues and challenges. (Ayoleke)

Cloud computing is a practice of storing, collecting and sharing data and resources through web-based tools. It connects many computers together and forms a bigger computer. The biggest characteristic of cloud technology is flexibility. This refers to the ability of system adapting and scale to change in workload. Cloud computing can automatically provision and deprovision information to ensure it satisfies the latest resource demands (Interoute, What is Cloud Computing).

Cloud computing is an internet based computing which provides various applications and services like storage, servers, infrastructure, networking with low cost, on-demand self service, pay as you go model, location independent resource pooling, reasonable price , rapid elasticity etc. Cloud computing is one way to increase the capacity add capabilities without investing in new infrastructures like computer hardware involves storage memory, licensing for new software, training for a person and in a dynamic way.

Public cloud: Is an infrastructure that is open for use by the general public. This type of cloud is owned, managed and operated by a cloud service provider and runs on the provider 's

Cloud computing allows a user to store and access data and programs over the internet instead on their computer hardware (Griffith, 2015). The user is then able to access from anywhere or any internet-enabled device. There are three categories of service in cloud computing: SaaS stands for Software as a Service; IaaS is Infrastructure as a Service; and PaaS is Platform as a Service. Until recently, most users stored and accessed their programs via their hard drive, also known as local storage. What began as an alternative delivery system is swiftly becoming a way for Enterprises to reduce their IT spending while still providing multiple applications to various users. If a service has the following

Cloud Computing is an advanced paradigm with a lot of advantages, but its distinct features also create privacy and security issues. Cloud computing provides service model which is more efficient technology for business support. Cloud computing is in fact a service based approach which has changed almost every aspect of computing technologies. There are many threats to the cloud computing including security vulnerabilities and privacy issues.

What is Cloud computing? Cloud computing refers to the practice of using software and hardware resources at remote location using internet. Thus cloud computing enables user to rely on such resources on a cloud for processing and storage needs and pay as per usage. One of the most important

1. Introduction The definition of Cloud Computing as issued by the U.S. National Institute of Standards and Technology (NIST) September, 2011 is: “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.” Cloud computing is a type of Internet-based computing that provides shared computer processing resources and data to computers and other devices on demand. It provides an easy and flexible way of storing, retrieving huge data without bothering about the resources. With

Cloud computing security is a set of control based technologies and policies that must follow certain rules in order to protect applications, data and any information associated with cloud computing. It is known to provide excellent services but is still not supported by organizations due to privacy issues that includes security and privacy protection. As they obstruct the managers as well as the

Security Issues : There are many challenges in the area of cloud computing and security is one of them. Increasing the level of security is required for improving the quality of cloud based services. Location of data is a important factor in the security of cloud based computing. Transparency of the data location provides the flexibility for cloud based computing, but this is also a threat related to security. For cloud users, to maintain their personal data is a major issue related to cloud computing security. Technical security and policies for cloud users plays a vital role in the cloud security. To build trust and establish it for customers who want to use cloud services, is another issue related to the cloud based computing. Security attacks is another issue related

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.

Community Clouds - Community clouds recently have begun tracking in IT industry and are shared among several companies with similar cloud requirements and concerns. This type of clouds is useful for organisations that need to share same data.

Cloud computing is a general term used to describe a new class of network based computing that takes place over the internet, this is a step up from utility computing (which is a collection or a group of integrated and networked hardware, software on a platform).

1.Cloud Computing: Cloud computing is defined as the different services such as service, storage and applications are deliver to organization devices and computers through internet. There are mainly three types of clouds they are private public and hybrid and three services are offered by the cloud mainly Software as a service in which user rent access to software application functionally over the internet eg:ltu student mails .,
