What cloud computing really means. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing. Cloud computing definition, Internet-based computing in which large groups of remote servers are networked so as to allow sharing of data-processing tasks.
3 Intel IT enter Planning uide Virtualization and Cloud Computing The Path to Simplified Delivery of Cloud Services Today the cloud is a proven delivery model, with a. Elcome to Cloud Services For Dummies, IBM Limited Edition. Whether public, private, or hybrid, cloud computing is becoming an increasingly integral part of many. Introduction to Cloud Computing. When you store your photos online instead of on your home computer, or use webmail or a social networking site. Publication provides the definition of cloud computing and associated terminologies for the general users.
Cloud computing - Simple English Wikipedia, the free encyclopedia. In Computer science, cloud computing describes a type of outsourcing of computer services, similar to the way in which electricity supply is outsourced. Users can simply use it. They do not need to worry where the electricity is from, how it is made, or transported. Every month, they pay for what they consumed. The idea behind cloud computing is similar: The user can simply use storage, computing power, or specially crafted development environments, without having to worry how these work internally. Cloud computing is usually Internet- based computing.
The cloud is a metaphor for the Internet based on how the internet is described in computer network diagrams; which means it is an abstraction hiding the complex infrastructure of the internet. For example, Google Apps provides common business applications online that are accessed from a web browser, while the software and data are stored on the Internet servers.
Cloud computing is often confused with other ideas: Many cloud computing deployments are powered by grids, have autonomic characteristics and are billed like utilities, but cloud computing can be seen as a natural next step from the grid- utility model. The services are accessible anywhere in the world, with The Cloud appearing as a single point of access for all the computing needs of consumers.
Commercial offerings need to meet the quality of servicerequirements of customers and typically offer service level agreements. Many cloud computing providers use the utility computing model which is analogous to how traditional public utilities like electricity are consumed, while others are billed on a subscription basis. By sharing consumable and ! Most internet users are currently using cloud services, even if they do not realize it. Webmail for example is a cloud service, as are Facebook and Wikipedia and contact list synchronization and online data backups.
The Cloud. They found the new cloud architecture resulted in significant internal efficiency improvements. It was a hot topic by mid- 2. This dates back to the early days of the Internet, where libertarian thinkers felt that . According to the AGPL license application service providers are required to release any changes they make to an AGPL open source code.
Cloud architecture. It typically involves multiple cloud components communicating with each other over application programming interfaces (usually web services). Complexity is controlled and the resulting systems are more manageable than their monolithic counterparts. Cloud architecture extends to the client where web browsers and/or software applications are used to access cloud applications. Cloud storage architecture is loosely coupled where metadata operations are centralized enabling the data nodes to scale into the hundreds, each independently delivering data to applications or users.
Capital expenditure minimized, therefore low barrier to entry as infrastructure is owned by the provider and does not need to be purchased for one- time or infrequent intensive computing tasks. Services are typically being available to or specifically targeting retail consumers and small businesses. Device and location independence.
Massive scalability and large user bases are common but not an absolute requirement. Security which typically improves due to centralization of data, increased security- focused resources, etc. Accesses are typically logged but accessing the audit logs themselves can be difficult or impossible. Sustainability through improved resource utilisation, more efficient systems and carbon neutrality. For example: A cloud client is computer hardware and/or computer software which relies on The Cloud for application delivery, or which is specifically designed for delivery of cloud services, and which is in either case essentially useless without a Cloud. Infrastructure as a service) is the delivery of computerinfrastructure (typically a platform virtualization environment) as a service. Platform as a service) (the delivery of a computing platform and/or solution stackas a service) .
Software plus services) or end users directly. Symantec's Online Storage for Backup Exec). Others focus on providing a new kind of back- end storage optimally designed for delivering cloud storage (EMC's Atmos), categorically known as Cloud Optimized Storage. A cloud computing provider or cloud computing service provider owns and operates cloud computing systems serve someone else. Usually this needs building and managing new data centers. Some organisations get some of the benefits of cloud computing by becoming . The barrier to entry is also significantly higher with capital expenditure required and billing and management creates some overhead.
However, significant operational efficiency and quickness advantages can be achieved even by small organizations, and server consolidation and virtualization rollouts are already in progress. This allowed small, fast- moving groups to add new features faster and easier, and they went on to open it up to outsiders as Amazon Web Services in 2.
