Utility computing, or computer utility, is a service provisioning model in which a service provider makes computing resources and infrastructure management available to the customer as needed, and charges them for specific usage rather than a flat rate. Like other types of on-demand computing, the utility model seeks to maximize the efficient use of resources and/or minimize associated costs. Utility is the packaging of system resources, such as computation, storage and services, as a metered service. This model has the advantage of a low or no initial cost to acquire computer resources; instead, resources are essentially rented.
Software as a service is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally hosted. SaaS is also known as on-demand software, web-based software, or web-hosted software.
A virtual appliance is a pre-configured virtual machine image, ready to run on a hypervisor; virtual appliances are a subset of the broader class of software appliances. Installation of a software appliance on a virtual machine and packaging that into an image creates a virtual appliance. Like software appliances, virtual appliances are intended to eliminate the installation, configuration and maintenance costs associated with running complex stacks of software.
Desktop virtualization is a software technology that separates the desktop environment and associated application software from the physical client device that is used to access it.
Cloud storage is a model of computer data storage in which the digital data is stored in logical pools, said to be on "the cloud". The physical storage spans multiple servers, and the physical environment is typically owned and managed by a hosting company. These cloud storage providers are responsible for keeping the data available and accessible, and the physical environment secured, protected, and running. People and organizations buy or lease storage capacity from the providers to store user, organization, or application data.
Platform as a service (PaaS) or application platform as a service (aPaaS) or platform-based service is a category of cloud computing services that allows customers to provision, instantiate, run, and manage a modular bundle comprising a computing platform and one or more applications, without the complexity of building and maintaining the infrastructure typically associated with developing and launching the application(s), and to allow developers to create, develop, and package such software bundles.
The Rackspace Cloud is a set of cloud computing products and services billed on a utility computing basis from the US-based company Rackspace. Offerings include Cloud Storage, virtual private server, load balancers, databases, backup, and monitoring.
Cloud computing is the on-demand availability of computer system resources, especially data storage and computing power, without direct active management by the user. Large clouds often have functions distributed over multiple locations, each of which is a data center. Cloud computing relies on sharing of resources to achieve coherence and typically uses a pay-as-you-go model, which can help in reducing capital expenses but may also lead to unexpected operating expenses for users.
Dynamic Infrastructure is an information technology concept related to the design of data centers, whereby the underlying hardware and software can respond dynamically and more efficiently to changing levels of demand. In other words, data center assets such as storage and processing power can be provisioned to meet surges in user's needs. The concept has also been referred to as Infrastructure 2.0 and Next Generation Data Center.
A message queueing service is a message-oriented middleware or MOM deployed in a compute cloud using software as a service model. Service subscribers access queues and or topics to exchange data using point-to-point or publish and subscribe patterns.
SOASTA, Inc. is an American subsidiary of Akamai Technologies that provides services to test websites and web applications.
A hosted desktop is a product set within the larger cloud-computing sphere generally delivered using a combination of technologies including hardware virtualization and some form of remote connection software, Citrix XenApp or Microsoft Remote Desktop Services being two of the most common. Processing takes place within the provider's datacentre environment with traffic between the datacentre and the client being primarily display updates, mouse movements and keyboard activity.
Techila Distributed Computing Engine is a commercial grid computing software product. It speeds up simulation, analysis and other computational applications by enabling scalability across the IT resources in user's on-premises data center and in the user's own cloud account. Techila Distributed Computing Engine is developed and licensed by Techila Technologies Ltd, a privately held company headquartered in Tampere, Finland. The product is also available as an on-demand solution in Google Cloud Launcher, the online marketplace created and operated by Google. According to IDC, the solution enables organizations to create HPC infrastructure without the major capital investments and operating expenses required by new HPC hardware.
HP Cloud Service Automation is cloud management software from Hewlett Packard Enterprise (HPE) that is used by companies and government agencies to automate the management of cloud-based IT-as-a-service, from order, to provision, and retirement. HP Cloud Service Automation orchestrates the provisioning and deployment of complex IT services such as of databases, middleware, and packaged applications. The software speeds deployment of application-based services across hybrid cloud delivery platforms and traditional IT environments.
A cloud database is a database that typically runs on a cloud computing platform and access to the database is provided as-a-service. There are two common deployment models: users can run databases on the cloud independently, using a virtual machine image, or they can purchase access to a database service, maintained by a cloud database provider. Of the databases available on the cloud, some are SQL-based and some use a NoSQL data model.
HP CloudSystem is a cloud infrastructure from Hewlett Packard Enterprise (HPE) that combines storage, servers, networking and software.
Abiquo Hybrid Cloud Management Platform is a web-based cloud computing software platform developed by Abiquo. Written entirely in Java, it is used to build, integrate and manage public and private clouds in homogeneous environments. Users can deploy and manage servers, storage system and network and virtual devices. It also supports LDAP integration.
HP Cloud was a set of cloud computing services available from Hewlett-Packard that offered public cloud, private cloud, hybrid cloud, managed private cloud and other cloud services. It was the combination of the previous HP Converged Cloud business unit and HP Cloud Services, an OpenStack-based public cloud. It was marketed to enterprise organizations to combine public cloud services with internal IT resources to create hybrid clouds, or a mix of private and public cloud environments, from around 2011 until 2016.
Cloud computing has become a social phenomenon used by most people every day. As with every important social phenomenon there are issues that limit its widespread adoption. In the present scenario, cloud computing is seen as a fast developing area that can instantly supply extensible services by using internet with the help of hardware and software virtualization. The biggest advantage of cloud computing is flexible lease and release of resources as per the requirement of the user. Other benefits encompass betterment in efficiency, compensating the costs in operations. It curtails down the high prices of hardware and software Although, there are numerous benefits of adopting the latest cloud technology still there are privacy issues involved in cloud computing because in the cloud at any time the data can outbreak the service provider and the information is deleted purposely. There are security issues of various kinds related to cloud computing falling into two broader categories: First, the issues related to the cloud security that the cloud providers face. Secondly, the issues related to the cloud security that the customers experience
An elastic cloud is a cloud computing offering that provides variable service levels based on changing needs.
