Cloud Computing

Cloud Computing describes the provision of computing power, storage space, and executable software over the network without the need to procure local machines or servers and install software packages. With cloud computing, the entire IT infrastructures can be configured as needed. The configuration and use of the cloud computing is based on interfaces and protocols via a browser GUI from any computer. For many commercial products the billing is often per license based on usage.

The National Institutes of Standards and Technology's NIST Definition of Cloud Computing defines various service models and delivery types. Following this widespread quasi-standard, the following service models for cloud computing are defined:


Service models in cloud computing

Software as a Service (SaaS). This service model enables the user to use applications provided by cloud computing providers running on their cloud infrastructure. These can be proprietary software applications or SaaS solutions of common software packages, such as Office365 from Microsoft. The applications are accessed either directly via the browser or via a (downloadable) program interface.

Platform as a Service (PaaS).This cloud computing service model is aimed at developers and development companies or large IT departments at huge groups. The user is provided with a complete development environment as a platform for the development of cloud-based software as a service (SaaS) and web services for portals and intranets. For every application case matching PaaS solutions without setting up IDEs, runtime environments and unnecessary administration can be found here ...

Infrastructure as a Service (IaaS). The cloud computing service provider provides the user with tailored or scalable resources, such as computing power, storage space and networks, on which the customer can install diverse operating systems and applications according to their requirements. In this point, comparable to the acquisition of its own server or data center, but cloud-based and staggered depending on the cloud computing provider usage or time-dependent. This helps to avoid high investments and one-off expenses for expensive hardware. You only pay for the used devices.


Deployment Models for Cloud Computing

  • Private Cloud. The cloud infrastructure is provided exclusively to a single organization (e.g., a corporation) and provides management and customization to various departments and users. The cloud infrastructure may be owned, managed and operated by the organization itself or the cloud provider and may be scaled as needed.

  • Community cloud. The Cloud Infrastructure is provided exclusively to a group of organizations (government agencies, companies, etc.) and may be owned by one or more of the Organization Members or the Provider. The operation and administration can also be operated by one of the parties. If the organization members have the same requirements (e.g. different city authorities), this solution can be used to reduce and distribute costs.

  • Public Cloud. The public cloud provides access to cloud infrastructures for the general public via Internet. Public-cloud
    solutions can be rented, started up and provisioned on a flexible basis, for example after use or consumption (pay-as-you-go), without having to invest in expensive servers or data centers for short-term computing power.

  • Hybrid Cloud. Hybrid Cloud Solution is a combination of private cloud and public cloud elements that meet the needs of the user, combining the ability to connect private cloud solutions through open standards or proprietary solutions.
