A Brief Introduction To Cloud Computing

Introduction:

Cloud computing can offer as to provide a service where the software, shared resources and other information directly or indirectly associated peripheral rather than a product or device can be defined. 

The architecture of cloud computingcan be described as three basic units: the implementation of the platform and infrastructure constraints on the number of residents that can be accessed from any computing device to the Internet. Cloud computing provides an environment where the user of the computer without prior knowledge of the physical location and configuration of the system can be operated on services provided by servers access.

Cloud computing is a model of services on Internet protocols that the user based on shared resources with pre-installed browsers on their computers or mobile devices Access Help. It also includes the areas of business that the data is stored on servers and users to remotely access, depending on the type of business authenticated.
Cloud Computing shares characteristics with the following environments:
- Mainframe
- Gird Computing
- Autonomic Computing
- Peer-to-peer
- Client-Server Model
- Utility Computing 

Cloud layers:
Anwendungen -> Platform -> Infrastruktur -> Server->Client -> Applications -> Platform -> Infrastructure -> Server
Client: A client can be viewed as an end user, with the help of a hardware or software that use cloud computing environment for the deployment of applications.
Application: It is "Software as a Service (SaaS)" to customers for the direct use of the Internet to be delivered to the correct installation before running an application.
Platform: Provides an online platform or a number of solutions as a "Platform as a Service (PaaS)", which facilitates the delivery of services, at no cost and complexity and improving sustainability in the workflow known.

Infrastructure: Also known as "Infrastructure as a Service (IaaS)" provides a known virtual infrastructure with full access to the Internet application using the data needed, and access the network without all the assets and the outsourcing buy it directly.
Server: Servers are high-speed software or hardware to provide efficient services. Multi-core processors and super fast delivery services and is operating system specific.
 

Areas of practical application of cloud computing:
The first application and the best of cloud computing is the backup and restore. To invest any more in the use of duplication of backup such as cloud computing in a position greater user friendliness.
The second use as a SaaS application is responsible for the removal of the installation of the application, commonly used for payroll services and Customer Relationship Management is used.
The third thing is that every company is not able to have their own servers or other similar resources. Cloud Computing to share online resources.
 

Possible problems with cloud computing:
In the sharing of resources and data storage on the host system, there are privacy issues. The host must be faithful and be a legal protocol between the host and the client company to security problems that future conflicts can be avoided to avoid be defined.
