Cloud computing refers to the storage of data in a remote data center, but also the execution of programs that are not installed on the local computer, but just in the cloud. By this you can also create backup of useful business data and use it in case of emergency.
Technical formulated describes the cloud computing approach, (B. computing capacity data storage, network capability, or even finished, abstracted IT infrastructure software) to provide dynamically adapted to the needs of a network.
From the user’s perspective provided abstracted IT infrastructure seems distant and opaque, as covered by a “cloud”. Offer and use of these services are provided exclusively through defined technical interfaces and protocols. The cloud computing services includes the whole section of IT services which are very beneficial for any business (e.g. as processing power, disk space), platforms and software. The access to the remote system via a network, such as that of the Internet.
In this industrial world there are still lots of companies which have private network and this is called private clouds, where the provision on an internal company intranet done. Lots of businesses believe in sharing of resources which is a very cost effective way, for their business model. While some of the companies are available in the market that assist Social media marketing feature through which they increase the visibility of a desired site.
The following five properties characterize according to the National Institute of Standards and Technology defines a cloud service:
- On-demand self-service: The provisioning of resources (e.g. computing power, storage) runs automatically without interaction with the service provider from.
- Broad Network Access: The Services are available with standard mechanisms over the network and not to a specific client bound.
- Resource pooling: The provider of the resources are in a pool from which can serve many users (multi-tenant model).The user does not know where the resources are located, but they can contract the location, i.e., for. Example, region, country or datacenter set.
4.Rapid Elasticity: The services can be provided quickly and elastically available automatically in some cases. From the user’s perspective, the resources thus appear to be infinite.
5.Measured Services: Resource usage can be monitored and measured and
calculated in accordance also is made available to cloud users.
This definition is the vision of cloud computing again, which should be avoided to see the individual dots to dogma. So z. B. is a ubiquitous availability in private clouds may not sought. According to the Cloud Security Alliance (CSA) has Cloud Computing in addition to the above-mentioned elasticity and self-service the following properties:
- Service-oriented architecture (SOA) is one of the basic prerequisites for cloud computing. The cloud services are usually offered on a so-called REST API.
- In a cloud environment, many users share common resources, therefore multitenant must be.
- Only the paid resources that were actually utilized (pay per use model), where it also flat rate can give models. So this internet marketing is considered best way to market and promote your business globally and with this you can give feedback to customer queries which will further help rebooting a good and long relationship with customers.
