Cloud Computing And Its Features (P1)

From the definition of cloud computing we can see 5 most significant features of the cloud:

Self-service capability

"Consumers may unilaterally set the resource requirements to meet the requirements of the system such as: using Server time, storage capacity, as well as the ability to meet the system's largest interaction to outside."

Users can use the cloud services - at the level of infrastructure, platform, or application - whenever they want, without the significant support.

Typically, these services must pay. Buyers can set up an account with the sellers, establishing security and billing information, and then select and organize the use of cloud computing resources are sold. This is typically done by using an easy and friendly online system. In the case of IaaS, for example, this can allow users to start virtual machines, assign network addresses, store and distribute.

In some cases, especially with the private cloud, the payment is not necessary. The service providers will give consumers the ability to configure resources and their history.

For suppliers, self-service on-demand procurement of hardware requirements, account management, service notes, security control, service management, bandwidth, payment and liquidation mechanisms shall be established. These mechanisms will communicate with the operating system for the services to be provided, start, and stop under the guidance of consumers. Users can use a service that lasts a few minutes, or  weeks, months or even years.

Although the concept of cloud computing gives the illusion of infinite resources, but it is clear that in reality it does not exist, and certainly does not exist when all users use it at the same time. How to forecast the demand of services, and how to provide effective services, are the foundation for providers to meet the expected needs of the users for the best services.

The providers often place restrictions on the use of their services in line with the affordability of the users. The providers can allow users to use applications, services and resources on the cloud along with the infrastructure at minimum cost or use the additional payment method to maintain the services. Financing methods can be applied to help users get better services such as discount policy for long-term prepaid customers.

Broad Network Access - wide connectivity.

"With the ability of resources are available on the network and can be accessed through many different devices from phones, tablets, laptops and can run on many different platforms."

Network access is needed to establish the relationship of supplier/customer, to use the next cloud services themselves, and to use the value-added services that consumers can do by using cloud computing services. For example, a company can use cloud computing services to make a website to provide product information. Companies need access to the network to buy and configure cloud services, to manage and operate their website, and their customers need access to the network to use the site.

People who are using cloud services or additional services can have a computer or a device such as a tablet, or mobile phone, ... This may have either browsers. Or cloud computing services can be integrated into an IT architecture of consumers’ enterprise, with access from huge and complex computer systems.

The cloud service must be accessed through a standardized mechanism. This mechanism is carefully considered when deploying services for cloud computing. If you fail to comply with these standards throughout the service, the ability to access services from devices and applications will definitely be reduced and network access will not be possible.

Generally trading companies want maximum market access. The use of cloud computing services allows their services access to more customers and the sale potentials also increases.
