Cloud Computing Considerations

of Cloud Computing Progress has brought us better software at lower prices and pay per use. It also allowed us unlimited capacity resulting from virtualization. In fact for example in the data center Facebook if you remove some machines, the network continues to function through distributed technology that supports it.

One advantage of cloud computing is that companies should not worry about infrastructure or servers or software, nor do they people from their IT departments in the maintenance of this complex web technology. They can devote themselves to what really adds value, the core of their business.

The Cloud removes barriers to growth and innovation as it is scalable (ability to grow, do it very fast and high loads) Elastic (increasing or decreasing demand) and OnDemand (a simple computer with internet connection and a browser is sufficient).

An example of the use of cloud computing: Zynga, the creator of Farmville (one of the most played games in history) available within Facebook. This company has 10,000 virtual machines to serve all its users. With exponential growth of users you imagine what that could mean having to install machines, software and infrastructure to ensure the service?

The solution is clear .... Cloud computing.

Other examples of the use of infrastructure and services are for example IASS Dropbox or Foursquare. They use the Amazon EC2 infrastructure for operation. DO NOT have private datacenters for the operation of their tools as they could not be competitive and could not adjust to demand quickly and effectively enough.
infrastructure leased to Amazon and it suits their needs at all times.

Amazon EC2 is an infrastructure of public and private cloud used by multiple companies to deploy their applications. It costs airtime. This kind of infrastructure are enabling small companies have the infrastructure necessary to launch their projects and focus its focus on innovation and core business.

Examples IASS use are endless. Imagine a company engaged in video or 3D and have huge computing needs for example for rendering. You can rent these cloud infrastructures for such moments that they are not used to make the huge computer work (at night for example)

This leads to another derivative of this technology is its energy efficiency and Green IT as a consideration because you may get to a major energy efficiency and the efficient use of the datacenters. There

public cloud infrastructures and private cloud infrastructure. Sensitive data such as health, financial, etc., must be protected while other processes do not have this level of requirements.

Reza Thus introduced the concept of "cloud hybrid networks with the coexistence of public private cloud.

CLOUD COMPUTING:

IASS - Infrastructure as a Service. Infrastructure as a service. These solutions (computers and storage) based on virtualization platforms that allow payment for the use (consumption) of the same. Allow full scalability on demand service. Example: Amazon EC2

PASS - Platform as a Service. Platform as a service. Often multiple platforms and application servers run applications that allow BB.DD for these platforms,

Examples: Google App Engine, Force.com (Salesforce)

SASS - Software as a Service - Software as a service. These applications over the Internet. It eliminates the need to install and run applications on the client computer. Examples: social networks, google apps, Salesforce, Oracle CRM OnDemand and numerous free applications that are part of what we call Web 2.0.

A final consideration regarding the role of operators in the business of Web2.0 which both complain about the fact that providers of communications while others exploit these to their applications. Could begin to provide services of IASs and have added value.
honestly do not see them in the content business but if the infrastructure.
