The private cloud for more security

Outsource its data and therefore its heritage remains a difficult decision for most business leaders. Technically and legally many questions are still complex and vague answers. However, a reflection on the infrastructure component offers Cloud allows to move towards more reassuring solutions for businesses.

Companies that intend to optimize their IT resources are reluctant to take the step of outsourcing their technical infrastructure and SI. The issues raised within the safety levels : guarantee security and access to their data, physical location of servers eg. Many analysts table on the Private Cloud solution.

But what the private cloud ? The commonly accepted definition is the result of dedicated infrastructure for a client. Companies with a private cloud would have access to the infrastructure to the creation and destruction of virtual machines and storage resources.

These offers private cloud respond well to the application of traceability, because it is the company itself created its virtual machines, in a well identified datacenter. They can also address the issue of security, provided that the networks are well segmented and isolated.

However, it is interesting to return to the definition of cloud computing : remote access to computing resources on demand. Dedicating an infrastructure company goes somewhat against this concept, and does not provide the benefits of investment : costs of computing resources are fully supported by the company, whatever its use. Regarding the power consumption, it can not be adjusted if the system of private cloud pemet off unused servers. In practice, few companies are encouraged to extinguish, because current offerings take little account of the power consumption.

The commonly accepted definition of private cloud is a virtualization infrastructure dedicated ; but it does not have the benefits of cloud computing …

Can we reconcile the imperatives of security companies with the benefits of cloud ?
We believe that this is possible with a shared infrastructure, but whose networks are private. In this model, companies have access to a private network virtual machines on a shared platform. The network is an essential basis for safety. It allows you to define which users have access to what resources. It also limits and plot areas where data. If the zones are not routed on the Internet, is a key element of security.

From the moment we define the « private cloud » is the cloud on a private network ; not a cloud « dedicated », then companies can reap the benefits of cloud : consumption of virtual machines on demand, billing according to consumption. The host will share resources between several companies, and will optimize the energy consumption of these machines to reduce costs. This solution seems more virtuous and more economically efficient.

The definition of private cloud seems therefore to be reviewed. Rather than dedicated infrastructure for business, it is rather a shared infrastructure on a private network that allows for the benefits of cloud computing. Remains to find the right hosting network solutions to ensure customers that their resources are well protected.
