The cloud begins to be a constant in the messages of technological companies. There are more and more solutions for companies to jump into the cloud. Delimited to private, public or hybrid cloud, choosing where each data should go can be a complicated but key task for the success of the project.
In this marabunta of options cloud we wanted to put our grain of sand to help choose the one that best suits each type of company, usual doubts among customers. It is not the same to face a project of a micropyme that to do it for a great corporation. Although the two can be just as important, the requirements and necessary clouds can be very different.
So, what are each cloud used for? Where can we implement the solutions of each company?
The solutions framed within the private cloud are intended for exclusive use by the company. Hence, generally associated with this cloud is information about the company that can be used internally (private internal cloud) or by providers (external private cloud). But in either case, ownership of the cloud belongs to the enterprise.
The private cloud requires large security measures of both the data and the platform on which they are stored. In addition, you need to have a very high availability and access service so that the company or third parties can manage the information at all times.
All the security and availability advantages of a private cloud solution are reported in the price. Both investment and maintenance costs are often higher than other clouds.
For what type of companies: by the conception of the private cloud, this model of cloud is designed for any company. However, this formula will fit much better in a large corporation, with more budgets to invest, than in an SME where there are many more limitations. Thus, the large account will use much more this cloud than the small and medium.
Unlike the private cloud, in the public option the service belongs to a third provider and not to the company. However, this does not mean that it is public to anyone but simply the power over its use not only resides in the company itself but also the supplier of the cloud service.
Generally, the public cloud usually has a multi-use infrastructure, that is, that can be used by different users or companies for free or paid. In addition to this difference in costs, the flexibility of contracts is usually much broader.
However, the public cloud is not perfect either. Since the cloud has less costs and belongs to another company, the availability, security and transparency of the platform will depend on the company owner. Parameters on which you can not have so much control.
For what type of companies: the formula of the public cloud is very focused on small companies since the saving of costs is vital for them. Of course, it can be useful for large people who want to host less important data.
Hybrid models are a hodgepodge of the previous two types. This cloud combines private and public solutions to create a heterogeneous environment. So depending on the architecture and the data that you want to save, you can use one or the other.
The advantages of using the hybrid cloud are derived from the above: a reduction of costs if you combine more economical and private public solutions with higher prices. To this is added the flexibility provided by this mixture.
But there are also risks. Being in two clouds, it is easy in the long term to integrate more sensitive data in the public cloud and on the contrary. Especially if we are facing large corporations where sensitive information for many hands. In addition, this type of infrastructure is much more complex and problematic because they must combine much more technology.
For what type of companies: as we say for large companies can become a problem rather than a solution. However, in the case of small companies it can be a good way to protect the most valuable data while saving costs with the combination of a public cloud.
