multi-tenant cloud

Contributor(s): Sarah Wilson
This definition is part of our Essential Guide: Private cloud implementation guide

A multi-tenant cloud is a cloud computing architecture that allows customers to share computing resources in a public or private cloud. Each tenant's data is isolated and remains invisible to other tenants.

In a private cloud, the customers, who are also called tenants, can be different business divisions inside the same company. In a public cloud, the customers are often entirely different organizations. Most public cloud providers use the multi-tenancy model. It allows them to run one server instance, which is less expensive and makes it easier to deploy updates to a large number of customers.

Most Cloud Providers do a good job of hiding the data another tenant might have stored on a cloud system that you aren't using.  This is by design.  However, the fact that this happens on shared multi-tenant clouds should not be construed as a guarantee of security.

I would review the security profile of any multi-tenant cloud I planned to use, before putting my companies data, potentially at risk for a higher level 'cloud' breach.
Veretax! Thank you for your comment.
I'm trying to learn more about the subject.
We've seen some breaches recently such as the Equifax case...but there is always a risk correct?
I mean, AWS, Amazon's largest revenue portion comes from their infrastructure services. Their are selling multitenant cloud and yet, we could argue it is somewhat secure to have data stored there?
I'd love to understand why not leave your data with Amazon or Microsoft Azure?
