The Challenge – Stopping The Nosy Neighbor
By sharing application, compute and network resources in a virtual or cloud environment, business unit’s and cloud service providers (CSP) can boost IT speed and efficiency, business agility, resource utilization, and profitability. That’s a given. But to achieve these benefits without taking on unmitigated risks, cloud tenants’ critical applications and confidential data must be as secure and compliant as they have been in the traditional data center. In particular, every tenant’s workload must be completely isolated from every other tenant’s workloads and administrators.
Putting air gaps between servers and network segments was once an effective way of isolating critical applications but today “air gapping’ just doesn’t make sense. The poor resource utilization rate would be enough to take a huge bite out of a private cloud ROI. The economics of cloud require highly efficient logical segmentation and isolation of tenant workloads.
For organizations to effectively isolate their workloads they need to:
