Five Challenges in Private Cloud Networking

The basic goal of cloud networking is to provide users with connectivity even when applications and their components are hosted dynamically across a number of resource pools in dispersed private and public data centers. This will enable a Software as a Service (SaaS) model that makes applications appear to users exactly as they did when they lived on-premises.

Cloud Security Risk a Barrier?

Q
In the CompTIA 3rd annual Cloud Trends study (published in July 2012) 49% of IT executives were cloud-averse because of security. But now more executives including Richard Dorough, managing director of cybercrime incident and response for PricewaterhouseCoopers, believe data might actually be safer in the cloud. Is cloud security risk a barrier to cloud services adoption at your company?
Question from Michael Tidmarsh
A
For most organizations, I’d agree that data is probably safer in an established public cloud than in a local network. We ran annual surveys for a number of years and found that average security practices were pretty abysmal.

One likely extra risk is that a public cloud represents a larger target to attack. Though it might be more difficult to penetrate, it can also contain more items of value.
