Data Security in Cloud Computing

Businesses and governments are shifting more and more workloads to the cloud. But some organizations remain resistant to the cloud's considerable attractions due to lingering concerns about data security in cloud computing. While the concern is understandable, today's reality is that—when done right—data security in cloud computing can be as good or better than it is in traditional on-premise IT platforms.

Why Data Security in Cloud Computing Can Be as Good or Better than in Traditional IT

First it's worth asking, what does cloud mean? By the usual cloud computing definition, cloud providers make IT resources and applications available as a metered service that users can consume through the internet. Cloud services are typically classified into Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) such as raw computing power or cloud storage.

By its very nature, cloud computing involves some ceding of control from the customer to the service provider. But control and security are not identical. In fact, data security in cloud computing is potentially superior to security in the typical corporate data center due to the same forces that drive so much good through the marketplace as a whole: economies of scale and division of labor.

Because security costs are spread among a large number of customers in cloud data centers, cloud operators are able to apply far more resources to physical, technical, and operational security measures than can most corporations or government agencies. Many large providers also safeguard data security in cloud computing by operating multiple data centers with data replicated across facilities.

And unlike most corporations and public agencies, cloud providers' core business is operating and delivering IT services. Managed cloud providers thus bringing a level of experience and expertise to their data security operations that most organizations are hard-pressed to match.

But while security technologies and expertise in the cloud data center may surpass that in many corporate data centers, there remain valid concerns about security in what could be called the "fourth tier" of cloud architecture: the public internet, through which cloud services are delivered to end users. This is where Akamai can help.
