Enterprises and governments are changing more workloads to the cloud computing technologies. But some organizations remain resistant to significant cloud attractions because of ongoing concerns about the data security in cloud computing. Despite the fact that the problem is clear, today’s reality is this: when secure data protection in cloud computing can be as good or better than traditional local IT platforms.
Why the data security in cloud computing can be as good or better than in traditional IT systems
First you need to ask, what does the cloud mean? According to the usual definitions of cloud computing, cloud providers provide IT resources and applications as a service that users can consume via the Internet. Cloud services are usually classified as Software as a Service (SaaS), Platform as Service (PaaS), and Infrastructure as Service (IaaS), such as computing power or cloud storage.

By its very nature, cloud computing involves some assignment of control from the customer to the service provider. But control and security are not identical. In fact, the security of data in cloud computing is potentially superior to security in a typical enterprise data center because of the same forces that produce equally good results in the overall market: economies of scale and division of labor.
Because security costs are distributed to a large number of clients in cloud data centers, cloud operators can use far more resources for physical, technical and operational security measures than most corporations or government agencies. Many large providers also provide data protection in cloud computing, managing multiple data centers with data replicated across all objects.
And, unlike most corporations and government agencies, the core business of cloud providers operates and provides IT services. Managed cloud providers, therefore, bring expertise and knowledge to their data security operations, which are difficult for most organizations to handle.
But while security technologies and expertise in the cloud data center can surpass this in many enterprise data centers, there are still concerns about security in what might be called the “fourth level” of cloud architecture: the public Internet, through which cloud services are provided to end users.
