Public cloud’s uses are defined by reduced cost and scalability. Businesses searching for cost-effectiveness will be ultimately pulled towards public clouds; but they are by no means the most secure cloud storage service. Large companies are looking for more computing power to meet the demands of constant mobile connectivity. At the moment, the public cloud dominates the market in cloud computing.
A private cloud is a network created within a secured server system to provide secure cloud file sharing . Private clouds provide the same amount of access, storage and speed as a public cloud, but with added security and control. IBM’s Forward View explains, “This can often make private clouds more appropriate for specialized programs and systems unique to organizations with extremely sensitive data that must be protected.” For smaller businesses the added security developed behind a firewall allows expansion within the company and their vital information.
IBM suggests a mix of the two types of clouds, adding flexibility to any business. For confidential information, including advanced processing and customer data, use a protected private cloud for data security in the cloud. When dealing with simple applications, social media and product catalogs, for example, public clouds are appropriate. Combing private and public clouds in your organization’s IT portfolio maintains control over possible risks.
Nari Kannon from CIO.com makes a valuable argument, “It is common practice to procure high-bandwidth Internet connections for your data center from multiple vendors, precisely because you want to spread the risk of outages among many providers.” In short, using multiple clouds, public and private, spreads security risks and allows for more control when security problems do occur.
