Cloud computing is has become a popular trend in recent years. However, as popular as it is there is still much confusion as to how cloud services work to the average user. Aside from thinking of a way to access data using the Internet, many businesses are unclear of the types of cloud services available and what is the best option for them. In addition, there are still a handful of companies that choose not to move to the cloud due to security concerns. This post is to help clarify some common misconceptions and provide clarity on strong ways to utilize cloud technology for your business.
The chart above summarizes the major difference between the two cloud options available to companies. Public cloud platforms such as Amazon Web Services and Google are shared network infrastructures that are (usually) found at a lower cost and quicker implementation. However, there are security concerns that should not be overlooked. Because public clouds host data for many organizations, they are known to be a larger target to hackers (although they also generally hire some of the best security people for that reason as well). In addition, organizations lose control of their data as it is migrated to a public cloud. Lastly, there is a higher likelihood of cross-tenant data leakage due to vulnerabilities of a shared network infrastructure. This isn’t to say public cloud solutions shouldn’t be considered. if the data you are looking to host isn’t business sensitive or mission critical and are just looking for a simple solution, such as a backup service, public cloud services could be a great option for you.
On the other hand, private clouds are known to offer greater peace of mind when it comes to security. Because they operate on a private network as compared to a shared space with other organizations, it reduces the likelihood of similar security issues and organizations also get to maintain a greater sense of control over their data. However, in a private cloud environment, it’s important to ensure that the provider has the proper certifications for their data center such as SSAE16. Now, the biggest reason more organizations don’t utilize private cloud services is due to the high investment necessary when factoring in the cost of data centers and technologists to build out a private infrastructure.
One analogy comparing public and private clouds would be to ask whether you’d prefer to store your company’s data in a shared college dormitory or your personal home.
