A recent survey found that almost half of respondents still prefer to run databases inside a virtual machine — 30 percent said they would rather utilize a Database as a Service (DBaaS) offering. When conducting their own research, DBaaS provider Tesora found that the most important criteria for DBaaS — chosen by 47 percent of survey respondents — is the ability to integrate with existing production applications. For this reason, it is not surprising that end users are most likely to choose traditional databases “as a service” from major cloud providers AWS, Microsoft Azure and Google. Notably lacking in this chart are databases such as MongoDB and Redis offered as a service. In the future, we’d like to see research that included a broader range of DBaaS offerings.
