Polyglot Persistence

Abstract

So far, we have seen that no single database, be it Sql or No-Sql, has been able to satisfy all the business needs. Prior to mass flooding of the world with mobile devices (cell phones and tablets) and even IoT devices, it might have been fine to use a relational database for most applications. However, the advent in social media and the ever-increasing number of users have led to polyglot persistence being the panacea for scalability. In Figure 3-10, we had arrived at an architecture that could scale most of the business applications. We had created a scalable set, and we displayed two sets that were being fed traffic by a system-level redirector.
