Database as a Service (DBaaS) can help companies reduce costs and build scalable applications by streamlining the database management process. By using a DBaaS, development teams can focus on building real-time applications that scale while reducing the need for additional resources to manage databases. A good DBaaS can save time and money through efficient staffing, hardware efficiency, and built-in expertise in managing databases. Additionally, it can provide fast setup times and free trials for users with existing cloud credits. Overall, adopting a DBaaS can optimize database management, accelerate businesses' time to market, and ultimately reduce costs.
