Dapps offer the same data storage and computations that can be performed using web services with centralized databases. Here I compare performance metrics and the cost of services between the two. Specifically I compare write speed, write costs, data storage costs, and sync speed. I use Amazon web services (AWS) as the benchmark for efficient web services and BerkleyDB for a database that is accessible to anyone today. I use Ethereum since it is the most popular dapp platform.
