Amazon RDS will be used to host our production DB. It is Amazon's offering for hosting mySQL databases. It is simple to connect it to EC2 or Lightsail instances. It is advantageous for us to use because it offers 20GB of free storage which will be enough for our machine learning model data. There are many alternative options to the RDS, but this is the only that keeps all our infrastructure in the same place and the simplest to set up given the rest of our tech stack.
