When it comes to databases and AWS VPC, best practice is to place your database in private subnet. By definition, private subnet in AWS is not reachable from the Internet because no Internet gateway is attached to private subnet. This is the way you protect your data. This kind of configuration is good for security but bad for data management.

There are two basic ways to acees it.

1. Access postgres RDS from bastion host. There are following requirements for this.

function FetchPokemon({pokemonName}) {
  const pokemon = cache[pokemonName]
  if (!pokemon) {
    const promise = fetchPokemon(pokemonName).then(
