This means developers do not need to take storage class into account when writing applications to interact with Cloud Storage data. The decision of which storage class to use in a given situation will ultimately depend on a number of factors, but most significantly: price, availability, and locality.
A good place to start is by estimating how often the data will be accessed. Specifically, consider short-term access frequency, as data can be migrated from Regional or Multi-Regional Storage to Nearline or Coldline Storage at any time. The impact of this is that ...
