 If you are using server-side MVC frameworks like Ruby on Rails, Laravel or SailsJS, you are probably getting a hint here that the coming days are going to be a lot different with GraphQL. The `V` in MVC has already gone from the server-side in API only use cases. What's next? I can only speculate there will be rudimentary routing for our API servers, as we won't have a bunch of routes but a single endpoint. The schema will do a lot of validation for us, a lot of authentication & authorization will be on middleware layers, as they are now. The `resolve` function of the fields will probably take a lot of responsibility from controllers. The only least affected areas might be the models/ORM layer. Or maybe GraphQL will co-exists with REST and pre-dominant MVC style server-side architecture for a long time. I don't know. But I'm excited to embrace what's coming in the near future!

 One important difference between mutation and query operations is, if you post multiple mutations together, they are processed serially in order to ensure data integrity, whereas independent queries are processed concurrently by the GraphQL executor.
