Chapter 5. A Reference Architecture for Developers

“Everything deep is also simple and can be reproduced simply as long as its reference to the whole truth is maintained. But what matters is not what is witty but what is true.”

— Albert Schweitzer

Resource tier

The most bottom of the tiers is the resource tier it includes the back-end which can support the services that will be the data or processing needed for creating a rich user experience.
