What is the “tri-nature of everything” theory in the context of system design?

Every system consists of three main components: a dependency, a purpose, and an exposure layer.
Every system consists of three main components: a dependency, a database, and a user interface.
Every system consists of three main components: a server, a client, and a database.
Every system consists of three main components: a front-end, a back-end, and a middleware.

How does the speaker suggest building microservices for a course registration system?

Each microservice should share its resources and a coordination service can be used to manage resource allocation.
Each microservice should own its resources and a coordination service can be used to manage resource allocation.
Each microservice should share its resources and an orchestration service can be used to coordinate between different microservices.
Each microservice should own its resources and an orchestration service can be used to coordinate between different microservices.

How does the speaker illustrate the concept of the “tri-nature of everything” theory using a simple API?

With a database as the dependency, a service for business logic as the purpose, and a UI component as the exposure layer.
With a storage broker as the dependency, a database as the purpose, and a UI component as the exposure layer.
With a storage broker as the dependency, a service for business logic as the purpose, and a UI component as the exposure layer.
With a storage broker as the dependency, a service for business logic as the purpose, and a database as the exposure layer.

What is the role of a storage broker in the system design described by the speaker?

It is used for different storage engines and a concrete implementation is chosen based on the service required.
It is used for different databases and a concrete implementation is chosen based on the service required.
It is used for different UI components and a concrete implementation is chosen based on the service required.
It is used for different services and a concrete implementation is chosen based on the service required.

How does the speaker describe the importance of validation at different levels of the system?

How does the speaker apply the principles of microservices to larger enterprise systems, using Microsoft as an example?

He explains how different teams within Microsoft can be seen as different databases, each with their own dependencies, purposes, and exposure layers.
He explains how different teams within Microsoft can be seen as different microservices, each with their own dependencies, purposes, and exposure layers.
He explains how different teams within Microsoft can be seen as different UI components, each with their own dependencies, purposes, and exposure layers.
He explains how different teams within Microsoft can be seen as different storage brokers, each with their own dependencies, purposes, and exposure layers.

How does this schooling system follow the principles discussed by the speaker?

It follows the "tri-nature of everything" theory but not the concept of microservices.
It follows the concept of microservices but not the "tri-nature of everything" theory.
It does not follow either the "tri-nature of everything" theory or the concept of microservices.
It follows the "tri-nature of everything" theory and the concept of microservices.
