Q

The multitenant architecture features shared system resources and what usage limitations?

A
  • All customers share the same computing power, custom-designed database, data storage, and core features.

Q

Multi-tenancy allows customers to receive regular upgrades throughout the year. What is unique about these updates?

A
  • Automatic, seamless upgrades are rolled out three times a year in Spring, Summer, and Winter.
  • All customers automatically get the same updates at the same time throughout the year.
  • Sandboxes are upgraded before production so that the changes can be previewed and tested

Q

Explain the Metadata-Driven Kernel?

A

Salesforce uses a runtime engine that materializes all application data from metadata, which is data about the data itself.

Architecture - There is a clear separation between the runtime database engine (kernel), tenant data, and metadata, which allows easy upgrades.

Deployment - Deployment of new or updated metadata components to production is strictly managed. Unit tests must cover no less than 75 percent of the application’s source code for deployment to production.

Q

How does the Lightning Component Framework handle performance?

A

The framework utilizes a stateful client (using JavaScript) and a stateless server (Apex). The client calls the server only when absolutely necessary, which results in fewer calls to the server and more responsive and efficient apps.

Q

In Salesforce, what is the different between a Client-Side Controller and a Server-Side Controller?

A

The JavaScript controller on the client side is used to perform client-side operations and also acts as the intermediary between the server and the UI.

The Apex controller on the server side is used to perform database operations. The JavaScript controller is used to call methods in the Apex controller.

Q

Does the Lightning Component Framework provide out of the box components?

A

The framework provides several out-of-the-box components which come with the Lightning Design System styling. These components can be found in the ‘lightning’ namespace and are available in two versions: Aura components and Lightning web components.
