Master Microservices with Spring Boot and Spring Cloud - What is a Web Service?

The video tutorial explains the concept of web services, starting with a basic definition and exploring whether all web applications qualify as web services. It uses a todo application as an example to highlight the challenges of application integration and the limitations of HTML for machine-to-machine communication. The tutorial introduces the W3C definition of web services, emphasizing the need for interoperability, application-to-application interaction, and network communication. It concludes by summarizing the key features that define a web service.

What is a key difference between a web application and a web service?

• Web services are designed for human interaction.

• Web applications are designed for machine-to-machine interaction.

• Web applications are not necessarily web services.

• Web services cannot be delivered over the internet.

Why can't the current to-do application be used as a web service?

• It delivers HTML output, which is not suitable for application-to-application interaction.

• It lacks a login feature.

• It is not accessible over the internet.

• It is built using Java and Spring MVC.

What is a limitation of using a jar file for sharing business logic?

• It involves local communication, not over a network.

• It requires no additional dependencies.

• It is suitable for application-to-application interaction.

• It automatically updates with new business logic changes.

According to the W3C, what is a web service designed to support?

• Human-to-machine interaction over a network.

• Interoperable machine-to-machine interaction over a network.

• Local communication within a single system.

• HTML-based data rendering.

What is a requirement for an application to be considered a web service?

• It must be built using Java.

• It should allow communication over a network.

• It should be installed locally.

• It must deliver HTML output.

What does 'interoperable' mean in the context of web services?

• Only applications built with the same technology can interact.

• Applications must be on the same network.

• Applications of different technologies can interact.

• Applications must use the same database.

What is a key feature of a web service that differentiates it from a local application?

• It allows communication over a network.

• It requires no dependencies.

• It is designed for human interaction.

• It is built using HTML.
