Design Microservices Architecture with Patterns and Principles - WebSocket API Real-Time Two-Way Communications

The video tutorial explains the Websocket API, a technology enabling real-time, two-way communication between a browser and a server. It contrasts Websocket with HTTP, highlighting Websocket's bidirectional and stateful nature. The tutorial discusses Websocket's applications, such as chat and streaming dashboards, and its integration with backend and frontend systems. It emphasizes Websocket's ability to maintain persistent connections and facilitate efficient data transfer without complex polling mechanisms.

What is a key advantage of using Websocket over HTTP for client-server communication?

• Websocket supports real-time, two-way communication without polling.

• Websocket is more secure than HTTP.

• Websocket requires less bandwidth.

• Websocket is easier to implement.

How does Websocket maintain a connection between the client and server?

• By continuously sending keep-alive messages.

• By using a stateful protocol that keeps the connection open until terminated.

• By using a stateless protocol.

• By frequently refreshing the connection.

Which of the following is a characteristic of Websocket?

• It is a unidirectional protocol.

• It is a stateless protocol.

• It allows both client and server to send messages at any time.

• It starts with HTTP URLs.

What is the first step in establishing a Websocket connection?

• Performing a handshake to open the connection.

• Authenticating the client.

• Polling the server for a response.

• Sending a data packet.

Which application is NOT typically associated with Websocket?

• Email services

• Chat applications

• Streaming dashboards

• Real-time gaming
