2) SOAP
3) SMTP
4) SSH

Final answer:

The most suitable option for implementing communication between microservices in an Azure Kubernetes Service cluster is RESTful APIs. RESTful APIs allow for stateless communication between systems over HTTP, providing a standardized way for microservices to interact with each other by defining endpoints and HTTP methods. SOAP, SMTP, and SSH are not the most suitable options for microservice communication.

Step-by-step explanation:

The most suitable option for implementing communication between microservices in an Azure Kubernetes Service cluster is RESTful APIs. RESTful APIs, or Representational State Transfer, are a set of architectural principles that allow for stateless communication between systems over HTTP. They provide a standardized way for microservices to interact with each other by defining a set of endpoints and HTTP methods.

SOAP, SMTP, and SSH are not the most suitable options for implementing communication between microservices. SOAP is a protocol that uses XML to structure messages, which can be more complex and heavy-weight compared to RESTful APIs. SMTP, or Simple Mail Transfer Protocol, is commonly used for sending emails and not for microservice communication. SSH, or Secure Shell, is a network protocol for secure communication and is typically used for remote administration and file transfer.

For example, if you have a microservice that provides customer data and another microservice that needs to retrieve customer data, you can define a RESTful API endpoint in the customer microservice to handle the HTTP GET request for retrieving customer data. The requesting microservice can then make an HTTP GET request to the customer microservice's endpoint to fetch the required data.
