The Big-Questions

 It is essential to consider various factors before starting any application development, including microservice-based applications. Here are some of the questions that need to be answered properly:

What are the business requirements for the application?

What is the expected user traffic and concurrency?

What are the non-functional requirements, such as performance, scalability, and security?

What are the technology stack and tools required for developing and deploying microservices?

What are the design principles and best practices for building microservices?

How to handle communication between microservices and ensure data consistency?

What are the deployment strategy and scaling mechanism for microservices?

How to handle errors and failures in microservices?

Answering these questions before starting any microservice-based application development is critical as it will help to ensure the success of the application.

IMHO the below questions also were answered properly before starting any microservice-based application development. What is your thought on this, comments will be highly appreciated:
