It depends on the cloud provider

4. What is the purpose of an API Gateway in a microservices ecosystem?

Load balancing

Authentication and authorization

Database management

Code deployment

5. Examine the role of an API Gateway in microservices and its impact on service communication.

It hinders communication between services

It centralizes service communication and provides additional features

It discourages service encapsulation

It avoids handling authentication and authorization

6. What is the purpose of API gateways in microservices architecture, and how do they facilitate communication?

API gateways hinder communication between microservices.

API gateways provide a single point of entry for client requests to microservices.

API gateways are only relevant in monolithic architectures.

API gateways focus on isolating microservices from each other.

7. What is the role of a polyglot microservices architecture, and how does it contribute to flexibility in technology choices?

It limits technology choices to a single language

It avoids using multiple programming languages

It encourages technology diversity for different services

It discourages third-party integrations

8. What is the primary goal of microservices architecture?

To create large, integrated codebases.

To break down applications into small, independent services.

To isolate services within monolithic architectures.

To complicate communication between services.

9. Which protocol is commonly used for communication between microservices?

SOAP

REST

GraphQL

UDP

10. How does containerization contribute to the deployment and scalability of microservices?

Containerization complicates deployment and reduces scalability.

Containerization is unrelated to microservices.

Containerization simplifies deployment and enhances scalability by packaging microservices into lightweight containers.

Containerization is exclusively used in monolithic architectures.
