What are some important things to consider when implementing a microservice architecture?

Microservices design considerations

• Single Responsibility Principal. A microservice should have single responsibility so that it will be easy to maintain and be reusable.
• Stateless.
• Programming frameworks.
• Data handling.
• Secrets Management.
• Dependency graph.
• Versioning.
• Containers.

How do you manage multiple Microservices?

Microservices and containers: 6 management tips for the long haul

1. Keep “KISS” top of mind.
2. Put your management plan into place – early.
3. Tap into an orchestration platform.
4. Develop a minimum set of operational capabilities.
5. Implement continuous integration and continuous delivery.

What type of testing is important in microservice architecture?

Integration Testing This critical part of microservice architecture testing relies on the proper functioning of inter-service communications. Service calls must be made with integration to external services, including error and success cases.

How would you communicate one Microservice to another Microservice?

There are two basic messaging patterns that microservices can use to communicate with other microservices.

1. Synchronous communication. In this pattern, a service calls an API that another service exposes, using a protocol such as HTTP or gRPC.
2. Asynchronous message passing.

How do you handle asynchronous calls in Microservices?

Microservices that communicate in an asynchronous manner can use a protocol such as AMQP to exchange messages via a message broker. The intended service receives the message in its own time. The sending service is not locked to the broker. It simply fires and forgets.

When should we use Microservices?

When to Use Microservices

1. When you want your monolithic application to accommodate scalability, agility, manageability and delivery speed.
2. When you have to rewrite legacy applications in today’s programming languages or tech stacks to keep up with modern-day business requirements and solutions.

What are the best practices to design microservices?( Multiple answers?

Best Practices for Designing a Microservices Architecture

• Create a Separate Data Store for Each Microservice.
• Keep Code at a Similar Level of Maturity.
• Do a Separate Build for Each Microservice.
• Deploy in Containers.
• Treat Servers as Stateless.
• Fast Delivery.
• Migrating to Microservices, Part 1.

What is microservices architecture testing?

Microservices Testing Approach Microservices strategy is an approach of developing an application by splitting it into smaller services, where each module runs in its own process and communicating with each other in a lightweight mechanism. These services are independently deployed and fully automated.
