Reactive microservices architecture is a new way of building scalable applications that are resilient, responsive, and elastic. It is based on the principles of the Reactive Manifesto, which promotes building systems that are responsive, resilient, elastic, and message-driven.
Reactive microservices architecture decouples services and components so that they can be independently scaled and deployed. This results in more flexibility and agility, and allows for more efficient use of resources.
Reactive microservices architecture is built on top of a reactive messaging system, which is responsible for routing messages between services. This makes it possible to add new services and components without affecting the existing system.

What is the difference between microservices and reactive microservices?
Reactive microservices are autonomous in nature and can only guarantee their own behaviour through API calls. Isolation of microservices allows them to operate independent of each other. Autonomous microservices have enough information to resolve conflicts and repair failures.
Reactive systems architecture is a computer systems paradigm that takes advantage of the responsiveness, flexibility and resiliency offered in reactive programming so that various components (eg, software applications, databases and servers) can continue to function and even thrive if one of the components is unavailable or struggling. This type of architecture can help to ensure that critical systems remain up and running, even in the face of challenging conditions.
What is the key characteristic of reactive microservices
Reactive microservices are those that are responsive, resilient, and elastic. They are designed to always be on and to quickly scale up and down as needed.
There are three main types of microservices architecture patterns: the API REST-based topology, the application REST-based topology, and the centralized messaging topology.
The API REST-based topology is the most common and popular type of microservices architecture pattern. In this type of topology, each microservice exposes a REST API that can be invoked by other microservices. This type of topology is easy to implement and is well suited for applications that need to communicate with each other over the network.
The application REST-based topology is similar to the API REST-based topology, but in this case, each microservice exposes a REST API that is used by applications to communicate with the microservice. This type of topology is well suited for applications that need to communicate with each other over the network and need to access the data stored in the microservices.
The centralized messaging topology is a type of microservices architecture pattern where all the communication between the microservices is handled by a central message broker. This type of topology is well suited for applications that need to communicate with each other over the network and need to access the data stored in the microservices.
What is difference between REST API and microservices?
Microservices are a great way to break up your application into smaller, more manageable pieces. They can perform different services and communicate with each other via REST APIs. This makes it easy to develop and deploy your application.
There are many popular Java frameworks for writing Microservices, including Spring Boot, Eclipse Vert.x, Oracle Helidon, and GoMirco. However, each of these frameworks has its own unique set of features and capabilities. In addition, there are many other Microservices frameworks written in other languages, including NodeJS (Molecular) and Golang (Quarkus).
What are the benefits of reactive microservices?
Reactive Microservices are a great way to offer isolation and autonomy at a level that traditional architectures cannot. Each Reactive Microservice has a single responsibility and publishes their capabilities through a protocol. This makes them message-driven and able to cooperate and collaborate without being tightly coupled.
Reactive systems are systems that responsive, resilient, and elastic.
Responsive: The system has to respond quickly to all users under all conditions.
Resilient: The system stays responsive in the face of failure.
Elastic: The system should provide responsiveness, despite increases (or decreases) in load.
What is reactive vs responsive web design
A responsive website is a website that automatically adjusts its layout to the screen size of the device it is being viewed on. This allows for a better user experience, as the website will be easy to read and navigate regardless of the device being used.
An adaptive website is a website that is specifically designed for a certain device type. This can often provide a better user experience than a responsive website, as the content and layout will be optimised for the specific device.
When you are ready to adopt a microservices architecture, you should keep the three C’s of microservices in mind: componentize, collaborate, and connect. Doing so will help you develop and deploy your services more effectively.
What are the 4 fundamental properties of microservices architecture?
Microservices architecture is an approach to designing a software system as a set of independently deployable services. This is in contrast to a monolithic architecture, where the entire system is built as a single unit.
There are six main characteristics of microservices architecture:
1. Multiple components: A microservices system is composed of multiple loosely coupled services. Each service is responsible for a specific task and can be deployed independently of the others.
2. Business approach: Microservices are designed around business capabilities, with each service being responsible for a specific business function.
3. Simple routing: Microservices use simple, direct routing. Each service has a unique URL and can be accessed directly by clients.
4. Decentralized: Microservices are decentralized, with each service having its own data store. There is no central point of control or data.
5. Failure resistant: Microservices are designed to be failure resistant. If one service fails, the others can continue to operate.
6. Evolutionary: Microservices are designed to be evolutionary, with new services being added over time to meet changing business needs.
1) Unit tests are the fastest and most lightweight tests. They exercise the functionality of a isolated component without depending on other services.
2) Service tests are heavier-weight than unit tests. They verify the functionality of a service by calling its API directly and typically mocking out any dependent services.
3) UI tests are the heaviest-weight and most brittle tests. They simulate a user interacting with the application through the UI.
Is microservices a 3 tier architecture
A microservice application is typically designed to have four tiers: platform, service, boundary, and client.
The platform tier provides the infrastructure and platform services that the application needs to run. This includes the operating system, runtime, middleware, and database.
The service tier contains the application’s business logic and exposes services that can be invoked by clients.
The boundary tier provides an interface between the service tier and the outside world. This can be exposed as an API or as a user interface.
The client tier contains the code that consumes the services exposed by the boundary tier.
Fine-grained SOA is the most common approach to microservices when just getting started. This pattern applies the same principles as service-oriented architecture but reduces the issues that would typically arise by breaking down the infrastructure into smaller, more granular pieces.
How do two microservices communicate with each other?
There are two common types of communication protocols used in microservices: synchronous and asynchronous.
Synchronous communication is typically used when invoking a regular Web API HTTP service. This type of communication uses a request/response model, where the client sends a request and then waits for a response from the server.
Asynchronous communication is typically used for communication between microservices. This type of communication uses a message passing model, where messages are sent between microservices without the need for a response. This allows for more flexibility and scalability, as each microservice can process messages at its own pace.
Microservices is more about architectural and design style, and you may be able to implement a Microservices without RESTful API. However, RESTful API makes it easy to build a loosely coupled Microservices. RESTful API was introduced prior to Microservices. It is one of the RPC protocols.
Conclusion
Reactive microservices architecture is an approach to designing and building microservices that emphasizes responsiveness, resiliency, and elasticity. This approach is based on the principles of the reactive manifesto, which advocate for building systems that are highly responsive, resilient, and elastic.
In conclusion, reactive microservices architecture is an architectural style that enables microservices to be chained together in an asynchronous and non-blocking manner. This results in a more responsive and resilient system that is better able to handle high levels of concurrent requests.
