What Microservice Architecture Really Means? : The Basics for Beginners

What is microservice architecture? In simple words

To make it very simple to understand, a microservices architecture is a method of developing software applications that divides an application into smaller, loosely linked services, each of which carries out a certain assigned task.

One benefit of this form of architecture is that it offers scalability, flexibility, and quicker development cycles, among other benefits. Additionally, it permits distinct teams to operate independently on various components, resulting in a quicker time to market for new features and services in accordance with business requirements.

Understanding the Architecture of Microservices in Detail

• Microservices architecture is a way of breaking down a large complex software application into smaller, independently deployable components or services.
• Each service is deployed independently and it runs in its own process boundary. Services communicates with each other through a well-defined API.
• Individual development teams can develop and deploy their services independently, which results in the faster development cycles and with that ,customers' changing needs may be accommodated more quickly.
• One interesting thing about microservices architecture is, services can be built using a language-agnostic approach, that means, it allows developers to develop the services as per the choice of their preferred language.
• Microservices are loosely coupled, which means each of the service can be independently maintained, enhanced and upgraded without affecting the other services.
• Microservices can be deployed on different on-premise servers or in the cloud, and also can scale independently, thus allowing for greater flexibility and scalability.

The 5 Characteristics Of Microservices

• Autonomy, ensures that each microservices can work independently of each other.

• Scalability, is about scaling up or down each microservices as required based on the performance needs 

• Modularity, helps to keep the code base of each microservices properly organized in a more meaningful and logical way

• Maintainability, is about each individual team can easily maintain, enhance or update the microservices

• Resilience, is about handling the failure scenarios and ability to quickly recover out of it is also one of the core characteristics of microservices.

Microservices Architecture in a nutshell

It is an architectural design approach and a method for developing software applications as a group of small, autonomous services that talk to one another through well defined APIs. Applications can be updated, enhanced and maintained more easily since each service can be deployed, scaled, and managed independently.
