**Overview**
Microservice is an architecture that bracks an application into smaller, independent services that run unique processes and make applications easier to scale and faster to develop, enabling innovation and accelerating time-to-market for new features. Each service is designed for a set of capabilities and focuses on solving a specific problem. If developers contribute more code to a service over time and the service becomes complex, it can be divided into smaller services, which can
be referred to as microservices:

**What exactly are microservices?**
Microservice, or microservice architecture, is an approach to structuring applications. Microservices are software architectures where the functionality of an application is broken into smaller independent deployable services. Each services focuses only on a single functionality of the application and are isolated from the other, making them independent. These services can be developed, deployed, and scaled independently, which can lead to increases in agility and make an application easier to menten and avoid complex orchestration between them.

**How does microservice work?**
In a microservice architecture, an application is divided into services. Each service runs a different, unique process. And it is usually managed on a database. A service can handle user information, authentication, log-in data, and other tasks.
What is microservice architecture used for?
Microservices are used to seed up application development and to maintain service independently on an application. Microservices typically communicate through APIs or Web services and can be implemented using various programming languages and technologies. This approach is often contracted with monolithic architectur
Within a microservice architecture, each one is a single service built to accomplish features and handle discrete tasks. microservices communicate with other services, through simple interface to solve business problems.

**Monolithic vs. Microservice**
With a monolithic architecture, all processes are run as a single service. This also means that if one service or application spikes in demand, the entire architecture will be scaled. Adding or improving a monolithic becomes more complex as the code base grows. This complexity limits experimentation and makes it more difficult to implement new ideas.
With microservice architecture, all processes of the application run independently, which makes it easier to implement new ideas into the application. These services communicate via a well-defined interface using lightweight APIs. Services are built for business capabilities, and each service performs a single function. Each service 
can be updated, deployed and scaled to meet demand specific function of an application.

**Benefits of microservice architecture:**
There are several advantages to microservices that support application development. Here are a few advantages of microservice architecture:

- **Freedom of Technology:**
Microservice architecture provides the teams to have the freedom choosing the right technologies and tools to solve their specific problems. As a consequence, teams building microservice allow the team to choose the best tool for each services.

- **Easy Development:**
Microservice architecture enables continuous delivery and continues integration, making it more easy to implement new ideas and roll back if something don't work, And it make it easy to update code, and accelerate time-to-market for new features.

- **Media Content:**
Using microservice architecture, video and images can be stored in a scalable object storage system and served directly to the web.

- **Data pricing:**
A microservice platfrom can extend cloud support for existing modular data processing services.

- It can be developed using different programming languages and tools.

- It helps in managing development time.

Summary
An application can be broken down into smaller, independent services with distinct functions through the use of microservice architecture, 
which speeds up development and by cutting down on the time it takes to launch new features. Every service is tailored to a certain set 
of skills and aims to address a certain issue.
