It is a software development methodology where a product is composed of various independent services, each managing its own specific functionality.</p> <p><a href="https://media.dev.to/cdn-cgi/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fhhmwus4cigti5uedkaih.jpeg" class="article-body-image-wrapper"><img src="https://media.dev.to/cdn-cgi/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fhhmwus4cigti5uedkaih.jpeg" alt="Image description" width="800" height="449"></a><br> It differs from the traditional monolithic architecture. In a MA, all business functionalities are written within a single codebase. On the other hand, microservices break down a product into various independent services, where each component handles its specific functionalities</p> <p>Now we will cover the main concepts behind microservices. </p> <p><a href="https://media.dev.to/cdn-cgi/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fg7nva74ed4r3wf9hojv0.jpeg" class="article-body-image-wrapper"><img src="https://media.dev.to/cdn-cgi/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2Fg7nva74ed4r3wf9hojv0.jpeg" alt="Image description" width="800" height="449"></a></p> <ul> <li><p>Firstly, it has individual components which operate independently. They can be developed and deployed individually </p></li> <li><p>Secondly these services are robust and handle failure very well. If one service fails, it can temporarily interrupt requests to that service without bringing down the entire system.</p></li> <li><p>Thirdly, with a simple routing process, it ensures seamless communication and interaction between individual components</p></li> <li><p>Also, it has decentralized operations, where each services functions independently</p></li> <li><p>Lastly, due to its valuable features this type of architecture is widely adopted in modern businesses</p></li> </ul> <p>*<em>Finally, we will go through pros and cons of microservices<br> *</em></p> <p><a href="https://media.dev.to/cdn-cgi/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F2q77m4nojke2rphj55p1.jpeg" class="article-body-image-wrapper"><img src="https://media.dev.to/cdn-cgi/image/width=800%2Cheight=%2Cfit=scale-down%2Cgravity=auto%2Cformat=auto/https%3A%2F%2Fdev-to-uploads.s3.amazonaws.com%2Fuploads%2Farticles%2F2q77m4nojke2rphj55p1.jpeg" alt="Image description" width="800" height="449"></a><br> *<em>Pros: *</em></p> <ul> <li>Scalability: Microservices allow each service to be scaled independently based on demand. Using this we can optimize resource usage and improve overall system scalability.</li> <li>Flexibility in Technology: Different services within a microservices architecture can use different technologies, and frameworks. This allows teams to choose the best tools for each specific service.</li> <li>Maintainability: With individual services codebases are easier to understand, develop, and maintain.</li> <li>Organizational Alignment: Moreover, this aligns well with agile and DevOps practices. It fosters autonomy and rapid iteration.</li> </ul> <p>*<em>Cons:<br> *</em></p> <ul> <li>Complexity: With increasing number of services it introduces operational complexity.</li> <li>Testing Complexity: Each service in this model requires thorough testing individually and integration testing across services.</li> <li>Costs: Finally, this architecture leads to an increased infrastructure and operational costs.</li> </ul>
