Introduction to Laravel as Microservice

As you must know, or as implied by the microservices definition, a microservice is a collection of freely deployable services. It is an approach to building application software as a collection of independently deployable, compact, modular services. Herein, each service executes a different operation and interacts with one another via a simple, well-defined interface.

In light of that, you must ponder how we can implement microservices in Laravel. How does Laravel architecture work on microservices? Well, here’s how PHP Laravel microservices work!

Laravel Microservices Architecture

Before beginning with Laravel architecture on Microservices, let’s talk about Laravel first. Laravel is one of the foremost widely used frameworks for developing custom applications. Laravel gives its developers the proper tools to create anything from websites to web applications. All in all, it is quicker to deploy, easier to maintain, and more reliable.

If we speak in numbers, Laravel boasts over 56,000 developers worldwide. It is the highest-starred PHP framework on GitHub and is brimming with powerful features.

Microservice Architecture with Laravel

In contrast to the monolithic architectural style, which is used when an app is constructed as a single structure, microservices is a method to develop a single program as a suite of separate sections, services connected by APIs. It allows the creation of several microservices that can be controlled by various teams and coded in various programming languages.

Microservices here, a type of software architecture, unifies massive Laravel applications in a modular way depending on Small Building Blocks that concentrate on a specific duty and activity. Blocks interact with one another via a set of language-independent/language-agnostic APIs.

Dew Computing is a notion that correlates to Laravel architecture styles by using a microservices architecture to calculate the potential of numerous little dews (denotes the functional components of microservices).

The 3 prime reasons that modern enterprises need microservice architecture are:
● To defend against a failure of traffic or performance surge.
● To scale graciously
● To reduce the number of individuals engaging in each codebase.

Advantages of Laravel Microservices

The microservice design has several advantages. Generally, microservice in Laravel is narrowly targeted, allowing them to be lighter and function considerably faster.

Moreover, it only involves microservices API calls. Different languages may be used for certain services. Notification services, for example, might be written in NodeJs. Therefore,it’s not mandatory to use either Laravel or Lumen.

According to usage, every service can be scaled. In summary, it might work well for huge applications. Besides this, some of the advantages of Laravel Microservices are:

Advantages of Laravel Microservices

One-on-One Deployment

It is simpler to deploy. There is less danger of system crash when something goes wrong since microservices can be implemented on distinct virtual machines, physical machines, or Docker containers. This is because services are fully independent.

Resilient Module Boundaries

Microservices strengthen modular architecture, which is essential for bigger teams.

The Simplicity of Upgrading & Maintenance

Microservices can easily be upgraded and maintained autonomously because they are built on separation.

Diversity in Technology

Microservices can be combined by developers using a variety of development frameworks, coding languages, and data-storage systems.

Versatile Across All Coding Languages

Developers can create Microservices in whatever programming language they are comfortable with. Consequently, they can subsequently offer APIs per the REST or RPC protocols.

When Should You Opt to Go For Laravel Microservices?

Generally, you should use Laravel microservices when your application,

  • Is being built from the ground up.
  • Is a monolithic program.
  • Is rebuilding (or refactoring) a legacy
  • Introducing new features to an app that already exists.
  • Has a challenge is scaling.
  • Has low productivity.
  • Becomes challenging to maintain.

In any of these situations, Laravel microservices framework can be implemented. However, it is frequently employed in order to convert monolithic old applications into a microservices architecture.

In essence, there are 4 basic causes for it:

  • Organizational and project scaling challenges emerge because the application grows too large for developers to comprehend.
  • The application is divided into various components, each of which has its own separate update and release cycle.
  • It is necessary to dynamically scale some system components up and down without affecting other components.
  • Different system components have unique industry or technical requirements that compel developers to adopt a programming language or framework other than the team’s standard programming language.

Best practices and challenges while using Laravel with Microservices

Laravel With Microservices Best Practices

With business owners’ increasing preference for microservices architecture, Laravel’s microservices architecture is a viable choice. It helps boost the overall efficiency and efficacy of your business application. However, certain best practices can be leveraged to bring out the true potential of your business application via Laravel Microservices.

Independent Microservices

Microservices are introduced to uphold service independence, with each microservice defining specific functions and contributing to overall efficiency. Here are key strategies to ensure this independence:

  • Minimal Dependencies: Reduce dependencies between microservices to maintain their autonomy.
  • Clear Communication: Establish well-defined APIs like RESTful or messaging protocols for seamless inter-microservice communication.
  • Data Isolation: Implement separate databases for each microservice to prevent data coupling and ensure data integrity.
  • Autonomy Promotion: Encourage autonomy within microservices to enable rapid development and deployment cycles.
  • Containerization: Leverage containerization tools like Docker to encapsulate microservices and their dependencies.
  • Orchestration: Using orchestration tools like Kubernetes to manage and scale microservices independently ensures efficient resource utilization.

By implementing these strategies, organizations can effectively harness the benefits of microservices architecture while maintaining service independence and scalability.

Utilizing The API Gateways

Utilizing API gateways means setting up a main access point for all your microservices. This hub manages user authentication, access permissions, and usage limits, making interactions safer and more controlled. It also directs requests to the right microservices and handles technical tasks like logging and monitoring. This simplifies the development of microservices by dealing with common issues in one place. Additionally, an API gateway allows seamless updates and changes to microservices without disrupting client applications.

Implementing The Service Discovery

The mechanisms, such as Consul, function as a centralized entry point for all microservices, streamlining authentication, authorization, rate limiting, simplifying client interactions, and enhancing security scalability. To achieve this, ensure that each microservice registers itself with the chosen service registry upon initialization, making its location and availability known. Utilize the service registry to locate required services, as microservices need to communicate with each other. Activate health checks within the service registry to ensure that only healthy microservices are discovered and utilized. Consider leveraging features of Laravel API Gateway or explore specialized API gateway solutions like Kong and Apigee.

Using Asynchronous Communication

Use the Laravel queue system or messaging platforms like RabbitMQ or Kafka for asynchronous communication between microservices. This enhances performance and facilitates efficient management of background tasks. You can decouple services by leveraging asynchronous events or messages, enabling each microservice to function independently and asynchronously. This promotes an event-driven architecture, facilitating communication between microservices through events and promoting loose coupling and scalability. Developing an error-handling mechanism to manage failures and ensure reliable message delivery in asynchronous communication is essential.

Challenges While Using Laravel Microservices

Laravel is a great choice for building web applications thanks to its extensive features and functionalities. However, incorporating microservices with the Laravel framework presents certain challenges. Let’s take a glimpse of those challenges.

Deployment Complexity

To address these challenges effectively, start with the following best practices:

  • Implement Automated Deployment Process: Implement an automated deployment process to ensure consistency and reduce manual errors.
  • Utilize Containerization Technologies: Use containerization technologies like Docker to package each microservice and its dependencies. This streamlines deployment across different environments.
  • Leverage IaC Tools: Infrastructure-as-Code (IaC) tools such as Terraform or AWS CloudFormation define and manage infrastructure consistently and in a repeatable manner.
  • Employ CI/CD Pipelines: Use continuous integration and continuous deployment (CI/CD) pipelines to automate microservices’ building, testing, and deployment. This ensures fast and reliable deployment.
  • Thoroughly Document Processes: Document the deployment process thoroughly to ensure clarity and consistency.
  • Provide Training: Train the development team on the deployment process and tools used.
  • Seek Expert Advice: For valuable insights and best practices, seek advice from microservices architectures and deployment experts like Bacancy.

Increased Overhead

Addressing the demands of microservices involves overcoming a frequent hurdle: accommodating the necessary resources and processing power due to the dispersed design of microservices architecture. As the number of microservices grows, the complexity of managing and coordinating them increases, leading to greater overhead. Development teams can optimize code, utilize efficient communication protocols, and adopt load-balancing techniques to tackle this challenge. Employing automation tools for deployment and monitoring can streamline operations and minimize unnecessary overhead.

Difficulty Debugging

Debugging issues across microservices is challenging due to their distributed nature, lack of centralized logging, and increased complexity. However, you can overcome this challenge by implementing comprehensive logging to monitor data flow and errors within each microservice. This makes debugging easier. Integrate tools like Sentry or New Relic for error monitoring and reporting across your microservices architecture, aiding in issue identification and resolution. Additionally, utilize distributed tracing tools such as Zipkin or Jaeger to track requests as they move through different microservices, aiding debugging complexities. Establishing a centralized system for handling exceptions ensures uniform error handling across microservices, streamlining the debugging process.

Data Inconsistencies

Data inconsistencies often arise within microservices due to their distributed nature. Factors like network latency and concurrent updates contribute to these inconsistencies across microservices, impacting system reliability and data integrity. However, you can tackle this by adopting strong data consistency strategies like event sourcing or distributed transactions, employing compensating transactions and idempotent operations, implementing event consistency when immediate consistency isn’t necessary, leveraging event-driven architecture and message queues for orderly event processing, and regularly monitoring and reconciling data across microservices can help identify and resolve inconsistencies, ensuring effective management of potential data inconsistencies.

How to Build Microservices with Laravel Lumen (Tutorial)

In this Laravel Microservices example tutorial, we will learn how to create microservices in Laravel (Lumen); following this step-by-step tutorial, you can create your APIs for your application.

Build Microservices with Laravel Lumen

About Laravel-Lumen

Like Laravel, Lumen has also been created by Taylor Otwell, And it has been designed keeping in mind the microframework architecture. There are more frameworks (Slim, Silex) like Lumen that you can use for microservices.

Initial Set-Up

To install Lumen, you must first install composer. You can download the latest version of Composer by visiting the getcomposer.org

Install Lumen

Install Lumen via Composer:

Copy Text
composer global require "laravel/lumen-installer"

The below command will create a new Lumen project with all required dependencies.

Copy Text
lumen new demo

Serve your application with the below command.

Copy Text
php -S localhost:8000 -t public

Configure Your Application

Step 1: Configuration

In the .env file, replace the value with the following values and also fill in the details of the database.

Copy Text

Database and Migrations

We will create a migration file. This file automatically creates the table in the connected database by running migrate command. A migration file will be created inside the database/migrationsdirectory.

Copy Text
php artisan make:migration create_products_table

Add this below code to the created CreateProductsTable migration file.

Copy Text
use Illuminate\Database\Migrations\Migration;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Support\Facades\Schema;

class CreateProductsTable extends Migration
    * Run the migrations.
    * @return void
   public function up()
       Schema::create('products', function (Blueprint $table) {

    * Reverse the migrations.
    * @return void
   public function down()

Run this command.

Copy Text
php artisan migrate

Create a Model File

Lumen doesn’t support the below-given make: command

Copy Text
php artisan make:model Product

Go to the app directory, create a new model called Product.php and paste the following code.


Copy Text
namespace App;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
   protected $table = 'products';
    * The attributes that are mass assignable.
    * @var array
   protected $fillable = [
       'name', 'price', 'description'


Now load Eloquent and Facades by uncommenting the following code located in the bootstrap/app.php Directory.

Copy Text


Setup Controller Files

Go to the app\Http\Controller and create a new file ProductController.php and paste the below-mentioned code.

// app/http/controllers/ProductController.php

Copy Text
namespace App\Http\Controllers;
use App\Product;
use Illuminate\Http\Request;

class ProductController extends Controller
    * Create a new controller instance.
    * @return void
   public function __construct()
    public function index()
      $products = Product::all();
      return response()->json($products);

    public function create(Request $request)
      $product = new Product;
      $product->name= $request->name;
      $product->price = $request->price;
      $product->description= $request->description;
      return response()->json($product);

    public function show($id)
       $product = Product::find($id);
       return response()->json($product);

    public function update(Request $request, $id)
       $product= Product::find($id);
       $product->name = $request->input('name');
       $product->price = $request->input('price');
       $product->description = $request->input('description');
       return response()->json($product);

    public function destroy($id)
       $product = Product::find($id);
       return response()->json('product removed successfully');

Setup Routes Files

Now add this code to routes/web.php. Create Group routes function to our routes and add the prefix to them.

Copy Text
$router->group(['prefix'=>'api/v1'], function() use($router){

   $router->get('/items', 'ProductController@index');
   $router->post('/items', 'ProductController@create');
   $router->get('/items/{id}', 'ProductController@show');
   $router->put('/items/{id}', 'ProductController@update');
   $router->delete('/items/{id}', 'ProductController@destroy');


Testing APIs

We can use postman to test APIs; if you use VScode, you can also test APIs with the thunder client. In this tutorial, we will use postman.

Method – GET– Request with all items preview:

URL – http://localhost:8000/api/v1/items

Frequently Asked Questions (FAQs)

You can create microservices in Laravel using the Lumen Microservice framework. Lumen is the best choice for creating microservices because it is fast with all features of Laravel. It is easy to scale, and maintain and is ideal for building APIs.

You can create microservices using Laravel Lumen. The laravel microservices is an approach to developing a single application as a suite of small parts accessed through APIs. To access those parts/services the initial layer or the User-app act as an API gateway. The user calls for API gateway URL and is then authorized by the API gateway which then calls the respective service.

The API gateway keeps a service repository, a singleton class that includes service metadata and hostnames which helps in knowing which service to call.

Laravel is neither Monolithic nor Microservice in itself. Instead, Laravel is a free and open-source PHP framework providing a set of tools and resources to build both Monolithic and Microservice architecture-based applications.
