Benefits can be achieved by transitioning from a monolithic application to Ruby on Rails microservices in today’s ever-evolving business landscape and the need for rapid software development.
Microservice architecture in Ruby on Rails facilitates quicker deployment while also enhancing scalability, maintainability, and adaptability.
The advantages of switching from a monolithic to a Ruby on Rails microservices architecture are discussed in this article.
By reading this article, you will be equipped with the necessary information to make an informed decision on whether or not to implement a microservices architecture.
Microservices in Ruby on Rails: What Are They?
Ruby on Rails is a framework which utilizes the Microservices application architecture. This methodology breaks down larger applications into smaller, more manageable services which communicate with one another through Application Programming Interfaces (APIs). Each service operates independently in its own process and interacts with the rest of the system through predefined interfaces and lightweight mechanisms, often utilizing HTTP APIs.
Tools like Docker and message queues like RabbitMQ can be used to put Ruby on Rails microservices into action.
Ruby on Rails is highly suitable for the development of microservices, due to its extensive availability of established standards and tools which enable swift building and deployment of web applications.
Is it possible to explain the concept of a “monolithic” Rails app?
A single, huge Rails app that includes a whole web app’s worth of code, resources, and functionality is known as a monolithic Rails app.
This application is developed using the Ruby on Rails web platform. Ruby on Rails makes developing and maintaining web applications easier than ever before.
Monolithic programmes cannot quickly scale since all of its components are dependent on and strongly tied with each other.
Which Is Better, a Big, Monolithic Rails App or Lots of Small, Independent Ruby on Rails Apps?
Ruby on Rails microservices vary significantly from monolithic Rails apps in many crucial respects:
| Factors | Ruby on Rails Microservices | Monolithic Rails Applications |
|---|---|---|
| Scalability | Microservices make it easier to scale different parts of your application separately. | In a monolithic application, scaling the entire application can be more difficult because all parts of the application are tightly coupled. |
| Architecture | Microservices are divided into smaller, modular services. | Monolithic applications have a single codebase. |
| Deployment | Independent deployment is the key to Microservices. | Monolithic applications are deployed as a single unit. |
| Resilience | Microservices can continue to function if one service fails, resulting in a more resilient system. | If a monolithic application fails, the entire application may fail. |
| Flexibility | Microservices allow for more flexibility by enabling changes to individual services. | It is difficult to make changes to a monolithic application. |
| Reusability | Microservices can be reused in other projects or applications. | Monolithic applications are generally not reusable. |
Microservices framework based on Ruby on Rails
Ruby on Rails is a full-stack framework offering programmers access to a range of resources such as tools and libraries to aid in developing web applications.
Ruby on Rails’ preference for convention over configuration is a great advantage when it comes to developing microservices. Its standardized rules for file names, directory organization and code style make creating and maintaining microservices much more efficient.
Ruby on Rails also offers a variety of tools and frameworks that may be used to the development of microservices, including as
ActiveRecord:
A database library that offers an ORM layer for storing and retrieving data.ActionPack:
A collection of resources for creating web applications, including as view controllers, view models, and route handlers.ActiveSupport:
A collection of classes and methods designed to streamline development of Ruby on Rails applications.
A Guide to Implementing Ruby on Rails Microservices. Give an example using Ruby microservices to clarify.
Here’s what you need to do to integrate microservices built on Ruby on Rails into your app:
Find the pieces of the programme that may stand to be separated:
Finding the different parts of a program that can be separated out into their own services is the first step in adopting microservices.
Envision a single Rails application that manages everything from product cataloguing to payments. To maximize the benefits of this framework and construct efficient applications, such as Airbnb, it may be beneficial to separate certain components into their own microservices. Professional Ruby on Rails developers can be employed at competitive rates to assist in this endeavor.
Cartographically confine the microservices:
Determine the inputs, outputs, data, and functionality for which each microservice is accountable once you’ve identified the decoupling components.
To demonstrate, the microservice responsible for a customer’s shopping cart can be used for adding and retrieving products. It is conceivable that the microservice payment gateway is responsible for handling financial transactions.
Take out the microservices’ source code:
Once the boundaries of the microservices have been established, the required code can be extracted into new codebases. The process of restructuring the code involves making the modules independent and operating as expected.
It would be possible to separate the code for the shopping cart feature into its own repository, and then upgrade it to make use of an API to communicate with the payment gateway and product catalogue microservices.
One possible way to split out the cart checkout process into its own microservice is as follows:
Get the microservices’ foundations set up:
Deployment pipelines, monitoring, and logging should all be implemented as part of the microservices’ supporting architecture. The process involves creating and configuring individual environments for each service and the underlying infrastructure.
The microservices’ testing and release:
The subsequent actions are service deployment and testing.
It entails preparing integration tests to guarantee the services function as intended, then delivering such services to the live environment.
Microservice design
Microservices architecture is a methodology that enables the development and deployment of systems composed of multiple services. These services interact with each other by using predefined interfaces.
Each service in a microservices-based architecture handles a distinct task and is independently deployable and scalable.
Ruby on Rails Restful API
HTTP enables Representational State Transfer (REST) APIs to facilitate communication between different computer programs. REST APIs are easy to use and comprehend as they follow a standard protocol for sending and receiving requests.
Ruby on Rails is a popular web development framework often used to create REST APIs. To do so, there are several steps to be taken:
Create a fresh Rails application:
To start, you can use the ‘rails new’ command to generate a new Rails project. This will place all the necessary files and folders for your project into a new folder.
You must provide the API endpoints:
The next step is to provide the API’s points of entry. One or more controllers must be developed to manage the various API requests.
For requests about user administration, you may develop a UsersController.
Put the API Logic into action:
Once the endpoints for your API have been specified, the logic must be implemented. To achieve this, it will be necessary to implement logic in the controllers and models to process the various requests that your API will accept.
Make sure your API works:
Once you have completed development of your API, it is advisable to test it to ensure that it is functioning as intended. Utilize tools such as Postman or cURL to send queries to your API and ensure that it is responding correctly.
Put your API to use:
Once you have completed testing and are satisfied with the performance of your API, it can be deployed to the production environment. It is only when it is deployed that it will be available for your customers to use.
In general, Ruby on Rails’s robust set of tools and frameworks makes it easy to construct a REST API.
How to authenticate across Rails microservices
Careful planning of authentication and authorization within a Rails microservices architecture is essential. When using a microservices architecture based on Rails, there are a variety of approaches available for managing authentication.
Put to use a consolidated authentication system:
User credentials may be stored in a database and the service can be constructed using a framework such as Devise. Subsequently, microservices could submit authentication requests to the centralized service.
The Use of JSON Web Tokens (JWTs):
JSON Web Tokens (JWTs) are self-contained tokens that contain information about a user, such as their user ID and rights. They can be utilized for authentication in microservices by including a JWT in each request and verifying its validity on the server.
The Use of OAuth:
OAuth is a widely recognized protocol allowing users to grant third-party applications access to their resources without needing to share their passwords. Through initial authentication with a third-party service (such as Google or Facebook), users can then authorize the use of these services by microservices. This is the purpose of OAuth.
Frequently Asked Questions About Microservices Built with Ruby on Rails
Explain what microservices are.
Microservices are a type of software architecture which enables an application to be divided into a set of smaller, decoupled services which share a common Application Programming Interface (API) for communication. Each service carries out a distinctive task and may be developed, tested and deployed independently from the other services.
Can you explain what it means to have a “microservice architecture”?
A microservice architecture is characterized by the use of numerous small, independent services that form a larger application. Communication between these services is typically achieved through the use of Application Programming Interfaces (APIs), with each service designed for a specific purpose.
By separating a large program into more manageable pieces, this design hopes to increase the app’s adaptability, scalability, and maintainability.
Why develop microservices using Ruby on Rails?
