The Mendix low-code app development platform enables you to build responsive and scalable faster and more efficiently. However, robust architecture and design patterns are the foundation of building such successful apps with Mendix. These elements include everything that defines your application, from data logic and user interface/ user experience (UI/UX) to development processes and tech stacks.
Specific app architectures are code-intensive, need advanced skills, and are more difficult to test and maintain than others. Fortunately, Mendix provides a clearly defined architecture framework and multiple design patterns to help you accelerate enterprise app development and create first-class experiences that meet your business requirements and user expectations. But what design patterns should you consider when designing your Mendix app’s architecture? Let’s find out.
Here are some top design patterns to consider when designing a Mendix app architecture:
Microservices architecture is a famous design pattern for developing complex apps, and it is particularly helpful in building responsive and scalable applications with Mendix. This architecture is based on the divide and conquer concept. It involves breaking down a large app into smaller, independent services that can communicate with one another via Application Programming Interfaces (APIs). Each of these services has unique functionality; you can build and deploy them independently.
This design pattern offers various benefits, including the following:
Scalability is one of the main benefits of the microservices design pattern. Each service can be scaled up or down as required without affecting the other services because it is self-contained and runs independently. This simplifies managing high traffic volumes and guarantees that the application will function well and remain responsive even during peak usage.
Another advantage of the microservices design pattern is flexibility. This architecture enables you to select the best technology stack for each service and update or replace specific services without affecting the application as a whole. Therefore, it makes development and deployment cycles move more rapidly and facilitates faster adjustment to shifting business requirements.
Finally, improved resilience is another benefit of the microservices design pattern. Since each microservice runs independently of the others, it minimizes the risk of total application failure. The other services can keep running even if one fails, guaranteeing that the application as a whole continues to function and is accessible to users. Therefore, microservices architecture is a robust design pattern for building responsive, flexible, scalable, and resilient apps with Mendix.
The event-driven architecture (EDA) design pattern helps you create scalable and responsive applications with Mendix. This design pattern is based on events and their handlers, which process and react to events in the system.
In EDA, events are the things or changes that happen within an application or its environment. Events can be user activities, system updates, or modifications to external data. One or more event handlers are activated when an event occurs. These handlers are responsible for processing the event and taking necessary steps. For instance, they can do various tasks, including updating UI, processing data, and sending alerts, among other things.
So, what are the benefits of the EDA in building responsive and scalable apps with Mendix? Let’s find out.
This design pattern offers several benefits, including the following:
Since your Mendix app will be built around events with EDA, it becomes more reactive and can manage multiple events concurrently. Therefore, it can respond quickly to user requests, changes in the environment, and system updates.
This design pattern decouples your Mendix app’s components, making it easier to scale individual elements independently. As a result, it enables your Mendix app to effectively handle high traffic volumes and guarantees responsiveness and performance even during peak periods.
Since the EDA design pattern involves designing your Mendix app around events and handlers, you can easily add new or modify existing handlers as your requirements change. As a result, it enables rapid development and deployment cycles and facilitates faster response to changing business needs.
The Model-View-Controller (MVC) design pattern is commonly used for creating applications, including those built with Mendix. It separates an application into three interconnected components: the model, view, and controller.
The model handles the data and business logic, the view handles the user interface, and the controller takes user input and updates the model and view. This separation of concerns improves the maintainability and extensibility of an application by making it easier to modify individual components without impacting others.
The command query responsibility segregation, abbreviated as CQRS, separates the read and write operations of your Mendix app. This allows for scalable and more efficient data access. While write operations are managed by the command layer, read operations are handled by a different query layer. By separating the read and write operations, this design pattern allows for more optimized data retrieval and storage and improved scalability and performance, as each function can be scaled and maintained independently.
This design pattern lets you model your Mendix app’s domain to reflect your company’s understanding of it. It emphasizes collaboration between developers, domain experts, and other stakeholders to develop a common understanding of the domain and create a model that perfectly reflects it.
As a result, it helps develop a shared language and domain understanding, allowing developers to build more responsive, scalable, and effective apps with Mendix. Also, it promotes code reuse and boosts app maintainability as it creates a clear separation between the domain model and the implementation of technical details.
Strong architecture and design patterns are key to building a successful, responsive, scalable app with Mendix. Therefore, it’s crucial to assess the available design patterns, capabilities, and concepts and choose the best fit for your business requirement or application use cases. Doing so will help you build a scalable, efficient, and responsive Mendix app that adapts seamlessly to changing business requirements over time.
