How do OutSystems build composable applications?

When building composable applications with agile methodology, OutSystems low-code platform can turn your innovative ideas into enterprise-grade applications. 

In this blog, we will learn about low-code composable applications, why you should invest in business composability, how to transform your business into a composable enterprise, and the key capabilities of the OutSystems platform supporting composable applications. 

What are low-code composable applications? 

A composable enterprise focuses on creating an application architecture wherein enterprises can deliver various functions via microservices modules instead of a monolithic system. As most organizations are moving towards digital transformation to improve their business outcomes, keeping up with the pace of app development is important.

OutSystems low-code composable applications are a set of independent, reusable code blocks independent from each other that come together to create new applications. In other words, it is a group of off-the-shelf products linked with APIs for communications.

Why should you invest in an enterprise low-code composable platform? 

From a business perspective, low-code composability gives organizations the agility to react, respond to market changes, and adapt faster to external and internal factors like changing customer requirements overnight. When each organization owns and manages individual PBCs (Packaged Business Capabilities), productivity increases immensely as they don’t have to start developing from scratch. Each PBC, module, or service a developer creates, be it a function call, logic flow, or database, will be reused in other applications boosting their productivity and the quality they achieve.

The four principles of business composability

Gartner has introduced four principles that guide business composability: 

  1. Orchestration: Provides you with better leadership in prescribing and negotiating interactions between components and enables recomposition and forming processes. 
  2. Modularity: Enables greater agility partitioning a domain into managed components to scale and control change. 
  3. Discovery: You can get more speed to discover and understand design opportunities and components to guide, track and, secure change. 
  4. Resilience: Autonomy can minimize dependencies of components from each other to maintain the integrity of change.

The three pillars of business composability pillars

Business composability also impacts people and processes. Therefore organizations need to consider three pillars of a composable enterprise. 

  1. Composable thinking: It involves people who conceptualize what to compose and when, encouraging continuous exploration of business capabilities. 
  2. Composable business architecture: It involves processes involving capabilities, products, services, teams, etc. 
  3. Composable technologies: It involves choosing the right technology that promotes modular components, reusability, and automation.

How to transform your business into a composable enterprise? 

When it comes to choosing the right technology, low-code platforms like OutSystems support composable applications with the appropriate architecture, components, agility, advanced UI/UX, and security. Here we will talk about the Packaged Business Capabilities OutSystems offers that transform your business into a composable enterprise:

  • End-user services: Provides screens, UI blocks, and capabilities to deliver end-user interfaces. 
  • Core services: Summarizes the business logic to complete the processes. 
  • Foundation services: Contains reusable UI patterns, APIs, plugins capabilities to handle integrations. 
  • Integration services: Handles external events that need to trigger with some PBC functions. 

Key capabilities of OutSystems that support composable apps 

Composable business architecture intends to delegate the authority and ownership of the PBCs to smaller teams and gain agility. The OutSystems platform provides composability, reusability, communication, and collaboration. Let’s discuss the key capabilities of OutSystems supporting composable applications: 

#1. Rapid Application Development

With the fundamental shift in customer expectations, business agility is referred to as one of the leading digital transformation attributes. Therefore, rapid application development is the idea that benefits building composable applications. OutSystems enables rapid app development via dynamic scaling, automation, performance monitoring, user management, version control, and more. Let’s discuss the following features that help in delivering applications with speed:  

  • OutSystems allows businesses to create applications using a visual drag-and-drop approach and has many pre-built components that cover unique business requirements. It allows you to easily make customer-facing applications with rapid development. 
  • OutSystems automates connections to back-end services such as data structures and storage, allowing developers to do more productive work building enterprise-grade applications.
  • With OutSystems, you can create core experience components like payment gateways, bookings, add to cart, etc., using a single platform and technology and deploy them across multiple channels. 

#2. Increased collaboration between business and IT 

Visual-model-driven development is at the core of the OutSystems platform to provide fast, right, and future applications reducing costs and risks by enabling continuous development across all platforms. Visual solutions simplify business process complexities of traditional app development, increasing collaboration across departments. 

  • OutSystems Workflow Builder can visually map complex business processes and automatically build high-performance, workflow-based apps. 
  • OutSystems Experience Builder allows rapid prototyping of user-friendly mobile applications that leverage common patterns and flows.    
  • OutSystems lets you develop with a visual module while retaining complete flexibility to integrate custom code, enabling extensibility, efficiency, and accelerated development. 
  • The visual-driven approach requires no runtime interpreters or engines are required to enable OutSystems applications. The platform generates applications with a standard architecture. 
  • The visual application models designed with OutSystems are compiled into standard, well- architectured, and optimized code like JavaScript, HTML, CSS, C#, and Standard SQL. 

#3. Innovative architecture

OutSystems modular architecture, you can create applications that enable organizations with pre-built modules that can be deployed, combined, and reused as needed in order to quickly build new solutions. These multi-module solutions eliminate developer or development lifecycle conflicts. Some of the key features that innovate app development are:

  • With the modular architecture of OutSystems, multiple developers can work in separate modules with the confidence that their work will not affect others. 
  • All the versions of applications and modules are stored and can be reused like pre-built modules composed for business users. 
  • The OutSystems Forge is the largest marketplace of reusable, open-code modules, connectors, UI components, and business solutions. More than 5000+ pre-built templates have helped speed up application delivery time. 
  • OutSystems architect a modern, automated, and interconnected internal application ecosystem all to overcome legacy application shortcomings and drive greater efficiency. 

#4. Reusable components

Reusable components make app development easier and faster with a modular approach. You can deploy core experiences in minutes using pre-built themes, plugins, templates, and components. Let’s look at some capabilities of OutSystems that ensure building reliable applications at scale: 

  • OutSystems provides you with reusable components in the development environment to enhance the application-building process and deliver scalable and smooth-functioning apps. 
  • With the OutSystems code reusability feature, you can create applications with lightning speed by reusing code blocks previously developed. It is a cost-effective solution for businesses.
