Dynamic business and user demands combined with technological advancements have created a growing app development landscape. Moreover, vulnerability to rapid and unexpected changes has forced businesses to find ways to increase organizational flexibility and adaptability and continuously improve themselves to remain afloat and grow even under challenges.

Composable applications transform enterprise IT and help companies adapt to the digital environment by improving productivity, scalability, and streamlining business operation processes. They efficiently deliver quality-based reusable applications you can optimize and re-deploy quickly to meet customer expectations. 


By 2028 the global composable infrastructure and applications market will reach $14.35 billion. The composability systems design approach increases agility and accelerates application development, helping organizations reuse and re-assemble existing assets uniquely for improved data collection, use, and analysis and satisfy distinct user requirements.

Next-gen enterprise applications will be composable, scalable, with integrated speech and video capabilities, and powered by the latest technologies. If you’d like to maximize existing resources and meet diverse, constantly changing business demands, here’s everything you need to know about composable applications.

What are composable applications?

They’re a modern business-centric design approach to developing software with independent, interchangeable building blocks or modules. They’re built around application programming interfaces (APIs) and microservices, enabling app communication and increasing business efficiency. 

Composable apps help organizations reuse interchangeable, functional pieces of code from existing applications and bundle them together, to build and modify existing applications or create larger, more complex apps with more features and utility.

Composable applications use modular, innovative, and adjustable solutions to repurpose functional individual processes or application pieces. With these detachable pieces, businesses can build more robust applications with improved functionality.

Benefits of adopting composable applications

Faster rollout of features

By updating existing app components rather than the entire app, composable apps enable developers to accelerate development than if they started building from scratch. Developers can launch features and updates faster by building and testing smaller, independent components rather than large, fossilized applications.

Composability provides a plug-and-play architecture that helps organizations pool resources, dismantle, swap, and re-assemble components quickly to match the fast-paced nature of business transformation.

Enhanced flexibility and agility

Composable apps help businesses become more innovative, resilient, and agile, so they can outpace their competition by up to 80 percent. Composable apps are easy to customize and reconfigure to meet ever-shifting customer needs and market changes. Organizations can adjust the size or capacity of these apps as needs arise without affecting their performance and reliability.

Businesses can swap out various composable applications to control app elements and change the functionality of their software system.

Improved efficiency

Pre-built components in composable apps can be easily combined, enabling businesses to develop custom applications more effortlessly. The apps’ modular design reuses code, so app development and maintenance require less time and effort, improving organizational efficiency.

Modular architecture helps businesses create, update or modify without disrupting the entire system, minimizing downtime and increasing efficiency. There are fewer code errors as standalone composable app components are extensively tested.

Reduced costs

By reusing existing composable app components, organizations can minimize the need for costly custom app developments and over-reliance on external third-party vendors. They also lower the expenses of hiring developers to build apps or maintaining a large IT team to rewrite existing code. Less skilled developers can also configure composable app components because there’s no need to understand the whole application.

Organizations can break down large applications into configurable puzzle pieces and plug pieces elsewhere to save time and money on development processes and timelines.

How do composable apps work?

Composable applications are practical, valuable building blocks for any business process. Their unique, separate pieces decrease the functional complexity of traditional development processes and help organizations develop new, more competent applications on-demand or improve the functionality of existing applications efficiently.

Composable applications' plug-and-play architecture enables organizations to pool resources and increase their innovation capabilities to become more flexible and resilient. With such applications, businesses can easily dismantle larger, more complex components and then adapt them to meet changing business requirements. 

Since composable apps are loosely paired, they're easy to reuse and integrate seamlessly with multiple existing applications and systems. The composable architecture includes well-defined APIs that offer connectivity to independent components, making them composable and easily accessible over the cloud.

4 principles for evaluating enterprise composable readiness


Effective enterprise composability involves constructing and coordinating parts of an enterprise's apps, processes, and infrastructure to meet specific demands. To determine an organization's ability to meet complex digital business demands, use these four key principles:

1. Modularity


Organizations can achieve enterprise composability by adopting modularity as a core principle. Modularity breaks down complex IT infrastructure into smaller, more manageable, and reusable building blocks, easy to construct, dismantle, and re-assemble to create new applications.

With microservices and APIs, modularity improves application agility by packaging certain services into Packaged Business Capabilities (PCBs) ideal for a specific purpose.

2. Discoverability


Composable readiness enables various business components to work seamlessly regardless of the organization’s technology stack. In a composable business system, all team members should be able to find and reuse existing components to create new solutions.

A central record with sufficient descriptions and metadata to describe an application’s purpose and limitations significantly improves development speed. 

3. Autonomy


Autonomous individual components heavily support enterprise composable readiness. Fully self-sufficient components independent of other system parts help developers detach from the complexity of legacy infrastructure, allowing them to focus on building applications faster.

This way, teams across the organization can update parts of the system without disrupting others, making apps far more resilient to changes.

4. Orchestration


Higher-order automation digitizes business processes and aligns workflow to match business goals and resources. Automation simplifies and streamlines the creation, testing, and deploying of software components, which minimizes the risk of errors and quickens the speed and reliability of app delivery.

Orchestration eliminates manual, time-consuming, and repetitious tasks, lowers costs, increases productivity, and helps businesses provide reliable service.

Building blocks of composable apps

  • Composable thinking: It's behind the idea anything is composable. It fosters a responsive, more flexible way to design principles that guide organizations on what to compose and when to meet rapidly changing customer needs. Composable thinking encourages creativity and involves seeking and sharing information internally and externally.
  • Composable business architecture: It includes capability, engagement, and technology. Each component has standardized APIs or interfaces to increase organizational flexibility and resilience, with unique business design mechanisms. Composable business architecture helps businesses develop a digital acceleration model to identify and implement changes capitalizing on digital transformation benefits.
  • Composable technologies: They boost connectivity, reusability, and transparency across the organization. Adopting a robust tech foundation supports composability, which increases business agility and flexibility. The four principles of composable readiness act as product design goals to drive technology and promote composability, execution consistency, and faster response time

Don’t know how to code? You can still build apps without depending on IT.

How leveraging low-code platforms helps build composable business apps better

Organizations are increasingly turning to low-code for highly customized automation to fulfill growing app demands and accelerate development. Low-code app development platforms increase business agility, enabling businesses to change their composable apps and respond better to evolving business demands. 

Low-code platforms are the perfect development platform for businesses to build composable apps.
