What is Composable Architecture?

Composable architecture is a design approach that enables software systems to be built using smaller, independent, and interchangeable components. These components can be combined in different ways to create different applications, reducing the need for monolithic applications.

Composable architecture is like building with Legos. Instead of one big block, you have many small blocks that you can put together in different ways to make different things. This makes it easier to change and add to what you have built, just like how you can add more Legos to your creation.

And the best part is, you can use the same small blocks to make lots of different things, just like you can use the same Legos to build different structures.

Why is composable architecture important?

A composable architecture is important for a digital technology stack so that it can evolve and grow with your business requirements. If your website is big and complicated, it can be hard to make changes or add new features. With a composable application, your website is broken up into reusable components that saves you time and money.

This design approach allows you to build multiple applications using a core set of interchangeable parts that can be combined in various ways. This means you can create multiple websites, such as knowledge databases and learning management systems, with the same building blocks.

For instance, if you have a core component for user authentication, you can reuse it in multiple applications. Another core component could be a header or card. By reusing these core elements, you can quickly and efficiently develop a composable application without starting from scratch every time.

This makes maintenance and updates simpler as well. If you need to make changes to a core component, those modifications can be reflected in all of the applications that utilize that component, saving time and reducing effort compared to having separate components for each application.

Composable architecture makes managing and developing large and complex software design, easy. By breaking down the system into smaller components, it becomes easier to modify, test, and deploy individual parts, making the software system more flexible and scalable, and ready to adapt to evolving business needs.

Components of a Composable Infrastructure

Composable infrastructure consists of three major components: modular design, services-oriented architecture, and event-driven architecture. Each component contributes to a flexible and scalable digital environment by dividing a project among team members and directing requests like a traffic control system.

Modular Design

Modular design, a cornerstone of composable enterprise architecture, revolutionizes the process of building complex websites by dividing them into manageable, self-sufficient pieces. These modules can be reused and put together in different ways for different purposes. This makes it easier to add new features and less likely that there will be technical problems.

The world of web development has witnessed a proliferation of technologies that make modular design a reality, with ReactJS and Vue at the forefront. These JavaScript libraries grant developers the power to craft reusable UI components, simplifying the creation of intricate and dynamic user interfaces.

With this modular approach, teams can easily make web apps that are reusable, expandable, and long-lasting. This ability to have a dynamic configuration cuts down on development time and makes sure updates go smoothly.

Services-oriented Architecture

Services-oriented architecture, a key component of a composable infrastructure, allows for the division of labor and collaboration like never before.

Imagine building a website: one expert focuses on design, another on great content, and a third on building the functionality.

With services-oriented architecture, each team member can work independently and seamlessly combine their efforts to form a cohesive final product. This approach not only results in faster service delivery but also minimizes the risk of problems arising from changes.

Event-driven Architecture

Event-driven architecture is like having a super cool traffic cop for your website or app. Every time you want to find something, the traffic cop makes sure it goes to the right place, and you get an answer super fast.

Imagine if you wanted to buy a pair of shoes online. When you type in what you want, the traffic cop will send your request straight to where the shoes are, and you'll get your answer immediately. This makes it much simpler to locate items, and it also improves the functionality of the website or app.

What are the Advantages of Composable Architecture

There are many benefits of composable architecture, including increased flexibility, improved efficiency, and reduced development time. Because of these benefits, it's easier and faster to build, maintain, and update websites and apps, and they all have the same quality and consistency.

Increased Flexibility

Composable architecture presents an unparalleled level of flexibility when it comes to constructing and altering digital systems. It allows you to tweak and modify in small sections, similar to putting together building blocks.

This increased adaptability enables you to quickly experiment with new ideas and make changes without expending unnecessary effort or time.

Consider the instance of constructing a tower. With just one large block, transforming its shape becomes a herculean task. But, with several smaller blocks, you can effortlessly modify the shape by simply adding or removing blocks.

Similarly, with composable infrastructure, you can easily make design modifications to your website or app by merely adjusting a few minor components instead of undergoing a complete revamp of the entire structure.

Improved Efficiency

Composable architecture streamlines the process of building digital systems, allowing for a faster and more efficient method of creation akin to putting together a puzzle. When all the pieces of a puzzle are separate, assembly takes longer. 

However, when grouped into smaller sets, the process becomes quicker and easier. Similarly, by utilizing a set of core components that can be combined and reused in different ways, a team can assemble a website or app with ease, thereby hastening the project's completion and maximizing efficiency in meeting deadlines while delivering a top-notch product.

Reducing Development Time

With a composable infrastructure, the development of a website or app becomes more streamlined and efficient, like navigating a well-planned road trip with a map.

The architecture provides a set of reusable and modular components, reducing the time spent on building each project. 

Adding future digital experiences is now a matter of fitting in a few small pieces instead of overhauling the entire structure.

This agile way of developing software gives teams the freedom to be more creative, try out new ideas easily, and meet deadlines while still making a high-quality product.

What are the disadvantages of Composable Architecture

Despite its alluring promise of streamlined and efficient website development, embracing composable architecture is not a bed of roses. This approach brings with it a triad of difficulties - the intricate intricacies of design, the mounting costs of maintenance, and the headaches of quality control. But, do not despair! By partnering with the right team, these hurdles can be vanquished and the benefits of a composable technology can be yours to reap.

Complexity of Design

The use of composable architecture can be slowed down by design complexity. With numerous pieces needing to come together seamlessly, the design process can prove to be a challenge. However, by embracing the concept of modular design, this complexity can be reduced.

The modular design breaks down the system into smaller, easily manageable modules, making it easier to comprehend the workings and troubleshoot any issues that arise. Building a design system that can be used more than once from scratch, on the other hand, can take a lot of time and requires careful planning and the skills of a skilled design team.

Cost of Maintenance

A potential pitfall of implementing a composable infrastructure is the heightened cost of maintenance. Keeping a composable infrastructure in tip-top shape can be more expensive than maintaining a conventional, all-in-one setup, as every piece must be individually tended to.

However, this drawback may be mitigated by using a services-oriented approach, which makes it possible for individual experts to maintain and upgrade particular components without affecting the overall coherence of the system as a whole.
