A Brief History of Digital Systems

With technical advancement on the infrastructure layer. let’s draw parallel advancement with general Digital Architecture.

Architecture History

Monolithic Systems

In the earliest days of software, we had monolithic systems. A single codebase governed everything, from the user interface to business logic and data access. While this approach made deployment easy, it was inflexible. Changes to one part often required altering other parts, making scaling and maintenance challenging.

Tier Architecture

This model divided software into three layers: presentation, logic, and data. This separation allowed teams to work on different layers independently, offering better scalability than monolithic systems.



A further evolution came with the introduction of microservices, where software was split into independent services that communicated over the network. This architecture offered even more flexibility and scalability but required robust network infrastructure and management.

Serverless and Function-as-a-Service (FaaS):

These paradigms further abstracted infrastructure concerns. Developers focused solely on writing functions, while the underlying platform managed everything from resource allocation to scaling.

Strong Link to Agility

Agility in the software world refers to the ability to adapt and respond quickly to changing conditions. Composable architecture, by its very nature, champions this agility:

  1. Quick Iteration: Since each module can be developed, tested, and deployed independently, teams can iterate rapidly.
    2. Flexibility in Design: Organizations can mix and match components based on evolving requirements.
    3. Efficient Resource Utilization: Resources can be allocated dynamically based on the demand of individual components, leading to cost savings.
    4. Future-Proofing: As new technologies and modules emerge, they can be easily integrated without overhauling the entire system.

As we reflect on the evolution of the digital architecture, it’s clear that these advancements have also laid the groundwork for the future. Composable Architecture, with its focus on flexibility, scalability, and adaptability, stands at the forefront of this digital architecture.

What is Composable Architecture?

In its essence, composable architecture is about breaking down applications into modular, interchangeable, and reusable pieces. Each module, or “composable unit,” can be combined with others to create tailored applications. The advantage here is clear: rather than building from scratch or trying to customize monolithic applications, businesses can “compose” applications using pre-made modules at the image of Mr. Potato Head that can be customized to suits needs.

Features of Composable Architecture:

1. Modularity: Each component is self-contained, enabling independent deployment and scalability.
2. Interoperability: Components can easily interact with one another, regardless of where they are deployed.
3. Reusability: Components can be reused across multiple applications or even across multiple organizations.
4. Rapid Deployment: New solutions can be quickly composed using existing modules.

Benefit of Composable Architecture

The benefits of such an architecture include:

  1. Flexibility: Components can be added, removed, or replaced without disrupting the rest of the system, allowing for easy adaptation to the changing needs of a business.
  2. Reusability: Components can be designed to be reused across different contexts or applications, reducing development efforts and costs.
  3. Development Efficiency: By isolating functionalities in separate components, teams can work more independently and in parallel, thus reducing dependencies and conflicts.
  4. Simplified Maintenance: Updates can be made on individual components without the need for a complete system overhaul, simplifying maintenance and reducing the risks associated with changes.
  5. Scalability: A composable architecture can adapt to increasing workloads simply by adding new components or enhancing existing ones.
  6. Interoperability: Components designed to be interoperable can work with a variety of platforms and technologies, facilitating the integration of heterogeneous systems.
  7. Resilience: If one component fails, the rest of the system can often continue to function. Also, it’s easier to build redundant or high-availability systems.
  8. Cost Optimisation: By utilising standardised components, companies can reduce licensing costs and avoid vendor lock-in.
  9. Better Risk Management: Replacing or updating individual components can reduce the risk associated with introducing new technologies or relying on outdated systems.
  10. Customisation: Systems can be quickly tailored to meet specific customer needs or market demands without having to reinvent or develop new solutions from scratch.
