Future-Proof Your Digital Products Through Agility and Adaptability With Composable Architecture

In the constantly evolving digital landscape, leaders are on the lookout for effective and innovative means to drive their enterprises forward. In the world of web, app and other bespoke digital products, amidst the myriad of options, Composable Architecture is gaining recognition as one of the leading approaches for achieving digital product excellence.

What is Composable Architecture? Why is it making waves? How can enterprises effectively adapt, adopt and implement it in the making of digital products and delivery of exceptional digital experiences? Let’s take a closer look.

What is Composable Architecture

Composable Architecture is a design approach for constructing digital systems using smaller and self-contained modules (e.g., microservices, headless apps, SaaS and serverless functions) that can be independently developed, managed and/or updated. These modules maintain their distinct characteristics while seamlessly integrating with each other, resulting in a cohesive and synergistic blend of functionalities.

Composable Architecture VS Traditional Approach

Driven by the emergence of API and SaaS, Composable Architecture enables your business to design and build digital products that are not only resilient and high-performing but also with greater efficiency and speed compared to the traditional approach.

Traditional structures adopt a consolidated approach, welding all functionalities into a single and intricately connected system. While it is less costly and requires less time and resources initially, when demands and requirements shift or increase, and there’s a need to adapt and change, even minor adjustments may necessitate extensive system-wide overhauls.

Furthermore, as your traditional system expands and evolves, these challenges compound and accumulate more technical debt over time, making it increasingly challenging and costly to introduce new features or adapt to shifting business demands.

For small and medium-sized enterprises (SMEs), commencing with a traditional approach may be more financially viable. However, this paradigm does not align with the strategic imperatives of larger enterprises, where the scale and complexity of operations demands a more sophisticated architectural approach.

Why Composable Architecture

As mentioned, the ability to swiftly respond to shifting customer needs and market demands holds immense value. Composable Architecture offers an agile framework for making adjustments and fostering innovation, all without the need for substantial changes. The good news is that there is more to this:

• Adaptability – it provides the flexibility to adapt quickly to changing market conditions and customer needs by staying nimble in a fast-paced market.

• Cost control – it enables cost control by allowing targeted and independent adjustments and enhancements. It prevents the need for costly, full-scale system redevelopments, making efficient use of your budget.

• Ecosystem integration – it facilitates integration with partners, suppliers and other ecosystem participants. It also has successfully accommodated existing Customer Relationship Management (CRM), Event Management Systems (EMS) and other platform types at a much lower cost.

• Future proofing – building an adaptable architecture ensures long-term relevance by easily incorporating emerging technologies and trends. This future-proofing strategy allows you to remain competitive and adaptable in a constantly evolving business landscape.

• Innovation – it fosters innovation by providing a framework for integrating cutting-edge technologies and third-party services. This encourages experimentation and the incorporation of new tools and capabilities that can differentiate your offerings.

• Efficiency – efficiency in development and deployment reduces time-to-market for new features and products. This benefit streamlines processes, saves resources, and enhances profitability by delivering value more quickly.

• Reduced risk – it reduces the risk of system-wide failures or disruptions by allowing updates or replacements of individual components independently, meaning if issues arise, they can be isolated to specific components, minimising their impact on the entire system.

• Reduced technical debt – it often incorporates SaaS-based product offerings, which bring their own management and patching capabilities. This integration significantly reduces the reliance on IT teams to oversee and manage patching across all systems.

• Scalability – it improves your systems’ ability to handle increased workloads and accommodate your business expansion seamlessly. Much like spreading investments across a diversified portfolio. This approach helps ensure that no single component bears an excessive burden, promoting system stability and optimal performance even during high-demand periods.

• Compliance and security – by isolating and securing individual components, Composable Architecture helps maintain compliance and keeps your digital assets secure. This benefit is essential in sectors with strict data protection requirements.

• Improved customer experience – the ability to modify components allows for the creation of exceptional, personalised digital experiences. Its components can be tailored to address distinct customer needs. This heightened level of customisation and responsiveness contributes to improved customer satisfaction and loyalty.

The “how”: a step-by-step guide

So far, we have gained insights into the ‘what’ and ‘why’ of Composable Architecture. Now, it’s time to delve into the practical ‘how’. Transitioning to Composable Architecture can be both a daunting and exhilarating experience. Yet, with the right strategy, it becomes as smooth as the architecture itself. While each project is unique, the following steps serve as a prudent starting point for delineating your strategy towards embracing Composable Architecture.

Step 1: Preparation

Before transitioning to Composable Architecture, start with a comprehensive audit of your current digital systems.

• Evaluate your current IT landscape and thoroughly understanding your existing architecture, systems and technologies is vital.

• Identify the business capabilities of the system and assess which are currently available. Take note of those that are not available.

• Identify the components of your existing system that can be modularised or decoupled. These may include APIs, microservices, databases and front-end applications.

• Establish new components that need to be added to deliver the required business capabilities.

• Assess your organisational readiness. Ensure that your team possesses the requisite skills and expertise needed.

Step 2: Goal setting

Clearly define your business objectives and goals for transitioning to Composable Architecture. Develop a phased roadmap for the transition. Break the journey into manageable stages, each with its set of goals and milestones. This approach allows for gradual implementation and risk mitigation.

Step 3: The “team”

Establish a team and if necessary, consider providing training and upskilling opportunities, and partnering with experts from the outside to lead, support and facilitate a smoother transition.

The composition of a team for a typical transformation project may vary based on factors such as the project’s unique characteristics, the industry it pertains to and the scale of the organisation. Having said this, there are some key roles that are commonly found in a transformation project team:

• Enterprise Solution Architect

• Business Analyst

• Cloud Solutions / DevOps Engineer

• Product Owner

• Senior Engineers

• Quality Assurance / Automation Engineer

• Project Managers

In addition to acquiring the necessary human resources, it’s essential to invest in the right technologies and software solutions that support the successful implementation of Composable Architecture. For example, the MACH framework is a good option. MACH, which stands for Microservices, API-first, Cloud-native, and Headless, advocates the adoption of:

• Microservices to modularise applications

• An API-first strategy to ensure seamless connectivity and integration

• cloud-native infrastructure to enhance scalability and resilience

• Headless content management for efficient content distribution across various channels

Step 4: Adoption and Transition

There is no doubt Composable Architecture will bring numerous benefits to your enterprise, and while it is exciting, it can also be daunting and comes with several challenges. For example, managing technical complexity, ensuring seamless integration, addressing data security and compliance, navigating change management and dealing with resource constraints.

Therefore, consider starting small, with pilot projects to validate the new architecture in real-world contexts. They will serve as valuable testing grounds for refining processes and addressing any challenges that may surface.

Step 5: Gradual implementation

Take a gradual scaling approach and focus on continual refinement and optimisation, drawing insights from valuable feedback:

• Begin by identifying additional components or systems suitable for the modular approach, prioritising comprehensive testing and validation, and then deploying them incrementally.

• Establish feedback mechanisms for continuous improvement and optimise the structure and scale resources.

• Document changes, maintain stringent security measures, implement backup and recovery strategies, and ensure compliance and governance.

• Monitor performance metrics and conduct load testing.

This ensures a systematic and technically sound scaling process while addressing potential challenges and optimising performance throughout the implementation journey.
