The Promise and Reality of Composable Architecture: Bridging the Gap Between Vision and Implementation
Insights from Gene De Libero, Principal Consultant of Digital Mindshare LLC, presented at Digital Experience Assembly (DXA) 2025
“Composable architecture” isn't just another tech buzzword—it's become the North Star for companies desperate to break free from rigid digital experience platforms. As businesses struggle to meet customer expectations, this modular approach to building tech stacks has gained serious traction among forward-thinking digital leaders. Yet, as highlighted by industry expert Gene De Libero at the Digital Experience Assembly (DXA) 2025, there exists a significant tension between the theoretical promise of composable architecture and the practical challenges of implementation.
The Vision vs. Reality Gap
De Libero doesn't mince words when calling out the industry's blind spots. "Analysts are all over this API-first architecture as the future of digital experiences," he told the DXA crowd. "I think composability and modularity are super important... but analysts often underestimate this idea of practical implementation."
His point hits home for anyone caught between boardroom strategies and technical realities. While thought leaders champion these modular approaches from conference stages, the folks in marketing and IT trenches are left figuring out how to make these fancy systems play nice with their existing tech stack, often built up over decades and not designed with APIs in mind.
Gartner claims companies embracing composability will roll out features 80% faster than competitors. Sounds great in a slide deck. But talk to the developers and integration specialists wrestling with implementation, and you'll hear a different story. They're not questioning the destination—just how rocky the journey really is.
What Is Composable Architecture?
At its core, composable architecture represents an approach where digital experiences are built using independent, modular components that are selected from various vendors and integrated via APIs. This API-first model allows organizations to mix and match best-of-breed components rather than committing to monolithic platforms.
The approach follows MACH principles (Microservices-based, API-first, Cloud-native, and Headless), enabling businesses to pivot to new technologies and adapt to market shifts without disrupting operations.
The Three Perspectives: Analysts, Buyers, and Vendors
De Libero identifies three key constituencies in the DXP landscape, each with different priorities:
- Analysts focus on shaping market vision and predicting technology evolution. They view composable architecture as a strategic evolution essential for future-proofing technology stacks.
- Buyers (marketing and IT professionals) are primarily concerned with solving practical problems and maximizing the value of their investments. They prioritize integration, usability, and clear ROI.
- Vendors aim to drive innovation while securing market dominance. They're racing to implement new features, sometimes at a pace that outstrips buyer readiness.
"There's tension here," explains De Libero. "Future versus present. Innovation versus practicality. We have three different players, and they're all pulling in different directions."
The Implementation Challenges
While the vision of composable architecture is compelling, several practical implementation challenges persist:
1. Integration Complexity
Integration issues represent one of the most significant barriers to composable architecture adoption. According to De Libero, approximately two-thirds of buyers prefer a multi-vendor approach but struggle with connecting systems and making them work with existing technology investments.
Legacy systems rarely disappear overnight, and organizations must maintain complex integration patterns between new modular components and established technologies. These integrations require specialized knowledge and careful planning.
2. Skill Gaps
Let's be honest: most IT departments weren't built for this. The technical chops needed to make composable architecture sing simply don't exist in many organizations. We're talking about a massive leap from the comfortable world of monolithic systems to one where your team needs to juggle API management, wrangle microservices, and navigate cloud-native development—all while keeping the business running.
It's like asking someone who's spent their career driving cars to suddenly pilot a helicopter. Sure, they both get you from A to B, but the skill set? Completely different universe.
De Libero emphasizes that "buyers are prioritizing platforms that integrate seamlessly with their ecosystem and don't require large teams of technical experts to implement or operate." This highlights the disconnect between the advanced capabilities vendors promote and the technical resources organizations have available.
3. Organizational Readiness
Perhaps the most overlooked challenge is organizational readiness. Adopting a composable architecture isn't just a technological change; it's a fundamental shift in how teams collaborate and the organization approaches digital transformation.
"Skills and budgets are lagging behind features and technology. That's just a reality," notes De Libero. This gap in readiness creates friction when implementing even the most promising architectural approaches.
Bridging the Gap
How can organizations reconcile the strategic vision of composable architecture with practical implementation realities? De Libero suggests several approaches:
Align on Business Outcomes
Instead of focusing solely on technological capabilities, all stakeholders should align on business outcomes. "ROI that gets everybody excited. Practical solutions that help ground the vision," advises De Libero.
Organizations can create a unified approach that satisfies analysts, buyers, and vendors by establishing shared goals around business value, marketing efficacy, customer experience impact, and implementation feasibility.
Start Small and Scale Gradually
Organizations should consider an incremental approach rather than attempting a wholesale shift to composable architecture. Begin with specific components that address immediate business needs and demonstrate clear value.
This approach allows teams to gradually build expertise and develop integration patterns within their specific context. It also provides opportunities to demonstrate ROI–crucial for securing continued investment.
Invest in Technical Capabilities
Closing the skills gap is essential for successful implementation. This might involve training existing team members, hiring specialists, or partnering with experienced implementation providers.
Buyers are increasingly drawn to platforms with intuitive, low-code tools that enable business users to build and manage content without developer intervention. These tools can help bridge the technical gap while more comprehensive capabilities are developed.
The Vendor Responsibility
Vendors have a critical role to play in addressing the implementation gap. De Libero points out vendors are "racing ahead with new tech, but not always what users can use."
Forward-thinking vendors are adapting their strategies in several ways:
- Developing industry-specific offerings that address the unique needs of sectors like healthcare, finance, and retail
- Investing in partner ecosystems to provide implementation support
- Creating low-code/no-code interfaces that empower business users
- Offering more transparent pricing models that clarify the total cost of ownership
The Future of Composable Architecture
Despite the implementation challenges, composable architecture remains a compelling vision for the future of digital experiences. As organizations build capabilities and vendors develop more accessible solutions, the gap between vision and implementation will narrow.
"If you get this right, the 2025 DXP ecosystem isn't a mess—it's a powerhouse," concludes De Libero. "Business wins, customers win, martech delivers."
The key lies in balancing innovation with practicality, focusing on outcomes rather than technologies, and building the capabilities needed to thrive in a composable future.
Threading the Needle
Marketing and IT leaders are caught between the alluring promise of composable architecture and the stubborn reality of implementation hurdles. What matters most isn't following industry hype but making smart, incremental moves that deliver tangible value. Organizations that recognize this tension—and work within it rather than pretend it doesn't exist—stand the best chance of success.
"Innovation that fits today's reality, not the hype of tomorrow" isn't just a catchy line from De Libero; it's practical wisdom for technology leaders drowning in vendor promises and analyst predictions.
Ultimately, there's no binary choice between old-school monoliths and cutting-edge composability. The smartest path threads the needle—embracing modularity where it makes sense, maintaining integrated systems where they work, and always keeping one eye on your team's capabilities rather than where the market claims you should be. Companies that master this balancing act will quietly outpace competitors who are still chasing architectural purity at the expense of business results.
