The problem facing insurance technology is that businesses need to act more quickly, but the systems behind them were usually created for a far slower era. For example, an insurance company might want to launch a new product, partner with a distribution partner, enhance claims automation, introduce an AI-driven service, or change how it serves its customers.
What at first appears to be a fairly simple business initiative soon becomes a major technology project because the policy, billing, claims, customer data, and other systems are closely interconnected; this is the area in which composable architecture proves increasingly valuable. Instead of viewing the insurance platform as a single, unified system, a composable architecture divides the technology into modular capabilities that interact via clearly defined interfaces.
The aim is to modify one part of the business without having to rebuild the rest around it.
Think Building Blocks, Not One Giant Platform
Composable architecture is closely connected to ideas such as modular software design, APIs, microservices, cloud-native architecture, and independently deployable services. Microservice architecture research views it as an approach based on small services that deploy independently to enhance scalability, fault tolerance, and ease of deployment and maintenance.
What this means for an insurer is that it should regard capabilities such as quoting, payments, document generation, identity verification, customer communications, claims intake, or analytics as separate components rather than having every function permanently built into a single, comprehensive core platform. If an improved capability becomes available, the insurer will have a more direct route to integrate or replace that component without disrupting the entire technology environment.
The Importance for Insurance
Insurance products are very seldom left unchanged in the face of price adjustments, regulatory changes, the development of new distribution methods, shifting consumer expectations, and the emergence of new data sources driven by rapidly advancing AI capabilities. The technology architecture must therefore accommodate these changes.
A company modernizes in a step-by-step way rather than waiting for a large-scale replacement of its core system. Rather than posing the question “How can we replace our whole platform?”, senior management instead asks “Which capability is causing us the most problems at the moment and how can we improve that particular area?”
That makes the process of modernizing much more manageable. Modern cloud-native applications are environments composed of loosely coupled microservices and the associated infrastructure.
NIST’s DevSecOps guidance also highlights application code, infrastructure as code, policy as code, and observability as code as separate parts of a modern application environment.
APIs Become the Connective Tissue
The fact that it is composable does not mean that the components are disconnected; they still need to exchange information reliably. APIs and similar standardized interfaces serve as the link between various components.
Suppose an insurer launches a new digital claims experience. Rather than reconstructing the policy administration system to include each feature, the new experience could securely interact with the existing services that provide customer identity, policy information, payments, documents, communications, and analytics.
This approach also offers opportunities that go beyond simple internal modernization. A carefully designed API layer will make it easier to connect with agents, brokers, insurtech partners, healthcare organizations, and other participants in the insurance ecosystem.
Modularity Doesn’t Remove the Need for Security
Dividing applications into smaller services increases flexibility but also means there are more interactions to secure. NIST provides guidance for cloud-native environments that specifically covers API gateways, service identities, authentication, authorization, service meshes, and detailed application-level security policies.
Instead of taking for granted that something should be trusted simply because it is within a corporate network, the zero-trust principles concentrate on verifying access to specific resources and services.
NIST also issues specific guidance on authentication and authorization for microservice applications. This includes the use of service meshes and attribute-based access controls.
For insurers who are dealing with sensitive financial, health, identity, and policyholder information, the difference is important. Composability should increase the architecture’s flexibility, not make governance optional.
You Don’t Have to Modernize Everything at Once
The main benefit of composable thinking is that modernization becomes a series of business decisions rather than a single major technological decision. An insurance company could start with claims communications.
One person might prefer quoting, while another could concentrate on producer tools, payments, customer identity, or data analytics. Each successful element then gives rise to another reusable capability.
As time goes on, the organization shifts from a technological situation in which any change affects all other aspects to one in which each capability develops at its own rate.
The Real Goal Is Business Agility
Composable architecture is, ultimately, more concerned with optionality than with microservices, APIs, or cloud infrastructure. Insurance companies need to be able to launch new products and experiment with their customers’ experiences.
They need to connect with partners, adopt new technologies, and respond to changes in regulatory or market conditions without turning every new idea into a multi-year transformation project. The most powerful insurance platforms of the future might not be those based on a single huge technology system.
They could instead be the ones that constantly put together, improve, replace, and scale the capabilities that the business needs next. The idea behind composable architecture is that it is not about developing technology that remains unchanged, but about creating technology that can change.
The insurance industry needs to adapt quickly and remain open to new ideas. Agility Holdings Group makes investments in InsurTech, HealthTech, and other companies that are aimed at improving care and outcomes.
