<p>Bot: Creating new article from JSON</p> <p><b>New page</b></p><div>💻 &#039;&#039;&#039;Microservices architecture&#039;&#039;&#039; is a software design approach in which an insurance platform is built as a collection of small, independently deployable services — each responsible for a discrete function such as [[Definition:Policy administration system | policy administration]], [[Definition:Claims management | claims processing]], [[Definition:Rating engine | rating]], or [[Definition:Billing | billing]]. Rather than packaging all capabilities into a single monolithic application, microservices break the system into loosely coupled components that communicate through lightweight APIs. This pattern has become a defining feature of modern [[Definition:Insurtech | insurtech]] platforms and is increasingly adopted by established [[Definition:Insurance carrier | carriers]] seeking to modernize legacy technology stacks.<br /> <br /> ⚙️ Each microservice operates as its own unit with its own data store and deployment lifecycle, meaning a development team can update the [[Definition:Underwriting | underwriting]] engine without touching the [[Definition:Document management | document management]] service or the [[Definition:Customer portal | customer portal]]. In practice, an insurer might run separate microservices for [[Definition:Quote | quote]] generation, [[Definition:Endorsement | endorsement]] processing, [[Definition:Premium | premium]] calculation, and [[Definition:Regulatory compliance | regulatory reporting]], orchestrating them through an [[Definition:Application programming interface (API) | API]] gateway. If one service experiences a spike in demand — say, [[Definition:First notice of loss (FNOL) | FNOL]] intake after a storm — it can be scaled independently without provisioning additional resources for the entire platform. Container orchestration tools like Kubernetes typically manage this scaling, while event-driven messaging ensures services stay synchronized.<br /> <br /> 🔑 For insurers operating in a fast-changing competitive landscape, the architectural flexibility of microservices translates directly into business agility. A carrier can launch a new [[Definition:Product line | product line]] or integrate a third-party [[Definition:Data analytics | data analytics]] provider without re-engineering its core system — a process that in monolithic environments often takes months. The approach also reduces vendor lock-in, allowing organizations to swap out individual components as better solutions emerge. However, the complexity of managing dozens or hundreds of services demands strong [[Definition:Data governance | governance]], observability tooling, and disciplined API versioning, which is why many insurers adopt microservices incrementally rather than through a wholesale rebuild.<br /> <br /> &#039;&#039;&#039;Related concepts&#039;&#039;&#039;<br /> {{Div col|colwidth=20em}}<br /> * [[Definition:Application programming interface (API)]]<br /> * [[Definition:Policy administration system]]<br /> * [[Definition:Cloud computing]]<br /> * [[Definition:Legacy system modernization]]<br /> * [[Definition:Insurtech]]<br /> * [[Definition:Service-oriented architecture (SOA)]]<br /> {{Div col end}}</div>
