Definition ∞ Microservices represent an architectural approach where an application is built as a collection of small, independent services. Each service runs its own process and communicates with others through well-defined, lightweight mechanisms, often HTTP APIs. This design allows for independent development, deployment, and scaling of individual components, enhancing agility and resilience. Unlike monolithic applications, microservices promote modularity, enabling specific functionalities to be updated or replaced without affecting the entire system.
Context ∞ The adoption of microservices architecture is prevalent in modern software development, including within the digital asset sector, for building scalable and flexible platforms. Financial technology companies leverage microservices to manage distinct functionalities like trading engines, custody solutions, and data analytics. This approach facilitates rapid iteration and adaptation to changing market demands and regulatory requirements. Discussions often concern the complexities of distributed systems management and ensuring consistent data across independent services.
