Microservices have emerged as a pivotal force in the realm of software development, particularly influencing the digital transformation of lending businesses. This revolutionary approach entails the creation of distinct, autonomous services for various business functions, allowing them to interconnect as needed. By orchestrating a collection of these independent services, a loosely coupled architecture is formed, equipping lenders with unparalleled adaptability.
Microservices Defined:
- Microservices constitute a variation of the service-oriented architecture (SOA), organizing applications as an assembly of loosely connected services.
- Each microservice operates discretely, dedicated to a specific business function, encapsulating its data and enabling autonomous deployment and scaling.
- These services can be built using diverse technologies, chosen based on purpose or developer preference, enhancing versatility.
Granular LOS Functionality:
- Key lending processes, like underwriting, closing, income, and asset services, can be decomposed into microservices owned and operated by distinct teams.
- Independent updates can be performed on services like income and asset, bolstering maintainability and testability concurrently.
Efficient Communication:
- Microservices communicate through APIs and API gateways, streamlining data flow and reducing development time and coding errors.
- This optimized communication structure minimizes bandwidth requirements and infrastructure costs.
Advantages of Microservices in Lending:
- Components are replaceable, with reduced impact on other elements, enhancing agility and resilience.
- Upgrades occur swiftly with minimal downtime, amplifying efficiency and diminishing maintenance costs.
- Customization for organizational needs becomes easier, ensuring swift implementation of regulatory changes, greater scalability, and productivity.
- Open platforms can be leveraged effectively.
- Reusability extends across various business lines, from mortgages to credit cards, loans, and insurance.
- Microservices enable rapid testing due to their small scale and facilitate independent release cadences.
- Independent deployment and scaling via containers enhance operational flexibility.
Embracing Microservices in Lending:
- Major global banks are adopting microservices in areas like open banking, employment and income verification, and payments.
- Lessons from these pioneers offer valuable insights for the mortgage industry, enabling the application of cross-industry best practices.
