Large enterprises have increased in complexity over time, often resulting in inflexible and fragile systems. Legacy applications further complicate the situation, making system interconnectivity across your company difficult. To retain business agility in a world of mobile, API, and SaaS, enterprise integration is crucial. Enterprise integration boosts productivity and enables better decision-making by offering accurate information when you need it.
Role of microservices in integration
Enterprises are resorting to a more modular, loosely-coupled approach to building enterprise IT because monolithic architectures are complex and do not allow for agile changes in functionality. Breaking down an application into small and independent components that can perform discrete services is at the core of microservice architecture. For example, instead of implementing a complete mapping module in a travel application, microservice could focus on only a ZIP-code lookup. This allows for shorter release cycle times, a need of the hour in today’s business context.
Microservice architecture, built on the principles of SOA from integration to implementation, gives flexibility on how services can be realized.
Broadly, microservices can be classified into Journey services, Business services, and Data services.
Journey Services provide or cater to customer journeys like recommendation services in an e-commerce portal, like search and browse services.
Business Services are those that execute business functionality like placing an order or withdrawal operations in a banking application.
Data Services help retrieve enterprise data in an easy-to-consume format like JSON, or XML. Example: Checking account balance in a banking application.
