Web Service Architecture and API Integration Design

Building robust web applications requires a solid architectural foundation and seamless communication between services. This course guides you through designing scalable web service architectures and modern integration pipelines from the ground up. You will learn how to translate business needs into technical specifications and structure reliable back-end systems. What you will learn: Understand foundational architectural terminology, concepts, and system design patterns; Gather and define functional and non-functional requirements for web services; Evaluate and select database models, caching strategies, and scaling mechanisms; Design resilient inter-service communications using REST, gRPC, WebSockets, and Webhooks; Implement event-driven architectures using message brokers like Kafka; Document APIs clearly using OpenAPI and Swagger specifications while applying basic observability patterns. The curriculum begins with core terminology and foundational concepts before moving into practical architecture design and infrastructure decisions. This course is created for beginner developers, systems analysts, and aspiring software architects with no prior experience in system design.
