Building Microservices in Java with Spring Boot

Course Description

The term microservices has gained significant traction over the last few years. Describing a specific style of distributed software architecture, microservices are small, independently deployable units that work together to form a complete system. Microservices live on the web, live in the cloud, and work with all manner of data (SQL, NoSQL, In-Memory). They are production-ready services driven by ever-changing demands and scale. Java developers looking to adopt microservices need to consider the practical aspects of application development. How can services be developed quickly? How can a broad range of technologies be supported? How can a consistent programming model be kept? For many companies, the answer is Spring Boot and the wider Spring ecosystem.
