The best way to run the sample applications is with IDEs like IntelliJ IDEA or Eclipse. The Activities in Temporal is defined as an interface annotated with @ActivityInterface. In the case of microservice, built as a collection of small, independent, and loosely coupled services, this failure can be very hard to handle as workflow steps can span many services. Well be running the Eureka Server on port 1111. Handling transactions and maintaining data consistency among all the microservices are difficult in general. Doing this over and over 4 times can get tedious, so we do it all in bulk. Microservices architecture based applications can be developed by using Spring Boot. Feel free to checkout my code for this project here-. Microservices is an architecture pattern that is realized through a set of patterns and technologies.
