Class Distributed Computing

Course focused on building distributed applications, which addresses the main theoretical and practical aspects necessary for building these applications. The characteristics of distributed systems and the challenges in their construction are analyzed so that they function with good performance, reliability and security. The practical component involves building a client-server system with multiple servers and communication using SOAP and REST Web Services and Java RMI.
