Abstract

The paper proposes a cyber laboratory in the form of a hybrid cloud, where the actual laboratory and the remote laboratory are combined. At the existing physical experiment laboratory, the limitation of the number of experimental devices for FPGA hardware design course resulted in platform usage congestions and extended laboratory hours. Migration to the cloud should be the natural solution. However, existing devices such as FPGA evaluation devices and Logic analyzers became obstacles to migrate to public clouds. The proposed system combines an On-Premise private cloud organized by laboratory platforms to perform device dependent services, and a public cloud where remaining design, development and evaluation stages, are carried out in the form of a PaaS (Platform as a Service). The design and experiment tasks should be modified accordingly to accommodate CAD tools in the set of the Web Services. Existing faculty database server and educational support system combine the private cloud, the public cloud and the faculty servers, in a seamless way. Students can migrate to and from laboratories at any design stages. As the device dependent tasks have been implemented in the Web Services, efficient sharing of platforms can be achieved in space and time sharing fashions. The public cloud ensures a scalable increase and decrease in server machines according to the student usages and seasonal load changes. The laboratory managing software takes care of the allocation and migration of student Virtual-Machines between the On-Premise private cloud and the public cloud. It can also accommodate the BYOD (Bring Your Own Device) style student usage, by preparing three different access methods: student side BYOD applications, the Web services and remote desktop connections.
