Utilizing the advantages the cloud offers to their fullest potential is not a simple task. Often users struggle with the technological aspects, waste resources or fall behind by not taking the risk to use such services due to a lack of standards for performance descriptions, the steep learning curve to get familiar with the cloud, and the abundance of available services.This work proposes the development of a cloud broker with...

The adoption of IoT devices has expanded due to their benefits, and the Web of Things (WoT) standard has further simplified access. However, enabling end users - especially non-technical ones - to compose WoT environments remains complex due to challenges in expertise, effort, and time. This thesis systematically analyzes the situation, identifying three key barriers: insufficient interoperability, usability, and usefulness. A set of requirements for end-user Things composition is derived and used to assess existing WoT research, revealing shortcomings in supporting heterogeneous Things...
