Implementation of a Brokering Service

[andrasmarkus]

Building on the current functionality of the simulator, the goal is to model behaviour similar to that of a cloud broker service. The proposed functionalities are as follows:

Broker: The broker will maintain an information base of virtual machine instances provided by multiple cloud service providers, including details such as CPU cores, memory, and pricing. It will also monitor the load of these cloud providers.

Application Request: This will be a description that defines the number of CPU cores and memory required by the owner, the desired storage size, and the available budget for the request.

Brokering Algorithm: The purpose of the algorithm is to utilise the information collected by the broker and the mapping of the application request to the cloud resources. Additionally, the task may include implementing and comparing multiple algorithms that weigh decisions differently, for example, based on the current load of the architecture.
