Enity
The Enity is a class from discrete event simulation library Akatosh. All PyCloudSim simulated entities are built based on it.
An entity could be considered as an actor/NPC which lives within the simulated envrionment. The NPC comes to life with create() function and dies with terminate() function. During its life-cycle, the NPC can engage instant event which are the event that happens once at a time point, or continous event that happens multiple times for a period of time. Any future event will be canceled upon the temination of the NPC.
Therefore, fundamentally the PyCloudSim is a series of NPC playing the roles of all things involed in cloud computing and networking, with a series of instant event and continous event.
