        This is a project done in `PACS Lab <https://pacs.eecs.yorku.ca/>`__
        aiming to develop a performance simulator for serverless computing
        platforms. Using this simulator, we can calculate Quality of Service
        (QoS) metrics like average response time, average probability of cold
        start, average running servers (directly reflecting average cost),
        histogram of different events, distribution of number of servers
        throughout time, and many other characteristics.
        
        The developed performance model can be used to debug/improve analytical
        performance models, try new and improved management schema, or dig up a
        whole lot of properties of a common modern scale-per-request serverless
        platforms.
        
        Artifacts
        ---------
        
        -  `PyPi Package <https://pypi.org/project/pacssim/>`__
        -  `Github
           Repo <https://github.com/nimamahmoudi/serverless-performance-simulator>`__
        -  `ReadTheDocs
           Documentation <https://serverless-performance-simulator.readthedocs.io/en/latest/>`__
        -  `Examples <./examples>`__
        
        Requirements
        ------------
        
        -  Python 3.6 or above
        -  PIP
        
        Installation
        ------------
        
        Install using pip:
        
        .. code:: sh
        
           pip install pacssim
        
        Upgrading using pip:
        
        .. code:: sh
        
           pip install pacssim --upgrade
        
        For installation in development mode:
        
        .. code:: sh
        
           git clone https://github.com/nimamahmoudi/serverless-performance-simulator
           cd serverless-performance-simulator
           pip install -e .
        
        Usage
        -----
        
        A simple usage of the serverless simulator is shown in the following:
        
        .. code:: py
        
           from pacssim.ServerlessSimulator import ServerlessSimulator as Sim
        
           sim = Sim(arrival_rate=0.9, warm_service_rate=1/1.991, cold_service_rate=1/2.244,
                       expiration_threshold=600, max_time=1e6)
           sim.generate_trace(debug_print=False, progress=True)
           sim.print_trace_results()
        
        Which prints an output similar to the following:
        
        ::
        
           100%|██████████| 1000000/1000000 [00:42<00:00, 23410.45it/s]
           Cold Starts / total requests:    1213 / 898469
           Cold Start Probability:          0.0014
           Rejection / total requests:      0 / 898469
           Rejection Probability:           0.0000
           Average Instance Life Span:      6335.1337
           Average Server Count:            7.6612
           Average Running Count:           1.7879
           Average Idle Count:              5.8733
        
        Using this information, you can predict the behaviour of your system in
        production.
