EXCERPT

To support the outbreak modeling, the research body needed a mix of computations, with compute and storage flexible enough to handle different workloads. It used four main simulation engines, varying in speed and granularity of its data collection. For example, one system checks social networks every second – working at a slower pace but offering more detailed information.
