Query: Poster: A Real-World Distributed Infrastructure for Processing Financial
  Data at Scale   Financial markets are event- and data-driven to an extremely high degree. For
making decisions and triggering actions stakeholders require notifications
about significant events and reliable background information that meet their
individual requirements in terms of timeliness, accuracy, and completeness. As
one of Europe's leading providers of financial data and regulatory solutions
vwd processes an average of 18 billion event notifications from 500+ data
sources for 30 million symbols per day. Our large-scale distributed event-based
systems handle daily peak rates of 1+ million event notifications per second
and additional load generated by singular pivotal events with global impact. In
this poster we give practical insights into our IT systems. We outline the
infrastructure we operate and the event-driven architecture we apply at vwd. In
particular we showcase the (geo)distributed publish/subscribe broker network we
operate across locations and countries to provide market data to our customers
with varying quality of information (QoI) properties.
