  This paper presents a scalable web-based platform called Node Scala which
allows to split and handle requests on a parallel distributed system according
to pre-defined use cases. We applied this platform to a client application that
visualizes climate data stored in a NoSQL database MongoDB. The design of Node
Scala leads to efficient usage of available computing resources in addition to
allowing the system to scale simply by adding new workers. Performance
evaluation of Node Scala demonstrated a gain of up to 74 % compared to the
state-of-the-art techniques.
