3. HYPER RESPONSIVE BIDDING APPLICATION ON CLOUD
Situation
Challenge
Startup ISV in trading domain wants to develop a web application for American sport
enthusiasts. This application should react instantly to the momentums of the live
game and should scale up/down based on events and user load.
Harbinger Solution
Harbinger developed a hyper responsive application on cloud. Implemented HTTP Push
notification using Node.js based event loop model and Socket.IO. Push notifications
were used to broadcast bid updates to traders in real-time for multiple simultaneous
live sport events. In order to optimize performance further database roundtrips were
avoided by using Redis in-memory queues as a data store for live events. Combination
of Node.js , Redis and Push mechanism ensured quick response time.
Designed and implemented a generic data store using Redis and MongoDB. Using
Redis, individual runtime queues per live event ensured transaction management when
data was in memory. Once event is closed, data is persisted from Redis queues to
MongoDB data store for later usage like reporting, dashboards etc. After data is
available in MongoDB, transaction management support from MongoDB is utilized for
consistency.
Application is hosted in Amazon cloud, Amazon EC2 APIs used so application can
automatically scale up or down depending on its need i.e. as number of users and
concurrent events grows
Benefits
Develop an application which synchronizes
thousands of users in real-time and notifies
the traders about each highest bid placed,
within fraction of seconds
Need to handle transactions for thousands
of concurrent users in real-time
Application usage spikes significantly with
popular events

Ensured a real-time game experience, as good as users are in the stadium and
witnessing the game live. This resulted into increased user base, enhanced application
usage and revenue growth.
Support for bidding across multiple and concurrent live game events, facilitated traders
to participate and enjoy several sport events simultaneously
BOTTOM LINE
A real-time, highly scalable and hyper
responsive biding application on cloud for
sports enthusiast.
Highly scalable application which enabled seamless user experience, on-demand and
optimal use of computing resources and reduced infrastructure cost
