Case studies examples

Lift & shift

A customer used Reply ‘s Managed Service offering to migrate their legacy HPC cluster on-premise to the AWS Cloud (Windows Environment) implementing a Landing Zone including all Security and Compliance policies. This resulted in 30% cost savings achieved without any code changes, improvement in time to market and agility .


A global banking and financial services company needed to address their Risk Data Aggregation and reporting capability for compliance. Reply Implemented a Hadoop Data Lake with Spark in Scala ingesting tens of TB of data from external sources and a risk evaluation engine defining rules and logics for functional requirements during the ingestion. The solution enabled a faster risk evaluation combined with the reduced storage and computation costs.


A major bank wanted to optimise their collateral risk exposure process, collateral payments. Reply delivered a Quadratic Unconstrained Binary Optimization (QUBO) model using real time data techniques and leveraging Quantum inspired computing implemented on classical hardware exploiting massive parallelization . A faster, more accurate and flexible solution was delivered enabling reduced costs of collateral payments and agility in addressing the collateral exposure in the future.
