Modernization to Cloud

Design and development of the Account Authorizer micro-service

 

General problems

The role of the Authorizer is to receive, authorize and process all debit, credit, reversal and simulation operations from all the bank's channels, therefore being one of the main functions of the entire bank. It was for many decades exclusive to mainframe-implemented code. With the modernization to the cloud platform, this function needed to be redesigned to be able to provide a throughput of thousands of transactions per second.
