Transformation of the IT landscape in the bank

Hello! My name is Dima Zykov , I am the architect of the Rosbank corporate architecture office.

Today I will tell you how we are changing the IT landscape in a bank using the example of updating the General Ledger - the main bank system that provides automation of accounting and storage of data on transactions in accordance with the rules and requirements of accounting of the Bank of Russia.

Background of the project

The General Ledger has 2 main functions: processing business events with their subsequent transformation into accounting events and storing events already transformed according to the accounting rules of the Bank of Russia.

Also in banking organizations there are several types of accounting - our project deals with accounting and product accounting. Product accounting also requires the implementation of its logic in the Bank's systems.

The practice of past years in the banking environment showed that the implementation of accounting algorithms can be easily combined with the implementation of the logic of product accounting in some systems, and this did not cause difficulties in the maintenance and development of such systems. However, over time, the number and variety of banking products increased, which led to the fact that the product accounting in the CORE BANKING segment became more and more. The accounting logic, strictly regulated by the regulator represented by the Bank of Russia, inevitably began to increasingly impose restrictions on changes and development in the product logic. Business requirements grew, market dynamics and factors changed.
