The modernization of financial IT

Opensense offers to financial organizations solutions meeting their modernization needs through a comprehensive offering: deploying a modern, open and flexible infrastructure, opening up your legacy systems, and building modular business tools with native integration of regulations.

Deploying a modern, flexible and open infrastructure

Opensense deploys modern infrastructures which facilitate change by dividing your systems into simple, independent functions.

The autonomy of a function involves one process, one source code repository and one life cycle. This autonomy will enable you to:

  •  “scale” technical teams efficiently: deployments are independent, which greatly enhances work parallelisation
  • simplify comprehension of your systems, thereby increasing sharing potential: isolating a business service around a single function provides radical simplification

The main issue to a successful autonomy remains communication between functions / microservices, which restricts independence. However, Opensense offers the expertise and technologies to inner such coupling:

  • Reducing the need to understand your environment: event sourcing, asynchronous flows
  • Shifting data querying: “inside out” / “unbundled” databases
  • Reducing changes of contract: API first

Opensense deploys robust, efficient infrastructures which are auditable and adapted to big or fast data. The services developed are automatically:

  • replicated according to load
  • restarted in the event of failure
  • fully or partially replayed in the event of errors
  • auditable by means of a standardised event communication system

Opening up legacy systems

Opening up legacy systems requires expertise in a wide range of skills, in order to simultaneously intervene on:

  • operating systems: zOS (IBM), OpenVMS (HP), etc.
  • applications : COBOL, etc.
  • databases: Db2 (IBM), Rdb (Oracle), etc.

Opensense now offers this expertise both in-house and through the establishment of firm partnerships with renowned legacy system experts.

Several types of intervention may be undertaken to open up a legacy system, including the following examples:

  • Simplifying access through the development of modern interfaces (e.g. REST) in order, for example, to query in SQL and list/download files
  • Facilitating orchestration and initiation of new functionalities by retrieving changes to databases in the form of events (i.e. CDC to broker)
  • Receiving better alerts for certain operations by exporting business metrics to modern alerting systems

Building modular tools with native integration of regulations

Financial organizations are always keen to make savings by simplifying and automating business processes.

Opensense builds financial and banking tools which are simple, automatic yet modular, and are able to adapt to the  modernization of entire systems.

Furthermore, the tools developed by Opensense feature native integration of complete traceability for all actions performed by the tool during a transaction. This very fine granularity makes it possible to quickly align with any new regulations at no additional cost. Our microservices communicate by events and their actions are auditable without any additional effort.
