Tiered resiliency application container

A computer system of providing redundancy to a transaction processing application, the system comprising:

• a resiliency processor and a non-transitory memory coupled therewith, the memory comprising computer executable instructions that, when executed by the resiliency processor, cause the resiliency processor to:
• instantiate at least three instances of a containerized process in a data processing environment, each comprising an instance of the transaction processing application configured to execute transactions received thereby, wherein each instance of the containerized process is configured to coordinate with others of the containerized processes to designate one of the instances of the containerized process as a leader instance and each of the remaining of the containerized processes as a follower instance, and wherein the leader instance is configured to:
• receive, via an electronic communications network from one or more transaction message sources, one or more transaction messages to be processed thereby;
• forward, via the electronic communications network, prior to processing the received one or more transaction messages, a copy of the one or more transaction messages to each of the follower instances;
• await an acknowledgment message from a majority thereof indicative of the follower instance having at least acknowledged that the one or more transaction messages will be processed by the leader instance;
• and
• process the one or more transaction messages only upon receipt of the acknowledgment messages from a majority of the follower instances.
