Data Grids
TxVia's platform data is managed by an advanced in-memory partitioned data grid that can economically scale online processing to tens of thousands of transactions per second across terabytes of account-on-file data. This grid approach provides predictability in the sizing of processing capacity to meet the needs of network-based payment systems, the ability to handle peaks and a clear path to cost-effectively increase capacity over time. The grid supports wide-area networks, so that compute resource may be distributed geographically. Additionally, TxVia's PaaS delivery model and security innovations allow payment platforms to exist within public elastic compute clouds, providing automatic scaling up and down of infrastructure to support varying loads. In some cases, without the ability to support elastic provisioning of infrastructure, the concept of a network-based payment system may not be economically viable. TxVia supports active-active configuration processing for all its platforms, both within the TxVia infrastructure and the client's infrastructure and all data, without exception, is stored encrypted with AES-256 at all times, with keys optionally protected using Hardware Security Modules (HSMs).
