Frequently Asked Questions
The application Core is written in Java, runs on any platform where Java is availableThe configuration and behavior are written in JavScript, which is delivered to the customer
Most users run the POC on a workstation or Windows VM, but some use Mac or Linux platforms for initial acceptance
Non-stop and high load converters run on Linux servers or containers
Any cloud can be used, as long as it runs Docker Containers and an OS that supports Java. RedHat, Ubuntu, CentOS
As a microservice, each converter instance can run its own configuration to perform a separate task
Several converters can be run at the same time for ISO8583, ISO 20022, SQL/Oracle, Visa, Amex, MasterCard, clearing
Each microservice can therefore be redeployed, reconfigured and maintained separately
All connectivity, message formats, business logic, are usually delivered pre-configured, ready to run.
The customer can change all of the above, on-premise.
All configuration is easy to version-control (via git)
Super fast. Processing time is under 1 millisecond.
It can be limited by external IO, HSM, Database, of course.
Each microservice instance can be scaled separately, depending on load.
Scale with containers, service managers, or simply starting several instances
and balancing them via the neaPay Switch-Router
