All these micro services are controlled by a
service orchestrator built in house and
flexible enough to Stitch any business flow
using configurations. Each business flow
consist of no of command events or messages
which are served by different micro services
asynchronously. System is built for high
performance and scalability. Below are some
mechanism we implemented to handle
performance and scalability requirement.
Extensive parallelization of processing
with the competing consumers pattern,
by having multiple parallel running
(micro) service instances
Using optimistic locking, to
avoid the need for complex
distributed locking mechanisms
which was a bottleneck in
earlier monolithic architecture.
Independent scaling of
processing components,
to more flexibly manage
needed capacity
These patterns ensure that design is scalable and industry proven.
Getting Payment Processing Right
®
mobiquity core is payment processing which
has to be reliable and fault tolerant. The
®
conceptual model of the mobiquity Payments
processing is based on the ideas of the
double-entry bookkeeping. The Payments
Platform inherits three key principles from
double-entry bookkeeping:
Immutability of transactions (once created, the payment
transactions are immutable: if a transaction was created
in error, a new corrective transaction needs to be created)
Auditability of all money movements
(reliably stored and cannot be changed)
Error detection based on the zero-sum principle.
Every entry to an account requires a corresponding
and opposite entry to a different account.
