Replica Configuration, Scheduling, and Repeatability (Part 5 of 6)

Chris Law — Mon, 23 Mar 2026 12:19:56 +0000

In Part 5 of our Mojaloop v17 series, we focus on repeatability, ensuring performance remains stable and predictable under sustained load.
We refined deployment topology using topology-aware scheduling and resource isolation, reducing run-to-run variance and stabilising behaviour across replicas.

At a national scale, inconsistent pod placement and resource contention can quickly undermine throughput gains. These changes ensure the platform delivers consistent transaction processing, even during peak periods.

Kafka Design for Real Throughput: Partitioning, Ordering, and Concurrency (Part 4 of 6)

Chris Law — Thu, 19 Mar 2026 11:26:52 +0000

In Part 4 of our v17 series, we focus on the event backbone — how Kafka design underpins sustained, high-throughput processing across the switch.

We revisited message flow design to enable true parallel processing, aligning partitioning with business domains and tuning concurrency to maintain correctness without limiting scale.

At a national level, small inefficiencies in partitioning, ordering, or consumer stability can quickly become bottlenecks. These changes ensure the platform delivers stable, predictable performance under sustained load.

Zero-Touch Kubernetes Networking with NetBird

A recent engineering write-up on netbird.io highlighted how the INFITX Africa platform team built a zero-touch private networking for Kubernetes environments using NetBird.

As our infrastructure spans on-premise and AWS environments, we needed a way for clusters to automatically join a secure private network without manual configuration or VPN management.

Using NetBird, Kubernetes Operators, and Crossplane, networking is now fully declarative and automatically provisioned as new clusters are created.

A great example of how cloud-native tooling can simplify secure infrastructure at scale.

Removing Bottlenecks at the “Front Door” (Ingress and Gateway Path) (Part 3 of 6)

Chris Law — Tue, 10 Mar 2026 13:00:10 +0000

In Part 3 of our v17 series, we look at the ingress and gateway layer — the critical “front door” of the switch that determines how efficiently transaction traffic enters the platform.

We modernised the gateway path to unlock the full performance potential of the core services, introducing high-performance ingress components and optimising identifier handling for high-concurrency processing.

At a national scale, even small architectural constraints can become throughput bottlenecks. These changes ensure the platform can sustain high transaction volumes while maintaining security, efficiency, and global interoperability.

Batching, Caching, and Cutting “Chatty” Work (Part 2 of 6)

Chris Law — Mon, 02 Mar 2026 15:30:04 +0000

In Part 2 of our v17 series, we highlight the architectural refinements designed to unlock sustained, high-volume throughput.

We have optimized the critical path by introducing high-efficiency batching for transfer workflows and streamlining processing steps to minimize latency.

At a national scale, every millisecond counts. These structural enhancements ensure the platform remains lean and responsive as transaction volumes grow, providing a future-proof foundation for global financial inclusion

Building World-Class Mojaloop Platforms Together (Part 1 of 6)

Chris Law — Mon, 23 Feb 2026 11:56:40 +0000

Mojaloop is increasingly being relied upon as a national and regional payment infrastructure. In that role, performance is not a vanity metric; it is a trust requirement.

In Part 1 of our six-part series, we explore why sustained throughput, predictable latency, operational stability, and security-enabled performance are foundational to production-grade payment switches

Drawing on INFITX’s performance engineering work in Mojaloop v17, delivered in collaboration with the Mojaloop Foundation and adoption partners including COMESA DRPP and GISP Bantaba 2.0, we outline the core optimisations and reproducible deployment approach that strengthen real-world platform readiness

Monitoring Mojaloop

Chris Law — Tue, 23 Apr 2024 13:55:53 +0000

This post by Muzammil Bashir, unveils how to build a monitoring system to keep tabs on everything.

Here's the gist:

Leverage open-source tools (Prometheus, Grafana, Loki, Alertmanager) for a cost-effective and customizable monitoring solution.
Separate monitoring infrastructure from service integration for a clean workflow, allowing teams to focus on their areas of expertise.
Utilize Grafana dashboards specifically designed for Mojaloop, alongside pre-built dashboards for other components, for a comprehensive monitoring view.
