One of the use cases is known as financial payments and back in 2020 I kicked off a series covering this architecture with the article Payments architecture - An introduction. The series consisted of six articles and covered architectural diagrams from logical, schematic, to detailed views of the various use cases we uncovered.
The architectures presented were based on open source cloud native technologies, such as containers, microservices, and a Kubernetes based container platform. The major omission in this series was to avoid discussing any aspect of cloud native observability.
This series will take a look at fixing that omission with an open source standards based cloud native observability platform that helps DevOps teams control the speed, scale, and complexity of a cloud native world for their financial payments architecture.
