Roadmap PoC

• Decide between mono/polyrepo and a basic project layout🤺
• Implement basic Golang service and containerize 🐳
• Select API Gateway 🐙
• Setup and containerize UI (react)
• Select messaging technology (thinking Kafka)
• Service discovery (is this needed)
• Sentiment Analysis thinking AWS Comprehend or resurrecting old python project

API Gateway

Many choices out there but have gone with KrakenD

Besides sharing the same name as my favorite crypto exchange and a fairly impactful rum KrakenD is built using Go, is highly performant and its sweet spot seems to be backend service aggregation which is what I am looking for, this combined with near zero complexity and a declarative configuration makes it an easy choice.

Summary -

• On the-fly API creation using upstream services, with cross-cutting concerns (api gateway).
• Not a proxy, although it can be used as one.
• No node coordination
• No synchronization needed
• Zero complexity (docker container with a configuration file)
• No challenges for Multi-region
• Declarative configuration
• Immutable infrastructure
• Runs on micro and small machines in production without issues.
• Customizations in Go, Lua, CEL, and Martian DSL
