At Audion, we needed a way to send targeted Slack messages from our microservices for custom alerts, monitoring, and notifications. We aimed for a solution that was reliable, scalable, cost-efficient, and easy to integrate.
We decided to leverage Google Cloud Platform, using Pub/Sub as a message broker and Cloud Functions triggered by Pub/Sub events to interact with the Slack API. This serverless approach allowed for loose coupling and minimal maintenance.
