If you're building apps on a multi/hybrid cloud platform, you might be interested in creating a unified event notification layer. This example shows how you can achieve that with TriggerMesh for object storage services like S3 and Google Cloud Storage. Developers can subscribe to object storage notifications without becoming coupled to a single cloud platform. And it's open source 🤸‍♂️ https://www.triggermesh.com/blog/multicloud-object-storage-notifications
