Using the Event Gateway To Build Multi-Cloud Serverless Applications - JeffConf Hamburg 2018
2 likes2,811 views
The document discusses building serverless multi-cloud applications using an event gateway, which functions as a real-time data-flow engine for event-driven architectures. It covers the capabilities of the event gateway, including handling events from various cloud service providers and decoupling logic for efficient development. Additionally, it provides resources for getting started, such as a product page, GitHub repository, and example applications.

- 12. at a large scale is still hard serverless
- 13. The highly productive event router for FaaS Event Gateway
- 14. ● “Realtime data-flow engine” (L7 Proxy) ● Events (data) → Functions (serverless compute) ● API Gateway & Pub/Sub ● Run FaaS on any provider → Cross-cloud applications ● Extensible through middlewares and plugins ● Hosted version / On-Prem What is the Event Gateway?
- 16. Goals ● Express all data as events ● React to any event, with any FaaS, in any location ● Be flexible, develop fast ● Accommodate many use-cases ● Decouple logic ● Decouple teams
- 17. Express all data as events ● Receives data via HTTP and interprets it as an event ● Ingests custom event schemas ● Ingests HTTP requests as events ● Emits logs, metrics & errors as events Data
- 18. ● Any event ● Supports major FaaS providers ● Discovery ● Composition ● Communication React to any event, with any FaaS, in any location AWS Lambda Azure Functions Google Cloud Functions
- 19. Be flexible, accommodate many use-cases
- 20. Be flexible, accommodate many use-cases Pub/Sub HTTP request with special headers Request body is converted to an event
- 21. Be flexible, accommodate many use-cases Pub/Sub HTTP request with special headers Request body is converted to an event API Gateway HTTP request Request is converted to an HTTP event
- 22. Be flexible, accommodate many use-cases Pub/Sub HTTP request with special headers Request body is converted to an event API Gateway HTTP request Request is converted to an HTTP event Webhooks HTTP request from a supported integration Event Gateway knows what to do
- 23. Decouple logic, decouple teams App Functions Marketing Functions HR Functions Event ● FaaS decouples logic ● Event-driven design decouples teams
