From Flipkart to the Community: Open-Sourcing Varadhi's Managed Restbus

Varadhi is Flipkart's managed RESTBus, featuring a message bus implementation with a REST interface and a message broker underneath. At its core it enables reliable, asynchronous and optionally ordered service to service communication patterns using REST interface. 

From a minimalistic footprint a decade ago, currently it has scaled to more than 350 brokers, 3000 topics and 10000 subscriptions in multiple data centers. At its peak, during Flipkart’s flagship BBD event, more than a billion messages passed through the Varadhi platform in a single day with use cases spanning through entire Flipkart’s funnel. 

In this session we aim to share below:

1. Why use a RESTBus over message brokers for app integration use cases.
2. REST Bus patterns Pub/Sub, Request/Response.
3. A decade of journey in developing and using the RESTBus.
4. Sneak peak in core features.
5. Learnings and how they are being addressed in the open source version of Varadhi.
6. Open sourcing of Varadhi and how one can contribute.
