Reactive Summit 2017

Pravega is a next generation implementation of Log Storage which extends the existing models and adds features such as fully elastic and automatic scaling, ability to support millions of logs simultaneously, ordering and delivery guarantees in the face of node and network failures, and a fully integrated storage tiering model allowing for extensive history storage and replay without compromising performance. The unique features of Pravega make it eminently suited as a base for highly available, reliable, and fast microservices. Using the core capabilities of Pravega, microservice developers are free to focus on the specific challenges of their application, using Pravega to guarantee exactly once event processing, fast checkpointing and restart capabilities, automatic scaling in response to real time service demand changes, and high-performance event processing. This talk will explain the background of Pravega, how it was engineered to meet the challenges of event processing and logging in highly distributed environments, how automatic and elastic scaling was designed in, and how it fits into a broader microservices ecosystem which can meet the needs of a wide variety of use cases.
