But We're Already Open Source! Why Would I Want To Bring My Code To Apache? - Nick Burch, Quanticate
So, your business has already opened sourced some of it's code? Great! But now, someone's asking you about giving it to these Apache people? What's up with that, and why isn't just being open source enough?

In this talk, we'll look at several real world examples of where companies have chosen to contribute their existing open source code to the Apache Software Foundation. We'll see the advantages they got from it, the problems they faced along the way, why they did it, and how it helped their business. We'll also look briefly at where it may not be the right fit.

Wondering about how to take your business's open source involvement to the next level, and if contributing to projects at the Apache Software Foundation will deliver RoI, then this is the talk for you!

Pulsar: Realtime Analytics at Scale Leveraging Kafka, Hadoop and Kylin - Tony Ng, eBay
Enterprises are Increasingly demanding realtime analytics and insights to power use cases like personalization, monitoring and marketing. We will present Pulsar, a realtime streaming system used at eBay which can scale to millions of events per second with high availability and SQL-like language support, enabling realtime data enrichment, filtering and multi-dimensional metrics aggregation.

We will discuss how Pulsar integrates with a number of open source Apache technologies like Kafka, Hadoop and Kylin (Apache incubator) to achieve the high scalability, availability and flexibility. We use Kafka to replay unprocessed events to avoid data loss and to stream realtime events into Hadoop enabling reconciliation of data between realtime and batch. We use Kylin to provide multi-dimensional OLAP capabilities.

Apache Olingo - From Incubation to a Real Olingo (Apache TLP) - Michael Bolz
The Apache Olingo project actual contains Java and JavaScript libraries which provided development support for the realization of an OData service as a server in addition to support for consuming an OData service as client.
Before the Apache Olingo project started there was an earlier Open Source project from which we learnt that it’s best to start from scratch and thereby avoid failures from the past. By starting afresh, we could do everything better than before.This is how the Apache Olingo was born.
In his presentation, Michael will explain…
* Why it was decided to start a new Open Source project (to learn from past mistakes)
* Why Apache was chosen
* The Apache journey - from Incubation to a Top-Level-Project)
* The future of Olingo (not the attic)

Michael will explain the pros and cons of an open source project and talk about his own experiences and lessons learned as be
