In this session, we willl talk about the high level data architecture at Traveloka, Southeast Asia's leading online travel company. There are many existing solutions for big data analytics, both offered as managed services or open source. At Traveloka, we are going as serverless as possible. We will explain the challenges we have and are looking to solve, why we chose this serverless approach, pros and cons of each component that we use (Google Cloud Platform or not), and what we learned from our experience so far.
