Next QConSF Conference: Applied AI for Developers QCon.ai April 2019

Speaker: Sangeeta Handa

Engineering Manager, Billing Infrastructure @Netflix

Sangeeta Handa leads Billing Infrastructure Engineering at Netflix. She is as much passionate about building scalable and resilient software as she is about leading highly engaged and impactful engineering teams. At Netflix, she has led many successful efforts including Netflix Billing Infrastructure migration from native data center to AWS, rewrite of multiple important services related to invoicing customers, gift card and promotions tracking for customers. Prior to Netflix, Sangeeta evangelized and led construction of Apple’s highly scalable financial reconciliation platform for mega-million transactions in credit card payments, iPhone & gift card transactions. Other than these she has also engineered many other systems, grounds up, that are still standing the test of time at Apple.

Talk : Building Resilience in Production Migrations

Track : Production Readiness: Building Resilient Systems

Location : Ballroom A

Day of week : Wednesday

Duration : 1:40pm - 2:30pm

How do you migrate stateful systems with confidence? Especially when downtime is not an option? Netflix Billing Infrastructure needs to be up 24/7 to support 130+ million global customers. Billing services are the source of truth for a customer’s billing state which changes as customers apply gift cards, update their Method of Payment or are just charged every month. We want this experience to be seamless and accurate anytime, day or night, so our databases are constantly in action, with no possible downtime windows.

We have succeeded in multiple major rewrites. In the first one, we migrated billions of rows from Oracle in our data center to MySQL AWS Cloud. Post that, we also rewrote Netflix Balance Service that manages gifts and promotions redeemed by customers. In the recent one, we rewrote our legacy invoice processing system and seamlessly transitioned from a MySQL solution to Cassandra. All these efforts involved different strategies that helped us achieve these with a flip of a switch and without anyone realizing that Netflix had been doing major overhauls of its Billing Infrastructure. We will share our migration stories and what helped us build resilience.

From this talk, attendees will learn:

Baseline Considerations to be thought through in migrations.
Variations and aspects of achieving zero downtime especially around state migration.
Tools and technologies that can be helpful.
