Today’s public and private clouds are built to run cloud-native applications architected for shared-nothing, scale-out, commodity infrastructure that can fail often. They give enterprises easy access to a number of geo-distributed datacenters for increased availability and fault-tolerance but also require application developers to think about infrastructure agility, data locality and cross-datacenter replication. Mission-critical applications with their strict need for data correctness and availability have thus become significantly challenging to run on modern cloud infrastructure.

Current generation of operational databases were never built to solve the above challenges. Strongly consistent scale-out SQL databases, that started out as sharding and clustering layers on top of monolithic SQL databases (such as MySQL and Postgres), provide the much needed data correctness guarantees but are only fit for private datacenters interconnected with highly reliable custom networks. Eventually consistent NoSQL databases (such as Cassandra and MongoDB) provide higher availability but do not provide strong guarantees around data consistency or zero data loss during failures.

In this session, we will review the architecture and design of YugaByte DB, a new open source, cloud-native database purpose-built for mission-critical applications. YugaByte DB provides a strongly consistent core similar to SQL databases while also enabling multi-datacenter high availability similar to NoSQL databases. Stateful applications can now easily scale up and scale down in both public and private cloud platforms without incurring operational complexity or losing data during failures.

Speaker: Karthik Ranganathan

Co-Founder & CTO @YugaByte

"Karthik received his BS and MS in CS from IIT-M and UT Austin. Karthik was instrumental in driving adoption of scale-out databases like Cassandra and HBase at Facebook across several mission-critical verticals, and has worked with a number of companies trying to adopt these technologies as a part of the open source community. He is an open source HBase committer, and also an early contributor to Cassandra at Facebook, before it was open sourced by Facebook. Karthik started working on Cassandra 10 years ago - before it was called Cassandra and well before the world knew of it. He then went on to work on the guts of HBase, adding features that would make it an enterprise-grade NoSQL data platform powering 8-10 very large use cases within Facebook with many petabytes of data in it. He worked again on Apache Cassandra at Nutanix where it had been heavily modified to support strong consistency and use as a highly reliable metadata store. He is now the Co-Founder and CTO at YugaByte, building an open source cloud-native database for mission-critical applications.
