We are reimagining Postgres as a native cloud service, not just running it in the cloud. 3. Architected as a Cloud DBMS Bring capabilities of leading commercial RDBMS to Postgres in a cloud-native architecture. E.g. DR & replication, perf & observability, security, etc. 2. Enterprise Grade by Default YugabyteDB: Building on Top of Postgres Innovations Fully PostgreSQL compatible API for workload portability. Leverage resilience, dynamic scalability, and multi-site distribution in the DB to make your app cloud native. 1. Distributed Postgres

How do you architect for zero downtime with YugabyteDB? ● Assume nodes and zones will fail often ● Users should have zero impact ● RPO=0, RTO~3s with sync replication ● Replication lag typically <500 ms with async Async replication between two clusters in different regions Region 2 Region 3 Region 1 Sync replication across regions within a cluster

Business objective: Get Paramount+ closer to their end users With the anticipated expansion through globalization and release of new services and content, Paramount+ needed a database platform that could perform and scale to support peak demands to provide the best user experience Multi-Region/cloud deployment • High availability and resilience • Performance at peak scale Compliance with local laws • Conform to GDPR regulations • Conform to local security laws

© 2024 – All Rights Reserved YugabyteDB and Paramount+: Global authentication and user profiles Past challenges Paramount+ original single-region architecture with MySQL ● Slow read performance due to MySQL being limited to a single region ● No horizontal scalability due to limited primary and follower architecture (single 64- core node handled all writes) ● Costly downtimes due to no region-level fault tolerance in single-region architecture ● Potential data loss due to high replication lag and potential primary node failure Use case: Powers user log in, authorizes content viewing, and manages profile information (watchlist, account details, preferences, etc); YugabyteDB is the system of record for global authentication and all user profiles to view content
