As a Database Administrator, you know just how stressful it can be to ensure your system is never down. MongoDB seeks to solve this problem by ensuring that no matter which database task you're performing, you maintain high availability. This webinar will cover how to ensure zero downtime when managing a MongoDB cluster. We'll start by covering replica sets and then dive into automated software upgrades, and describe various deployment topologies including globally deployed clusters over multiple continents. We will also describe how MongoDB helps you scale on demand without requiring downtime, by automatically redistributing data across the newly provisioned hardware. Topics covered include: High Availability through Replica Sets Automated Upgrades Backups Scaling - Sharding Common maintenance operations
