There are so many database products to choose from nowadays. It can help to understand the overall landscape and how the available alternatives can be grouped into five (or six) categories: key-value, wide column, document, graph, search, and Hadoop/Spark. The goal of this presentation is to briefly explain strengths and weaknesses of each category, so that participants are able to choose the right tool for the job in each circumstance.

MySQL high-availability has usually been an exercise in tradeoffs: You can choose asynchronous replication and risk losing committed transactions on a failure. You can choose disk based (DRBD, SAN) replication for better durability but longer failover downtime. Galera replication has finally raised the bar for MySQL HA: You will learn how Galera brings synchronous, true multi-master and high performance (parallel slaves) replication to MySQL. You will learn how to start your first Galera cluster, and how to plan your architecture for maximum resiliency.
