Traditional databases have been designed for system of record and analytics. Modern enterprises have orders of magnitude more interactions than transactions. Couchbase Server is a rethinking of the database for interactions and engagements called, Systems of Engagement. Memory today is much cheaper than disks were when traditional databases were designed back in the 1970's, and networks are much faster and much more reliable than ever before. Application agility is also an extremely important requirement. Today's Couchbase Server is a memory- and network-centric, shared-nothing, auto-partitioned, and distributed NoSQL database system that offers both key-based and secondary index-based data access paths as well as API- and query-based data access capabilities. This lightning talk gives you an overview of requirements posed by next-generation database applications and approach to implementation including “Multi Dimensional Scaling.

System of Engagement
Contract matters. Context Matters
Systems of EngagementSystems of Record
Lower throughput
 Except on Black Friday
 And TAX DAY
Relatively higher cost is accepted
Reliability is paramount
Guarantees record of action
Implement the decisions
Speed is of the essence
Lots of questions to help decide
Large number of concurrent users
High Throughput
Low latency
Info from multiple sources and services
Low TCO
