A relational database has long been the go-to choice for PHP application developers, but as applications grow the data doesn’t always fit the relational model. Perfect normalised data structures have their place, but in the world of rapid delivery, cloud computing & microservices developers need more in their toolbox. This talk looks at when you might want to try a different data store, and how you’d look to build out or migrate to a new service. We’ll look at queues, key-value, document stores primarily (with some specific examples in Amazon DynamoDB, MongoDB and Redis). We’ll also look at some emerging database types such as graphs and ledgers.
