Info about Talks

 Search @

This talk will firstly give an overview of how ‘search’ works at, from sourcing the data, creating the index to serving requests. Secondly we’ll talk about why we’re experimenting with elasticsearch, why we think it can solve one of our biggest challenges and how we came to that conclusion.

The presentation will end with some thoughts about the possible migration-challenges and some of the concerns we have regarding elasticsearch.

 Continuous performance: load testing for developers with Gatling

Performance testing is traditionally a task for specialists that takes place at the very end of the software delivery life cycle. But how does this fit in with a DevOps way of working, where continuous feedback is one of the key points? It doesn't. In a world where scalability and performance are just as important as delivering new features, you need to embed performance testing in your daily development workflow: it needs to become a natural part of development. And this is where Gatling comes in: an open source load testing framework based on Scala, Akka and Netty. In this session, you will learn how to use Gatling to incorporate performance testing in development and how to provide your team with continuous feedback on your application's performance.

Subjects include an introduction to Gatling, automated recording and processing of performance tests with the Gatling Scala DSL and integration with Jenkins for automated execution, bench marking and reporting of load tests.
