"Non-functional benefits of scaling your web tier using Data Grids" by Mak Addy

Many developers and architects avoid application clustering of web sessions as they perceive it to be "heavy weight", preferring their customers to reauthenticate and restart transactions than clustering their web sessions. In this session we will explore how to change this archaic practice by using In-memory Data Grids to give you highly scalable, highly available web session state with the benefits of multi-application sessions sharing, as well as operational improvements without annoying your users.
 
Mark Addy currently works as a Senior Consultant at C2B2 a UK Java consultancy which specializes in building fast, scalable and reliable systems. He has extensive experience delivering development, troubleshooting, problem analysis and performance tuning services to clients spanning a wide range of industries. Mark has spoken at JUDCon Boston, London JBoss User Group and GeeCon 2013.

"Dr. Low Latency or: How I Learned to Stop Worrying about Pauses and Love the Memory" by Jaromir Hamala

Cheap RAM means we can use more memory than an average disk size was not that long time ago. It's very tempting to increase size of our JVM heap and store more data in-memory. As always, there is a trade-off: Large heaps lead to higher latencies due to Garbage Collector overhead. This session will show different strategies for accessing off-heap memory and using the advantage of large RAM without paying the performance penalty.
