SESSION + Live Q&A
Applied Performance Theory
How does your system perform under load? What are the bottlenecks, and how does it fail at its limits? How do you stay ahead as your system evolves and its workload grows?
Performance theory offers a rigorous and practical (-- yes!) approach to performance tuning and capacity planning. In this talk, we’ll dive into elegant results like Little’s Law and the Universal Scalability Law. We’ll explore the use of performance theory in real systems at companies like Facebook, and discuss how we can leverage it too, to prepare our systems for flux and scale.

Cluster Consensus: When Aeron Met Raft
Consensus protocols enable distributed systems to agree a common view of shared state. This common view allows a cluster to continue service while a majority of its members are available. Raft was designed to be understandable. Raft succeeded in this goal and became popular. Aeron was designed...

High Performance Actors
Typically, when looking at performance, organisations look at it in terms of resource utilisation. One way Akka actors stand out is by using resources very efficiently, while also maintaining the Reactive Principles such as resilience, i.e. the ability to react to failure in a non-catastrophic,...

Software Design for Persistent Memory Systems
Nonvolatile RAM (NVRAM) will soon be widely available. Specific software techniques will be required in order to fully realise the potential that NVRAM offers. Byte addressable persistence offers both new opportunities and new challenges. This talk will cover both naive approaches to leveraging...
