The world at large seems sold on microservices as a way to build large, quality systems at the speed needed to compete in today's market. However, microservices are not without their downsides, one of which is the difficulty of reasoning about and optimising the performance of microservices working in tandem. In this session, attendees will learn the key concepts needed to measure the performance of their services, identify potential bottlenecks and take corrective action to ensure services perform as needed.
Before we can reason about the performance of connected services, we must understand how to reason about services in isolation. The first half of the session is dedicated to discussing how to measure service performance correctly, what metrics matter and how to compare the performance of a service over time.
In the second half of the session, we take our single-service knowledge and expand it out to reason about a set of services working together to provide some aggregate function. We'll see how the performance of each service affects the performance of the whole, and learn how to identify where to focus our optimisation efforts.

As CEO at Skipjaq, Rob Harrop leads a team working on the cutting edge of machine-driven performance optimisation. When he’s not thinking about how best to tune the myriad workloads encountered by Skipjaq customers, he’s thinking hard about how to pass the optimisation burden on to machines that learn. Rob is well known as a co-founder of SpringSource, the software company behind the wildly-successful Spring Framework. At SpringSource he was a core contributor to the Spring Framework and led the team that built dm Server (now Eclipse Virgo). Prior to SpringSource, Rob was (at the age of 19) co-founder and CTO at Cake Solutions, a boutique consultancy in Manchester, UK. A respected author, speaker and teacher, Rob writes and talks frequently about large-scale systems, cloud architecture and functional programming. His published works include the highly-popular Spring Framework reference “Pro Spring”.
