Virtualizing and Tuning Large Scale Java Platforms

A session at ArchConf

Thursday 7th April, 2016

1:30pm to 3:00pm (PST)

In this 2 part session (each part 1.5 hours), I will deep dive into the deployment architectures of large scale Java platforms. I will first set the context of the discussion around what problems exist in our industry before I proceed to lay out the concept of platform engineering and its renaissance among the developer/deployment community today. It is astonishing to see that majority of new application platforms being rolled out today miss their SLA, and 90% of these systems require 2X more hardware than what they actually need in order to run. This is an industry suffering from a double whammy, where you spend 2X on hardware and still miss your SLA; clearly something is completely broken. Now prior to delving into these new concepts, such as Microservices, Cloud Native, 3rd Platform, & 12Factor App, it is imperative to first understand the problem at hand before we apply these deployment architectural patterns. I will layout the definition of Platform Engineering as the software engineering science needed in order to understand how to precisely deploy application components onto application runtimes and how in-turn one should appropriately map the application runtimes onto the infrastructure that it needs. With this knowledge you should be able to more effectively decide when to scale-out (by how many instances), and when to scale-up.

We will conclude with covering various GC tuning techniques, and how to best build platform engineered systems; in particular, the focus will be on tuning large scale JVM deployments and various sizing techniques. While predominantly most enterprise class Java workloads can fit into a scaled-out set of JVM instances of less than 4GB JVM heap, there are workloads in the in memory database space that require fairly large JVMs. We will look at various Java platform scales, some holding a few large JVMs of 90GB heap space – servicing large multi-terabyte in memory DBs, while other platforms are of thousands of JVM instances of less than 4GB heap space on each, typical of web-app deployments. We will also take a close look at an example XYZCars.com, where a microservices approach was designed and deployed. The discussion will cover how to more correctly deploy microservices, without causing fragmentation of scale, and hence without impeding performance. In this session, we take a deep dive into the issues and the optimal tuning configurations for tuning large JVMs in the range of 4GB to 360GB, using the GC tuning recipes that were gained over the past 15 years of GC tuning engagements. You should be able to walk away with the ability to commence a decent GC tuning exercise on your own, and your way to platform engineer your application runtimes to feasibly meet your SLAs.
