The past five years have been the warmest since records began. Human activity, including the IT industry, is driving worrying climate change. Data centres alone consume 3% of the world's energy, and more and more of that energy is being used by Kubernetes and workloads running on Kubernetes. Is k8s helping, or making things worse? The beauty of the cloud is that it makes it easy to run code, virtualised and scheduled for efficiency... but it doesn't provide any guarantee that what's running is useful. Even when the workload is high-value and efficient, Kube sprawl can lead to low utilisation, unsatisfactory elasticity, and high costs - but mega-mono-clusters have their own problems around isolation, security, and management. How should these competing requirements be balanced? This talk discusses some of the trade-offs and provides a roadmap to figuring out the right thing.]]>

They will answer questions such as: “Why is programming often called an art despite having its underpinnings in formal logic?” “How can I rediscover the delight I felt when I first started coding?” “What’s that rush I feel when my test passes?

As the worldwide leader of the development community of practice in the IBM Garage, Holly works with enterprises who are trying to adopt devops and shift their businesses to the cloud. Their dream is more effort higher up the value chain, more innovation, and greater adaptability. What they really want is to beat their competitors to market, with something that's better than their competitors, and then evolve it to beat any new competitors. Somehow, even after deploying Kubernetes and investing in the latest tools, things aren't better. What's getting in the way isn't the technology - setting up build pipelines and wrapping something in a docker container (usually) isn't that hard. Instead, it's the structures that have been put in place to manage risk and the relationships between teams that trip companies up. In this talk, Holly will share some stories of customers struggling to adopt devops - and the adjustments that helped them succeed. This talk explores what skills a team needs, barriers to devops, and how to know if something is ready to ship. ]]>

I’ve never seen a job I didn’t want to automate. Sometimes it’s worked out well, sometimes automation has turned a small nuisance into a big, fragile, free-time-eating monster nuisance. In this talk, I’ll explore why we automate, when to automate, the hazards of automation and the – big – rewards of automation. I’m part of the team developing IBM’s WebSphere Liberty application server. We’ve used a mix of off-the-shelf and home-rolled tools and processes to work smarter and more productively. I’ll describe what we’ve learned as WebSphere has transitioned to DevOps and continuous delivery and why I still can’t resist trying to automate all the things. These are slides from WebDeLdn presentation, May 2019.]]>

0 Six Myths and Paradoxes of Garbage Collection /HollyCummins/six-myths-and-paradoxes-of-garbage-collection hollycumminsmscdissertation-190113094618
MSc dissertation. Many myths and paradoxes surround garbage collection. The first myth is that garbage collection is only suitable for the incompetent, unskilled, or lazy. In fact garbage collection offers many architec- tural and software engineering advantages, even to the skilled developer. The second myth is that garbage collection is all about about collecting garbage. Garbage collectors also include an allocation component, which, along with their powers of object rearrangement, can make a significant difference to application performance. Thirdly, criticisms of garbage collection often focus on the pause times, and responses to these criticisms often focus exclusively on reducing pause times, in the mistaken belief that small pause times guarantee good application response times. Pause times are also often used as a metric of general application performance, and an increase in pause times is taken as an indicator of worsened performance, when in fact the opposite the opposite is often true. Paradoxically, even the total amount of time spent paused for garbage collection is not a good predictor of the impact of garbage collection on application performance. Finally, the sixth myth is that garbage collection has a disastrous performance impact. While garbage collection can hurt application performance, it can also help application performance to the point where it exceeds the performance with manual memory management.]]>
MSc dissertation. Many myths and paradoxes surround garbage collection. The first myth is that garbage collection is only suitable for the incompetent, unskilled, or lazy. In fact garbage collection offers many architec- tural and software engineering advantages, even to the skilled developer. The second myth is that garbage collection is all about about collecting garbage. Garbage collectors also include an allocation component, which, along with their powers of object rearrangement, can make a significant difference to application performance. Thirdly, criticisms of garbage collection often focus on the pause times, and responses to these criticisms often focus exclusively on reducing pause times, in the mistaken belief that small pause times guarantee good application response times. Pause times are also often used as a metric of general application performance, and an increase in pause times is taken as an indicator of worsened performance, when in fact the opposite the opposite is often true. Paradoxically, even the total amount of time spent paused for garbage collection is not a good predictor of the impact of garbage collection on application performance.

As a developer in IBM’s Cloud Garage, Holly Cummins works with customers who are trying to shift their businesses to the cloud, and to cloud native in particular. Their dream is more effort higher up the value chain, more innovation, and greater adaptability. What they really want is to beat their competitors to market, with something that’s better than their competitors, and then evolve it to beat any new competitors. What’s getting in their way isn’t the technology—wrapping something in a docker container (usually) isn’t that hard. Instead, it’s the structures that have been put in place to manage risk and the relationships between teams that trip companies up. Holly shares stories of customers struggling to get cloud native and explains how IBM applied its methodology to turn things around. You’ll learn the ideal team size, the ideal microservice size, what skills a team needs, the role of architects, how to know if something is ready to ship, and whose fault everything is (joke).]]>

This talk will cover a range of tools and techniques which can be used to track down and fix performance issues. Topics covered: Why performance really really matters What's the garbage collector doing? (And why you should care.) But why is the garbage collector doing all that, anyway?

Computers are getting small enough and cheap enough that they’re almost disposable. It’s possible to sock computers away almost anywhere, and to connect almost anything to the internet. At the same time, the Java stacks that we know and love are also getting lighter and cheaper. That combination means it’s possible to put a full spec-compliant Java EE server on ridiculously cheap hardware, and then throw it around the room without worrying too much about breaking stuff.

Presenting the world’s first cuddly, throwable application server! Computers are getting smaller and smaller and cheaper and cheaper. It’s possible to sock computers away almost anywhere, and to connect almost anything to the internet. This talk will explore the limits of embeddable hardware and present a getting-started-guide to the internet of things. What’s needed? How much does it cost? What’s the best way of making an embeddable device talk to the internet? And why would you want a throwable application server? As well as hints and tips, there will be a show-and-tell session (or “demo” if you’re discussing with your boss). Source code is at https://github.com/holly-cummins/throwable-application-server ]]>
