Better Software is Better than Worse Software

Nate Schutta, Solution Architect, Pivotal

Read more
“Digital transformation” seems like idle business fantasy. But, it’s a real strategy used by the US Air Force, Air France KLM, Liberty Mutual, DBS Bank, and others to out-innovate competition & delight people. To kick-off the day, Paul will go over how Pivotal customers like these are improving their software, how Pivotal Cloud Foundry lays the foundation for better software helps, and how you can be a part of making the world a better place with better software.

Drinking from the Stream: How to Use Messaging Platforms for Scalability & Performance

Mark Heckler, Spring Developer Advocate, Pivotal

Read more
Most mission-critical systems have distributed elements or are entirely distributed, resulting in a number of challenges: performance, scalability, reliability, resilience...the eight fallacies of distributed computing are alive and well! Messaging platforms are often used to solve these problems and increase the "ilities", but they don't come without a few complexities of their own. Come to this session to learn how to leverage open source solutions like Spring Cloud Stream, RabbitMQ, & Apache Kafka to maximize your distributed systems' capabilities while minimizing complexity. All examples will be coded *live & in real-time*!

Bootiful Reactive Testing

Mario Gray, Principal Technologist, Pivotal

Read more
Join us for an exploration of testing a reactive Spring Boot 2.x application. Test driven development gives us the confidence necessary to improve our code faster, safely. But how do you test components and services, as well as integrations across distributed systems, while maintaining fast feedback loops, and how do you do all of this within the context of reactive Java? In this talk, we'll look at how to test imperative components, reactive data flows, and mocks. We’ll examine how to take advantage of test slices, and how to test web applications. We'll look at how to ensure that API producers and consumers work well together using consumer driven contract testing without sacrificing the testing pyramid for end-to-end integration tests. And we’ll do it all within the context of reactive programming.

Pivotal Conversations

Read more
Pivotal Conversations is loosely based in the open space meeting format, meaning it is based on (un)common sense of what people do naturally in productive meetings. Pivotal Conversations is a simple meeting format where attendees will break into smaller groups and have candid conversations about topics that our speakers have composed, based on the talks they gave earlier in the day. Each 45-minute session will have a casual format where attendees can feel comfortable discussing anything they want to know more about. Although these conversations are facilitated by our speakers, attendees should really be the ones leading the conversations.

Welcome

The Reactive Revolution

Josh Long, Spring Developer Advocate, Pivotal

Read more
The reactive revolution continues. For as much as we've been talking about reactive programming in Spring for the last few years the journey has only just begun. Join Josh Long, and we'll take our reactive applications further, looking at how to build microservices for cloud platforms like PAS (Cloud Foundry) and PKS (Kubernetes). Some of the things we may cover include: - reactive NoSQL data access - reactive SQL data access with R2DBC - orchestration and reliability patterns like client-side loadbalancing, circuit breakers, and hedging - messaging and service integration with Apache Kafka or RSocket - API gateways with Spring Cloud Gateway and patterns like rate limiting - API adapters - serverless programming with Spring Cloud Function and project Riff - reactive authentication and authorization with Spring Security.

Welcome to the Reactive Revolution:RSocket and Spring Cloud Gateway

Spencer Gibb, Spring Cloud Core Co-Lead, Pivotal

Read more
As more applications are experiencing the benefits of using a reactive programming model, one of the biggest problems they experience is the mismatch between Reactive Stream back pressure and current networking protocols. The RSocket protocol enables Reactive Streams back pressure to be transmitted across a network link connecting reactive flows in multiple applications to directly affect one another in a positive way. In addition to introducing the RSocket protocol and how to use it, this talk will show integration with Spring Cloud Gateway and how it, combined with RScocket, can create a type of messaging gateway.

Four Key Performance Indicators for Every Java App

Jon Schneider, Principal Software Engineer, Pivotal

Read more
In this session, we break down the USE+Latency method (utilization, saturation, errors, and latency) and show how to most effectively measure each of them to get the most out of your monitoring tools. We'll cover a surprising way to to monitor heap saturation to get earlier warnings of future memory problems, the keys to monitoring latency for both alerting and performance tuning, and how to measure errors in a way that allows you test your apps behavior against an error budget.

How Fast is Spring?

Dave Syer, Senior Consulting Engineer, Pivotal

Read more
These days everyone wants to run more with less, and if your app consumes too many resources on PAS/PKS/PFS then it's easy to point fingers at the runtime stack. In this presentation we take stock of some of the myths and assumptions regarding the runtime costs of using Spring. The conclusion is that preconceptions about slowness, component scanning, autoconfiguration, binding, use of reflection are all completely wrong. We look at data from a large set of benchmarks, analysing the performance of Spring applications. We concentrate on JVM startup time, but data are also available regarding total resource usage, and other runtime overheads. Spring is not slow, despite many people's preconceptions, but measuring the performance can bring useful optimizations, some of which we will point out in this session. Finally, we can go deeper than that and show what kinds of apps are slower to start and why.

Thinking Architecturally

Nate Schutta, Solution Architect, Pivotal

Read more
Rich Hickey once said programmers know the benefits of everything and the trade offs of nothing...an approach that can lead a project down a path of frustrated developers and unhappy customers. As architects though, we must consider the trade offs of every new library, language, pattern or approach and quickly make decisions often with incomplete information. How should we think about the inevitable technology choices we have to make on a project? How do we balance competing agendas? How do we keep our team happy and excited without chasing every new thing that someone finds on the inner webs? As architects it is our responsibility to effectively guide our teams on the technology journey. In this talk I will outline the importance of trade offs, how we can analyze new technologies and how we can effectively capture the inevitable architectural decisions we will make. I will also explore the value of fitness functions as a way of ensuring the decisions we make are actually reflected in the code base.

Your Attention, Please: Better Observability for Distributed Systems

John Feminella, Advisory Platform Architect, Pivotal

Read more
Do you measure and monitor your applications by alerting on metrics like CPU, memory usage, and request latency? Do you get large numbers of false positives, and wish you had fewer useless messages cluttering up your inbox? What if there were a better way to monitor your distributed systems that resulted in far more signal — and much less noise? In this talk, we'll share key approaches that are effective at measuring and monitoring distributed applications and systems. Through the application of a few simple core principles and a little bit of mathematical elbow grease, firms we've tried this with have seen significant results. By the end, you'll have the tools to ensure your applications will be healthier, more observable, and a lot less work to monitor.

Living on the Edge With Spring Cloud Gateway

Cora Iberkleid, Advisory Platform Architect, Pivotal

Read more
Building upon Project Reactor, Spring WebFlux, and Spring Boot 2.0, Spring Cloud Gateway offers Spring Cloud users an impressive set of features and functionality for cloud native applications. In comparison to Zuul from Spring Cloud Netflix, Spring Cloud Gateway provides a much more flexible API for configuring the edge service of your applications. In addition, functionality such as rate limiting and websocket routing are supported out of the box. Pivotal Cloud Foundry helps integrate all of this together into a seamless experience for developers, also giving ops the ability to ensure API reliability. During this session we will introduce Spring Cloud Gateway and demonstrate its potential impact on your cloud applications.
