Better Software is Better than Worse Software

Michael Coté, Technical Marketer, 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. We 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*!

Event-Driven Architecture Traps

Jakub Pilimon, Principal Technologist, Pivotal

Read more
Event-driven architectures (EDA) have become more popular by the day. Organizations see a great value in them, and developers love how EDA help to grow, scale, and mirror what really happens in the business domain.However, most developers are not familiar with this kind of architecture, which can lead to common pitfalls that we’ll examine in this talk. We’ll also cover a broad set of concepts like: exactly-once delivery (is that event a thing?), GDPR, CQRS, and tackle the problem of how to version our events.

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.

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.

Efficient Web Apps with Spring Boot 2

Stéphane Nicoll, Spring Developer, Pivotal

Read more
How can we improve the efficiency of an existing web application? We could completely rewrite it, leverage more concurrency and even reactive features. But is it really worth it if we don't even measure and track the relevant metrics? In this talk, Stéphane will work on an existing Spring Boot MVC application to make it more efficient. He'll replace `RestTemplate` with `WebClient` and use Reactor operators to improve efficiency, without the concurrency pitfalls. He'll use out-of-the-box metrics, add new ones to measure, and keep an eye on capacity gains with dashboards.

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.

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.

DDD and Microservices: Like Peanut Butter and Jelly

Matt Stine, Cloud-Native Polymath and Product Owner, Pivotal

Read more
As an architectural style, microservices are here to stay. They have crossed the proverbial chasm, and now it’s time to get to work. Microservices provide us with the ability to create truly evolutionary architectures composed of cohesive and autonomous components using well known and characterized distributed systems patterns. As an architectural style, microservices are here to stay. They have crossed the proverbial chasm, and now it’s time to get to work. Microservices provide us with the ability to create truly evolutionary architectures composed of cohesive and autonomous components using well known and characterized distributed systems patterns. As we create and compose components across the hard boundary of the network, we become deeply interested in establishing the correct boundaries and has resulted in renewed interest in system design and decomposition. Fortunately, the tried and true practices of Domain-Driven Design are available to us. In this presentation, we will cover a distillation of strategic (bounded contexts, subdomains, context mapping) and tactical (aggregates, domain events) DDD techniques and demonstrate how they enable us to create effective event-driven microservices.

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.
