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. To kick-off the day, Coté will go over how Pivotal customers like these are improving their software, how Pivotal helps, and how you can be a part of making the world a better place with better software.

Reactive Spring with Spring Boot 2.0

Mark Heckler, Developer Advocate, Pivotal

Read more
Spring Framework 5.0 is here! One of the most exciting introductions in this release is support for reactive programming, building on Pivotal's Reactor project to support message-driven, elastic, resilient and responsive services. Spring Framework 5.0 integrates an MVC-like component model adapted to support reactive processing and a new type of web endpoint, functional reactive endpoints. In this talk, we'll look at the net-new Netty-based web runtime, how existing Servlet code can run on the new world, and how to integrate it with existing Spring-stack technologies.

Cloud-Native Spring

Josh Long, Spring Developer Advocate, Pivotal

Read more
You know what nobody has ever said to me? "I wish you'd covered even more in your 45 minute 'Cloud-Native Java' talk!" And I listened! In this talk, we'll look at Spring Cloud.next to support modern microservices development, focusing on the things that really matter (or, at least, the things we've got cooking in Spring Boot 2.0 and Spring Cloud Finchley, both due before April or so):

- functional reactive REST endpoints (totally different meaning for "function" here, though)

- reactive programming with Spring Framework 5. Leverage flow control at every layer and make the most efficient use of every CPU when doing input/output. You're going to need every bit of efficiency that you can get after you've installed the patches for Spectre and Meltdown!

- Kotlin. Yes, KOTLIN: you wanted Java and I'm giving it to you.. in libraries that I'll use from Kotlin.

- messaging with Apache Kafka. Nothing funny here. It's just awesome.

- live on the edge with the new, reactive, rate-limiting, proxying, websocket-aware Spring Cloud Gateway

- ASCII art!

- reliability with circuit breakers and eventual consistency

Spring Cloud Gateway

Ryan Baxter, Software Engineer, 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. During this rapid fire 30 minute session we will introduce Spring Cloud Gateway and demonstrate its potential impact on your cloud applications.

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.

Secure Credential Management with CredHub

DaShaun Carter, Senior Platform Architect, Pivotal
Sharath Sahadevan, Senior Platform Architect, Pivotal

Read more
From the platform all the way down to the microservices which run upon it, secrets are everywhere and leaking them can be a costly experience. Understanding security best practices can be daunting. The CredHub Cloud Foundry project was designed for these reasons. This session will take a fresh look at how to enhance security within Cloud Foundry and applications through secret management by utilizing CredHub.

Using Spinnaker to Create a Development Workflow on Kubernetes

Paul Czarkowski, Principal Technologist, Pivotal

Read more
Out of the box Kubernetes is an Operations platform which is great for flexibility but creates friction for deploying simple applications. Along comes Spinnaker which allows you to easily create custom workflows for testing, building, and deploying your application on Kubernetes. Paul will give an introduction to Containers and Kubernetes and the default development/deployment workflows that it enables. He will then show you how you can use Spinnaker to simplify and streamline your workflow and help provide a full #gitops style CI/CD.

Spring Cloud Kubernetes

Ryan Baxter, Software Engineer, Pivotal

Read more
Kubernetes has become the defacto Container-As-A-Service provider in the industry. See how Spring Cloud Kubernetes integrates with Config Maps and Secrets for providing secure configuration to Spring Boot applications in a seamless manner. See also how integration work with the Spring Cloud DiscoveryClient and when it would be useful to use it. We will also talk about integration with Spring Cloud Sleuth and Zipkin for distributed tracing. See how Spring Cloud Gateway can perform as a Kubernetes ingress router.

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.

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.

How Fast is Spring?

Dave Syer, Senior Consulting Engineer, Pivotal

Read more
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.

Spring Security 5.1 by Example

Rob Winch, Spring Security, Session, & LDAP Project Lead, Pivotal

Read more
In this talk we will be taking an insecure, set of microservices and gradually apply Spring Security 5.1 to it. Along the way we will highlight the new features in Spring Security 5.1 including password storage migrations, new OAuth2 Client and Resource Server Support, and more. Whether you are new to Spring Security or a seasoned Spring Security user, this presentation is a must.
