Data Migration at Scale with RabbitMQ and Spring Integration

This is your one stop shop introduction to get oriented to the world of reactive programming. There are lots of such intros out there even manifestos. We hope this is the one where you don't get lost and it makes sense. Get a definition of what "reactive" means and why it matters. Learn about Reactive Streams and Reactive Extensions and the emerging ecosystem around them. Get a sense for what going reactive means for the programming model. See lots of hands-on demos introducing the basic concepts in composition libraries using RxJava and Reactor.

Webinar–Reviewing Modern JavaScript Applications

Synopsys Software Integrity Group

This presentation contains a tutorial devoted to showing how Java developers can create rich multimedia applications with Kurento. Java developers will find natural Kurento development model, which is based on standard Java EE technologies and is inspired on the WWW Servlet model. If you have ever developed a Web application, you may be familiar with this scheme. At the browser, HTML and JavaScript code is in charge of user interaction and generates HTTP requests to the server. This code is usually programmed with the help of APIs such as jQuery, DOM, XHR or others. Upon reception, HTTP requests are processed by some kind of server side technology (e. g.. PHP, Java, Ruby, etc.) using service APIs providing features such as DB access, communications, transactions, XML parsing, and others. As a result, an HTTP response is issued and sent back to the client. Following this scheme, both server and client side APIs are just capabilities simplifying developer work and providing abstractions for programming faster and more efficiently. Kurento technologies adapt to the Web development model so that, from a programmer perspective, Kurento can be seen just as an additional set of APIs. Developers does not need to learn novel programming schemes and can reuse all their knowledge and previous background on WWW application development. When you need multimedia, just use Kurento APIs. For the rest, use your preferred APIs or reuse previous code. Kurento APIs have been designed for simplicity and Web developers will find them familiar and intuitive. Most of the low level details related to codecs, formats, protocols, profiles and containers are abstracted by the framework. Programmers just concentrate on specifying the sequence of processing steps that they want to execute on the media flows.

Developing rich multimedia applications with Kurento: a tutorial for Java Dev...

Luis Lopez

This is a presentation specifically created for the GSMA interest group on WebRTC. This presentations introduces Kurento from the perspective of operators. Kurento is a multimedia development framework. It has been created to ease the life of multimedia application developers. Using multimedia capabilities such as embedding a video onto your app or establishing a video conferencing link between two clients may be tricky, but there is no rocket science there. However, for applications requiring more advanced features things quickly get unmanageable. If you have been involved in multimedia projects, you probably know that features such as interoperable group communications, different communication roles (e. g.. publishers/viewers), video transforming and transcoding, video storage and tagging, integration into legacy video/voice infrastructures, computer vision, augmented reality, integration with external systems and databases and many others, pose quite a complex challenge, which usually requires huge expertise and effort. Specially when real-time communications are involved. If this is your case, Kurento will help you.

The future of multimedia communications and services: Kurento and it's role

Luis Lopez

As HTML5 video gains widespread adoption, we have seen significant advances in a short period of time. While EME and webRTC get a lot of attention, they are not the only tools with the potential to change the way we stream video in the future. In this presentation, we discuss some of the new browser APIs that could usher in the next generation of HTML5 video: from the browser Fetch API to Service Workers to network side improvements such as HTTP2 and QUIC. This presentation first discusses what these new APIs can do, as well as the advantages and possible drawbacks of using them. We then examine the state of the art and obstacles to adoption (standardization, politics, etc.) to offer broadcasters a glimpse of what the future will hold.

The next generation of protocols and APIs that could change streaming video

Erica Beavers

Creating WebRTC applications is simple, but making them scalable in a robust and efficient way isn’t. Due to this, many application developers do not dare to use their own infrastructures and instead prefer to leverage third party clouds for creating their scalable WebRTC services. These clouds are private and usually expose some kind of API that developers consume for accessing WebRTC communication capabilities such as group-communications, media recording or media transcoding. This model is very convenient for creating simple vertical applications, but it also has some drawbacks. First, these clouds billing models are based on pay-per-minute schemes that are not always compatible with the business models desired by application developers. Second, the exposed APIs tend to be restrictive and limit the freedom of developers for innovating. Third, these clouds, being fully private, cannot be extended or customized for specific needs developers may have. In this talk, we propose an alternative solution to private WebRTC PaaS models based on leveraging novel cloud orchestration technologies such as Cloud Formation or Heat Templates for enabling developers to create their very own platform on top of public clouds. We analyze the technological ingredients required for enabling such models and present some experiments and production deployments showing how any developer may bring her own IaaS cloud for growing on it a full featured WebRTC platform with elastic scalability and full control on the billing and on the underlying technology evolution.

An edge gateway is an essential piece of infrastructure for large scale cloud based services. This presentation details the purpose, benefits and use cases for an edge gateway to provide security, traffic management and cloud cross region resiliency. How a gateway can be used to enhance continuous deployment, and help testing of new service versions and get service insights and more are discussed. Philosophical and architectural approaches to what belongs in a gateway vs what should be in services will be discussed. Real examples of how gateway services, built on top of Netflix's Open source project, Zuul, are used in front of nearly all of Netflix's consumer facing traffic will show how gateway infrastructure is used in real highly available, massive scale services.

SpringOne Platform 2016 Speakers: Craig Walls; Spring Social Lead, Pivotal. Roy Clarkson; Spring Mobile Lead, Pivotal. Developing cloud native applications presents several challenges. How do microservices discover each other? How do you configure them? How can you make them resilient to failure? How can you monitor the health of each microservice? Spring Cloud addresses all of these concerns. Even so, you still must explicitly develop your own discovery server, configuration server, and circuit breaker dashboard for monitoring the circuit breakers in each microservice. Spring Cloud Services for Pivotal Cloud Foundry picks up where Spring Cloud leaves off, offering a discovery server, configuration server, and Hystrix dashboard as services that can be bound to applications deployed in Pivotal Cloud Foundry, leaving you to focus on developing the services that drive your application. In this talk, we will introduce the capabilities provided by Spring Cloud Services and demonstrate how it makes simple work of deploying cloud native applications to Cloud Foundry.

SpringOne Platform 2017 Mark Michael, Pivotal; Glenn Oppegard, Pivotal "Ever wonder what it takes to move a popular, high traffic web application from a traditional hosting environment to Cloud Foundry running on Amazon Web Services, and then moving it to Google Cloud Platform, without customers noticing? In this talk, we’ll share our experience from beginning to end, starting with making the Pivotal Tracker code base cloud friendly, configuring app deployment and data services on Amazon Web Services, properly scaling the foundation and data services prior to going live and doing a seamless cutover in less than 3 hours. Then how and why we did it all again by moving to Google Cloud Platform...in a fraction of the time thanks to Cloud Foundry. We’ll also share the benefits we’ve experienced by being on Cloud Foundry, including how it’s allowed us to fully automate our build, acceptance and Concourse deployment process inching ever closer to continuous delivery. Most importantly, we’ll reveal how it’s changed the way we do DevOps and in the process freed up countless developer hours to focus on improving our product instead of operations."

SpringOne Platform 2016 Speaker: Alex Ley; Product Manager, Pivotal Building a continuous delivery pipeline for your micro-service based architecture can be a real challenge when using more conventional CI systems like Jenkins and GoCD. How do you get a clear picture of the CI workflow and status? What artifact was deployed and when? How is this all configured? Introducing Concourse (https://concourse.ci), an open source pipeline based CI system that focuses on simplicity, usability and reproducibility. It offers isolated builds, a range of integrations and is built upon a proven technology stack from Cloud Foundry. This talk will demonstrate creating a continuous delivery pipeline for a Spring microservice-based application that uses Spring Cloud. You will see how the pipeline tests services, integrates and then blue / green deploys to Cloud Foundry. Expect to rush to your laptop to try out Concourse after this session!

SpringOne Platform 2016 Speaker: Thomas Gamble; Director, Development, Home Depot Your team is excited about getting started with Spring Boot and Cloud Native, but you're not entirely sure you're ready to have the team continuously delivering to prod using cf push from their local desktops. The freedom of cloud native development can be very empowering for developers, but it shouldn't be something that terrifies the operations and security teams. We'll discuss how you can setup a fast and reliable deployment process, as well as some interesting things to thing about in the future. One of the most well known descriptions of these new paradigms is the Twelve Factor App (12factor.net), which describes elements of cloud native applications. Many of these needs are squarely met through the Spring Framework, others require support from other systems. In this session we will examine each of the twelve factors and present how Spring, and platforms such as Cloud Foundry satisfy them, and in some cases we’ll even suggest that responsibility should shift from Spring to platforms. At the conclusion you will understand what is needed for cloud‐native applications, why and how to deliver on those requirements.

We deployed five new Grails micro services into production roughly a year ago. I will describe how Grails fits into our larger polyglot architecture. And go through our experiences building and maintaining these micro services. Showing what items we reused and standardized across the application, and the pitfalls we have encountered. I will also work through some of the supporting technologies including Puppet, Vagrant, OpenStack, Spring Integration, and ActiveMQ and how we are using them with Grails. By the end of the talk you should have the knowledge to evaluate if Grails micro services are good for your team and what support you will need to put in place before you can take the micro service approach.

SpringOne Platform 2017 Gunnar Hillert, Pivotal You have the goal to migrate your project from AngularJS 1.x to Angular 4. This should be straightforward, except you are realizing that your 3 year old technology stack is totally outdated (Grunt, RequireJS, Bower et al). Furthermore, you are using an older AngularJS 1.x version and your architecture does not conform with the latest 1.x architectural recommendations. At this point things start to look daunting. In this talk we discuss the challenges, experiences and reasons for migrating the Spring Cloud Data Flow Dashboard from using AngularJS 1.x to Angular 4. We also show how we effectively integrate our Angular front-end with Spring Boot.

As presented at SpringOne2GX 2015 in Washington, DC. Lattice is a cloud-native application platform that enables you to run your applications in containers like Docker, on your local machine via Vagrant. Lattice includes features like: Cluster scheduling HTTP load balancing Log aggregation Health management Lattice does this by packaging a subset of the components found in the Cloud Foundry elastic runtime. The result is an open, single-tenant environment suitable for rapid application development, similar to Kubernetes and Mesos Applications developed using Lattice should migrate unchanged to full Cloud Foundry deployments. Lattice can be used by Spring developers to spin up powerful micro-cloud environments on their desktops, and can be useful for developing and testing cloud-native application architectures. Lattice already has deep integration with Spring Cloud and Spring XD, and you’ll have the opportunity to see deep dives into both at this year’s SpringOne 2GX. This session will introduce the basics: Installing Lattice Lattice’s Architecture How Lattice Differs from Cloud Foundry How to Package and Run Your Spring Apps on Lattice

SpringOne Platform 2016 Speaker: Kenny Bastani; Developer Advocate, Pivotal. Cloud Foundry is a powerful structured platform. For many organizations their first experience with Cloud Foundry feels like jumping in a time machine and emerging in a world where the automations are done and--even more surprising--they work! But that’s just the beginning. Cloud Foundry is a trustworthy, capable foundation you can build upon. It’s power lies in the flexibility provided through a structured, clear framework for extension. That’s what I want to show you in this talk. There are several supported mechanisms for extending the platform. In this talk we’ll consider each method and which problem areas they address well. We’ll cover everything from user-provided services to first class services managed by BOSH. You may be extending the platform to provide unique, new services to your users; or to bridge cloud-native applications running on Cloud Foundry with existing data centers and tools. No matter your use case you’ll gain a valuable understanding of the extensibility of the platform itself to truly make it your own. Cloud Foundry gives platform operators and platform engineers an incredible framework for delivering transformative value to application developers. Learn how in this talk.

Improvements in RabbitMQ

RabbitMQ Data Ingestion at Craft Conf

Do you need to process thousands of images in the background for your web app? Do you need to share data across multiple applications, probably written in different languages and sitting at different servers? Your real time data feed is becoming slow because you are polling the database constantly for new data updates? Do you need to scale information processing during peek times? What about deploying new features with zero downtime? If any of these problems sound familiar then you probably need to use messaging in your application. In this talk I will introduce RabbitMQ, a messaging and queue server that can help us tackle those problems. We will learn the benefits of a Queue Server and see how to integrate messaging into our applications. With this talk we hope that the term 'decoupling' gets a new, broader, meaning.

Dissecting the rabbit: RabbitMQ Internal Architecture

Introduction to RabbitMQ | Meetup at Pivotal Labs

We've been told many times that we should write unit tests for our code. We have read the theory and we have applied automatic testing to our projects, sometimes successfully but often times not so. Why it seems to be so hard to test our code? However we look at it, automatic testing doesn't work like a "plug & play" peripheral. It just doesn't seem to fit with our project. A dependency is missing here; we have a hard to mock object there; and so on. What is _that_ thing we might be doing wrong but we fail to notice? In this talk we will argue that the problem lays in our code, in its structure, in the way we pass data around and even how we write for loops! This won't be your everyday "code quality" tech talk, since we are going to attack the problem of code quality from different points of view and paradigms like Functional Programming and the Unix philosophy of simplicity and reuse.

In the thrilling conclusion to 2023, ransomware groups had a banner year, really outdoing themselves in the "make everyone's life miserable" department. LockBit 3.0 took gold in the hacking olympics, followed by the plucky upstarts Clop and ALPHV/BlackCat. Apparently, 48% of organizations were feeling left out and decided to get in on the cyber attack action. Business services won the "most likely to get digitally mugged" award, with education and retail nipping at their heels. Hackers expanded their repertoire beyond boring old encryption to the much more exciting world of extortion. The US, UK and Canada took top honors in the "countries most likely to pay up" category. Bitcoins were the currency of choice for discerning hackers, because who doesn't love untraceable money?
