Continuous Delivery is the trend process of the moment. It helps companies to deliver their products in a faster and trustful way. Immutable Server is not a new concept. However, thanks to advent of IaaS like AWS, it becomes easier embrace the idea and use its amazing advantages. Mindera tries to adopt these concepts in their projects. It has never been so cool to watch our CD pipeline build and destroy our application’s infrastructure. It's so awesome that we want to share it with you.

Slides from my Jfokus 2015 talk Abstract: ====== App deployment and server setup are complex, error-prone and time-consuming. They require OS installers, package managers, configuration recipes, install scripts, server hardening and more. But... Is this really necessary? What if we could start over and radically simplify all this? What if, within seconds, we could wrap our app into the smallest machine required to run it and transfer this machine unchanged from our laptop to the cloud? How do the various platforms and tools like AWS, Docker and Boxfuse fit into this picture? When should you use them? This talk is for developers and architects wishing to radically improve and simplify how they deploy their applications. It takes Continuous Delivery to a whole new level. Welcome to Immutable Infrastructure. This is the new black.

"A lot of people use Jenkins, it’s probably the most used CI tool for private use. It's robust, versatile and not at all complex to use. However it lacks job management usability at scale. When you have to deal with more than 10 jobs, it starts to be a boring and error prone task. What about using the same strategy that new CI tools are using? Like Travis for instance. Wouldn’t it be fantastic if we had a file in our code repository that Jenkins could recognise and execute jobs accordingly? I'm proposing a different way of using Jenkins. Using an open source tool called Jenkins Job Builder and by 'eating our own dog food', I will share a versionable, modular and easy way of managing your Jenkins jobs. This enables you to configure not only CI but also CD with just a YAML file." http://mindera.com/blog/post/jenkins-a-la-travis

Managing your Docker image continuously with Concourse CI

Toshiaki Maki

In this talk we will discuss how we enabled decomposition of one of our 500+ system components into a continuously deployed microservice cluster. Our platform is comprised of Apache Mesos/Marathon, Docker, and a number of local services including Consul for service discovery, Logstash for diskless logging, and a custom metrics forwarder to Graphite. Building on this, we'll detail our CI pipeline using Jenkins workflows to build and publish microservices as Docker images, test and deploy via Marathon/Mesos, and automated change tickets. Finally, we'll discuss lessons learned from building our own enterprise PaaS and scaling it out to a large organization.

What kind of first impression is your web or mobile application making? It may not be what you would hope. Many SaaS applications’ free trials are used only once. Sources say 80-90% of mobile apps are downloaded, used once and deleted. First time user experience, while critical to product success, may not be getting the attention it deserves. During onboarding, a first-time user must transition from novice to an engaged, active and repeat user. They must immediately recognize what they can do, how they can do it, and why it benefits them. This talk presents design principles for great onboarding experiences that engage and inform new users, helping them become productive quickly. We will discuss how to convey your value proposition, guide setup, remove barriers, streamline initial tasks via smart defaults, provide walkthroughs, and instruct at the point of use, drawing on examples from web applications, mobile apps, and devices.

How can you tackle the process of updating a mature interface? In this presentation, I will discuss our team’s approach to quickly transform the look and feel of GoToMeeting, GoToWebinar and GoToTraining for Mac over a period of four months. Learn how we kept our project on track by saying no to all but the most essential improvements, and how we incorporated design feedback without falling prey to out-of-scope requirements. I'll explain my design process and how I supported the team in my role as scrum master. You will see visual design changes that were tried and discarded, and most importantly, what impact the visual changes had on our user community. This talk will cover what can realistically be done in a short period of time to improve your interface without overcommitting, and where to go after the first release.

IPv6 is the most recent version of the Internet Protocol (IP), and was developed by IETF to overcome the inevitable exhaustion of IPv4 addresses. In order to simplify the transition towards IPv6, the protocol iterated very little on how IPv4 operates other than offering more address space. This inadvertently produced the exact opposite of the intended effect: with no compelling new features for anyone outside of network engineering, IPv6 deployment has been hampered for decades, as developers find increasingly creative ways of efficiently using IPv4 address space rather than bearing the cost of transition. In this talk, Fastly Network Engineer João Taveira discusses these protocol design failures and instead explain how Fastly re-architected its infrastructure around IPv6. By addressing IPv6 in a clean-slate manner, Fastly avoided perpetuating many of the mistakes of IPv4, and the resulting network architecture has the potential to significantly affect the performance, resilience, and economics of content delivery.

Isn't it amazing? Stakeholders drop software on our desks and expect us to test it—without any requirements, design, or product knowledge whatsoever. About the only clear thing is the absurd and unrealistic deadline. We are expected to bend over backward, spread magic pixie dust, and heroically test quality into a product we have never heard of before. But testing in the dark is not impossible, and as Rob Sabourin shows, it can even be a very valuable and fun experience. Learn strategies to emerge from a murky fog into clear, meaningful quality insights. Leverage unlikely sources about what stakeholders care about and what users really need the software to do. Rob introduces you to methods of reconnaissance-style, charter-driven, and session-based exploratory testing and helps you provide meaningful estimates to stakeholders with minimal hard information about the software under test. Rob shares recent experiences testing in the dark on chaotic and turbulent projects, turning his product ignorance into a testing superpower. Join Rob’s quest to find important bugs fast while testing in the dark—and you, too, will see the light!

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?

Tracing the root cause of a performance issue requires a lot of patience, experience, and focus. It’s so hard that we sometimes attempt to guess by trying out tentative fixes, but that usually results in frustration, messy code, and a considerable waste of time and money. This talk explains how to correctly zoom in on a performance bottleneck using three levels of profiling: distributed tracing, metrics, and method profiling. After we learn to read the JVM profiler output as a flame graph, we explore a series of bottlenecks typical for backend systems, like connection/thread pool starvation, invisible aspects, blocking code, hot CPU methods, lock contention, and Virtual Thread pinning, and we learn to trace them even if they occur in library code you are not familiar with. Attend this talk and prepare for the performance issues that will eventually hit any successful system.
