How to deploy PHP projects with docker

Ruoshi Ling

OSv is the new open source unikernel technology that combines the power of virtualization and micro-services architecture. This combination allows unmodified applications to be packaged just like Docker containers while at the same time outperform bare-metal deployments. Yes. You've heard it right: for the first time ever we can stop asking the question of how much performance would I lose if I virtualize. OSv lets you ask a different question: how much would my application gain in performance if I virtualize it. This talk will start by looking into the architecture of OSv and the kind of optimizations it makes possible for native, unmodified applications. We will then focus on JVM-specific optimizations and specifically on speedups available to micro-service oriented applications when they are being deployed on OSv.

In this session, we'll discuss: - What’s Apache Camel: An overview of Camel and what you use it for and why you should care. - Camel 3: Demos of how Camel 3, Camel K and Camel Quarkus all work together, and will provide insights into Camel’s role in the next major release of Red Hat Integration products. - Camel K: This serverless integration platform provides low-code/no-code capabilities, where integrations can be snapped together quickly using the powers from integration patterns and Camel’s extensive set of connectors. - Camel Quarkus: Using Knative (the fast runtime of Quarkus) and Camel K brings awesome serverless features, such as auto-scaling, scaling to zero, and event-based communication, with great integration capabilities from Apache Camel. You will also hear about the latest Camel sub-project Camel Kafka Connectors which makes it possible to use all the Camel components as Kafka Connect connectors. Finally we bring details of the roadmap for what is coming up in the Camel projects. And after the presentation we have about 30 minutes of QA answering all the questions from the audience.

OSv is the revolutionary new open source technology that combines the power of virtualization and micro-services architecture. This combination allows unmodified applications deployed in a virtualized environment to outperform bare-metal deployments. Yes. You've heard it right: for the first time ever we can stop asking the question of how much performance would I lose if I virtualize. OSv lets you ask a different question: how much would my application gain in performance if I virtualize it. This talk will start by looking into the architecture of OSv and the kind of optimizations it makes possible for native, unmodified applications. We will then focus on JVM-specific optimizations and specifically on speedups available to big data management distributed applications. Finally, we will look into the relationship between OSv and Docker and how that layering can help make OSv a secret sauce for turbo-charging Cloud Foundry application deployments.

Writing iOS apps in Javascript is not a new idea, anymore, at least since companies like Appcelerator (Titanium) built entire business models around corresponding frameworks. And yet, Apple manages to open up two exciting new possibilities during the WWDC 2013: The release of the JavaScriptCore Framework as a public API on iOS and OS X, as well as the announcement of an Objective-C to Javascript Bridge. I'd like to talk to you about my experiences with these new bridge-technologies, the new ways in which you can use them and finally present to you my own project; Node.app — a Node.js implementation for iOS.

Talk at rootconf - A conference at Bangalore for sysadmins. Gist of the talk:- Puppet is a great configuration management tool and git is great at version controlling.AWS lets you create instances in few clicks. But when it comes to large deployments only automation(where tools come together) can make you productive and happy. I will take you through following.. Fog - The Ruby cloud services library and how it helps you to create vendor neutral cloud deployments, Puppet- Multi region puppet masters, Ruby- How Ruby pulls the strings together in EC2/ELB/RDS creation, Security group creation, IP authorization, Route53 DNS etc, Git- how we use git to version control deployment configs/configurations.

Ansible is a Configuration Management System that is very simple to use, because of its straightforward and robust model for managing automation and it’s low barrier to entry for ease of use in both development and production. During OpenStack development, Ansible can be used in conjunction with Vagrant and Devstack to manage complex, multi-node development environments with relative ease. In this presentation, Juergen Brendel and David Lapsley review Ansible and provide some sample playbooks to get developers up and running quickly. They also describes how to use Ansible, Vagrant, Devstack, and OpenStack to accelerate OpenStack development cycles.

Learn you some Ansible for great good!

iOS Automation rapidly changed due to the evolution of Apple automation frameworks and Calabash community support. One year ago, we parallelised our iOS testing with multiple desktops – a large improvement in performance. Here is an account of the subsequent changes, including the removal of multiple desktops and the adoption of Apple’s new XCTest framework. The automation community (Appium, Calabash etc.) faced a new challenge: how could we create iOS Automation Infrastructure with the new XCTest Framework? I adopted Facebook solution (FBSimCtl and WebAgentDriver) into the multi-simulators approach. In this talk, I will discuss the full evolution path to Facebash Approach based on multi-simulators, Calabash server and Facebook Web Driver Agent.

When you’re building (micro)services, you have lots of framework options. Spring Boot is no doubt a popular choice. But there’s more! Take Quarkus, a framework that’s considered the rising star for Kubernetes-native Java. It always depends on what's best for your situation, but how to choose the best solution if you're comparing 2 frameworks? Both Spring Boot and Quarkus have their positives and negatives. Let us compare the two by live coding a couple of common use cases in Spring Boot and Quarkus. After this talk, you’ll be ready to get started with Quarkus yourself, and know when to select Quarkus or Spring Boot.

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. About authorWith two decades of experience, Victor is a Java Champion working as a trainer for top companies in Europe. Five thousands developers in 120 companies attended his workshops, so he gets to debate every week the challenges that various projects struggle with. In return, Victor summarizes key points from these workshops in conference talks and online meetups for the European Software Crafters, the world’s largest developer community around architecture, refactoring, and testing.

Webinar Recording: https://www.panagenda.com/webinars/why-teams-call-analytics-is-critical-to-your-entire-business Nothing is as frustrating and noticeable as being in an important call and being unable to see or hear the other person. Not surprising then, that issues with Teams calls are among the most common problems users call their helpdesk for. Having in depth insight into everything relevant going on at the user’s device, local network, ISP and Microsoft itself during the call is crucial for good Microsoft Teams Call quality support. To ensure a quick and adequate solution and to ensure your users get the most out of their Microsoft 365. But did you know that ‘bad calls’ are also an excellent indicator of other problems arising? Precisely because it is so noticeable!? Like the canary in the mine, bad calls can be early indicators of problems. Problems that might otherwise not have been noticed for a while but can have a big impact on productivity and satisfaction. Join this session by Christoph Adler to learn how true Microsoft Teams call quality analytics helped other organizations troubleshoot bad calls and identify and fix problems that impacted Teams calls or the use of Microsoft365 in general. See what it can do to keep your users happy and productive! In this session we will cover - Why CQD data alone is not enough to troubleshoot call problems - The importance of attributing call problems to the right call participant - What call quality analytics can do to help you quickly find, fix-, and prevent problems - Why having retrospective detailed insights matters - Real life examples of how others have used Microsoft Teams call quality monitoring to problem shoot problems with their ISP, network, device health and more.

The action of the next cyber saga takes place in the mystical lands of the Asia-Pacific region, where the main characters began their digital activities in the middle of 2021 and qualitatively strengthened it in 2022. Corporate espionage, document theft, audio recordings, and data leaks from messaging platforms were all a matter of one day for Dark Pink. Their geographical focus may have started in the Asia-Pacific region, but their ambitions knew no bounds, targeting a European government ministry in a bold move to expand their portfolio. Their victim profile was as diverse as a UN meeting, targeting military organizations, government agencies, and even a religious organization. Because discrimination is not a fashionable agenda. In the world of cybercrime, they serve as a reminder that sometimes the most serious threats come in the most unassuming packages with a pink bow.
