20 mins to Faking the DevOps Unicorn by Matt williams, Datadog

Docker, Inc.

Something changed in job ads over the last few years: everyone wants the DevOps Unicorn. What is that and why did this happen? You probably have a good amount of what is in that description, but is there an easy way to fill in the rest of the 100%? It turns out that it is possible to fake your way to being a DevOps Unicorn. All that you need is a way to know which metrics are the most important. And to know that you need a framework that applies everywhere. No really, it's easier than you think. There is some work needed on your part, but just a few minutes is enough to get started. In this 20 minute session, we will cover what changed in the market, what the framework looks like, and how to apply it to all of the containerized applications you need to monitor.

DCEU 18: From Monolith to Microservices

Docker, Inc.

Jeff Nickoloff - Co-founder, Topple Growth can be challenging to address once monolithic systems begin to fail under strain or internal software development processes begin to slow the release cadence. Many organizations are looking to microservices architecture to solve these application issues, whether they plan to write new applications or rewrite the monoliths into microservices. This talk will highlight the common technical and cultural issues that will make microservice architectures a challenge to adopt and maintain. Issues include impact of Dunbar's Number and Conway's Law, build-time vs runtime continuous integration, evolution of testability, API versioning impact, logistics overhead, artifact management, and strategies for iteration in a distributed environment. Attendees will learn: - How and why microservice architectures and ownership end up falling along organizational lines (and why that is a good thing) - How we can learn from monolith tooling to inform our tooling in a microservice environment - How you can achieve operational excellence at scale taking a logistical approach with Docker.

Modern big data and machine learning in the era of cloud, docker and kubernetes

Slim Baltagi

There is a major shift in web and mobile application architecture from the ‘old-school’ one to a modern ‘micro-services’ architecture based on containers. Kubernetes has been quite successful in managing those containers and running them in distributed computing environments. Now enabling Big Data and Machine Learning on Kubernetes will allow IT organizations to standardize on the same Kubernetes infrastructure. This will propel adoption and reduce costs. Kubeflow is an open source framework dedicated to making it easy to use the machine learning tool of your choice and deploy your ML applications at scale on Kubernetes. Kubeflow is becoming an industry standard as well! Both Kubernetes and Kubeflow will enable IT organizations to focus more effort on applications rather than infrastructure.

Interaction Latency: Square's User-Centric Mobile Performance Metric

ScyllaDB

Mobile performance metrics often take inspiration from the backend world and measure resource usage (CPU usage, memory usage, etc) and workload durations (how long a piece of code takes to run). However, mobile apps are used by humans and the app performance directly impacts their experience, so we should primarily track user-centric mobile performance metrics. Following the lead of tech giants, the mobile industry at large is now adopting the tracking of app launch time and smoothness (jank during motion). At Square, our customers spend most of their time in the app long after it's launched, and they don't scroll much, so app launch time and smoothness aren't critical metrics. What should we track instead? This talk will introduce you to Interaction Latency, a user-centric mobile performance metric inspired from the Web Vital metric Interaction to Next Paint"" (web.dev/inp). We'll go over why apps need to track this, how to properly implement its tracking (it's tricky!), how to aggregate this metric and what thresholds you should target.

GDG Cloud Southlake #34: Neatsun Ziv: Automating Appsec

James Anderson

The lecture titled "Automating AppSec" delves into the critical challenges associated with manual application security (AppSec) processes and outlines strategic approaches for incorporating automation to enhance efficiency, accuracy, and scalability. The lecture is structured to highlight the inherent difficulties in traditional AppSec practices, emphasizing the labor-intensive triage of issues, the complexity of identifying responsible owners for security flaws, and the challenges of implementing security checks within CI/CD pipelines. Furthermore, it provides actionable insights on automating these processes to not only mitigate these pains but also to enable a more proactive and scalable security posture within development cycles. The Pains of Manual AppSec: This section will explore the time-consuming and error-prone nature of manually triaging security issues, including the difficulty of prioritizing vulnerabilities based on their actual risk to the organization. It will also discuss the challenges in determining ownership for remediation tasks, a process often complicated by cross-functional teams and microservices architectures. Additionally, the inefficiencies of manual checks within CI/CD gates will be examined, highlighting how they can delay deployments and introduce security risks. Automating CI/CD Gates: Here, the focus shifts to the automation of security within the CI/CD pipelines. The lecture will cover methods to seamlessly integrate security tools that automatically scan for vulnerabilities as part of the build process, thereby ensuring that security is a core component of the development lifecycle. Strategies for configuring automated gates that can block or flag builds based on the severity of detected issues will be discussed, ensuring that only secure code progresses through the pipeline. Triaging Issues with Automation: This segment addresses how automation can be leveraged to intelligently triage and prioritize security issues. It will cover technologies and methodologies for automatically assessing the context and potential impact of vulnerabilities, facilitating quicker and more accurate decision-making. The use of automated alerting and reporting mechanisms to ensure the right stakeholders are informed in a timely manner will also be discussed.

What Not to Document and Why_ (North Bay Python 2024)

Margaret Fero

We’re hopefully all on board with writing documentation for our projects. However, especially with the rise of supply-chain attacks, there are some aspects of our projects that we really shouldn’t document, and should instead remediate as vulnerabilities. If we do document these aspects of a project, it may help someone compromise the project itself or our users. In this talk, you will learn why some aspects of documentation may help attackers more than users, how to recognize those aspects in your own projects, and what to do when you encounter such an issue. These are slides as presented at North Bay Python 2024, with one minor modification to add the URL of a tweet screenshotted in the presentation.

Observability For You and Me with OpenTelemetry

Eric D. Schabell

Are you interested in dipping your toes in the cloud native observability waters, but as an engineer you are not sure where to get started with tracing problems through your microservices and application landscapes on Kubernetes? Then this is the session for you, where we take you on your first steps in an active open-source project that offers a buffet of languages, challenges, and opportunities for getting started with telemetry data. The project is called openTelemetry, but before diving into the specifics, we’ll start with de-mystifying key concepts and terms such as observability, telemetry, instrumentation, cardinality, percentile to lay a foundation. After understanding the nuts and bolts of observability and distributed traces, we’ll explore the openTelemetry community; its Special Interest Groups (SIGs), repositories, and how to become not only an end-user, but possibly a contributor.We will wrap up with an overview of the components in this project, such as the Collector, the OpenTelemetry protocol (OTLP), its APIs, and its SDKs. Attendees will leave with an understanding of key observability concepts, become grounded in distributed tracing terminology, be aware of the components of openTelemetry, and know how to take their first steps to an open-source contribution! Key Takeaways: Open source, vendor neutral instrumentation is an exciting new reality as the industry standardizes on openTelemetry for observability. OpenTelemetry is on a mission to enable effective observability by making high-quality, portable telemetry ubiquitous. The world of observability and monitoring today has a steep learning curve and in order to achieve ubiquity, the project would benefit from growing our contributor community.
