Too many websites make it too the news when they fail to deliver, e.g: eCommerce when they go down on Cyber Monday, Tax Software on Tax Day or Online Banking when people want to check on their latest pay check. In this presentation - presented at several Web Performance, Java, .NET, ... Meetups I walk through the most common performance mistakes people made in recent history. I explain in technical detail what the problem was and how to find these problems earlier as you dont want to wait until your site crashes and you end up in the news.

Application Quality Gates in Continuous Delivery: Deliver Better Software Fas...

Andreas Grabner

BTD2015 - Your Place In DevTOps is Finding Solutions - Not Just Bugs!

Andreas Grabner

This is about leveling-up and REVOLUTIONIZING Testing as part of your Agile/DevOps Transformation. You can contribute more than testing functionality. You need to Level-Up your skill set by understanding the apps you are testing. # Images, # JS Files, # SQL Statements, Connection Pool Utilization and Garbage Collection Activity have to be added to your portfolio. Check these metrics when you do your functional testing and report regressions to your engineers even though the functionality is still good. But you just uncovered an Architectural regression that will lead to a scalabilty and performance problem. Finding these problems early will eliminate a lot of wasted and unplanned time later on in the lifecycle. that is your contribution to delivering software faster with better quality

Mobile User Experience:Auto Drive through Performance Metrics

Andreas Grabner

Believe it or not - 85% of mobile apps are removed after first usage! In this presentation - given at the APM Meetup in Singapore in April 2015 - I talked about the challenges, best practices and especially metrics to avoid this situation. Key Points of the Presentation The two key trends "Internet of Things" and "DevOps" play a big role in our life when we talk about User Experience and especially mobile user experience. In this presentation I tell you what metrics to use to make sure you deliver your ideas faster to your mobile end users but also ensuring the right quality and user experience so that your users stay loyal and dont delete the mobile app after first usage.

This is the presentation given for the Docker Meetup in Cordoba, Argentina. Recording should soon be up on http://www.meetup.com/Docker-Cordoba-ARG/events/226995018/ Key Takeaways: Pick your Metrics! Automate It! Fail Bad Builds Faster! Deliver Faster with Better Quality! To the Docker Audience my main point was that: Just adding Docker doesn't give you free performance and scalability of your app. I walk through many examples of failing apps. What are the metrics that highlight the problem and how to automatically detect bad builds by looking at these Metrics along your Pipeline.

How to explain DevOps to your mom

Andreas Grabner

These are the slides used in my #devone (www.devone.at) keynote presentation: DevOps is one of the most abused and overrated marketing terms in the last years! That’s not an alternative fact! It’s just Andi’s opinion! Yet - it is a very real thing that allowed many software companies to transform the way they think about software engineering. DevOps can mean something totally different thought depending on who you are and what type of business your company is doing. To clarify things, Andi gives us insights on how he explains the benefits to “DevOps Newbies” and how software companies around the world implement it in their own ways. Andi will answer: What does it really mean for developers, testers and operators? What will change? How does Facebook deploy twice a day without big issues? How does DevOps work in financial, government or healthcare where you have tight regulations? Does it mean Devs are responsible for Ops? Does it only work in the cloud? Or can we apply it to “old fashioned” on premise software as well? Learn for yourself and make up your own mind on whether DevOps is just a marketing term or something that can benefit you!

DevOps Days Toronto: From 6 Months Waterfall to 1 hour Code Deploys

Andreas Grabner

Slides used for https://www.devopsdays.org/events/2017-toronto/program/andreas-grabner/ In 2011 we delivered 2 major releases of our on premise enterprise software. Market, technology and customer requirements forced us to change that in order to remain competitive. Now – in 2017 - we are deploying and providing feature releases every 2 weeks for both our on premise and SaaS-based offering. We deploy 170 SaaS production changes per day and have a DevOps pipeline that allows us to deploy a code change within 1h if necessary. To increase quality, we built and provide a DevOps pipeline that currently executes 31000 Unit & Integration Tests per Hour as well as 60h UI Tests per Build. Our application teams are responsible end-to-end for their features and use production monitoring to validate their deployments which allows them to find 93% of bugs in production before it impacts our end users. In this session I explain how this transformation worked from both “Top Down” as well as “Bottom Up” in our organization. A key component was the 4 people strong DevOps Team who developed and “sell” their DevOps Pipeline to the globally distributed application teams. I will give insights into how our pipeline enables application teams to design, code, test and run a new feature for our user base. I will also talk about the “dark moments” as change is never without friction. Both internally as well as with our customers who also had to get used to more rapid changes.

JavaOne - Performance Focused DevOps to Improve Cont Delivery

Andreas Grabner

These are the slides of my JavaOne presentation. The abstract goes like this: How do companies developing business-critical Java enterprise Web applications increase releases from 40 to 300 per year and still remain confident about a spike of 1,800 percent in traffic during key events such as Super Bowl Sunday or Cyber Monday? It takes a fundamental change in culture. Although DevOps is often seen as a mechanism for taming the chaos, adopting an agile methodology across all teams is only the first step. This session explores best practices for continuous delivery with higher quality for improving collaboration between teams by consolidating tools and for reducing overhead to fix issues. It shows how to build a performance-focused culture with tools such as Hudson, Jenkins, Chef, Puppet, Selenium, and Compuware APM/dynaTrace

Tar syndrome group 6

Joselle Balasa

TAR syndrome is a rare autosomal recessive disorder characterized by the absence of the radius bone in the forearm and very low platelet counts. It affects males and females equally and is estimated to occur in 1 in 250,000 births. Symptoms include bruising and bleeding due to low platelet levels, as well as potential heart, kidney, or joint problems. Diagnosis involves x-rays and blood tests at birth. Treatment focuses on managing bleeding episodes through platelet transfusions and splinting to improve arm function.

This document discusses neonatal thrombocytopenia, defined as a platelet count below 150,000/uL in newborns. It can be caused by decreased platelet production in sick or premature infants, increased platelet destruction through immune or consumptive means, or platelet sequestration in the spleen. The two main types are neonatal alloimmune thrombocytopenia, caused by maternal antibodies crossing the placenta, and neonatal autoimmune thrombocytopenia, occurring in infants of mothers with immune thrombocytopenia. Clinical presentation and treatment involve monitoring for bleeding and administering IVIG when needed.

Alport syndrome. group 7

Joselle Balasa

Alport syndrome is an inherited disorder caused by mutations in collagen genes that damage the tiny blood vessels in the kidneys. It most often affects males and can progress to end-stage renal disease at an early age. Symptoms include blood in the urine, hearing and vision loss, and swelling in the legs. Fechtner syndrome is a rare variation characterized by enlarged blood platelets, kidney inflammation, deafness, and abnormal white blood cells caused by a mutation in the MYH9 gene. Symptoms include cataracts, deafness, nephritis, kidney disease, and excessive bleeding due to low platelet count. Both conditions can lead to kidney failure and require treatments like dialysis and transplant.

Background singers

13jkjordan

Background singers provide backup vocals for other artists on recordings and live performances. They must be able to learn songs quickly, harmonize with new groups, and switch between different musical styles in a single day. Pay varies depending on the type and length of work but successful background singers can earn over $100,000 per year. There are many opportunities for background singers, though breaking into work with famous artists is difficult and requires passing auditions with bands and agents. Formal education is not required but some background singers obtain degrees or training to improve their skills and have alternatives if their music career does not work out.

Finally, he sketches two use-cases on how an application monitoring solution like Dynatrace can help reduce costs and improve software quality along the Continuous Delivery build pipeline.

DevOps: Find Solutions, Not More Defects

TechWell

The promise of DevOps is that we can push new ideas out to market faster while avoiding delivering serious defects into production. Andreas Grabner explains that testers are no longer measured by the number of defect reports they enter, nor are developers measured by the lines of code they write. As a team, you are measured by how fast you can deploy high quality functionality to the end user. Achieving this goal requires testers to increase their skills. It’s all about finding solutions—not just problems. Testers must transition from reporting “app crashes” to providing details such as “memory leak caused by bad cache implementation.” Instead of reporting “it’s slow,” testers must discover “wrong hibernate configuration causes too much traffic from the database.” Using three real-life examples, Andreas illustrates what it takes for testing teams to become part of the DevOps transformation—bringing more value to the entire organization.

A Microservice Architecture for Big Data Pipelines

Daniel Mescheder

The document discusses using a microservice architecture approach for big data pipelines. It outlines some of the benefits of microservices like modularity, scalable development, and painless deployment. It then describes how these same principles can be applied to big data pipelines by developing them as independent and interchangeable "data modules". The presentation provides examples of how data modules can be containerized and work together like microservices to process streaming data. It concludes that a microservices-style architecture through data modules enables many of the same benefits for big data pipelines as it does for traditional applications.

The Unicorn Project and The Five Ideals (older: see notes for newer version)

Gene Kim

Updated version here (Dec 2019): https://www.slideshare.net/realgenekim/the-unicorn-project-and-the-five-ideals-updated-dec-2019 It is impossible to overstate how much I’ve learned since co-authoring The Phoenix Project, DevOps Handbook, and Accelerate. I’m so excited that after years of work, The Unicorn Project will be published later this year. This book is my attempt to frame what I’ve learned studying technology leaders adopting DevOps principles and patterns in large, complex organizations, often having to fight deeply entrenched orthodoxies. And yet, despite huge obstacles, they create incredibly effective and innovative teams that create beacons of greatness that inspire us all. In this book, we follow a senior lead developer and architect as she is exiled to the Phoenix Project, to the horror of her friends and colleagues, as punishment for contributing to a payroll outage. She tries to survive in what feels like a heartless and uncaring bureaucracy, forced to work within a system where no one can get anything done without endless committees, paperwork, change requests, and approvals. Decades of technical debt make even small changes difficult or impossible, often causing catastrophic outcomes and fear of punishment. I get tremendous delight and gratification that this book is not about the bridge crew of the Starship Enterprise -- instead, it is about redshirt engineers, which as it turns out, whose heroic work matters most to the long-term survival of almost every organization. In my previous books, I’ve focused on principles and practices (e.g., Three Ways, Four Types of Work). However, I’ve always wanted to describe the spectrum of cultural, experiential and value decisions we make that either enable greatness, or create chronic suffering and underperformance. They are currently as follows: • The First Ideal — Locality and Simplicity • The Second Ideal — Focus, Flow and Joy • The Third Ideal — Improvement of Daily Work • The Fourth Ideal — Psychological Safety • The Fifth Ideal — Customer Focus In this talk, I’ll share with you my goals and aspirations for The Unicorn Project, describe in detail the Five Ideals, along with my favorite case studies of both ideal and non-ideal, and why I believe more than ever that DevOps will be one of the most potent economic forces for decades to come.

KCD Munich - Cloud Native Platform Dilemma - Turning it into an Opportunity

Andreas Grabner

This talk was given at KCD Munich - July 17 2023 Abstract “Kubernetes is a platform for building platforms. It’s a better place to start: not the endgame”, tweeted by Kelsey Hightower in November 2017. 6 years later the Cloud Native Community is faced with 159 different CNCF projects to choose from. Entering CNCF can be overwhelming! Cloud Native Platform Engineering with white papers, best practices and reference architectures are here to convert this dilemma into an opportunity. Internal Developer Platforms (IDP) are being built as we speak enabling organizations to harness the power of Kubernetes as a self-service platform. Join this talk with Andreas Grabner, CNCF Ambassador, and get some insights on tooling, use cases and best practices so we can all fulfill the idea that Kelsey put out years ago.

OpenTelemetry For GitOps: Tracing Deployments from Git Commit to Production

Andreas Grabner

GitOps, with tools like Argo and Flux, are preferred platform tools managing configuration in cloud native environments. But it is hard to troubleshoot a failed deployment of a complex application as there is no built-in deployment lifecycle observability, standardized hooks nor the concept of an application vs individual workloads. The CNCF project Keptn addresses those challenges by extending the Kubernetes Pod scheduler to provide OpenTelemetry Traces and Prometheus metrics for end-2-end deployment observability. Keptn introduces automated application-aware pre- and post-deployment lifecycle hooks to enforce dependency checks, send notifications or evaluates SLOs that otherwise need a custom K8s operator. Join this talk and learn how the Keptn Lifecycle Toolkit (KLT) Operator extends observability into GitOps deployments and how it enables declarative deployment lifecycle orchestration!

Don't Deploy Into the Dark: DORA Metrics for your K8s GitOps Deployments

Andreas Grabner

This talk was given at Boston Cloud Native Meetup on Feb 9th 2023 DORA’s Four Key DevOps have gained much attention as they provide critical insights into an organization’s maturity in automating the delivery of high-quality software. Google provides a blueprint implementation which requires extending your existing delivery pipelines (Jenkins, Argo, Flux, GitHub, GitLab …) to push those metrics to an external database. While doable, many platform engineers we spoke to are seeking an alternative solution and more cloud-native approach. The CNCF project Keptn saw this as an opportunity to provide a K8s- & Cloud-Native solution that provides 100% coverage, WITHOUT changing pipelines and using OpenTelemetry as standard collection framework. Join this talk where Andi (Andreas) Grabner, DevRel at Keptn, will show you how you can use Keptn’s Lifecyle Toolkit to get your DORA metrics within 5 minutes. Andi also covers how the Lifecycle Toolkit brings application-awareness into your deployments and allows you to execute pre- and post-deployment checks as serverless functions – all declaratively as part of your existing K8s CRDs.

Observability and Orchestration of your GitOps Deployments with Keptn

Andreas Grabner

GitOps has become the default way to manage configuration in cloud native environments with tools like Argo or Flux keeping Git and K8s in sync. But GitOps lacks end-2-end traceability when GitOps operators make changes on the target environments. And as k8s lacks application awareness its hard to enforce pre- and post-deployment orchestration task such as sending notifications upon successful app delivery or validating all SLOs are healthy for a new version. The CNCF project Keptn is addressing those challenges by automatically providing End-2-End Observability through OpenTelemetry as well as introducing an application deployment lifecycle events enabling pre- and post-deployment checks natively on k8s. Keptn therefore extends your GitOps approach with the missing observability and orchestration needed for successful cloud native development.

A Guide to Event-Driven SRE-inspired DevOps

Andreas Grabner

This talk was given at the Online Kubernetes Meetup July 2020 as well as DevOps Fusion 2020. The talk discusses 3 major problems in current delivery and operations: too much time spent in delivery, hard to maintain monolithic delivery pipelines and a lack of auto-remediation of production problems The talk focuses on new approaches to solve these problems inspired by SRE practices and event-driven architectures. As an implementation for a new approach we use Keptn (www.keptn.sh) - a CNCF Open Source project.

Jenkins Online Meetup - Automated SLI based Build Validation with Keptn

Andreas Grabner

This document discusses automating SLI/SLO based build validation with Keptn and Jenkins. It begins by outlining the challenges of lengthy manual approval processes for promoting builds. It then provides inspiration from Google's SRE practices of using Service Level Indicators (SLIs), Service Level Objectives (SLOs), and Service Level Agreements (SLAs). The document demonstrates how Keptn can automate SLI/SLO-based evaluation to integrate with Jenkins pipelines. It includes demos of using Keptn for self-service SLI validation, automating existing Jenkins tests, and enabling performance as a self-service. The document promotes starting resources on GitHub and joining the Keptn community slack channel

Top Performance Problems in Distributed Architectures

Andreas Grabner

When moving to a more distributed architecture, you introduce more dependencies and potential for failures to impact services. Common anti-patterns that can arise include making excessive duplicate calls or queries (N+1 patterns), transmitting unnecessary payload data, having services with tight coupling, and inefficient service flows. It is important to understand dependencies between services and automate performance tests and validations as part of continuous integration/deployment pipelines to identify issues and prevent regressions.

Applying AI to Performance Engineering: Shift-Left, Shift-Right, Self-Healing

Andreas Grabner

The document discusses how artificial intelligence can be applied to performance engineering to make it self-healing and self-service. It describes how monitoring needs have evolved from just looking at dashboards and logs to dealing with dynamic cloud environments. It outlines how AI can be used for full-stack monitoring with one agent, automated end-to-end tracing, automated log analytics and change detection. It then discusses how AI can enable shifting work left to break the pipeline earlier, improve mean time to resolution with auto-mitigation, and shift work right with tags, deployments and events to create actionable feedback loops across development, operations and business teams.

Monitoring as a Self-Service in Atlassian DevOps Toolchain

Andreas Grabner

This document discusses how Dynatrace provides monitoring as a self-service through integrations with Atlassian tools, allowing developers to monitor applications throughout the development lifecycle. It explains that Dynatrace automatically monitors the full stack, from the cloud infrastructure to mobile apps. Dynatrace also enables fearless deployments through tracking feature success in JIRA, incident response in chat tools like HipChat, and triaging incidents in JIRA with root cause information from Dynatrace.

Software development... for all? (keynote at ICSOFT'2024)

miso_uam

Our world runs on software. It governs all major aspects of our life. It is an enabler for research and innovation, and is critical for business competitivity. Traditional software engineering techniques have achieved high effectiveness, but still may fall short on delivering software at the accelerated pace and with the increasing quality that future scenarios will require. To attack this issue, some software paradigms raise the automation of software development via higher levels of abstraction through domain-specific languages (e.g., in model-driven engineering) and empowering non-professional developers with the possibility to build their own software (e.g., in low-code development approaches). In a software-demanding world, this is an attractive possibility, and perhaps -- paraphrasing Andy Warhol -- "in the future, everyone will be a developer for 15 minutes". However, to make this possible, methods are required to tweak languages to their context of use (crucial given the diversity of backgrounds and purposes), and the assistance to developers throughout the development process (especially critical for non-professionals). In this keynote talk at ICSOFT'2024 I presented enabling techniques for this vision, supporting the creation of families of domain-specific languages, their adaptation to the usage context; and the augmentation of low-code environments with assistants and recommender systems to guide developers (professional or not) in the development process.
