Developers arriving at the Serverless scene usually find it hard to use the previous methodologies and tools they are used to in this new arena. Why? Because you can’t run Serverless locally. Up until now, a developer could spin a container or install PostgreSQL or NGNIX on their machine and start playing. The cycle of code → build → test was reasonably fast, but now it changed, building and testing cannot run locally, they have to run in the cloud which causes developers to lose productivity.
How do we change it? How do we keep the same productivity levels while enjoying the benefits of Serverless.
The following session will cover:
Reasons for a slow development cycle in Serverless environments
Tips and tricks for speeding up the development flow

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

ENT317 Dynamic Infrastructure? Migrating? Adventures in Keeping Your Applicat...Amazon Web Services
"Keeping an application running at scale can be a daunting task. When do you need to add more capacity? Larger databases? Additional servers? These questions get harder as the complexity of your application grows. Cloud-based dynamic infrastructures can help you keep your application running with high availability, even during times of extreme scaling. We will discuss some of the best practices we’ve learned working with New Relic customers on how you can manage your applications running at scale, and how technologies such as dynamic infrastructure can help you with this challenge. Joining us on stage will be Appboy, the global leader in lifecycle engagement technology, to discuss their experiences with dynamic infrastructure and the cloud and how it has impacted their ability to scale.
This session is brought to you by AWS Summit New York City sponsor, New Relic."
ENT317 Migrating with Morningstar: The Path To Dynamic CloudAmazon Web Services
Keeping an application running at scale in the cloud is fundamentally different than keeping your applications running in your own data centers. Cloud technologies are different, the way you scale is different, the way you troubleshoot is different, and the monitoring you need is different. From static compute to dynamic autoscaling to serverless services and microservices, combined with the demands of creating new digital businesses, cloud services provide new opportunities and challenges. In this session, New Relic’s Lee Atchison and Morningstar, a global investment research company, will discuss the differences in cloud technologies impact on monitoring and architectural strategies when migrating and scaling applications on AWS.

DevOps: Cultural and Tooling Tips Around the World
DevOps! One of the most abused terms in the software industry over the last few years. One of the reasons for this is that the term can mean something totally different, depending on what your role is, and what kind of business you are in. Yet, it is a very real practice with solid benefits that allow companies to build better quality software faster, and with lower cost and risk.
In this 30-minute “secret sauce” session, Andreas Grabner, DevOps Activist at Dynatrace, shares customer learnings and best practices from DevOps adopters around the world. You’ll gain insights from questions like:
• What does DevOps really mean for developers, testers and operators?
• How do companies like Facebook deploy twice a day without big issues?
• How does DevOps work in industries like finance, government, and healthcare where tight regulations exist?
• Is Dev responsible for Ops? Or only if you are working in a Cloud environment?
• What is different and unique as we move from old-fashioned on-prem software to hybrid and Cloud apps?
• Why is talking to people the forgotten DevOps tool?
JavaOne - Performance Focused DevOps to Improve Cont DeliveryAndreas 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

DevОps is usually viewed from a traditional perspective of a collaboration of Dev, Ops, and QA, driven by the change in Culture, People, and Process. But how do you know where you stand and where to move? As in almost any field, data and metrics give you the gauges and instruments. In this talk, we’ll talk about the key measurements for the DevOps transformation process and provide you with 3 metrics you can start measuring tomorrow.
We've learned a lot through doing DevOps: Every commit is automatically integrated, tested, and deployed to a staging environment. And then it only takes one push of a button and the release goes live...
Unfortunately, it's not as simple anymore when operating mobile applications: How can you quickly update your mobile software when the app store provider wants to test your software first for a few days? How can you update your configuration when your app can run offline? And how do you track down errors when the data is distributed to millions of mobile clients? Those were just some of the challenges we encountered during the operation of mobile games with millions of daily users. In this talk we will talk about the solutions we have found to address them.
KCD Munich - Cloud Native Platform Dilemma - Turning it into an OpportunityAndreas 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 ProductionAndreas 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 DeploymentsAndreas 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 KeptnAndreas 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.
Release Readiness Validation with Keptn for Austrian Online Banking SoftwareAndreas Grabner
Marco and Andreas work at Raiffeisen Software who provides banking software for many Austrian financial institutions. In this session they show us how Keptn is used to automate the validation of key SLOs as part of their release process.
Adding Security to your SLO-based Release Validation with KeptnAndreas Grabner
This talk was given at DevSecOps Days Boston and DevOps & Security Meetup Vienna in 2021
Automatic Release Validation, aka Quality Gates, is not a new concept but often only covers functional or performance metrics. Keptn’s open SLO-based evaluation allows DevSecOps to have their favorite security tool report SLOs such as number of detected vulnerabilities as part of delivery automation
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.

Applying AI to Performance Engineering: Shift-Left, Shift-Right, Self-HealingAndreas Grabner
AI might be an overused marketing buzzword but the advances in fullstack monitoring and data analytics are clearly an advantage for the modern performance engineer.
In this presentation given at different events, e.g: CMG Image, Neotys PAC, ... I discuss how monitoring has evolved and how we can leverage AI to implement concepts such as Shift-Left, Shift-Right and Self-Healing
Monitoring as a Self-Service in Atlassian DevOps ToolchainAndreas Grabner
As devs, testers and ops we must deal with monitoring data when analyzing test results, debugging problems or reporting on usage. But why stepping out of our Atlassian Tool Comfort Zone to get this data? We found new use cases on how to fully integrate monitoring as a self-service into Jira, Hipchat, Bamboo, Bitbucket & Confluence. This saves time in learning yet another tool and gives you the data when and where you need it: in your most favorite Atlassian Tool. Key Use Cases we discuss: Continuous Performance Analysis in Jira, Shift-Left in Bamboo / Bitbucket, ChatOps in Hipchat.
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 DeploysAndreas 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.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:
Your campaign sent to target colleagues for approval
If the “Approve” button is clicked, a Jira/Zendesk ticket is created for the marketing design team
But—if the “Reject” button is pushed, colleagues will be alerted via Slack message
Join us to learn more about this new, human-in-the-loop capability, brought to you by Integration Service connectors.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Editor's Notes
MEASURE!!
Who knows what that is?
It’s the Fifa World Cup Trophy
Teams are currently competing in the qualifications to compete in Brazil 2014
This is “my” austrian national team soccer team.
Their GOAL is to qualify for Brazil 2014. After the many failed attempts in the past we hired a new coach who’s goal is to form a new team that PERFORMs good enough to qualify
In order to get there the team competed in many test games. Which gaves them a lot of confidence because they played against teams that were “easier” to beat.
At the end of these tests we even started in the qualification with some wins against teams that we were expecting to win
So – at the end of these “test and easy qualification games” we thought: “ALL GOOD – THE ROAD IS OPEN FOR 2014 – NOT ONLY WILL WE QUALIFY BUT WE ALSO BELIEVE WE HAVE SUCH A STRONG TEAM THAT WILL ALSO DO WELL AT THE WORLDCUP”
Then reality kicked in when we had our first “real competitor” – it was the first qualification against a team whos quality level is at a level that we have to expect at the world cup.
The competing team was Germany – and – based on these images you can see how the game went
The coach is responsible to watch the game and see how things are going.
Like in other sports – soccer has a couple of Key Performance Indicators such as Ball Possession, Fouls and the actual score
The first 5 minutes actually didn’t look too bad
After the first 5 minutes the game changes – with germany taking over the game in their typical way. The KPIs make this very clear
The coach is responsible to react based on these values and how the game wents
The coach should use more data for detailed analysis on what is going wrong in the game
One of his options is to substitute players – or even change tactics
Does this succeed based on the KPIs that we have seen before?
Well – not always. Just replacing players – putting some in that are faster in chasing the ball doesn’t always help
