Serverless Munich Meetup, Juli 2019, Munich: Talk by Mario-Leander Reimer (@LeanderReimer, Principal Software Architect at QAware)
=== Please download slides if blurred! ===
Abstract: Not long ago, the advent of microservice architectures was a big disruption in software engineering: systems were now build, composed and run as autonomous services. But this came at the price of added complexity. Serverless and FaaS seem to be the next disruption, they are the logical evolution in cloud native software development.
Of course, FaaS bringt its own set of challenges, such as cold startup performance, asynchronism and overall throughput. But it does not have to be all that bad. Do you want to know what real fast FaaS looks like? Then fasten your seatbelts when we give Nuclio a try.

Abstract: Good APIs are the center piece of any successful digital product and cloud native application architecture. But for complex systems with many API consumers the proper management of these APIs is of utmost importance. The API gateway pattern is well established to handle and enforce concerns like routing, versioning, rate limiting, access control, diagnosability or service catalogs in a microservice architecture. So this session will have a closer look at the cloud native API gateway ecosystem: Ambassador, Gloo, Kong, Tyc, KrakenD, et.al. But which one of these is the right one to use in your next project? Let's find out. Leander will start off by briefly explaining the API gateway pattern and derive a simple criteria catalog. He will then continue by comparing and showcasing the most promising ones.
Multi-cloud CI/CD with failover powered by K8s, Istio, Helm, and Codefresh Codefresh
**View the full webinar here: https://codefresh.io/multi-cloud-cicd-kubernetes-failover-across-clouds/
Multi-cloud Kubernetes is all about mitigating risk between hosting providers. In this webinar, we'll leverage Kubernetes as our universal cloud API, standup clusters in Google, Amazon, and Azure, setup multi-deploy so our application is in several locations, and demonstrate failover should one cloud fail.
We'll stand up and manage our clusters, then use Istio, Helm, and Codefresh to do a multi-cloud Canary rollout to each cloud.
Come ready to see:
- Continuous Delivery to multiple Kubernetes providers
- Cluster creation on multiple clouds from a single interface
- How to create failover rules
- A practical guide on how to set it up for yourself

Use the right tool and language for the job! Especially in the DevOps tooling area, Go has established itself as a simple, reliable and efficient programming language. In this workshop, we learned about suitable application areas and implementing quite a few tools.
Security still is an underrated non-functional requirement in software engineering, often neglected or even forgotten during the construction and implementation of software systems. If things go wrong the reputation and business of your customers as well as yours might be at stake. Retrofitting security is laborious and expensive, it needs to be considered from day. Sounds hard? Not at all.
This presentation will show that writing secure code and constructing secure systems is not as hard as it may sound. First, we will briefly dissect some well-known security vulnerabilities which were the result of only minor programming errors and we will demonstrate how easy insecurely written Java code can be exploited.
However, writing secure code from day one is just as easy. For this we will present a handful of basic rules and tools every secure developer must know. This session will discuss the secure usage of open source software components in enterprise applications and describe patterns to securely incorporate these libraries. The session will further present basic patterns to construct secure components and system architectures.

Abstract: Until today existing enterprise applications are integrated, tested, and deployed as monoliths. This is very time-consuming and hinders agile business models. Cloud technology promises unlimited scalability, short release cycles, quick deployments and antifragility. But can we evolve these systems into the cloud with reasonable effort? What do we have to change and what are the risks involved? This talk will share the experiences from a real world customer project and present an industrialized approach for the Cloud-native evolution of existing IT landscapes.
Secure your Quarkus applications | DevNation Tech TalkRed Hat Developers
So you have built - in no time - your Quarkus application and it's supersonic subatomic fast. Have you thought about security? Right, usually this is the thing we implement at the end. Even if it's a crucial part of our application, we often ignore it. The good news is that with Quarkus, adding security and identity management is a breeze. Join this 100% live coding session where we explore the different options that Quarkus offers you to secure your applications.
AWS user group meetup container series DXB Dubai
n this session, we will explore the popular workload manager and scheduler Kubernetes. Amazon managed kubernetes service, Elastic Container Service for Kubernetes (Amazon EKS) takes care of the heavy-lifting and lets one focus on managing the containerized workloads. EKS, however, still gives you the flexibility and choice where to run, and how to efficiently run your data-plane that hosts your workloads. In this session, we cover what you need to know to get your application up and running with Kubernetes on AWS. We show how Amazon EKS makes deploying Kubernetes on AWS simple and scalable.
⏳ Agenda
1- Review the general Kubernetes architecture and relate to EKS
2- How to set up and provision your Kubernetes cluster using console and eksctl.
3- Discuss the important abstractions that developers use to map their traditional application into any kubernetes platform.
4- How to deploy software efficiently, while sustaining reliable and scalable applications.
5- Deploy your first microservices on EKS
6- EKS possible development deployment workflow

Abstract: Only a few years ago the move towards microservice architecture was the first big disruption in software engineering: instead of running monoliths, systems were now build, composed and run as autonomous services. But this came at the price of added development and infrastructure complexity. Serverless and FaaS seem to be the next disruption, they are the logical evolution trying to address some of the inherent technology complexity we are currently faced when building cloud native apps.
FaaS frameworks are currently popping up like mushrooms: Knative, Kubeless, OpenFn, Fission, OpenFaas or Open Whisk are just a few to name. But which one of these is safe to pick and use in your next project? Let's find out. This session will start off by briefly explaining the essence of Serverless application architecture. We will then define a criteria catalog for FaaS frameworks and continue by comparing and showcasing the most promising ones.

Abstract:
Vor nicht allzu langer Zeit haben Microservice-Architekturen die Art und Weise, wie wir Softwaresysteme bauen, revolutioniert: Anstatt als Monolithen werden Systeme nun in Form autonomer Services komponiert und ausgeführt.
Serverless und FaaS sind die nächste logische Stufe in dieser Evolution, um die Komplexität in der Entwicklung und im Betrieb solcher Systeme zu reduzieren.
FaaS-Plattformen schießen derzeit wie Pilze aus dem Boden: Knative, OpenFaaS, Fission oder Nuclio sind nur einige Beispiele. Aber welche davon sind bereits geeignet für den Einsatz im nächsten Projekt? Lassen sich damit hybride Architekturen umsetzen oder muss es vollständig Functionless sein? Lasst es uns herausfinden.

== Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! ==
Vor nicht allzu langer Zeit war das Aufkommen von Mikroservice-Architekturen eine große Störung im Software-Engineering: Systeme wurden nun als autonome Dienste gebaut, komponiert und betrieben. Aber das ging nur zum Preis zusätzlichen Komplexität.
Serverless und FaaS scheinen die nächste Störung zu sein. Sie sind eine logische Weiterentwicklung, die der inhärenten technologischen Komplexität Rechnung trägt, mit der wir bei der Entwicklung nativer Cloud-Anwendungen konfrontiert sind.
FaaS-Frameworks und Plattformen schießen derzeit wie Pilze aus dem Boden: Knative, OpenFaaS, Fission oder Nuclio sind nur einige Beispiele.
Aber welches davon ist geeignet für dein nächstes Projekt? Und ist es eine Alles-oder-Nichts-Entscheidung oder auch für hybride Architekturen brauchbar? Lasst es uns herausfinden!
Ziel des Vortrags:
- ein gutes Verständnis der Serverless-Architektur und des FaaS-Programmiermodells
- ein Kriterienkatalog mit wesentlichen Merkmalen zur Auswahl einer geeigneten FaaS-Plattform
- ein Überblick über das Ökosystem der nativen FaaS-Plattform der Cloud
- mehrere Arbeitsvitrinen, die Sie mit nach Hause nehmen und mit sich selbst experimentieren können
Erforderliche Publikumserfahrung:
Grundlegende Programmierkenntnisse und Erfahrungen mit Microservices und nativer Cloud-Technologie sind von Vorteil.

Linux Foundation Collaboration Summit: Hitchhiker's Guide to the CloudMark Hinkle
Imagine it's eight o'clock on a Thursday morning and you awake to see a bulldozer out your window ready to plow over your data center. Normally you may wish to consult the Encyclopedia Galáctica to discern the best course of action but your copy is likely out of date. And while the Hitchhiker's Guide to the Galaxy (HHGTTG) is a wholly remarkable book it doesn't cover the nuances of cloud computing. That's why you need the Hitchhiker's Guide to Cloud Computing (HHGTCC) or at least to attend this talk understand the state of open source cloud computing. Specifically this talk will cover infrastructure-as-a-service, platform-as-a-service and developments in big data and how to more effectively take advantage of these technologies using open source software. Technologies that will be covered in this talk include Apache CloudStack, Chef, CloudFoundry, NoSQL, OpenStack, Puppet and many more.

stackconf 2020 | The path to a Serverless-native era with Kubernetes by Paolo...NETWAYS
Serverless is one of the hottest design patterns in the cloud today, i’ll cover how the Serverless paradigms are changing the way we develop applications and the cloud infrastructures and how to implement Serveless-kind workloads with Kubernetes.
We’ll go through the latest Kubernetes-based serverless technologies, covering the most important aspects including pricing, scalability, observability and best practices
Serverless integration with Knative and Apache Camel on KubernetesClaus Ibsen
This presentation will introduce Knative, an open source project that adds serverless capabilities on top of Kubernetes, and present Camel K, a lightweight platform that brings Apache Camel integrations in the serverless world. Camel K allows running Camel routes on top of any Kubernetes cluster, leveraging Knative serverless capabilities such as “scaling to zero”.
We will demo how Camel K can connect cloud services or enterprise applications using its 250+ components and how it can intelligently route events within the Knative environment via enterprise integration patterns (EIP).
Target Group: Developers, architects and other technical people - a basic understanding of Kubernetes is an advantage

GIDS 2019: Developing Apps with Containers, Functions and Cloud ServicesPatrick Chanezon
Cloud native applications are increasingly composed of containers, serverless functions responding to events and managed cloud services. What is the best workflow and set of tools to provide a rapid, iterative development experience and to package applications using these three components?
This hand-on talk will compare and contrast several sets of tools and their associated workflows:
Using Docker Desktop, with its local Docker engine and Kubernetes cluster, with open source tools such as the Virtual Kubelet, or the Gloo hybrid app gateway, to build the most productive development inner-loop for these type of applications
OpenFaaS, Fn, or Nuclio open source serverless framework to run functions in containers locally
Telepresence to run a container locally, connected to a remote cluster
Helm and Draft
Knative
The talk will also cover how you can use the Cloud Native Application Bundle (CNAB) format and tools to package your applications and share them using a container registry.
Mit ChatGPT Dinosaurier besiegen - Möglichkeiten und Grenzen von LLM für die ...QAware GmbH
Generative AI for Developers, 27.05.2024, Bonn (Martin Binder, Lead IT Consultant bei QAware)
Die kritische Infrastruktur wird nach wie vor von Dinosauriersystemen aus dem letzten Jahrtausend getragen. Die Ablösung dieser Altsysteme ist ein drängendes Problem der Digitalisierung in Deutschland. In meinem Projekt musste ich in wenigen Wochen ein 30 Jahre altes System auf Basis von IBM iSeries (AS/400) mit RPG-Code analysieren. Überraschenderweise kannte ChatGPT die RGP-Referenz von IBM. Mithilfe von ChatGPT konnte ich mich schnell einarbeiten und so ein brauchbares Arbeitsverständnis des Systems erreichen. Aber wo Licht ist, ist auch Schatten: ChatGPT hat kein Kontextverständnis, ist unvollständig und neigt zu Fehlschlüssen. Als Vorgeschmack hier der Powermove: ChatGPT nach jeder Antwort grundsätzlich danach fragen, was es falsch gemacht hat. Du wirst überrascht sein!

== Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! ==
Abstract:
Elasticity and unlimited scalability are the holy grail for any cloud-native application. Now you might think: “That’s easy!!! I just run my containers on a Kubernetes cluster and I am done.” But is it really that simple?
Turns out it’s not! Your application as well as your cloud infrastructure and K8s cluster need to address and support these non-functional requirements.
This session will have a detailed and also practical look at the different ways of autoscaling in Kubernetes. We will give an overview of the technical foundations and prerequisites, and then showcase several frameworks and technologies that can be used to flexibly autoscale your cluster and your cloud-native workloads.
Make Agile Great - PM-Erfahrungen aus zwei virtuellen internationalen SAFe-Pr...QAware GmbH
GPM Regionalgruppe Chemnitz (Patrick Albert)
Wegen ihres Umfangs und Komplexität sind größere SAFe-Programme bereits in Präsenz hinsichtlich ihres Managements und ihrer Steuerung anspruchsvoll. Aufgrund von COVID19 jedoch war eine Verlegung in den virtuellen Raum im beschriebenen Praxisfall unausweichlich. Das Management hatte hierbei sicherzustellen, dass die Programmziele trotz des verminderten Kontaktes allen beteiligten Teams dauerhaft klar und präsent sind und dass die in den Teams umgesetzten Funktionen außerdem den genannten Programmzielen dienen.
Besonders wichtig ist dieses Alignment im Rahmen der regelmäßigen PI-Plannings, in welchen alle Teams gleichzeitig die jeweils kommenden Iterationen planen und dabei auch teamübergreifende Abhängigkeiten zuverlässig berücksichtigen müssen.
Es werden Erfolgsfaktoren für den virtuellen Einsatz von SAFe herausgearbeitet und beleuchtet.
Fully-managed Cloud-native Databases: The path to indefinite scale @ CNN MainzQAware GmbH
When it comes to the question: "Where do we actually store our application data?", we are spoilt for choice, especially when it comes to the major cloud providers.
The simple and often completely valid answer is still the classic relational database! It is very suitable for many areas of application, as the technology is tried and tested and can cover a very broad spectrum. It is therefore not surprising that all major cloud providers offer this as a "managed service".
For some years now, however, there have also been so-called cloud-native databases that have been specially developed for the requirements of the cloud. The big promise: "Infinite scalability"
In a large customer project, we have been using such a database productively for over 4 years with Azure CosmosDB. The presentation will deal with the following questions, among others
What does "upscalability" mean in practice ?
What do you have to pay attention to when designing?
What are the actual limits?
What other special features do I get?
When do I need a cloud-native database?
But that's not all! We also look beyond Azure to the other two major cloud providers: AWS and Google Cloud. With DynamoDB and Datastore/Firestore, they have similar products on offer.
Down the Ivory Tower towards Agile ArchitectureQAware GmbH
iSAQB Software Architecture Gathering – Digital 2023, November 2023
Architecture for agile projects must be defined and described differently, as well as continuously developed and evolved. Not all decisions are made at once, nor are they all known right from the start of the project. This sessions presents various useful and lightweight methods, tools and team topologies that can be applied in (large) agile projects to avoid uncontrolled growth and architectural erosion but without acting from the ivory tower and thus suffocating team autonomy.
"Mixed" Scrum-Teams – Die richtige Mischung macht's!QAware GmbH
IT-Tage 2023, Frankfurt am Main (Patrick Albert)
Die Rollen und insbesondere deren Zuständigkeiten sind in Scrum recht klar geregelt: Der Product Owner sorgt für das "Was", der Scrum Master für das "Wie" und die Developer für die eigentliche Umsetzung. Solange es sich dabei um ein internes Projekt mit einem komplett internen Team handelt, sind damit bereits die zentralen Fragen beantwortet. Ein wenig differenzierter zu betrachten sind allerdings Teams mit mehreren Parteien wie etwa beim Einsatz von Dienstleistern. Muss etwa zwingend der Kunde den Product Owner stellen oder kann dieser auch auf der Seite des Dienstleisters stehen? Falls alle Developer vom gleichen Dienstleister bereitgestellt werden, würde diese Konstellation sicherlich einige Kommunikationswege verkürzen. Allerdings hat ein Product Owner auf der Seite eines Dienstleisters sicher nicht die gleichen Verbindungen zu den Stakeholdern (Nutzer, Geldgeber, ...) des Produkts wie ein interner Product Owner – wie also könnte er ihre Anforderungen dann gut vor dem Team vertreten? Ähnliche Fragen stellen sich auch für den Scrum Master und das Development-Team. In den meisten Fällen gibt es für verschiedene Konstellationen jeweils Vor- und Nachteile – und zwar sowohl für den Kunden als auch für den Dienstleister. Wichtig bei der Entscheidung für eine dieser Konstellationen ist außerdem die Art des Projekts, der Kreis der Stakeholder, das zur Verfügung stehende Budget, der Zeitrahmen und noch einiges mehr.
Dieser Vortrag beleuchtet verschiedene dieser Varianten und zeigt Vorteile, Nachteile und Risiken auf.
Make Developers Fly: Principles for Platform EngineeringQAware GmbH
Make Developers Fly – Helping developers to build better applications
Cloud Native Night, Mainz, November 2023, Alex Krause
Platform Engineering is the next stage of DevOps and accelerates software developers even more to build applications faster and bring products rapidly to the customers. In this meetup, we show you the key principles of platform engineering, as we experienced them in our projects, and additionally show you a better way to manage your internal software platforms.
PRINCIPLES FOR PLATFORM ENGINEERING, Alex Krause
How do we help our developers to fly instead of crashing miserablely? The answer is Platform Engineering, a discipline for building internal developer platforms (IDPs) to simplify software delivery for product teams. In this talk, you'll learn how Platform Engineering evolved from the DevOps movement and what principles and best practices make for a good implementation. Finally, we'll take a look at reference architectures that can support your platform.
Der Tod der Testpyramide? – Frontend-Testing mit PlaywrightQAware GmbH
Codineers Rosenheim Meetup, 2. November 2023 (Dominik Haas, QAware)
Wer kennt es nicht: Langsame, instabile und wartungsintensive Tests von Frontends und die Schmerzen damit.
Aber in den letzten Jahren und Monaten hat sich hier viel getan und Playwright ist der vielversprechende neue Stern der Web-Automatisierung.
Ich werde in meinem Talk über das Testen von Frontends sprechen und speziell auf Playwright als spannendes Werkzeug eingehen.
Neben der praktischen Einführung möchte ich auch mit Euch über Best Practices sprechen und einen Versuch wagen die Testpyramide zu töten (oder sie zumindest etwas zu beschädigen).
Sie kennen doch bestimmt das "Gesetz des Instruments": Wer als Werkzeug nur ein modernes Frontend-Framework hat, löst jedes Problem mit einer Single Page-Applikation. So oder so ähnlich, nur halt mit Hammer und Nagel lautet es, beschreibt jedoch ganz gut die aktuelle Situation der JavaScript-Welt. Auf nahezu jede Anforderung wird mit einer aufgeblähten, clientseitig gerenderten SPA geantwortet. Doch ist es schön langsam an der Zeit, dass wir uns fragen sollten: Ist das wirklich alles? Und die Antwort lautet ziemlich sicher "Nein". Doch genau diesem Thema widmen wir uns und werfen einen Blick auf die Alternativen und da gibt es viele.
Im React-Ökosystem findet aktuell ein kleiner Umbruch statt. Mit Server Side Rendering, Static Site Generation, Server Components und Frameworks wie Next verschiebt sich ein Teil der Arbeit in Richtung Server. Dieser Trend ist auch bei Vue, Svelte und Angular zu beobachten. Und genau das ist es, was die sogenannten Meta-Frameworks ausmacht. Uns als EntwicklerInnen gibt das mehr Flexibilität, um auf Anforderungen reagieren zu können. Sie müssen nicht mehr den kompletten Quellcode zum Client übertragen, haben bessere Caching-Möglichkeiten und auch die Suchmaschinen sind Ihnen dankbar.
Dieser Vortrag gibt Ihnen einen Überblick über die wichtigsten Features von Meta-Frameworks und wo und vor allem wie sie gewinnbringend eingesetzt werden können.

== Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! ==
Der Vortrag „Migration von stark regulierten Anwendungen in die Cloud: Dem Teufel die Seele verkaufen oder Himmel auf Erden?“ erkundet das wachsende Bedürfnis und die Herausforderungen, medizinische Anwendungen in die Cloud zu migrieren.
Bei den entsprechenden Anwendungen stellt laut einer Umfrage der Datenschutz für 82% der Anwendungen die größte Herausforderung dar, um den Schritt in die Cloud zu machen. Trotzdem wächst der Druck, diesen Schritt zu vollziehen, aufgrund des Innovations- und Digitalisierungsbedarfs, der durch gesetzliche Initiativen wie das Krankenhaus-Zukunftsgesetz, gestiegene Patientenerwartungen und den immer klareren medizinischen Impact der Digitalisierung angetrieben wird.
Die zentrale Frage, die in diesem Vortrag erörtert wird, ist, wie man hochregulierte Anwendungen schrittweise in die Cloud migrieren kann. Hierzu werden wir einen Ansatz vorstellen und anhand von exemplarischen Anwendungen demonstrieren, wie eine solche Migration erfolgreich durchgeführt werden kann. Abschließend fassen wir den Vortrag mit fünf leitenden Prinzipien zusammen, die bei der Migration von stark regulierten Anwendungen in die Cloud beachtet werden sollten. Diese Prinzipien bieten einen nützlichen Leitfaden für Unternehmen und Institutionen, die den Umzug ihrer Anwendungen in die Cloud erwägen, und sollen dazu beitragen, die Herausforderungen der Cloud-Migration in diesem hochregulierten Bereich erfolgreich zu bewältigen.
Aus blau wird grün! Ansätze und Technologien für nachhaltige Kubernetes-Cluster QAware GmbH
SAA 2023 | Software Architecture Alliance, September 2023, München, Mario-Leander Reimer (@LeanderReimer, CTO bei QAware)
== Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! ==
Die Cloud hat bereits heute einen größeren CO2-Fußabdruck als die Luftfahrtindustrie, mit steigender Digitalisierung und Cloudifizierung wird sich dieser Trend fortsetzen, wenn wir nichts dagegen unternehmen. Viele Kubernetes-basierte Installationen sind gemessen am eigentlich benötigten Ressourcen Bedarf stark überdimensioniert und tragen so unnötig zur globalen Erwärmung bei. Wie sieht die Energiebilanz Ihres Clusters und Workloads aus?
In diesem Vortrag zeigen wir Ansätze und Technologien, die dabei helfen K8s-Cluster grün(er) zu machen. Zunächst braucht es Transparenz: Wie sieht die Energiebilanz des Clusters und seiner Workloads aus? Erst danach lassen sich diese gezielt auf ihre Energiesparsamkeit hin optimieren. Und das ist gar nicht so schwer, also packen wir es an!

Der Traum von den unendlichen Weiten der Daten ist schnell ausgeträumt, wenn wir unsere APIs nicht im Griff haben. Dabei ist es egal, ob wir uns APIs zwischen unseren Services, zwischen Frontend und Backend oder zu Fremdsystemen anschauen - APIs sind ein fundamentaler Bestandteil unserer Softwarearchitektur und ohne Testautomatisierung geht gar nichts.
Schlecht geschriebene Integrationstests mit selbst erfundenen Testfällen für unsere APIs können richtig nerven: Wir rufen die APIs auf und hoffen, dass genau das zurückkommt, was wir erwarten.
Das geht auch anders: Wir werfen einen Blick auf andere Testansätze, bewerten, welche Aspekte diese jeweils testen und schauen zum Beispiel auf:
• Contract Based Testing
• Black Box Testing der OpenAPI Specs
• Trace-basiertes Testing

== Dokument bitte herunterladen, falls unscharf! Please download slides if blurred! ==
Continuous Delivery ist allgegenwärtig. Wirklich? Viele Teams straucheln immer noch dabei, regelmäßig gut getestete und vor allem sichere Software auszuliefern. Immer mit der gleichen, guten alten Ausrede: die nicht-funktionalen Tests seien zu aufwändig und zu teuer umzusetzen. Doch genau das Gegenteil ist der Fall!
In diesem Vortrag gehen wir kurz auf die aktuellen Bedrohungen und die Bedeutung früher und regelmäßiger Sicherheitstests von APIs ein. Anschließend zeigen wir, wie einfach es ist, diese Tests kontinuierlich und asynchron mit OWASP ZAP und Testkube gegen REST- und GraphQL-APIs direkt auf einem Kubernetes-Cluster auszuführen; immer dann wenn sich die API und der Service ändern.
Service Mesh Pain & Gain. Experiences from a client project.QAware GmbH
Cloud Native Night, Mainz, September 2023, Markus Zimmermann
=== Please download slides if blurred! ===
The topic of service mesh is still present at every major DevOps conference and is the subject of controversial discussions.
A service mesh comes with the promise of implementing cross-functional requirements of microservices such as observability or secure communication without changes within the services. The operational effort and the integration of the services within the service mesh should also be problem-free.
But do the common service mesh implementations keep these promises? In a client project we have gained experience with Linkerd and can say: we did not achieve the benefits without pain. We want to share these experiences and what you can take away for your next project!

Blue turns green! Approaches and technologies for sustainable K8s clusters.QAware GmbH
Kubernetes Community Days Munich 2023, Juli 2023, Mario-Leander Reimer
The cloud already has a larger CO2 footprint than the worldwide aviation industry. With increasing digitalization and cloudification this trend will continue if we don't do anything about it. Many Kubernetes installations are greatly oversized in terms of the resources actually required and thus contribute unnecessarily to global warming. What is the energy balance of your cluster and its workloads?
In this session we will discuss approaches and technologies that help to make K8s clusters green(er). First of all, transparency is needed: what is the energy balance of the cluster and its workloads? Only then we can start to optimize for better energy efficiency. And it's not that difficult, so let's get started!

Understanding Globus Data Transfers with NetSageGlobus
NetSage is an open privacy-aware network measurement, analysis, and visualization service designed to help end-users visualize and reason about large data transfers. NetSage traditionally has used a combination of passive measurements, including SNMP and flow data, as well as active measurements, mainly perfSONAR, to provide longitudinal network performance data visualization. It has been deployed by dozens of networks world wide, and is supported domestically by the Engagement and Performance Operations Center (EPOC), NSF #2328479. We have recently expanded the NetSage data sources to include logs for Globus data transfers, following the same privacy-preserving approach as for Flow data. Using the logs for the Texas Advanced Computing Center (TACC) as an example, this talk will walk through several different example use cases that NetSage can answer, including: Who is using Globus to share data with my institution, and what kind of performance are they able to achieve? How many transfers has Globus supported for us? Which sites are we sharing the most data with, and how is that changing over time? How is my site using Globus to move data internally, and what kind of performance do we see for those transfers? What percentage of data transfers at my institution used Globus, and how did the overall data transfer performance compare to the Globus users?

Why React Native as a Strategic Advantage for Startup Innovation.pdfayushiqss
Do you know that React Native is being increasingly adopted by startups as well as big companies in the mobile app development industry? Big names like Facebook, Instagram, and Pinterest have already integrated this robust open-source framework.
In fact, according to a report by Statista, the number of React Native developers has been steadily increasing over the years, reaching an estimated 1.9 million by the end of 2024. This means that the demand for this framework in the job market has been growing making it a valuable skill.
But what makes React Native so popular for mobile application development? It offers excellent cross-platform capabilities among other benefits. This way, with React Native, developers can write code once and run it on both iOS and Android devices thus saving time and resources leading to shorter development cycles hence faster time-to-market for your app.
Let’s take the example of a startup, which wanted to release their app on both iOS and Android at once. Through the use of React Native they managed to create an app and bring it into the market within a very short period. This helped them gain an advantage over their competitors because they had access to a large user base who were able to generate revenue quickly for them.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

8. USE CASE 1
HYBRID ARCHITECTURES
> Combine Microservice Architecture
with EDA
> Leverage Function services for
Event-driven use cases
> Reduce resource consumption and
costs via Scale 2 Zero
> Integrate into existing Enterprise
PaaS environment
9. USE CASE 2
EDGE AND FOG COMPUTING
> Research project: evaluate usage of
FaaS for low power devices
> Support for lightweight schedulers
like Docker Swarm
> Support for compiled language
runtimes like Go
10. MY CRITERIA TO CHOOSE THE IDEAL FAAS PLATFORM
> Open Source - no initial $$$ and no vendor lock-in please
> Maturity - good and active community, little issues, frequent releases
> Use Cases - general purpose, enterprise, big data, AI, edge computing
> Approachable - quick start and sufficient documentation
> Language Runtimes - please more than JavaScript!
> Developer Friendly - tools & frameworks, local runtime, testing, IDE support
> Operability - easy setup, supported platforms, technology footprint
> Integration - supported triggers, infrastructure, plugins, standards
> Performance - good cold startup performance and throughput
