Cloud Native Engineering using Kubernetes

In the fast-evolving world of Cloud Native, engineers are constantly looking for new technologies and tools that solve today’s challenges. Finding your missing piece of open-source software feels great. But nothing beats the feeling of creating and releasing your selfmade masterpiece.

Luuk can tell you all about it. He is the lead developer for cnfuzz: a project written in Golang that automates fuzzing web APIs deployed in Kubernetes clusters. By tracking hashes of all container images, (re)deployed web API versions will be fuzzed – to detect potential security and stability issues. Using this project and various demos Luuk will show you:

  • why it’s great to build software with and for Ku​​bernetes;
  • what’s an easy way to start with cloud native development;
  • how the k8s API works;
  • which tools you can use to debug (and develop);
  • and of course, the ins and outs of cnfuzz!

Speaker

Luuk van den Maagdenberg started his career as graduation intern at the Sue Incubator. His research on “How can a web API within a Kubernetes cluster be automatically checked on security and stability issues through fuzzing?” resulted in promising outcomes. That’s why Sue invited Luuk after his study Cyber Security & Software Engineering to put his research into practice. May 5 will be the first time he will tell about cnfuzz, but it will definitely not the last time you will hear about this project!

Besides cnfuzz, Luuk works on a NXP-project and he will start engineering for De Volksbank soon. With his refreshing ideas and in-depth knowledge of modern technologies such as Golang, Kubernetes, AWS, Data Lake and CI/CD, Luuk definitely belongs to the next generation of promising cloud native engineers!

OpenTelemetry: inzicht in de hele tech stack!

OpenTelemetry: inzicht in de hele tech stack!

OpenTelemetry: inzicht in de hele tech stack!

De wereld wordt steeds meer cloud native. Deze verandering heeft impact op alle lagen van de technologiestack. De complexiteit neemt toe en wordt steeds verder geabstraheerd. Daarmee wordt het lastiger om overzicht en grip op de hele stack te houden. Slow is the new down en het vinden van de oorzaak van een verstoring is steeds meer werk voor specialisten.

Gelukkig komen we bij de modernisatie van IT-systemen steeds vaker OpenTelemetry tegen. Deze open standaard versnelt de modernisering van monitoring naar observability. Na deze sessie weet je waarom OpenTelemetry zo’n belangrijke stap is. Je wordt meegenomen in de historie en de huidige staat van het project. Daarnaast zie je met eigen ogen hoe het nu al toe te passen is, zodat je meer inzicht krijgt in de hele technologiestack.

Spreker

Erwin Vrolijk helpt je effectiever werken op basis van data. Hij gebruikte al containertechnologie voordat Docker uitgevonden was, ontwierp en bouwde netwerken op de Noordzee, maakte het beheer van Private Cloud een stuk makkelijk door efficiënte monitoring en was architect van het Monitoring and Analytics landschap van ASML. Nu is hij Senior Solution Engineer bij Splunk. Verder houdt hij van een goeie espresso en nerden met hardware, zowel met zijn Raspberry Pi als een Range Rover V8.

ElasticSearch: Best Practices and Common Pitfalls

ElasticSearch: Best Practices and Common Pitfalls

ElasticSearch Best Practices and Commen Pitfalls

Do you work with an Elasticsearch cluster consisting of more than one machine? If so, then it is very important to keep the cluster healthy and to prevent data loss. This may seem obvious, but most teams face at least two challenges. First, a developer needs to design efficient data mapping and performant queries. Second, an operator needs to design a resilient cluster. In other words: in a DevOps environment both developers and operators need to know the basics in data mapping and cluster design.

In the era of Elastic Cloud some aspects of these operations are managed by Elastic itself. However, in practice organizations experience that other aspects may become even more difficult than with a self-managed cluster!

On Thursday March 3, Thijs van der Gugten will discuss and demo:

  • common scenarios and challenges in Elasticsearch operations;
  • best practices, based on hands-on experience;
  • some ways to break an Elasticsearch cluster, and how to avoid this 😉

Speaker

After completing a degree in mathematics, Thijs van der Gugten accidentally started working in IT, and stayed for the challenges of building resilient infrastructures. To observe a complex infrastructure, he prefers building and watching dashboards over grepping through log files. Here is where Elastic came in.

At Sue, Thijs has been working with Elastic for several years now. He helped various companies with one thing in common: analyzing complex data (like TextKernel and vidaXL for example). Previously, Thijs gave a workshop at SUSECON, he hosted several trainings at Sue and now he cannot wait to share his elastixperiences with you!

The OneWelcome journey to a cloud-native platform

The OneWelcome journey to a cloud-native platform

Abstract

Only a few years ago OneWelcome (Onegini) was delivering software for on premises installations. Stein Wellberg and Bart van der Schans will present why and how they made the decision to move to cloud-only and what that meant for their company. How did this impact the engineering practices? What changed in how to architect, build and deploy our software? How did they evolve over time?

You will get an in depth look at the current platform and how they leverage AWS services, Terraform, Kubernetes, Prometheus, Spring Boot, Helm, Skaffold, CI/CD, GitOps tools and Serverless to build and run their cloud environment. What did OneWelcome learn (the hard way) and where do they want to go next?
