stackconf online 2021 | The Importance of Visuals in Teaching Code and Reducing Bias

This entry is part 7 of 9 in the series stackconf online 2021

This year’s stackconf is over and was a big success. The three-day conference this summer was all about open source infrastructures where trendsetting concepts, state-of-the-art technical expertise, top-level discussions and new perspectives have shaped the event.

Besides our 30 amazing experts sessions we were also excited about the large amount of participants from all over the world. Our audience included renowned infrastructure spezialists, industry leaders, experienced administrators and IT architects as well as a wild bunch of open source community enthusiasts.

For all of you who couldn’t join the Open Source Infrastructure Conference I’ve something awesome today. Can you imagine to communicate the code concepts with images? Me neither. Tadeh Hakopian’s talk shows you how using geometry and modeling can acclimate novices to coding concepts using visual-spatial examples reinforced by coding concepts applicable anywhere. Enjoy!

 

 

stackconf 2022 will take place in Berlin. We are already looking forward to meeting you all again in person next year. The exact date of the event will be announced soon.

If you want to learn more about infrastructure solutions in advance always keep in mind that there’s our archive where you can find all slides and videos of every stackconf speaker.

Stay tuned!

For all of you who couldn’t join the Open Source Infrastructure Conference I’ve something awesome today. Nicolas Fränkel was one of our speakers and talked about “Pragmatic App Migration to the Cloud: Quarkus, Kotlin, Hazelcast and GraalVM in action”. In his talk, he created a simple URL shortener with a “standard” stack: Kotlin, JAX-RS and Hazelcast. With the help of Quarkus and GraalVM, he turned this application into a native executable with all Cloud/Container related work has been moved to build the process. Doesn’t that sound exciting? Enjoy his lecture!

stackconf online 2021 | Why you should take care of infrastructure drift

This entry is part [0] of 9 in the series stackconf online 2021

stackconf online 2021 is over and was a full success. It was all about open source infrastructure solutions in the spectrum of continuous integration, container, hybrid and cloud technologies. We’re still excited about all of our experts sessions and the large number of participants who joined us from all over the world. In the following you get an insight about one of our talks.

 

Stephane Jourdan, co-author of Infrastructure-as-Code Cookbook and co-founder of Driftctl lectures us in the talk “Why you should take care of infrastructure drift” about infrastructure drift, why it’s causing issues and how to avoid and mitigate it.

The talk starts off by looking for a definition for infrastructure drift, asking users and customers for their experiences. Infrastructure drift happens when the reality and the expectations don’t match is the definition given. This is supplemented by a technical explanation: the configuration provided by our management tools doesn’t match the configuration on our actual machines. For varying reasons, whatever configuration we have running in our cloud infrastructure, in our AWS machines, differs from the configuration we have provided in Terraform. That difference is infrastructure drift.

Infrastructure drift simply explained

Infrastructure drift: A simple overview

It is caused by unmanaged resources in the cloud infrastructure, be it manual inputs directly into the machines, dynamic updates, different teams working with different software, making changes to the configuration in the cloud. These changes are not being supervised by our configuration management tool, and if not checked regularly for infrastructure drift, these differences can stay there for weeks, months even. Many companies are adopting automation when using and providing cloud infrastructure and it is very easy to overlook infrastructure drift, posing a considerable security threat. Driftctl helps us by checking for these differences and giving us a report about the quantity of infrastructure drift.

Then Stephane shares user stories with us. We hear about using Driftctl to check Terraform: users making manual inputs, changing access rules and firewall configurations in AWS creating rules which are not being covered by Terraform. These issues were caused by varying authorized people making changes directly in AWS web UI, and persisted in each case with unacceptable duration. The usage of Driftctl is being presented to us in live demos – the user inputs of the stories were being replicated and Stephane demonstrates how Driftctl checks these differences and notifies the user by giving a percentage calculated, informing them about the serverity of the infrastructure drift in their environments.

Driftctl scans Terraform and finds two rouge instructions

To finish up his talk, Stephane shows us more usages of Driftctl: scanning JSON Output for differences, using the .driftignore file to ignore occurrences of infrastructure drift, scanning with filters to focus on specific  areas of the AWS accounts, and using Driftctl in CI setups, where a Docker container is being provided for easy integration in various CI systems.

 

stackconf 2022 will take place in Berlin. The final date will be announced soon. If you want to learn more about infrastructure solutions in advance you have the possibility to take look at our archive where you can find all slides and videos from this year’s stackconf.

Stay tuned!

For all of you who couldn’t join the Open Source Infrastructure Conference I’ve something awesome today. Have you ever heard of „Data Driven Security“? Peter Elmer outlines in the following video why this is more effective than traditional research methodologies, as it combines data, human experience and logic made by machines to define the verdict. Enjoy!
