Exploring Axon

In this episode, Sara spoke with Arjan Noordhoek, a software architect, and consultant. They talked about Arjan’s new event modeling tool, Model My Code. He explained how to use it and where to get it. He discussed why it is important to, as he puts it, make design center-stage again, as well as the importance of outcome-driven discovery sessions. Arjan’s tool will be available as a public beta next week.   You can find out more about Arjan's company here.

Sara spoke with a colleague, Mitchell Herrijgers, one of Axon Framework's engineers and one of AxonIQ's Solutions Architects. Mitchell has been leading a project for a tool internally called "Inspector Axon." This tool helps developers monitor various things within their Axon Framework-based application and gauge metrics, find out about various event processors, and much more. The name will most likely change once it is publicly available, but for now, we are referring to it as "Inspector Axon." Mitchell also worked on a different project last year: the IntelliJ plugin for Axon Framework. He also briefly talked about that at the end of the session.  If you are interested in becoming one of our private beta testers for Inspector Axon, please watch our social media for an announcement, or you can reach us through our website.    Connect with Mitchell on LinkedIn.  Connect with Sara on LinkedIn and Twitter.    For more information about us, visit axoniq.io  

Sara spoke with Allard Buijze, the CTO of AxonIQ live, about the various types of nodes currently used in Axon Server and the benefits of each. He then explained the difference between tiered storage and our current data storage method and if they can complement one another. Tiered Storage is a new feature in Axon Server Enterprise Edition that will be available sometime in the first quarter of 2023.    If you are interested in trying this and other unique Axon Server EE features, don't hesitate to get in touch with us. You can try Axon Server EE for free!

In this portion of our conversation, Dominic talked about how ABAC can be used to secure Axon applications. He explained the spring boot integration, Axon's command side, and the query side. He talked about the annotation he introduced in his framework that integrates very nicely with the axon framework. He also talked about integration, how it can be deployed, and what kinds of support are offered for authoring policies. Dominic talked about this topic during our conference in September of last year in Amsterdam, and I will include the link to that talk and other helpful information in the notes.   Here is Dominic's presentation at our 2022 AxonIQ Conference in Amsterdam.    Below are some resources to learn more about our topic of conversation and Dominic's research: FTK Institute: https://www.ftk.de/ SAPL Website: https://sapl.io/ SAPL Playground: https://playground.sapl.io/ SAPL Demos (Including Axon Demo) on GitHub: https://github.com/heutelbeck/sapl-demos Connect with Dominic on LinkedIn and GitHub.  Connect with Sara on LinkedIn and Twitter.  For more information about us, visit axoniq.io

I recently had the pleasure of talking with Dominic Heutelbeck about Attribute-Based Access Control. Dominic is a computer science professor leading the FTK (Forschungsinstitut für Telekommunikation und Kooperation e.V.) Research Institute in Dortmund, Germany.  In the first portion of our talk, Dominic explained what access control is and its importance. He also explained what Attribute-Based Access Control is and why one would want to use it. He explained policies, differences between traditional ABAC and existing standards, such as XACML, and much more.  In the next portion of our conversation, Dominic will explain how ABAC can be used to secure Axon-based applications.  Below are some resources to learn more about our topic of conversation and Dominic's research: FTK Institute: https://www.ftk.de/ SAPL Website: https://sapl.io/ SAPL Playground: https://playground.sapl.io/ SAPL Demos (Including Axon Demo) on GitHub: https://github.com/heutelbeck/sapl-demos   Connect with Dominic on LinkedIn and GitHub.  Connect with Sara on LinkedIn and Twitter.  For more information about us visit axoniq.io  

Sara spoke with colleague and software architect Frederic Gendebien about possible patterns one can use when designing a distributed CQRS system. Frederic broke these patterns into five distinct ones, with a message router connecting them to simplify communication. He described which patterns can be bundled together regarding business decisions and deployment. Frederic gave a presentation on the topics relating to our conversation, which you can find on our YouTube channel. Connect with Frederic on LinkedIn and Twitter.

In this episode, Sara spoke with a few members of the Axon Server team about our newest product, Axon Synapse. The Synapse makes it possible for all applications, regardless of the language, to use an HTTP bridge to access Axon Server and use it. Therefore, there is no need to use Axon Framework or a plugin to use Axon Server. They discussed the benefits of using the Synapse and some pitfalls.    You can try Axon Synapse's beta version and let us know about your experience. We are very much interested in your feedback, so please don't hesitate to let us know through our Discuss platform.    Connect with Marc on LinkedIn.  Connect with Marco on Twitter.  Connect with Michal on LinkedIn.    Connect with Sara on LinkedIn and Twitter.    For more information about us, visit axoniq.io

In this episode, Sara speaks with colleague and lead developer of Axon Framework, Steven van Beelen about AxonIQ's newest, most anticipated feature of Axon Framework 4.6: the Dead-Letter Queue.  Steven explains what DLQ is and why it's been implemented in our framework. He also speaks about how the users can benefit from it, when to enqueue a message and when not to, where the dead letters are stored, and which infrastructure components are supported in AF DLQ. He also touches on what type of messages the DLQ can be used for and what the logs would look like with out-of-the-box configurations, and whether or not they can be customized.    Steven will present a FREE webinar on DLQ in Axon Framework on December 6th, 16:00 CET. You can find more information on how to register for this webinar here. We hope to see you there.    To find out more about DLQ and code samples, please visit our Reference Guide.    Connect with Steven on LinkedIn and Twitter.  Connect with Allard on LinkedIn and Twitter.   Connect with Sara on LinkedIn and Twitter.  For more information about us, visit axoniq.io
