Emre Akış
System Architect @Scalefocus
Title : Software Architect role or title?
Description : Nowadays, while there is still high demand for software architects in traditional teams, autonomous units usually prefer software architecture independence. Therefore, company/team-based unique team structures come up with different solutions for different software architectural needs. Many roles and titles are all over the place when they need a common foundation for some software architecture-related topics. This talk will try to cover some key issues as well as the pros/cons of having an architect when creating a product.

Title : Testing as a Service: Reusable Test Functions to Reduce Duplication
Description : Software testing is becoming more challenging every day. Along with the technical requirements, we have to cope with a very dynamic way of development and an intense scope to be handled in a limited time. While several teams or groups are trying to cope with these challenges, we observe:
There is no standard among these teams: Each is following a different approach/strategy
Some of them are struggling with problems, which were solved by others.
Inefficiency due to duplication.
To remove the imbalance, support those who are struggling with the problems that were solved by others, and ensure the code quality in all test frameworks used by several teams, we come up with the centralized test framework development idea.
The motivation was to develop a framework in which the most common problems were handled and serve the teams. Let’s talk about what the steps for this initiative are, What are the challenges and solutions, and most importantly what are the key benefits of developing a platform framework and serving as a TaaS.

Title : Why and How to Upgrade to Java 17 (and Prepare for 21)
Description : Java upgrades are sometimes seen as difficult and many applications are still running on an older version of Java. This session describes Java’s current six months release process and why applications should use a recent Java version. After that, I’ll explain the challenges of upgrading and provide some useful tips to make the process easier.
Concrete examples (including solutions) will be used to show you what changed in which version of Java and how to handle the changes. After this session you’re ready to upgrade your applications to Java 17 and prepare for Java 21.

Title : Intro to Java Development with Quarkus
Description : Java is a great programming language, however ‘traditional’ Java isn’t so great to work with when it comes to modern, Cloud Native development. Quarkus is a (fairly) new Java stack that addresses issues such as the typical slow startup time and rather large memory usage that hinder the adoption of Java in container and/or Serverless workloads. Quarkus is not just useful for optimizing resource usage though. There is also a big focus on improving the developer experience. In this session we’ll demonstrate how Quarkus is very easy and enjoyable to work with and allows developers to work with native GraalVM builds, containers and external dependencies such as databases, Kafka clusters, Kubernetes etc without being experts in any of these technologies (or even having to install them locally). After this session, the audience should come away with inspiration to build modern Cloud Native applications with Java, and have fun doing so!

Title : Enter Serverless Functions Journey with Quarkus (Workshop)
Description : This workshop is designed to be a hands-on experience on how developers can build agnostic serverless Java functions using Quarkus, a new Kubernetes native Java framework with familiar tools (e.g. CLI, Maven, Gradel). The workshop covers deploying service functions to AWS Lambda, optimizing the functions, making them portable across multiple serverless platforms ( e.g., AWS Lambda, Azure Function, Google Cloud Platform, Kubernetes Knative), and using the latest handy command-line tool (e.g. Kn func) to enable a Buildpack for function development & deployment in minutes. Lab participants will be provided a free sandbox for serverless deployments.
The workshop attendees need to bring their own laptops to go through the lab. I’ll also provide the way individual developers sign in a sandbox(free) for serverless function deployment. The workshop guide (WIP) is here - http://bit.ly/quarkus-serverless-labs
