6:15-7:45: Orchestrate the Chaos: Process Automation in Modern Architectures

A recent (2022) poll by Kong placed the average number of microservices for a single enterprise at 184! Modern architecture patterns are great at optimizing resource usage, but what happens when you need to make a critical change to one process that spans multiple shared services? Complex business processes can be difficult to manage and automate. How do you quickly implement changes while maintaining uptime? How do you introduce a new service to an existing process? In this talk, we will discuss how to use Business Process Modeling (BPM) to orchestrate and execute complex business processes in your application. Don’t let the name fool you: this is not your father’s Visio diagram. Everyone should leave this talk with a new approach to solving their orchestration complexities!

6:15-7:45: A Tour of JVM Languages

And then there was bytecode…

Tired of the same old Java program? Join us for a tour of Java Virtual Machine (JVM) languages, their unique features, and the advantages they offer to developers.

In a world where software development is constantly evolving, the JVM ecosystem provides a platform for experimentation and innovation. From Kotlin to Scala, Groovy to Clojure, the JVM offers a diverse range of tools and frameworks that cater to different programming styles and application requirements.

In this talk, we’ll explore the evolution of the JVM, the rise of alternative languages, and the impact they have on modern software development. Whether you’re a seasoned Java developer or a curious tech enthusiast, this session will open your eyes to the rich and vibrant world of JVM languages.

6:15-7:45: Design Trade offs in Modern Architectures

Over the years we have learned and applied several software design principles. Many of these principles have been very useful and have served as guiding principles and, at times, as guard rails to develop better software. However, the principles do not work in isolation. They interplay with each other and sometimes even against each other. In this presentation we will look at the trade offs in applying well known design principles within the confines of the architectures that applications may be based on.

6:15-7:45: Cloud Cost Optimization for Java Developers

Cloud usage has been soaring over the last few years, and now developers are starting to get pressure to reduce cloud spend. In this session, we’ll discuss how to optimize your cloud utilization, and hence how much your team spends, on cloud infrastructure. We’ll discuss these topics with a specific focus on Java applications:

• Architecture of your application
• PaaS, CaaS, Cloud Functions or Kube?
• JVM ramp-up & optimization time
• Headroom for variable load
• Over provision or elastic compute?
• Database and caching techniques

6:15-7:45: Evolving your APIs, a pragmatic approach

When you publish your first HTTP API, you’re more focused on short-term issues than planning for the future. However, chances are you’ll be successful, and you’ll “hit the wall”. How do you evolve your API without breaking the contract with your existing users?

In this talk, I’ll first show you some tips and tricks to achieve that: moving your endpoints, deprecating them, monitoring who’s using them, and letting users know about the new endpoints. The talk is demo-based, and I’ll use the Apache APISIX project for it.

6:15-7:45: Digital Modernization Through Accessibility

Did you know that half of the US uses their voice, daily, for web searches? Did you know that 3 out of 4 Gen Zers (people 27 years old or younger) watch videos with closed captions on all the time? These accessibility features, long associated with people with disabilities, have broken through to mainstream success and are used by nearly everybody. Are you prepared to support these features in your app or website today?

In this talk, Scott Davis (author and digital accessibility advocate) shows you how to incorporate accessibility into your software development practices by “shifting accessibility left” in the process. We’ll explore accessibility trends and demonstrate simple techniques and free tools that you can start using immediately.

About Scott Davis

Scott Davis is a Web Architect and Digital Accessibility Advocate, focusing on the multisensory aspects of web development. In a world where half of all Google searches are done by voice, and 80% of all social media videos are watched with the sound off and closed captions on, accessibility is a springboard for innovation.
