How's your architecture game? Carl and Richard talk to Thomas Betts about being a better architect. Thomas focuses on the key aspect - communication! An effective architect can talk to all the stakeholders in the language of the stakeholder, whether that's speaking business with business stakeholders, coding with developers, and understanding the needs of the security and operations folks. All those aspects (and more) go into an effective architecture and then come the changes as the implementation challenges happen. The conversation also digs into the importance of documentation to know why decisions were made and how to change them as you respond to changing needs and landscapes.

Large Language Models like GPT-4 are all the rage - how do we use them well? Carl and Richard talk to Amber McKenzie about the challenges and concerns around LLMs, especially regarding the data involved. Amber talks about the risks of creating products around LLMs while the technology is so young and constantly evolving, especially with how the general public reacts to conversational AI. Education is key, and constantly fact-checking - good advice for a lot of technology, but LLMs are making fact checking even more important!

Microservices or Monoliths? Carl and Richard talk to Layla Porter about choosing a middle ground between microservices and monoliths, with modular monoliths. Layla talks about the pushback from the community around microservices and the insistence that there is "one right way." Monoliths have their advantages until they are a problem - but that doesn't mean that re-architecting everything is the right way to go. Chipping off parts of the monolith into satellite modules strikes a balance of flexibility and scalability - and opens the door to accessing the power of bus architectures when needed!

Databases continue to evolve! Carl and Richard talk to Ted Neward about multi-model data stores - which, these days, are most databases! Ted talks about how SQL and NoSQL are not that different - it's only a query engine. But how do you store your data? Today multi-model databases store data with multiple storage engines, and so can store your data in the most appropriate form. There are lots of choices, and it's worth digging deeper into your existing data stores, as well as the new ones available!

What can we do to make testing easier? Carl and Richard talk to Dennis Doomen about Fluent Assertions, an open-source set of extension methods to help write better tests.

The conversation also digs into how these types of open-source projects don't make money, even though they help many people. Could we fix that?

How do you scale a monolith? Carl and Richard talk to Derek Comartin about his blog posts and YouTube series around scaling a monolith. Derek talks about the tendency for folks to want to split a monolith into microservices without assessing if it will make a difference. There is no one right way! The conversation digs into different approaches to scaling - up, out, using caching, queuing, and more! There are many approaches to scaling your applications, and yes, microservices are an option, but there are many others!

Can you quit your job and work full-time on your open-source project? Carl and Richard talk to Shaun Walker about his recent move to focus on Oqtane, the open-source application framework and CMS he has been developing for the past few years. Shaun talks about recognizing when an open-source project has matured to the point that it is being held back by not also providing a commercial license. For some folks, a commercial license is not an option - they need it to be able to use the software within the company. Then comes the tricky part: Setting up a business, and balancing the needs of the open-source community with the commercial customers. It isn't easy, but it can be done!

How do you get your app running in Azure? Carl and Richard talk to Savannah Ostrowski about Azure Developer CLI (azd), an open-source tool to help developers using .NET, Javascript/Typescript, Python, Java, and more to get deployed into Azure.
