Continuing on our survey of architectural styles, this month we brush against Orchestration-driven Service-oriented Architecture (SOA), a dinosaur that roamed the earth more than a decade ago but contains many lessons that led to microservices and related architectures. In this episode, we describe the topology of SOA, the goals and motivations, and why it failed, along with some important lessons. Not just rants about the problems in SOA (although there are a few), this episode highlights how and why we went through that architectural waystation.

No, it has nothing to do with outer space but rather tuple space. We continue our survey of architectural styles with an exotic one, Space-based architecture, which answers the question: how can you design an architecture that can handle several hundred thousand simultaneous requests...before cloud providers existed. Today, this architecture style is used for caching and other high volume problems. Join us as we describe this architecture style, how it works, what's good and bad, and how it's still useful today.

We continue our survey of architectural styles with a widely misunderstood one, Event-driven Architecture. The first thing we attack on this episode is how this style and microservices are alike and, more importantly, differ. We talk about common usages of this style, variations based on events versus messages, data strategies, and a host of other details, some not found in the book (including some extended metaphors). Join us as we cover one of the most powerful distributed architecture styles.
