Episode 40: Interview Werner Vogels

This episode is an interview with Werner Vogels, the CTO of amazon.com. We first talked about what scalability is, and which aspects there are to scalability. We then took a brief look at the technologies used at amazon, specifically, the middleware systems and the issue of vendor lock-in. Web services, and the role of SOA was the next topic. Then we covered what a service actually is add Werner explained the term “pizza teams”. Testing and Deployment was the next topic followed by a look at architectural characteristics of scalable systems, the value of simplicity and the CAP theorem. We concluded the discussion with a brief look at the future of distributed systems

Episode 33: Service Oriented Architecture, Pt.2b

This is the second snippet of the SOA 2 double-episode. Eberhard and Markus continue the discussion with the issue of service reuse and a couple of development process issues. We also look at the duality between infrastructure development and application development in the context of an SOA. We then discuss the great spaghetti misunderstanding :-). We conclude this episode with a look at how to integrate BPM into the conceptual SOA framework we’ve built up to now, and we’ll also briefly skim over a number of technologies related to SOA.

Note that this episode, as well as the last one, is based on a set of slides; these can be downloaded from here. This episode covers slides 39 through 74.

Episode 32: Service Oriented Architecture, Pt.2a

In this, as well as in the next episode Eberhard and Markus continue their discussion about SOA (the episode got too long, so we had to split it into two … SOA 2a and SOA 2b). In this episode, we talk about the various perspectives on SOA (CBD, EAI, BPM), about fundamental requirements towards an SOA, and we discuss the role of models in defining sustainable architectures. We also discuss how a programming model based on the described approach typically looks like. We then discuss a number of issues any large-scale SOA faces (and for which the SOA paradigm does not really provide an out-of-the-box solution: In this episode we discuss data type ownership and (weak) typing of data types.
