ADSD with SOA and Udi – Day 1

I am learning this week.

Advanced Distributed Systems Design with Udi Dahan.

So far, I have acquired many new questions that I didn’t think I had need of, and I am hopeful that in another 4 days they will all have disappeared again whence they came. I am an optimist.

One thing missing from the copy of the slides we all got was the reference table for quick lookup of relative latencies in computers; it’s good to keep in mind how much slower memory is than the CPU, and how much slower an SSD is than memory, and network than SSD and reboots beat everything. I kinda feel an urge to start suffixing method names for nasty latency surprises to make it a bit more obvious.

As my mind wandered onto tangents, Conway’s Law took on a whole new dimension too. I wonder if software organisations should ever re-structure if there isn’t a need for software re-architecture.

I have so many provocative notes in my little booklet that I’m not sure how to turn into cohesive provocative statements. I’m also not sure which ones I actually believe yet, so maybe I will have a more nuanced view to filter them through towards the end of the week.

There are definitely things I disagree with, possibly strongly, but I haven’t given them as much thought as Udi, so I do not feel qualified to disagree overtly just yet.

First, I need to get through all these damned questions.
