Error Model Reading
It’s taken me a while to get round to reading Joe Duffy’s Error Model article – mainly due to the length of the article 🙂 However, like most things Joe write, its full of useful information.
Principles at the beginning of the article appropriately sets the stage for the reminder of the article. A number of people could learn a lot from Joe’s writing style and format. Context is key.
Its nice to see a lot of references to the Go language through the article. Also, the “Let it crash” and Netflix’s Chaos Monkey references 🙂 in the Reliability, Fault-tolerance, and Isolation section 🙂
The “lightweight nature of Midori processes” seems to have been a key design decisions. In many ways its sad that Midori never saw the light of day outside of Microsoft
Despite us beginning with Singularity, which used Sing#, a variant of Spec#, we quickly moved away to vanilla C# and had to rediscover what we wanted. We ultimately ended up in a very different place after living with the model for years.
If you don’t have time to read the full article, then at least read the Retrospective and Conclusions 🙂 Microsoft Edge took advantage of abandonment in a few areas based on the Midori work, coupled with consideration to bring contracts to C++.
