Episode 78: Fault Tolerance with Bob Hanmer Pt. 2

This is the second part of the discussion on fault tolerance with
Bob Hanmer (if you didn't listen to Episode 77, which contains part
one, please go back and listen now; this episode builds on that
previous one!) We start by discussing a set of error detection
patterns. Among are the well-known approaches such as checksums and
voting. We then look at error recovery patterns, including restart,
rollback or roll forward. The next section looks at error
mitigation patterns, which include shedding load and doing fresh
work before stale. The last patterns section then looks at fault
treatment patterns. We conclude the episode with a small discussion
about how to design systems using (these and other) patterns, and
with some thoughts on why actually wrote the book.
