Chaos Engineering and Resilience Culture: Testing Failure Before It Happens

by

Distributed Systems Series — Part 4.9: Fault Tolerance & High Availability The Gap Between Designed Resilience and Actual Resilience Parts 4.1 through 4.8 have established the complete fault tolerance and high availability engineering stack. Post 4.1 defined the failure taxonomy. Posts 4.2 and 4.3 established the fault tolerance and redundancy foundations. Post 4.4 covered failure … Read more

Fault Isolation and Bulkheads in Distributed Systems: Limiting the Blast Radius of Failures

by

Distributed Systems Series — Part 4.7: Fault Tolerance & High Availability Failures Are Inevitable — Outages Are Not Every large distributed system experiences component failures continuously. Nodes crash, networks degrade, downstream services slow, disks fill, processes run out of memory. The engineering discipline is not preventing these failures — that is impossible at scale — … Read more
