Resilience Lost in the Stack: How Abstraction Layers Silently Mask Distributed Systems’ Topology Awareness

Distributed coordination services exist for a reason, and they are the CPUs of distributed systems that give them their high availability. When it's in your stack, you assume failover is handled. Some services that operate in this layer include Apache Zookeeper, Redis Sentinel, etcd, etc. These services are mathematically engineered for HA. Protocols such as Raft/Paxos/ZAB guarantee this. We know that the DCS itself cannot go wrong as long as a quorum of nodes exists.  Here, we want to explore o
