Why Distributed Systems Fail (And How Elite Engineers Prevent It) #DistributedSystems #SystemDesign #SoftwareEngineering

Most production outages don’t happen because software breaks. They happen because systems fail badly. Learn the real engineering behind building resilient distributed systems: circuit breakers, retry storms, load shedding, fault isolation, chaos engineering, and AWS-scale resilience patterns. A must-read deep dive for software engineers, architects, and engineering leaders building systems that must stay online. #DistributedSystems #Microservices #SystemDesign #ResilienceEngineering #Java #AWS #SoftwareArchitecture

If the Transaction Coordinator crashes after collecting votes but before sending its decision, participants remain blocked until recovery. This blocking behavior is a known limitation of 2PC in distributed fintech systems.

Artemis II fault tolerance

Communications of the ACM had a fascinating post about how NASA built Artemis II’s fault tolerant computer. 3 fascinating excerpts. (1) Eight modules with several back up scenarios: “Or…

If a lock holder crashes, the lock must expire via time-to-live. If the TTL is too short, a slow process may lose its lock while still executing, allowing a second process to proceed — a correctness failure in fintech.

Consensus requires a quorum — a majority of nodes — to agree before a value is committed. This majority requirement is what allows the system to continue despite node failures.

So apparently, NASA's secret sauce for building a "fault-tolerant" computer involves getting blocked by #Cloudflare while trying to access the article. 🚫✨ Who knew #cybersecurity was just a fancy way of saying you can't read about computers? 🤖🔒

For those with more than a passing interest in Information Systems security (OK not everyone🤣) , this might prove to be interesting. Although as commented,

’build the governance first, get the key parties committed, define the trust roots, enforce the rules – is precisely the kind of process that works in Switzerland and struggles almost everywhere else.’

Switzerland built a secure alternative to BGP. The rest of the world hasn't noticed yet
