AWS taps TLA+ and P language to hammer out service correctness. Bugs quiver and deadlines whistle past with formal methods wielded like a scalpel. Enter PObserve—this tool is the wizard that conjures log validation magic between design and production. And P? It’s the S3 whisperer, driving sudden consistency gains and cunning optimizations. Formal methods can be a beast, but AWS rides it like a bull, mixing formal proofs with real-world clout. Case in point: a sprightly 94% RSA throughput boost on ARM CPUs.
