Panel argues specific tradeoffs: start with a monolith because it’s easier for small teams and split only when uneven growth forces independent scaling… | ||
| Microservices: A retrospective | Øredev 2019 | 2019-11-06 |
Microservices are pitched as velocity, scale and resilience but the real payoff is organizational scaling: teams gain independence and less synchronization… | ||
| How shit works: Time｜ | Øredev 2019 | 2019-11-06 |
A website-builder called Wix Adi uses event sourcing and a relational DB but finds persisted events arrive out of order; system timestamps prove unreliable (OS… | ||
