Monolitisk arkitektur bygger en applikation som en enda enhetlig modul, medan microservices arkitektur bygger den som många små, oberoende tjänster. Båda har betydande avvägningar när det gäller komplexitet, skalbarhet, distribution och teamorganisation.
Monolith vs microservices
MONOLITH → the whole application as ONE deployable unit (one codebase, one process):
✓ SIMPLE → easier to develop, test, deploy, and debug initially; no distributed complexity
✗ at scale → harder to scale parts independently; large codebase gets complex; one
deploy for everything; a bug can affect all
MICROSERVICES → many small, INDEPENDENT services (each owns a capability + its data):
✓ independent SCALING, DEPLOYMENT, and teams; tech flexibility; fault isolation
✗ DISTRIBUTED COMPLEXITY → network calls, data consistency across services, deployment/
operations complexity, debugging across services, more infrastructure
