মাইক্রোসার্ভিসেস এবং মনোলিথিক আর্কিটেকচারের মধ্যে পার্থক্য কী?

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
