strangler-fig pattern vrši inkrementalnu migraciju: obtlačite monolith sa slojem usmjeravanja, izvucite jednu mogućnost u servis, i preusmjerite promet prema njemu — dok monolith nije "ugušen". Nema big-bang rewrite.
Kako funkcionira
Step 1: route all traffic through a facade/proxy to the monolith
Step 2: extract ONE capability → new service
Step 3: route just that path to the new service
Step 4: repeat; delete that code from the monolith
Client ─▶ [ Proxy ] ─┬─▶ /orders ─▶ NEW Orders service
└─▶ everything else ─▶ Monolith
