Service Mesh
Service, mesh, (jaise, Istio, Linkerd) EK, DEDICATED, INFRASTRUCTURE, LAYER, hai, JO, service-to-service, communication, ko, HANDLE, karta hai — "SIDECAR" PROXIES, (HAR, service, ke, saath, DEPLOYED) automatically, RETRIES, encryption, aur, OBSERVABILITY, ko, HANDLE, karte, HAIN.
Ye, LOGIC, (retries, circuit, breaking, mTLS) APPLICATION, CODE, se, "OUT" nikalke, INFRASTRUCTURE, mein, MOVE, karta hai — DEVELOPERS, ko, ISE, MANUALLY, IMPLEMENT, karne, ki, ZAROORAT, NAHI, PADТI, HAR, service, mein.
# Sidecar pattern — HAR, pod, mein, DO, containers:
# 1. order-service (application, code)
# 2. envoy-proxy (sidecar — traffic, ko, intercept, karта, hai)
# Application, code, ko, PATA, hi, NAHI, ki, mesh, exist, karta, hai- Service mesh = dedicated, infrastructure, layer, service-to-service, communication, ke, liye
- Sidecar proxies, HAR, service, ke, saath, DEPLOYED, hote, hain
- Retries/encryption/observability, application, code, se, "out" nikal, jaate, hain
Service, mesh, se, CANARY, deployments, aur, A/B, testing, ke, liye, FINE-GRAINED, traffic, splitting, ki, ja, sakti, hai — application, code, mein, KUCH, CHANGE, kiye, BINA — SIRF, mesh, CONFIGURATION, se.
# Istio VirtualService — traffic, split:
# 90% → v1, 10% → v2 (canary)Service, mesh, AUTOMATICALLY, METRICS, aur, TRACES, GENERATE, karta hai HAR, service-to-service, call, ke, liye — application, code, mein, MANUALLY, instrumentation, ADD, karne, ki, ZAROORAT, KAAFI, kam, ho, jaati hai.
