Microservices Integration

Service Mesh Design

Learn how to implement Istio-style traffic management and mutual TLS authentication between services.

apiVersion: networking.istio.io/v1beta1
kind: VirtualService
metadata:
  name: yln-mesh
spec:
  hosts:
    - "ylndata.com"
  gateways:
    - public-gateway
  http:
    - route:
        - destination:
            host: primary-service-ylndata
      timeout: 15s

Distributed Tracing

Implement observability patterns using Jaeger and OpenTelemetry for request tracing across distributed systems.

Instrumentation Example

import { TracerProvider, SimpleSpanProcessor } from '@opentelemetry/tracing';
import { JaegerExporter } from '@opentelemetry/exporter-jaeger';

const provider = new TracerProvider();
provider.addSpanProcessor(
  new SimpleSpanProcessor(
    new JaegerExporter({
      endpoint: 'http://jaeger-collector:14268/api/traces'
    })
  )
)

Advanced Caching

Cache Invalidation Strategies

TTL-Based

Set time-to-live for cache entries using sliding expiration windows.

Tag-Based

Use semantic tags to group related cached entries for batch invalidation.

Adaptive

Intelligently refresh cache based on usage patterns and request frequency.

Challenge: Implement Cache Warmer

Design a system that pre-loads commonly accessed data into memory before peak hours.

Sample Input:

{
  "peak_hours": [9, 17],
  "high_priority_routes": [
    "/api/dashboard",
    "/api/users/active"
  ]
}

Deliverables:

  1. Background worker that pre-warms cache
  2. Priority-based route pre-fetching
  3. Auto-scaling integration for cache warmers
