IBM Cloud University: Build, Deploy and Scale Node.js Microservices

The document discusses key aspects of building scalable microservices including containerization, orchestration, monitoring, and performance optimization. It provides code examples for containerizing a Node.js application, deploying it with Kubernetes using a Helm chart, and implementing continuous delivery with Jenkins pipelines and DevOps toolchains. The document also covers understanding microservices performance by analyzing architecture diagrams showing public/private networks, services, and databases.

 • Provides sampling, tracing, and debug capabilities • Collects microsecond timestamps
 • Correlates data in Zipkin server • Presents data in Zipkin dashboard Request Tracking: OpenTracing and Zipkin
const zipkin = require(‘appmetrics-zipkin’); const rest = require(‘rest'); const express = require('express'); const app = express(); app.get('/', (req, res) => { rest('http://localhost:9000/api') .then(response => res.send(response.entity)) .catch(err => console.error('Error', err.stack)); }); const port = process.env.PORT || 3000; app.listen(port, function(){ logger.info(`Express listening on: ` + port); });
• Collects data from each enabled service
 • Requires /metrics endpoint providing data
 • Provides storage and correlation capabilities • Provide customisable dashboard
 • Integrates with Graphana, Graphite, etc Microservice Metrics: Prometheus
