Overview

  • It all starts with CI/CD pipelines that deploy code to the server instances. Tools like Jenkins and GitHub help over here.
  • The user requests originate from the web browser. After DNS resolution, the requests reach the app servers.
  • Load balancers and reverse proxies (such as Nginx & HAProxy) distribute user requests evenly across the web application servers.
  • The requests can also be served by a Content Delivery Network (CDN).
  • The web app communicates with backend services via APIs.
  • The backend services interact with database servers or distributed caches to provide the data.
  • Resource-intensive and long-running tasks are sent to job workers using a job queue.
  • The full-text search service supports the search functionality. Tools like Elasticsearch and Apache Solr can help here.
  • Monitoring tools (such as Sentry, Grafana, and Prometheus) store logs and help analyze data to ensure everything works fine.
  • In case of issues, alerting services notify developers through platforms like Slack for quick resolution.
