1 – It all starts with CI/CD pipelines that deploy code to the server instances. Tools like Jenkins and GitHub help over here.

4 – The requests can also be served by a Content Delivery Network (CDN).

5 – The web app communicates with backend services via APIs.

6 – The backend services interact with database servers or distributed caches to provide the data.

7 – Resource-intensive and long-running tasks are sent to job workers using a job queue.

8 – The full-text search service supports the search functionality. Tools like Elasticsearch and Apache Solr can help here.

9 – Monitoring tools (such as Sentry, Grafana, and Prometheus) store logs and help analyze data to ensure everything works fine.

10 – In case of issues, alerting services notify developers through platforms like Slack for quick resolution.
