Atlas Deployment Tasks

Introduction

Atlas tasks teach the cloud-ops side of MongoDB: provisioning clusters, configuring networking, enabling Search, wiring observability — the day-one tasks of every cloud team adopting MongoDB.

Understanding the topic

8 hands-on Atlas tasks:

• 1. Create a free-tier cluster, restrict IP allowlist, create a database user.
• 2. Enable continuous backup + point-in-time restore.
• 3. Configure PrivateLink (AWS) or VNet peering (Azure).
• 4. Add an Atlas Search index over a products collection.
• 5. Add a Vector Search index over chunked documents.
• 6. Enable Atlas Auto-Scaling for storage + compute.
• 7. Stream metrics to Datadog via the OTLP exporter.
• 8. Provision everything in task 1–7 via Terraform.

Informative example

Task 4 — Atlas Search index in JSON:

{
  "mappings": {
    "dynamic": false,
    "fields": {
      "name":        { "type": "string" },
      "description": { "type": "string" },
      "category":    { "type": "stringFacet" },
      "price":       { "type": "number" }
    }
  }
}

Best practices

• Do the manual UI version once for understanding, then immediately codify in Terraform.
• Never leave the IP allowlist as 0.0.0.0/0 beyond a quick demo.
• Enable backup and audit before any data goes in.
