AWS DocumentDB

Amazon DocumentDB (with MongoDB compatibility) is a fully managed native JSON document database that simplifies running critical document workloads at virtually any scale without the need to manage infrastructure, making it cost-effective and easy to use.

Benefits of Using DocumentDB:

  • MongoDB Compatibility: Supports popular MongoDB APIs, allowing easy migration from MongoDB.

  • High Performance & Scalable: Distributed storage architecture enhances read/write speed and automatically scales as needed.

  • Easy Management: As a fully managed service, it reduces database administration overhead.

💰 Pricing of Amazon DocumentDB

The cost of Amazon DocumentDB depends on the following factors:

  • On-Demand Instances – Charged per hour based on instance type.

  • Database I/O – Charged per million read/write operations.

  • Database Storage – Charged per GB per month.

  • Backup Storage – Charged per GB per month beyond database storage.

AWS provides two pricing options:

  • Amazon DocumentDB Standard (Pay-as-you-go I/O)

    • Suitable for workloads with low to medium I/O.
    • Charges include four factors: Instance, Database I/O, Storage, and Backup.
    • If I/O costs are less than 25% of the total cost, this is a suitable option.

  • Amazon DocumentDB I/O-Optimized (Includes I/O costs in instance pricing)

    • Ideal for high I/O applications requiring predictable costs.
    • Charges only three factors: Instance, Storage, and Backup.
    • No separate I/O charges, making cost estimation easier.
    • If I/O costs exceed 25% of the total, this is the recommended choice.

Which Configuration to Choose for This Workshop?

  • We will choose Amazon DocumentDB Standard to optimize costs because:

    • Initial query volume is low.
    • Pay only for actual I/O usage.
    • Flexible upgrade to I/O-Optimized when queries increase.

Creating a DB Instance on AWS

  1. Log in to the AWS Management Console and open Amazon DocumentDB

  2. Create a DocumentDB Cluster Cluster-interface.png

  3. In Create Amazon DocumentDB cluster, enter the following details:

    • Cluster type: Instance-based cluster
    • Cluster identifier: docdb-nextjs-workshop
    • Engine version: Select the latest version
    • Cluster storage configuration: Amazon DocumentDB Standard
    • Instance class: db.t3.medium
    • Number of instances: 2 (1 Primary + 1 Replica)
    • Connectivity: Connect to an EC2 compute resource
    • EC2 Instance: Select the created EC2 instance
    • Username: user123
    • Password: user1234
    • Subnet group: Select the subnet group created in 3.3
    • VPC security groups: private-sg-documentdb (VPC)
    • Deletion protection: Uncheck Enable deletion protection
    • Review the settings and click Create cluster create-1.png create-2.png create-3.png create-4.png create-5.png create-6.png
    • Cluster successfully created create-success.png

  4. Verify Connection from EC2 to DocumentDB

  • Open the newly created cluster, go to the Configuration tab, and copy the Cluster endpoint copy-cluster.png

  • In EC2, click Connect and then click Connect under the EC2 Instance Connect tab.

    $ sudo apt-get install -y netcat
$ nc -zv docdb-nextjs-workshop.cluster-c10k88ou8amc.ap-southeast-1.docdb.amazonaws.com 27017
