MongoDB Atlas on AWS: Step-by-Step

Let’s walk you through the detailed process of setting up and effectively utilizing MongoDB Atlas, a cloud-based database service, specifically within the Amazon Web Services (AWS) environment.

Prepare Your AWS and MongoDB Accounts

Before deploying MongoDB Atlas on AWS, you must prepare both your AWS and MongoDB Inc. accounts. This involves activating MongoDB Atlas CloudFormation resource types in your desired AWS Region. For those deploying in a region for the first time, this step is mandatory. However, for subsequent deployments in the same region, you can bypass this by setting the “ActivateMongoDBResources” parameter to “No“.

Next, you need to generate a MongoDB Atlas programmatic API key with the necessary permissions and network access. This key allows AWS CloudFormation to authenticate with the MongoDB cloud.

Once the programmatic API key is created, it must be stored securely in AWS Secrets Manager. You need to follow a specific naming convention: “cfn/atlas/profile/${ProfileName}“. This ensures secure and organized access to the API keys.

Deploy MongoDB Atlas on AWS

The deployment process begins by signing into your AWS account and launching the MongoDB Partner Solution. This step involves navigating the AWS CloudFormation console and using the pre-populated template. Make sure you choose the correct AWS Region for your deployment.

In the deployment process, you’ll encounter two pages where you must provide specific inputs and customize settings: Specify stack details and Configure stack options. It’s important to give careful attention to these details, as they determine the performance and security of your MongoDB Atlas deployment.

While most parameters have default settings, some require customization based on your specific requirements. Notably, the parameters QSS3BucketName, QSS3BucketRegion, and QSS3KeyPrefix should typically remain unchanged unless you are customizing the Partner Solution templates or have specific instructions to modify them.

The final step in the deployment process is to select the necessary capabilities and create the stack. This process usually takes about 10-20 minutes. Upon completion, the status CREATE_COMPLETE indicates that your MongoDB Atlas deployment is ready.

Post-Deployment Steps

Once the deployment is complete, it’s important to test the setup. There are two primary ways to test your deployment: accessing the MongoDB Atlas web console using the new project ID or using the Mongo shell. This will help you ensure that your deployment is configured correctly and functioning as expected.

MongoDB Atlas on AWS Best Practices

MongoDB Atlas on AWS offers invaluable insights and recommended strategies for optimizing the utilization of MongoDB Atlas, a cloud-based database service, within the Amazon Web Services (AWS) infrastructure.

Choose the Right AWS Instance Type

AWS offers a variety of instance types that are optimized to fit different use cases. Your choice should be based on your workload requirements, such as CPU, memory, storage, and network performance.

For example, if you have a memory-intensive workload, a memory-optimized instance like the R5 series would be a good fit. If your application requires high I/O operations, you might consider I3 instances, which offer high disk I/O performance. For general purposes, M5 instances provide a balance of compute, memory, and network resources.

It’s also important to select the right instance size within the instance type. AWS provides a range of sizes, from micro instances for small workloads to 16xlarge instances for enterprise-scale applications.

Configure VPC and Security Groups

A VPC is a virtual network dedicated to your AWS account. It allows you to control your network environment, including selection of IP address range, creation of subnets, and configuration of route tables and network gateways. When setting up your MongoDB Atlas on AWS, it’s important to create a VPC that’s exclusively for your MongoDB instances to isolate them from other services.

Security groups act as a virtual firewall for your instance, controlling inbound and outbound traffic. For MongoDB, it’s recommended to restrict inbound traffic to only necessary IP addresses and to limit outbound traffic to the IPs of your application servers. This minimizes the exposure of your database to potential threats.

Monitor Performance Metrics

Monitoring is an integral part of running MongoDB on AWS. MongoDB Atlas provides a dashboard that displays key performance metrics such as operations counters, disk usage, connections, network, and CPU usage. Atlas’s real-time performance panel provides insights into slow-running queries, allowing you to identify and resolve performance issues quickly.

In addition, you should use AWS CloudWatch to monitor the MongoDB database. By integrating Atlas with CloudWatch, you can correlate database performance with application and system metrics, helping you gain a holistic view of your operations.

Monitor and Optimize Your Costs

AWS Cost Explorer is a user interface that lets you visualize, understand, and manage your AWS costs and usage over time. You can view data up to the last 13 months, forecast how much you’re likely to spend for the next three months and get recommendations for cost-saving opportunities.

MongoDB Atlas also offers cost management tools, including detailed usage breakdowns and cost projections. It provides insights into which clusters are driving costs, allowing you to make informed decisions about resource allocation.

To optimize costs, consider strategies like right-sizing instances, leveraging reserved instances for predictable workloads, and using auto-scaling to adjust resources based on demand. Regularly reviewing your cost reports can also help you identify unnecessary expenses and potential saving opportunities.
