The company operates a proprietary 3D optimization tool called RapidPipeline, previously known as RapidCompact. The platform processes 3D models for customers via a combination of worker servers and API servers. This infrastructure faced the following challenges:

After a detailed analysis of the existing infrastructure, the following measures were implemented: 

Before the new architecture was implemented, it was difficult to take various load requirements into account. New servers had to be added manually and computing power was not used efficiently.

For example, instances had to be started up via CLI command if the number of jobs in the queue became too high. There was no automation for this.

With the introduction of Auto Scaling Groups (ASGs) and the associated configuration, it is no longer necessary to run servers on spec. If the load exceeds a defined level, additional servers are automatically added and then shut down again. Critical parts of the infrastructure have been outsourced and are executed serverless using AWS Lambda. This ensures that these operations are completely excluded from potential downtimes of the main application. This ensures that costs are reduced while unexpected load peaks are absorbed.

In addition, the entire infrastructure has been moved to CDK so that every change can go through a code review, making the entire system more resistant to failures.

The infrastructure is now able to adapt optimally to different load scenarios in order to keep costs low and minimize waiting times.

This guide will show you how to automate the process of MFA authentication to access your AWS CLI with a YubiKey. With a simple command, you can generate and inject temporary session credentials directly into your AWS configuration, making your access seamless.

Here’s the problem: AWS MFA works great for console access, but when it comes to the CLI, it gets tedious. If your account enforces MFA for CLI operations, you need to generate a session token manually like this:

Doable, but repetitive and error-prone. When you're in the middle of debugging a Lambda function or deploying infrastructure with CDK, this is the last thing you want to deal with.

Now let's look at it using the YubiKey and some simple bash scripting. With the companion CLI 

 and the YubiKey plugged in, we can streamline this process:

. Once set up, you should have the ARN of your MFA device handy.

To automate AWS MFA, your YubiKey must be registered as a TOTP-based MFA device in your AWS account.

Now as we successfully registered the Yubikey as MFA device, we can continue automating the session token insertion.

Step 2: Automate AWS CLI Session Generation

 and the MFA Identifier of your Yubikey at hand. You can find the identifier on the AWS 

You can now manage your MFA restricted AWS accounts without manually dealing with session tokens and with minimal scripting.
