AWS Fault Injection Simulator [FIS] #how-to-use

Pancho Daskalov — Wed, 05 Jul 2023 19:29:59 +0000

AWS FIS concepts

AWS FIS allows you to test the performance of an application or system under fault conditions by running experiments on your AWS resources. To conduct experiments, create an experiment template that outlines the actions, targets, and stop conditions. Use the template to run the experiment and monitor its progress until all actions are completed.

AWS FIS example

For the FIS experiment we've created an EC2 instance with the following parameters:

Platform: Amazon Linux
AMI ID: ami-06b09bfacae1453cb
AMI Name: al2023-ami-2023.1.20230629.0-kernel-6.1-x86_64

Now, we will move on to creating AWS FIS experiment which will have following set of actions:

create experiment template - this is broken down into several steps: Description and Name, Actions, Targets, Service Access, Stop Conditions, Logs, Tags

We need to provide description for our experiment, Name is optional here!

We add actions to an experiment template, which AWS FIS uses to run the experiment.

AWS FIS identifies all targets before starting any action and uses them throughout the experiment.

FIS requires permission to conduct experiments on our behalf.

Once we've completed all the steps required we can go ahead and click on the 'create experiment template'.

This will trigger the creation of the experiment template which once ready will show up in the experiment templates dashboard.

Then we need too select the experiment template and click on 'start experiment' in order to initiate the AWS FIS experiment.

You will be prompted with a window which warns you that you are about to 'perform destructive actions on your AWS resources.' Write 'start' in order to confirm the action!

Next, we need to switch over to the Experiments tab, as the experiment once initiated will be in a 'Running' state.

Now if we switch over to the EC2 instance dashboard, we will notice that the instance changed its status to 'Stopping' due to the AWS FIS experiment action to stop it.

Eventually, the ec2 instance comes to a complete stop and changes its status to 'Stopped'.

AWS Fault Injection Simulator [FIS] #explained

Pancho Daskalov — Tue, 04 Jul 2023 20:01:30 +0000

Introduction:

Ensuring the resilience and reliability of cloud applications is a critical aspect of modern software development. To help developers and operators test their systems' response to failures and improve their fault tolerance, Amazon Web Services (AWS) has introduced the AWS Fault Injection Simulator. This powerful tool allows users to simulate various failure scenarios in their AWS environments, helping them proactively identify and mitigate potential issues. In this article, we'll explore the capabilities of the AWS Fault Injection Simulator and provide a sample Terraform code to get you started.

Understanding AWS Fault Injection Simulator:

The AWS Fault Injection Simulator is a fully managed service that allows you to inject faults into your AWS infrastructure. By simulating different failure scenarios, you can evaluate how your applications and systems respond under stress and ensure they gracefully handle failures. The simulator enables you to test the resiliency of your applications, identify potential bottlenecks, and validate your disaster recovery strategies.

Benefits of Using AWS Fault Injection Simulator:

1. Proactive Resilience Testing:

By injecting faults into your environment, you can proactively identify weak points in your infrastructure, applications, and configurations, allowing you to make improvements before real failures occur.

2. Realistic Failure Scenarios:

The AWS Fault Injection Simulator provides a wide range of pre-built failure scenarios, such as network partitioning, instance failures, and throttling errors. These scenarios closely resemble real-world failures, ensuring accurate testing.

3. Fine-Grained Control:

You have granular control over the fault injection process, allowing you to select specific targets, configure fault parameters, and customize the duration and intensity of the fault injections.

4. Automated Fault Injection:

The AWS Fault Injection Simulator supports automation through integration with AWS Systems Manager Automation, making it easier to schedule fault injection campaigns, run experiments, and collect data.
