Create Infrastructure as Code for Python Applications

As a Python developer, you excel at crafting efficient and elegant code, focusing on building robust applications and innovative features. However, when it comes to deploying your Python application to AWS, the intricacies of creating infrastructure as code (IaC) can be a stumbling block. You want to concentrate on what you do best—writing Python code—without getting bogged down in the complexities of provisioning and managing the cloud platform resources that your application depends on. While the cloud offers easier deployment, it often demands infrastructure expertise that can slow you down. Fortunately, there are solutions to help you move faster and keep your focus on development.

Where to Start: Writing Your IaC

You have a few places to start when writing your IaC: 

Start from Scratch

Whether you are using Terraform, Chef, Puppet, Pulumi, Ansible, or others, you'll need to create configuration files that declare your desired state. With Terraform specifically, you'll write your configuration file (`.tf` files), a variable declaration file (`variables.tf` or `variables.tf.json`) to declare input variables, and variable definition files (`terraform.tfvars`) to assign values to the input variables. After running `terraform plan` to confirm your infrastructure and `terraform apply`, you will get a state file (`terraform.tfstate`) that stores information about the managed infrastructure. This process is not easy! It requires extensive knowledge about your infrastructure, security policies, and resource requirements, all beyond how you want your application to run.

Use a Template

Fortunately, DevOps and platform engineers have created templates that can save you time. However, templates present challenges: 

  1. You still need to know what information to fill in, often requiring a treasure hunt for details.
  2. Templates can become outdated quickly, introducing risks to your Python application if they aren't up-to-date.

Generate Infrastructure from Code

You've already spent a lot of time developing your Python application and codifying infrastructure choices. What if you could create your IaC from your application code? Infrastructure from code allows you to do just that.

Infrastructure from Code for Python Applications

Infrastructure from Code treats your Python application as the source of truth. It auto-generates IaC from the application code itself, standardizing and streamlining cloud deployments. This approach doesn't require any changes to your application source code. Using infrastructure from code can save you a lot of time, creating IaC that adheres to best practices and policies, including AWS and Azure policies, the AWS Well-Architected Framework, and compliance standards like SOC 2, HIPAA, NIST, CIS, GDPR, and more.

While infrastructure from code is a new approach to IaC generation, it is a streamlined and efficient solution for easier application deployment.

Try Infrastructure from Code for Your Python App

If you have a Python application and want to try infrastructure from code, appCD offers three ways to get started. First, the Playground allows you to explore how appCD works without needing to connect anything; you can see a sample repo and how it generates IaC with policies applied. Second, the Dev Edition, which is free to use, is a SaaS-based version where you can connect your repos, view your deployment architecture, select AWS policies and compliance standards, and generate your IaC. From there, you can create a pull request and follow your standard CI/CD process. Finally, if you prefer not to use a UI, you can use the CLI to create your IaC, following a similar process as outlined in the documentation.

4 Easy Steps to Generate IaC for Your Python Application

Once you’ve set up your free appCD account by logging in with GitHub, GitLab, or Google, follow these four steps to generate your IaC to deploy your Python application:

1. Connect a Repo

Ensure appCD has access to the repos you use to build your application, whether they're several repos of various microservices or one monolith repo. If you don't see the repos you need listed when you click "Repositories" in the left-hand navigation bar, you'll need to connect the repos to appCD.

2. Create an appStack

To get the IaC files your application needs, create an appStack. You have two options:

  • appCD can scan your code and generate IaC for you.
  • You can use our visualizer to drag and drop infrastructure components to create your deployment architecture.

3. View and Edit the Deployment Architecture

Once you’ve connected your repo, selected the language, cloud, and policies you want to apply, create an appStack. You can then view your architecture and make any necessary changes using the drag-and-drop feature.

4. Generate IaC Files

After finalizing your architecture, export your IaC and follow your usual deployment process.

Auto-generate your infrastructure as code in minutes instead of days or weeks. You no longer need to be an infrastructure expert and can focus on the development work you were hired to do.

Try appCD to generate your infrastructure from code.
