# Day 40 - Infrastructure as Code - A look at Azure Bicep and Terraform
|
|

|
In this text, the speaker discusses best practices for using Infrastructure as Code (IAC) with a focus on Terraform and Azure Bicep. Here are the key points:
|
|
|
|
1. Store your infrastructure code in version-controlled systems like GitHub or Azure DevOps to enable collaboration, auditing, and peer reviews.
|
|
2. Use static analysis tools for IAC code bases to detect misconfigurations based on business practices and organizational needs.
|
|
3. Avoid deploying sensitive information (like secrets) directly within your code. Instead, use a secret manager like Key Vault (Azure), AWS KMS, or HashiCorp Vault.
|
|
4. Ensure proper documentation for transparency and knowledge sharing among team members and future coders, including inline comments and specific documentation.
|
|
5. Consider using Continuous Integration/Continuous Deployment (CI/CD) pipelines to automate the deployment process and reduce manual effort.
|
|
6. Infrastructure as Code helps ensure consistency but can be more efficient with automation tools like CI/CD pipelines.
|
|
7. Both Terraform and Azure Bicep use declarative programming paradigms, but Terraform is compatible with multiple cloud providers while Azure Bicep only supports Azure deployments.
|
|
8. Store the state files for Terraform in a back end (like Azure Blob Storage or Amazon S3) for larger deployments to maintain a single source of truth. Bicep takes State directly from Azure and does not require State files.
|
|
9. Explore additional resources available for learning more about IAC, Terraform, and Azure Bicep through links provided by Microsoft Learn (aka.ms/SAR).

Here are the main points from the video:
|
|
|
|
**Identity and Purpose**
|
|
|
|
* The purpose of infrastructure as code is to manage and configure infrastructure using code, rather than manually.
|
|
* This helps with consistency, reliability, and version control.
|
|
|
|
**Best Practices for Infrastructure as Code**
|
|
|
|
* Avoid deploying credentials or secrets inside your code. Instead, use a secret manager like Key Vault (Azure), AWS Key Management Service, or HashiCorp's Vault.
|
|
* Use documentation to share knowledge and transparency about your code. This includes comments in the code itself, as well as separate documentation.
|
|
|
|
**Tools for Infrastructure as Code**
|
|
|
|
* Use continuous integration/continuous deployment (CI/CD) tools like Azure DevOps or GitHub Actions to automate deployments.
|
|
* Consider using a secret manager to store sensitive information.
|
|
|
|
**Azure Bicep vs Terraform**
|
|
|
|
* Both are infrastructure as code languages that use the declarative programming paradigm.
|
|
* Azure Bicep is specific to Azure, while Terraform can deploy to multiple cloud providers and on-premises platforms.
|
|
* Terraform has been around longer and has a larger community, but Azure Bicep is still a viable option.
|
|
|
|
**Key Differences between Terraform and Azure Bicep**
|
|
|
|
* State handling: Terraform uses a state file to track resource modifications, while Azure Bicep takes its state directly from Azure.
|
|
* Scalability: Terraform can handle large deployments across multiple providers, while Azure Bicep is best suited for smaller-scale Azure deployments.
|
|
|
|
**Conclusion**
|
|
|
|
* The choice between Azure Bicep and Terraform depends on your organization's specific needs and goals.
|
|
* Remember to prioritize documentation, use CI/CD tools, and consider using a secret manager to store sensitive information.
