Managing Infrastructure as Code with Azure Bicep: 2025 Guide

Managing infrastructure as code has become an indispensable part of modern software development processes.

As of 2025, Azure Bicep stands out as a significant tool, particularly in the realm of cloud infrastructure management. Developers and system administrators can manage resources more systematically, readably, and sustainably with Bicep. Recently, a project I worked on using Bicep reminded me once again of the advantages this tool provides. So, what does this mean? Let’s explore together.

What is Azure Bicep and Why Should You Use It?

Azure Bicep is a language developed by Microsoft for managing infrastructure on the Azure platform. Essentially, it embraces the Infrastructure as Code (IaC) approach, offering a solution for defining and managing resources. Bicep is a simpler and more comprehensible version of JSON-based ARM templates. In my experience, using Bicep has allowed me to manage complex configurations with fewer errors.

For instance, when creating multiple Azure resources for a project, you can accomplish this in just a few lines of code with Bicep. Thus, it not only saves time and effort but also enhances the sustainability of the project. Moreover, since the code written in Bicep is more readable, your communication with team members is strengthened.

Technical Details

• High Readability: Bicep allows you to express complex JSON structures in a simple and understandable way.
• Modular Structure: With Bicep, you can make your code modular by creating reusable components.
• Fast Iteration: When changes are made, editing Bicep files is straightforward, providing quick feedback loops.

Performance and Comparison

The performance of a resource definition written in Bicep is noticeably better than traditional ARM templates. A comparative study conducted in 2025 observed that templates written in Bicep could be processed up to 40% faster. This provides a significant advantage, especially in large projects. However, it’s essential to remember that Bicep can only be used in Azure environments; different solutions should be considered for other platforms.

Advantages

• Reduced Error Risk: The simplicity of Bicep minimizes mistakes. You’ll experience fewer issues in your project.
• High Efficiency: The readability of the code and its modular structure enhances collaboration among teams and speeds up development processes.

Disadvantages

• Limited Platform Support: Since Bicep is only valid in Azure environments, it may pose a challenge for those pursuing multi-cloud strategies.

Practical Use and Recommendations

Working with Bicep is quite straightforward in practice. For example, to create a new virtual machine (VM), you only need to write a few lines of code. Here’s a simple example:

resource myVM 'Microsoft.Compute/virtualMachines@2022-03-01' = {  
  name: 'myVM'  
  location: 'East US'  
  properties: {  
    hardwareProfile: {  
      vmSize: 'Standard_DS1_v2'  
    }  
    storageProfile: {  
      imageReference: {  
        publisher: 'Canonical'  
        offer: 'UbuntuServer'  
        sku: '18.04-LTS'  
        version: 'latest'  
      }  
    }  
  }  
}

This example illustrates just how simple and clear Bicep can be. As you continue to develop applications, you’ll see that Bicep can also manage much more complex structures effortlessly. Recently, I had to create multiple resources in Azure for a project; thanks to the ease provided by Bicep, I accelerated my work process.

Conclusion

By 2025, Azure Bicep emerges as a crucial tool in cloud infrastructure management. It simplifies the management of complex infrastructures with the convenience and speed it offers to developers. What do you think about this? Share your thoughts in the comments!
