Starting with Infrastructure as Code
Azure Bicep templates are an essential tool in simplifying your infrastructure code’s complexity. What is Infrastructure as code? Think of it as an easier-to-read instruction manual for your infrastructure or a process of automating your infrastructure provisioning. Virtual machines, websites, and databases are all deemed as infrastructure. Infrastructure as code is essential because it gives higher confidence to deployments when leveraging program language. Ultimately, development teams end up with much less human error because it limits the need for manual processes.
- Increase confidence in your deployments by reducing human error and increasing consistency and remote management
- Manage multiple environments by reusing artifacts across Dev, QA, and Production deployments
- More accessible to clients, with straightforward knowledge transfer
Infrastructure as Code Techniques
The two methods to use infrastructure code fall under imperative and declarative. Here’s how they differ:
Imperative (used by Azure)
- An ordered sequence of commands
- What the code should accomplish
- How to accomplish the task
- What the code should accomplish
- Not how it should be accomplished
Infrastructure as code is essential because it gives higher confidence to deployments when leveraging program language.
Templatizing in the Cloud
Many teams have adopted agile development approaches as a result of the transition to the cloud. These groups iterate frequently, and they must be able to deploy their solutions to the cloud regularly and have confidence in their infrastructure. The distinction between operations and development has vanished since infrastructure has become a part of the iterative process. Teams now must use a single strategy to manage infrastructure and application code.
You can automate deployments and leverage the infrastructure as code methodology to meet these difficulties. Keep in mind, the infrastructure that must be installed is defined in code. Your infrastructure code is then incorporated into your project. Infrastructure code, like application code, is stored in a source repository and versioned.
Bicep, a modernized language, offers the same capabilities as ARM templates but with a syntax that’s much easier to use. Each Bicep file is automatically converted to an ARM template during deployment. If you’re considering infrastructure as code option, Bicep is highly recommended.
You define the infrastructure you wish to deploy to Azure in a Bicep file and then use that file throughout the development lifecycle to deploy your infrastructure repeatedly.
Bicep is essentially declarative domain-specific language (DSL) for deploying Azure resources. You define the infrastructure you wish to deploy to Azure in a Bicep file and then use that file throughout the development lifecycle to deploy your infrastructure repeatedly. Best of all, your resources will be deployed consistently.
Bicep has a simple syntax, reliable type safety, and code reuse support. For your Azure infrastructure-as-code solutions, Bicep provides a first-class authoring experience.
Benefits of Bicep
- Simpler syntax means reference parameters and variables are referenced directly using their symbolic names
- Modules break down complex template deployments into smaller module files and reference them in the main template
- Automatic dependency management detects dependencies between resources
- Type validation and IntelliSense uses VS Code and Visual Studio extensions for Validation and IntelliSense for all Azure resource-type API definitions
