Provisioning tool

Q: How deeply does Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform cover provisioning tool?

Defines providers, resource dependencies, and dry runs, but does not detail tool-specific implementation design.

As explained in Infrastructure as Code, Patterns and Practices: With examples in Python and Terraform

Software that creates and prepares infrastructure resources and manages their infrastructure-level dependencies.

When a network change may affect a server, a provisioning tool reveals the dependency before applying it. It creates and manages infrastructure resources for a provider such as a public cloud, data center, or hosted monitoring service, and can preview expected changes through a dry run. section 1.5.2

Use provisioning tools to manage infrastructure relationships while keeping neighboring responsibilities distinct:

Select a provider-specific tool, such as AWS CloudFormation, or a multiprovider tool, such as Terraform or Pulumi. section 1.5.2
Keep configuration management focused on packages and server attributes; its integrations do not necessarily make it the best provisioning tool because dependency handling differs. section 1.5.3
Coordinate provisioning with image building: configure and test the server, capture a versioned image, then provision servers from that image. section 1.5.4

Previewing and refactoring infrastructure

A Terraform dry run can show that a network change may also change a dependent server. During refactoring, existing IAM resources can be imported, checked against separated configuration, and removed from the monolith’s state so one resource is not managed twice. section 1.5.2 section 10.2.1

Table 1.1 Examples of provisioning tools and providers (view table figure)

Tool	Provider
AWS CloudFormation	Amazon Web Services
Google Cloud Deployment Manager	Google Cloud Platform
Azure Resource Manager	Microsoft Azure
Bicep	Microsoft Azure
HashiCorp Terraform	Various (for a complete list, see www.terraform.io/docs/providers/index.html)
Pulumi	Various (for a complete list, see www.pulumi.com/docs/intro/cloud-providers/)
AWS Cloud Development Kit	Amazon Web Services
Kubernetes manifests	Kubernetes (container orchestrator)

Compare provisioning tools with their supported providers, including cloud-specific, multiprovider, and Kubernetes options. section 1.5.2
