Terraform enables you to safely and predictably create, change, and improve
production infrastructure. It is an open source tool that codifies APIs into
declarative configuration files that can be shared amongst team members,
treated as code, edited, reviewed, and versioned.

<h2>Infrastructure as Code</h2>

Define infrastructure as code to increase operator productivity
and transparency.

<h3>Collaborate &amp; share</h3>
<p>Terraform configuration can be stored in version control,
shared, and collaborated on by teams of operators.</p>
<h3>Evolve your infrastructure</h3>
<p>Track the complete history of infrastructure versions.</p>
<h3>Automation friendly</h3>
<p>If it can be codified, it can be automated.</p>

<h2>One Safe Workflow Across Providers</h2>

<h3>Map Resource Dependencies</h3>
<p>
Understand how a minor change could have potential cascading effects
across an infrastructure before executing that change. Terraform
builds a dependency graph from the configurations, and walks this
graph to generate plans, refresh state, and more.
</p>
</div>
<div class="col-sm-4">
<h3>Separation of Plan &amp; Apply</h3>
<p>
Separating plans and applies reduces mistakes and uncertainty at
scale. Plans show operators what would happen, applies execute
changes.
</p>
</div>
<div class="col-sm-4">
<h3>One Safe Workflow</h3>
<p>
Use Terraform to create resources across all major infrastructure
providers (AWS, GCP, Azure, OpenStack, VMware, and more).

<h3>Environment parity</h3>
<p>Use the same Terraform configuration to provision identical staging,
QA, and production environments.</p>
</div>
<div class="col-sm-4">
<h3>Shareable modules</h3>
<p>Common Terraform configurations can be packaged as modules and used
across teams and organizations.</p>
</div>
<div class="col-sm-4">
<h3>Combine multiple providers consistently</h3>
<p>Terraform allows you to effortlessly combine high-level system
providers. Launch a server from one cloud provider, add a DNS entry
with its IP with a different provider. Built-in dependency resolution
means things happen in the right order.</p>
