Learn how to create a Terraform module for setting up multiple Droplets behind a Load Balancer. Use the `for_each` and `count` features of HCL to deploy multiple instances. Improve infrastructure management and scalability with Terraform.
Terraform modules encapsulate distinct logical components of your infrastructure by grouping their resources together. In this tutorial, you’ll create a Terraform module that will set up multiple Droplets behind a Load Balancer for redundancy. You’ll also use the for_each and count looping features of the Hashicorp Configuration Language (HCL) to deploy multiple customized instances of the module at the same time.
Infrastructure as a Service (IaaS) is the on-demand delivery of computing infrastructure over the internet, including operating systems, networking, storage, and other infrastructural components.
The key to successful complex infrastructures, outlined in 10 minutes.
One of the main benefits of Infrastructure as Code is reusing parts of the defined infrastructure. In this tutorial, we’ll consider some of the ways of defining and reusing code in Terraform projects. You’ll reference modules from the Terraform Registry, separate development and production environments using modules, learn about templates and how they are used, and how to specify resource dependencies explicitly using the depends_on meta argument.
Hashicorp Configuration Language (HCL), which Terraform uses, like other programming languages provides a few different types of loops. In this article, we’ll review the data structures HCL provides, its looping features for resources (the count key, for_each, and for), writing conditionals to handle known and unknown values, as well as explicitly specifying dependency relationships between resources.

Join Kim as she compares and contrasts Terraform and Pulumi, demonstrates how to create a the cloud provider Webserver with Terraform and then Pulumi, and talks through the benefits and drawbacks of each project.
