12 Learning Resources for Terraform Certification
Terraform is an efficient tool to help organizations develop similar infrastructure across various cloud and on-premise platforms with security.
That said, the growth of cloud infrastructure has brought high demands for related technologies as well.
So, learning Terraform can offer cloud engineers bigger opportunities in their professional lives while helping them upskill themselves.
There is also a certification exam – Terraform Certified Associate – that you can clear to land more opportunities. And thankfully, plenty of resources are available, both free and paid, so you can learn and appear for the exam and pass it with good scores.
Let’s talk about Terraform in detail, a few things about the exam, and some of the best resources available.
What is Terraform?
Terraform is an open-source infrastructure-as-a-code (IaC) software tool developed by HashiCorp in 2014. It offers a consistent command-level interface (CLI) workflow to help you manage multiple cloud services. It also codifies cloud APIs into a declarative configuration file.
Terraform was written in Go and supported operating systems, including Windows, macOS, Linux, FreeBSD, OpenBSD, and Solaris. It supports multiple cloud infrastructure providers like AWS, Azure, Google Cloud Platform, IBM Cloud, Oracle Cloud, DigitalOcean, VMware, OpenStack, and Yandex. cloud.
Users provide and define data center infrastructure with the help of HashiCorp Configuration Language (HCL) – a declarative configuration language. It offers concise resource descriptions using expressions, arguments, and blocks. However, there is also an option to use JSON instead.
Terraform can manage external resources like private and public cloud infrastructure, SaaS, PaaS, network appliances, etc., with providers. In addition, HashiCorp has maintained a long list of all the official providers. You can either declare resources or call data sources to interact with Terraform providers.
You can use Terraform in the following way:
- Write code using HCL or JSON
- Plan by running the code and check whether it’s suitable for your needs before changing or provisioning the infrastructure
- Apply the final changes to multiple providers and attain the desired configuration state.
Features of Terraform
- Declarative configuration files: You can define infrastructure as code and manage the entire lifecycle. It will help you create resources, manage existing resources, and destroy resources you no longer require.
- Installable Module: You can install partner or community modules automatically from the registry using terraform init.
- Predict and plan changes: Terraforms lets you modify infrastructure predictably and safely by separating the planning and application and using mapped dependencies.
- Dependency graphing: You can easily create terraform plan and refresh state using config dependency graphing
- State management: Map real-world resources to configurations, improve performance, and track metadata for large infrastructures.
- Supports multiple languages: You can provision infrastructure in Java, Go, C#, Python, TypeScript, and other programming languages with HCL modules and 1000+ Terraform providers like AWS, GCP, Azure, Oracle, VMware, Datadog, etc.
Uses cases of Terraform
- Multi-cloud deployment: As Terraform supports multiple cloud services, you can deploy your infrastructure using a variety of cloud providers
- Scalable applications: You can easily scale up/down the resources you require, which helps you create scalable, multi-tier applications.
- Resource management: You can manage resources smoothly across all the supported cloud services, including public and private, SaaS, PaaS, and network appliances.
- Software-Defined Networking (SDN): Terraform is highly readable, making it easier to codify an SDN’s configuration.
- Build testing environments: You can use modules to create a temporary test environment to test your code before using it for production,
- Resource scheduling: You can use Terraform modules to start and stop resources on AWS while letting Kubernetes schedule the Docker containers.
- Clusters: Using registries allows you to discover pre-packaged configurations quickly and use them to meet your needs.
Benefits of using Terraform
Increased automation and reduced errors
Terraform lets you define, configure, and provision resources on cloud and on-premises efficiently using templated configuration files. As a result, your expenses reduce as you can create and dispose of environments with preset configs. Automation also reduces human errors to improve the entire operation than manual ways.

You can manage resources across 300+ cloud services and providers with just one Terraform workflow. Ultimately, it results in a simpler orchestration process while aiding in creating multi-cloud infrastructures with ease. In addition, you can also build reproducible infrastructure using the same configuration for staging, testing, and production.
As Terraform is open-source, it has garnered a lot of users across the globe who can use the code and use it according to their needs. This has built an extensive user base with skilled professionals who constantly develop and use the tool. You can join this strong community and learn and seek support from professionals regarding the tool, its plugins, extensions, etc.
Other benefits include easy portability to other providers, easy-to-understand HCL language, immutable infrastructure, and more.
Is Terraform a good career option?
Given this widespread use of Terraform, it has a good career option. Organizations that are spread across the globe need robust technologies to manage their resources across different cloud and on-premise environments and want to orchestrate similar infrastructure with minor variations can enjoy using Terraform.
