IaaS (Infrastructure-as-a-Service) is a cloud computing model that provides virtualized compute, networking, storage, and other basic physical infrastructure for your applications. Terraform is an open-source tool for fully automating IaaS deployments. It allows you to create, edit, and destroy servers on demand with simple configuration files. In this post we’ll be exploring how Terraform works in practice and highlighting some of its benefits over more traditional models like AWS CloudFormation or VMware vSphere Integrated Containers (VIC).
Automated IaaS deployment and management
Terraform is an open source tool developed by HashiCorp to manage infrastructure as code. It allows you to create, transform and destroy infrastructure resources in various cloud providers such as AWS, Google Cloud Platform (GCP), Azure and others.
Terraform modules are packages of reusable configuration files that can be used across multiple projects. They let you share state variables between different environments without having to manually copy them around every time you want to run a new project on the same cloud provider or platform.
Terraform providers are third party libraries that give access through the API of your chosen cloud provider so Terraform can communicate with it directly without having any knowledge about how each individual service works internally (for example: creating VMs).
The Basics of Terraform
Terraform is an open source tool for building, changing, and versioning infrastructure safely and efficiently. Terraform can manage both public and private cloud resources, as well as traditional virtualization technologies.
The main benefit of using Terraform is its ability to create reusable code that you can use across different teams or projects. This reduces the amount of time spent writing infrastructure code from scratch every time you need it by making sure everyone uses the same standard conventions for describing how their systems should work together
Modules in the Real World
Modules are a way to reuse code. They can be shared with other people, used in multiple environments and even by multiple teams within your organization.
Let’s take an example from our own experience: We use Terraform modules when we want to add new resources to our infrastructure or update existing ones. We write these modules using the Go programming language, which allows us to write code that is both efficient and easy-to-read (and thus maintain).
Terraform is an open-source tool for fully automating infrastructure deployments.
Terraform is an open-source tool for fully automating infrastructure deployments. It can be used to provision virtual machines, networks, and other resources on any cloud or static hosting provider. Terraform uses a declarative configuration syntax to describe your entire infrastructure as code (IaC), which allows you to easily change and manage your deployment.
The goal of this tutorial is to help you get started with Terraform by deploying a Linux machine using DigitalOcean’s API v2 endpoints and public images running Ubuntu 16.04 LTS Xenial Xerus operating system with Apache web server installed on top of it.
By leveraging Terraform’s modules, you can build and deploy your infrastructure in a repeatable, automated way. The best part about this tool is that it doesn’t require any additional software or hardware beyond what your cloud provider already offers, making it a great option for companies looking to build an IaaS solution from scratch or migrate from existing platforms like AWS or Google Cloud Platform (GCP).
