Over the years, many concepts were introduced in the IT space, and many of them will integrate and build the next technological path for the next century. For example, cloud providers and disruptive changes in migration and visual infrastructure to large cloud data centers around the world, bringing significant benefits such as:
- Reduced IT costs
- Scalability
- Business Continuity
- Effective Collaboration
- Data Security
- Disaster Recovery
Terraform
Terraform is an open-source infrastructure as a code software tool created by HashiCorp. It enables users to define and provision a datacenter infrastructure using a high-level configuration language known as Hashicorp Configuration Language, or optionally JSON.
Installing Terraform is very easy in Linux and Mac, although in Windows there are some issues, so we recommend using a Unix system running in a Docker container or in Vagrant.
The installation tutorial can be found in the next provided link:
How does Terraform work?
Terraform creates and manages applications on cloud platforms and other applications through a programming interface (APIs). Providers allow Terraform to run on almost any platform or service with an accessible API.
HashiCorp and the Terraform community have already registered more than 1700 providers to manage thousands of different types of services and services, and this number continues to grow. You can find all of the publicly available providers in the Terraform Registry, including Amazon Web Services (AWS), Azure, Google Cloud Platform (GCP), Kubernetes, Helm, GitHub, Splunk, i -DataDog, and many more others.
Terraform’s basic workflow has three phases:
- Write: Describes resources, which can be available to most cloud providers and services. For example, you could create a configuration to run an application on virtual machines on a Virtual Private Cloud (VPC) network with security teams and load balancing.
- Application: Terraform creates an application that defines the infrastructure that will create, update, or destroy it based on existing infrastructure and your configuration.
- Apply: After approval, Terraform performs the proposed functions in their respective order, respecting any reliance on the application. For example, if you update VPC properties and change the number of virtual machines in that VPC, Terraform will re-create the VPC before measuring the virtual machines.
Manage any infrastructure
Find multi-platform providers and services already used in Terraform Registration. You can also write your own. Terraform takes a more consistent approach to infrastructure, reducing the complexity of upgrading or refining your resources and infrastructure.
Track your infrastructure
Terraform develops a program and tells you to get your permission before upgrading your infrastructure. It also tracks your actual infrastructure in a provincial file, which serves as a true source of your location. Terraform uses a provincial file to determine the changes you will make to your infrastructure to suit your configuration.
Change the changes
Terraform configuration files declare, which means they define the end state of your infrastructure. You do not need to write step-by-step instructions to create apps because Terraform has a basic concept. Terraform creates an app graph to determine app dependencies and create or modify non-dependable applications accordingly. This allows Terraform to provide the right services.
Set up configuration
Terraform supports reusable configuration components called modules that define adjustable clusters of infrastructure, time-saving and best practices. You can use the modules that are publicly available in the Terraform Registry or write your own.
So I hope this was very helpful and if you have any doubts or any questions you can write them down in the comment section below and I will try to answer you as soon as I can.
