Learn to automate your infrastructure using IaC (Infrastructure as Code) using
Terraform in this course which covers its fundamental and advanced features.


The course includes hands-on labs and a Quick Win Lab to help you learn how
Terraform is able to quickly move resources to the cloud. It will also help you
develop the necessary skills to pass HashiCorp Certified Terraform Associate
Examination.


Introduction to Terraform


Terraform, a cloud-based automation tool allows you to define and manage
infrastructure without having to use an interface. Terraform's comprehensive
public registry, that includes examples and documentation for the most common
scenarios of cloud environment provisioning can make managing cloud environments
a breeze.


This course will introduce the fundamentals of using Terraform to configure and
deploy infrastructure. The course will feature video-free assignments,
self-paced learning experience, and hands-on practice using AWS resources.


Terraform's configuration file is the foundation of Terraform. It functions as a
summary of how the infrastructure of your system will appear like when it comes
to conclusion. The declarative statement that you define by yourself can be made
individually or in a group with multiple files.


After you've made a configuration, Terraform creates an execution plan and seeks
your approval before initiating modifications to your infrastructure. This gives
you the opportunity to examine any changes made before they go live.


Configuration Management


Configuration Management is a crucial component of IT Infrastructure. It allows
the monitoring of changes made to an application, or infrastructure over the
course of its existence.


In the last couple of years, several configuration management tools have been
developed, such as Ansible. Chef, Puppet, and SaltStack.


Terraform is an Infrastructure as Code (IAC) tool used to automate cloud
resource management and deployment. With  terraform training london  in resource
management that is repeatable and reliable, Terraform allows users to quickly
create and deploy reusable infrastructure architectures.


Terraform offers users a formal language to define the desired final state. It
then determines the best way to get to this goal. Terraform is a system that
assembles and reuses complex resources with modules. Users are able to define
these modules or source them via Terraform Registry's central repository.





Deployment


Terraform is a tool that makes creating, managing, and deploying
infrastructure-as-code easier. It is able to handle hybrid and multi-cloud
scenarios.


Terraform is a fast-growing infrastructure to test, production as well as
quality assurance settings. This allows you to save money while maintaining
uniformity across various applications.


Terraform configuration files are able to be changed at any time. The files also
list the plug-ins, providers, and providers that are required to connect to a
cloud service.


Terraform helps to reduce the drift in configuration by comparing its
configuration files against each resource that it develops or modifies. it
ensures that the infrastructure is in line with what was specified in the config
file.


Terraform can support more than 100 cloud providers including AWS, Azure and GCP
- three of the most popular providers. Furthermore, custom-built providers can
be added.


Watching


Terraform provides an infrastructure-as-code approach for managing cloud
environments. This method makes writing configuration files simple which makes
management of version control simple.


Application-specific configurations can easily be moved between environments,
which allows the deployment of applications from development to hardening to
production. This also lets users quickly adapt to changing compute resource
requirements without needing to alter their entire infrastructure.


Dynatrace integration with Terraform lets developers have the possibility to
track code-level activity from within one CLI which gives them access to
dashboards and reports that can be used in conjunction with services or
containers as they become available.


In this case, we'll create a monitoring system to run NodePing tests on every
host on which NodePing is installed, and to alert us when one of them goes down.
While the setup isn't difficult but keeping it up-to-date and operational will
ensure that you won't be caught off guard by unexpected failure.
