Automating Infrastructure on AWS with Terraform for Interviews and Freelancing

📝 In this video, we learn how to use terraform to automate infrastructure on AWS.

🧱 Terraform is an infrastructure as code tool that allows us to create resources with clear code.

🔑 To get started, we need an AWS account, terraform installed, and access keys for authentication.

🔑 The first command to run when working with Terraform is 'terraform init' to initialize the working directory and connect with AWS.

💡 After successfully initializing, you can automate tasks using Terraform on the AWS platform by creating resources and running 'terraform plan' to see the changes before applying them.

🛠️ When using Terraform, it is important to understand the parameters and configurations for creating resources, such as VPC, subnets, security groups, and EC2 instances.

📌 Creating subnets and changing their names and CIDR blocks

📌 Adding internet gateway and defining routes in the route table

📌 Associating subnets with the route table for public internet connection

Terraform is considered one of the easiest devops tools if you have knowledge of AWS.

Learning the HCL syntax and practicing daily can boost confidence in using Terraform.

There are advanced features in Terraform, such as setting up CI/CD, that can be explored.

🎯 The video is about creating a Terraform project on AWS, using instance types, security groups, and load balancers.

💡 To save money, the recommended instance type is T2 micro, and a load balancer is mentioned but can be deleted after the project is completed.

🔒 Security groups and subnets are defined, and user data is used to run startup scripts to install software and set up a web page on Port 80.

📝 The video discusses how to create an application load balancer using Terraform and AWS services.

🔒 The load balancer can be configured as public or private and requires security groups and subnets.

⚙️ The load balancer needs to be attached to a target group and a listener to properly distribute traffic among instances.

🔑 The video discusses creating infrastructure on AWS using Terraform.

⚙️ The speaker explains the process of deploying instances, configuring load balancers, and integrating Ansible with Terraform.

💡 The project is a common one for DevOps engineers and involves automating the setup of instances, load balancers, and web applications.
