Running your First Terraform Program on AWS

Run Your First Terraform Program on AWS Terraform is an open-source infrastructure as code tool that allows you to build, change, and manage infrastructure in a consistent and repeatable manner using simple configuration files.  If you’re new to Terraform and looking to leverage its power for managing infrastructure on AWS, this guide is for you. Terraform on AWS is the Infrastructure as Code (IaC) tool, simplifies cloud resource provisioning, allowing you to automate and manage infrastructure efficiently. Let’s dive into how to run your first Terraform program on AWS. 1. Prerequisites 1.1 AWS Account Set up an AWS account at aws.amazon.com 1.2 Terraform Installation  Download and install Terraform 1.3 Visual Studio Code Installation Install Visual Studio Code (VS Code). Install the HashiCorp Terraform extension in VS Code for syntax support and code completion.  After Installing the extension, Set Up the Project Directory. 1.4 Set Up the Project Directory Create a new folder for your Terraform project files. Inside this folder, create a new file named main.tf Now, go to AWS Terraform Provider : Please navigate to the Provider section to obtain the base configuration code. Copy this code and paste it into your main.tf file for use in your Terraform project. Here is the Code, Terraform provider  Copy this code and paste it in main.tfterraform {required_providers {aws = {source = “hashicorp/aws”version = “5.75.1”}}}provider “aws” {# Configuration options} Copy this code and paste it in main.tf To Configure the aws into terraform, go terminal type the following commands   Type aws configure and give enter : After applying commands, it will ask you to enter the aws access key id   To get the Access ID, go to AWS console and go to the Security Credentials. Go to Create Access key and create the key After creating, you will get the Access key and Secret Access key Copy the Access key and paste it in the terminal After entering the access and secret keys, it will prompt you for the region and output format. Leave it as it is and press Enter.   Now we should run our code. To run the resources, type the following commands: terraform init The terraform init command initializes your working directory by downloading provider plugins, setting up backend configuration, loading modules, and preparing Terraform to manage infrastructure based on your configuration files.Before we move on  to next step, we will add one IAM user using terraform. Go to the aws terraform provider and search IAM. You will get the code to create IAM using terraform. Here is the code, aws_iam_user Copy the code and paste it in our main.tf file provider “aws” {region = “us-east-1” # Change to your desired AWS region}resource “aws_iam_user” “example_user” {name = “example-user” # Define the IAM user name} Here you can add any name and any region to create IAM Users Now give the command called terraform plan The terraform plan command previews changes Terraform will make to align the actual infrastructure with your configuration, and give the blue print like structure.     Now follow the command called terraform apply The terraform apply command executes the planned changes, creating, updating and resources to match your configuration   Give yes to perform actions . You have successfully initialized your first Terraform code configuration in AWS. To check the IAM user, go to the aws console and search iam and go to users The user was successfully added   Now the last command called terraform destroy  Give yes to make destroy all resources. The terraform destroy command removes all resources managed by Terraform in your configuration, effectively deleting the infrastructure. To check, go to the aws console and go to the IAM Users Here there is no resource to display, because the resource was destroyed using terraform   Thus the users to display.

Which of the below mentioned options is not available when an instance is launched by Auto Scaling with EC2 Classic?                 A. Public IP                 B. Elastic IP                C. Private DNS                D. Private IP   Answer: B Explanation:Auto Scaling supports both EC2 classic and EC2-VPC. When an instance is launched as a part ofEC2 classic, it will have the public IP and DNS as well as the private IP and DNS. Click to know answer Hide 2. You have been given a scope to deploy some AWS infrastructure for a large organization. The requirements are that you will have a lot of EC2 instances but may need to add more when the average utilization of your Amazon EC2 fileet is high and conversely remove them when CPU utilization is low. Which AWS services would be best to use to accomplish this?                 A. Auto Scaling, Amazon CIoudWatch and AWS Elastic Beanstalk                B. Auto Scaling, Amazon CIoudWatch and Elastic Load Balancing.                C. Amazon CIoudFront, Amazon CIoudWatch and Elastic Load                                                Balancing.                D. AWS Elastic Beanstalk , Amazon CIoudWatch and Elastic Load                                            Balancing. Answer: B Explanation:Auto Scaling enables you to follow the demand curve for your applications closely, reducing the need to manually provision Amazon EC2 capacity in advance. For example, you can set a condition to add new Amazon EC2 instances in increments to the Auto Scaling group when the average utilization of your Amazon EC2 fileet is high; and similarly, you can set a condition to remove instances in the same increments when CPU utilization is low. If you have predictable load changes, you can set a schedule through Auto Scaling to plan your scaling actMties. You can use Amazon CIoudWatch to send alarms to trigger scaling actMties and Elastic Load Balancing to help distribute traffic to your instances within Auto Scaling groups. Auto Scaling enables you to run your Amazon EC2 fileet at optimal utilization. Click to know answer Hide 3. You are building infrastructure for a data warehousing solution and an extra request has come through that there will be a lot of business reporting queries running all the time and you are not sure if your current DB instance will be able to handle it. What would be the best solution for this?                    A. DB Parameter Groups                   B. Read Replicas                   C. Multi-AZ DB Instance deployment                   D. Database Snapshots Answer: B Explanation:Read Replicas make it easy to take advantage of MySQL’s built-in replication functionality to elastically scale out beyond the capacity constraints of a single DB Instance for read-heavy database workloads. There are a variety of scenarios where deploying one or more Read Replicas for a given source DB Instance may make sense. Common reasons for deploying a Read Replica include:Scaling beyond the compute or I/O capacity of a single DB Instance for read-heavy database workloads. This excess read traffic can be directed to one or more Read Replicas. Serving read traffic while the source DB Instance is unavailable. If your source DB Instance cannot take I/O requests (e.g. due to I/O suspension for backups or scheduled maintenance), you can direct read traffic to your Read Replica(s). For this use case, keep in mind that the data on the Read Replica may be “stale” since the source DB Instance is unavailable. Business reporting or data warehousing scenarios; you may want business reporting queries to run against a Read Replica, rather than your primary, production DB Instance. Click to know answer Hide 4. In DynamoDB, could you use IAM to grant access to Amazon DynamoDB resources and API actions?                 A. In DynamoDB there is no need to grant access                B. Depended to the type of access                C. No                D. Yes Answer: D Explanation:Amazon DynamoDB integrates with AWS Identity and Access Management (IAM). You can use AWS IAM togrant access to Amazon DynamoDB resources and API actions. To do this, you first write an AWS IAMpolicy, which is a document that explicitly lists the permissions you want to grant. You then attach that policyto an AWS IAM user or role.

Test your skills 1. A user wants to use an EBS-backed Amazon EC2 instance for a temporary job. Based on the input data, the job is most likely  to finish within a week. Which of the following steps should be followed to terminate the instance automatically once the job is finished?                   A. Configure the EC2 instance with a stop instance to terminate it.                  B. Configure the EC2 instance with ELB to terminate the instance when it                              remains idle.                  C. Configure the CIoudWatch alarm on the instance that should perform the                          termination action once the instance is idle.                  D. Configure the Auto Scaling schedule actMty that terminates the instance                            after 7 days. Answer: C Explanation:Auto Scaling can start and stop the instance at a pre-defined time. Here, the total running time is unknown.Thus, the user has to use the CIoudWatch alarm, which monitors the CPU utilization. The user can create an alarm that is triggered when the average CPU utilization percentage has been lower than 10 percent for 24 hours, signaling that it is idle and no longer in use. When the utilization is below the threshold limit, it will terminate the instance as a part of the instance action. Click to know answer Hide 2. Which of the following is true of Amazon EC2 security group?                    A. You can modify the outbound rules for EC2-Classic.                   B. You can modify the rules for a security group only if the security group                             controls the traffic for just one instance.                   C. You can modify the rules for a security group only when a new instance is                         created.                   D. You can modify the rules for a security group at any time.   Answer: D Explanation:A security group acts as a virtual firewall that controls the traffic for one or more instances. When you launch an instance, you associate one or more security groups with the instance. You add rules to each security group that allow traffic to or from its associated instances. You can modify the rules for a security group at any time; the new rules are automatically applied to all instances that are associated with the security group. Click to know answer Hide 3. An Elastic IP address (EIP) is a static IP address designed for dynamic cloud computing. With an EIP, you can mask the failure of an instance or software by rapidly remapping the address to another instance in your account. Your EIP is associated with your AWS account, not a particular EC2 instance, and it remains associated with your account until you choose to explicitly release it. By default how many EIPs is each AWS account limited to on a per region basis?                    A. 1                   B. 5                   C. Unlimited                   D. 10 Answer: B Explanation:By default, all AWS accounts are limited to 5 Elastic IP addresses per region for each AWS account, because public (IPv4) Internet addresses are a scarce public resource. AWS strongly encourages you to use an EIP primarily for load balancing use cases, and use DNS hostnames for all other inter-node communication. If you feel your architecture warrants additional EIPs, you would need to complete the Amazon EC2 Elastic IP Address Request Form and give reasons as to your need for additional addresses.

Test your skills 1. A user wants to use an EBS-backed Amazon EC2 instance for a temporary job. Based on the input data, the job                  is most likely to finish within a week. Which of the following steps should be followed to terminate the instance                  automatically once the job is finished?                   A. Configure the EC2 instance with a stop instance to terminate it.                  B. Configure the EC2 instance with ELB to terminate the instance when it remains idle.                  C. Configure the CIoudWatch alarm on the instance that should perform the termination action once the                                         instance is idle.                  D. Configure the Auto Scaling schedule actMty that terminates the instance after 7 days. Answer: C Explanation:Auto Scaling can start and stop the instance at a pre-defined time. Here, the total running time is unknown.Thus, the user has to use the CIoudWatch alarm, which monitors the CPU utilization. The user can create an alarm that is triggered when the average CPU utilization percentage has been lower than 10 percent for 24 hours, signaling that it is idle and no longer in use. When the utilization is below the threshold limit, it will terminate the instance as a part of the instance action. Click to know answer Hide 2. Which of the following is true of Amazon EC2 security group?                    A. You can modify the outbound rules for EC2-Classic.                   B. You can modify the rules for a security group only if the security group controls the traffic for just                                               one instance.                   C. You can modify the rules for a security group only when a new instance is created.                   D. You can modify the rules for a security group at any time. Answer: D Explanation:A security group acts as a virtual firewall that controls the traffic for one or more instances. When you launch an instance, you associate one or more security groups with the instance. You add rules to each security group that allow traffic to or from its associated instances. You can modify the rules for a security group at any time; the new rules are automatically applied to all instances that are associated with the security group. Click to know answer Hide 3.
