10. Lab - Launch an EC2 instance

# Virtual Servers in the Cloud

In this hands-on exercise, you will launch a virtual server in the cloud within a secure network. You will also manage additional storage options for your server.

Prerequisites:

• AWS Account

Topics Covered:

By the end of this lab, you will be able to:

• Launch a secure EC2 (Elastic Cloud Compute) instance within a VPC (Virtual Private Cloud)
• Manage an EBS volume

Steps:

1. Access VPC service from AWS Management Console
   • On the AWS Management Console page, type vpc in the Find Services box and then select VPC.
   • Click the Launch VPC Wizard button and select VPC with a Single Public Subnet.
     Important: In the VPC Name text box, enter a name for the VPC, and then select the first AZ from the Availability Zone dropdown. Leave everything else as the defaults.
   • Select Create VPC button.
   • You should see the VPC Successfully Created page, click the OK button in the far right.
     Important: You should see a table that lists all of the VPCs, make a note of the one just created.
2. Launch an EC2 instance
   • Navigate to the EC2 console page, by clicking on Services in the upper left-hand menu. Type EC2 in the text box and click on EC2 found in the search results.
   • On the EC2 Dashboard page, click on Instances in the left-hand navigation.
   • Click Launch Instance.
   • Select the Amazon Linux 2 AMI (HVM), SSD Volume Type Amazon Machine Image (AMI).
     Important: You are free to choose a different AMI, but to avoid excessive charges, pick one that says, Free Tier Eligible.
   • For the Instance Type, select the free-tier instance type of t2.micro.
   • Click on Next: Configure Instance Details.
   • Enter the 1 for the Number of Instances.
   • For Purchasing option, leave unchecked.
   • For Network, select the VPC that was created in the previous step, and then select the subnet in to which to launch the instance.
   • Keep the other default settings on this page as is.
3. Attach an EBS volume
   • Click on Next: Add Storage to attach an EBS volume.
     Important: Here we already see there is a root volume (or device) attached to your instance, this is an EBS volume. We are going to add additional storage.
   • To attach additional storage, click on Add New Volume.
   • Select Delete on Termination and keep the other default settings.
   • Click Review and Launch.
   • Click Launch Instances.
   • Generate and download a new key pair and then launch the instance.
     Important: This will allow you to SSH into your instance from your local machine. This is a one-time process, so generate and download the new key pair now.
   • The launch will take a couple of minutes, select View Instances during the wait.
   • Check the instance state, it should say running.

Congratulations! You’ve launched your first virtual server in the cloud.

4. Cleanup & Disable EC2 Instance To avoid recurring charges for leaving an instance running, let’s disable the EC2 instance and terminate the VPC
   • From the EC2 Dashboard, select the instance just created, click Actions, then Instance State, and then select Terminate.
   • From the VPC Dashboard, select the VPC just created, click Actions, then Delete VPC.
