AWS EC2 is a virtual computing environment (known as instances) to develop and deploy applications. To create an EC2 instance in AWS, we need an active Amazon Web Services account.
\nFirst, let's login into our AWS account. Once login, we will land on the Management Console page, we can see all the AWS services.
\nThere is a drop-down on the top left corner, which is one more option to search and browse all the services provided by AWS. You can find EC2 under the Compute category.
There is a button Launch Instance to create a new instance in the selected region on the dashboard's bottom section.
After clicking the Launch button, we need to select the Amazon Machine Image (AMI) it includes the operating system and applications required to launch an instance. Here we will select the Ubuntu Server 20.04 LTS as shown in the below snapshot.
\nWe can increase or decrease the size of instance storage while creating it; the free tier is eligible upto 30GB; if you need more storage, it will be billed according to Elastic Block Store (EBS) Pricing
\nOn the next screen, we can add tags to our instance and storage; these tags are key-value pair which are very useful to add properties to our resources, especially when we have multiple instances.
\nWe can define the firewall rules in a security group attached to our instance. With the help of these rules, we can control the traffic to our instance.
\nOnce we are done with firewall rules, we can review the complete detail of our new instance on a single page, and here we can click Launch button to launch the instance.
When we click Launch, it will open a pop-up that will require you to select a pre-existing public-private key-pair or create one to connect to our instance securely. Once you select/download the key, you will be able to launch the instance.
It will take approximately 5-10 min to launch the instance. Once launched, You can see the list of your running instances by clicking on the Instances button on the left menu.
