It has attributes such as Type, vCPU, Memory, Instance Storage, Network Performance etc. We can decide the type of instance based on our application requirement. AWS also provides some instances for the free tier.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"5Configure_instance_details\"><\/span><strong>5.Configure instance details<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.testleaf.com\/blog\/wp-content\/uploads\/2022\/08\/configure-instance-details.png\" alt=\"Step by Step Guide to Setup Amazon EC2 Instance\" width=\"1171\" height=\"629\" \/><br \/>\nHere, we can configure our instance details such as the number of instances to be created, purchasing options, placement group, and other network settings. We can also install the software we require our EC2 instance to have; this can be done by specifying the user data. The user data will run only once, i.e., at the first booting of the instance, where it performs all the operations specified in the user data.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"6Add_Storage\"><\/span><strong>6.Add Storage<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.testleaf.com\/blog\/wp-content\/uploads\/2022\/08\/Add-Storage.png\" alt=\"Step by Step Guide to Setup Amazon EC2 Instance\" width=\"1252\" height=\"254\" \/><br \/>\nThe next step is to add additional storage to our instance; our instance comes with a default root <a href=\"https:\/\/docs.aws.amazon.com\/ebs\/latest\/userguide\/ebs-volumes.html\">EBS volume<\/a>. If the user wants more storage, they can create a new EBS volume of any type by clicking on add storage.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"7Add_tags\"><\/span><strong>7.Add tags<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.testleaf.com\/blog\/wp-content\/uploads\/2022\/08\/Add-tags..png\" alt=\"Step by Step Guide to Setup Amazon EC2 Instance\" width=\"1034\" height=\"280\" \/>The next step is to add tags, and this is optional.

It is the firewall between the EC2 and the internet. We can create and assign a new security group to the EC2 instance or attach an existing security group. This is used to specify who will have access to our EC2 instance. A default SSH rule will be specified while creating it; we can add additional rules such as <a href=\"https:\/\/www.testleaf.com\/blog\/most-common-used-http-response-status-codes\/\">HTTP<\/a> or HTTPS and set the source IP address to allow access. (we can also attach an existing security group instead of the IP addresses).<\/p>\n<p><strong>9.Review and launch instance<\/strong><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.testleaf.com\/blog\/wp-content\/uploads\/2022\/08\/Review-and-launch-instance.png\" alt=\"Step by Step Guide to Setup Amazon EC2 Instance\" width=\"1237\" height=\"413\" \/>All the details entered in the previous steps will be displayed here; you can review and make any changes before you launch your instance.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"10Createchoose_a_key_pair\"><\/span><strong>10.Create\/choose a key pair<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.testleaf.com\/blog\/wp-content\/uploads\/2022\/08\/Createchoose-a-key-pair.png\" alt=\"Step by Step Guide to Setup Amazon EC2 Instance\" width=\"1322\" height=\"498\" \/><br \/>\nThe last step is to create or choose an existing key pair; the key pair combines a public key and a private key file. The <a href=\"https:\/\/www.testleaf.com\/blog\/5-steps-to-become-a-certified-aws-cloud-practitioner\/\">AWS<\/a> stores the public key, and the user will store the private key file; the private key file will have the extension &#8220;.pem.&#8221; For Windows AMIs, this file is required to obtain the password used to log on to the EC2 instance. For Linux AMIs, this file is required to securely SSH into the EC2 instance.<br \/>\nOn clicking the launch instance, our instance will be created.<\/p>\n<h2 data-start=\"3043\" data-end=\"3088\"><span class=\"ez-toc-section\" id=\"Connect_to_your_EC2_instance_SSHRDP\"><\/span><strong>Connect to your EC2 instance (SSH\/RDP)<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p data-start=\"3089\" data-end=\"3243\">This is the biggest missing intent gap.
