One of the pioneers of this cloud revolution is Amazon Web Services (AWS) \u2014 a suite of cloud services offering everything from basic computing power to sophisticated machine learning capabilities. Among AWS&#8217;s offerings, Elastic Compute Cloud (EC2) provides scalable computing capacity in the cloud, making web-scale cloud computing easier for developers.<\/p>\n\n\n\n<p>When launching an EC2 instance, one of the options available is Amazon Linux. Here are two key benefits of using Amazon Linux:<\/p>\n\n\n\n<ol>\n<li><strong>Optimization for the AWS ecosystem:<\/strong> Amazon Linux is tailored for AWS. It integrates very well with AWS services and offers a lightweight, secure, and highly performant environment for applications.<\/li>\n<\/ol>\n\n\n\n<ol start=\"2\">\n<li><strong>Security and reliability:<\/strong> Amazon Web Services maintains and supports Amazon Linux, ensuring it receives necessary patches and updates, especially focusing on security and performance.<\/li>\n<\/ol>\n\n\n\n<p>Now, after you&#8217;ve chosen our distribution, the next step is deployment. Deployment is a crucial phase in the software development lifecycle. By deploying on a trusted platform like Amazon Linux on AWS, developers can ensure scalability, reliability, and performance.<\/p>\n\n\n\n<p>For this tutorial, we dive deep into deploying a Node.js application on Amazon Linux using Nginx as a reverse proxy.\u00a0<\/p>\n\n\n\n<figure class=\"image is-16by9\">\n<iframe class=\"has-ratio\" width=\"300\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/1ZYWAykk1MY?rel=0\" frameborder=\"0\" allow=\"accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen=\"\"><\/iframe>\n<\/figure>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"step1\">Step 1: Sign in to your AWS account<\/h2>\n\n\n\n<p>Before we proceed with our Amazon Linux setup, we need an AWS account.&nbsp;<\/p>\n\n\n\n<p>The first step, go to the URL <a href=\"https:\/\/aws.amazon.com\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/aws.amazon.com<\/a> and click to sign in to the console.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"96\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/1-1.png\" alt=\"screenshot\" class=\"wp-image-105039\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/1-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/1-1-300x56.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>Here you have two options whether you want to log in as a Root user or an IAM user:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"379\" height=\"512\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/2-1.png\" alt=\"screenshot\" class=\"wp-image-105040\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/2-1.png 379w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/2-1-222x300.png 222w\" sizes=\"(max-width: 379px) 100vw, 379px\" \/><\/figure>\n\n\n\n<p>Consider selecting a user login that aligns with your account settings and optimal security; it&#8217;s advisable to use an account with minimal access rights.<\/p>\n\n\n\n<p>If you\u2019re not yet an AWS account holder, feel free to sign up; many new users qualify for complimentary access to select services under the AWS free tier.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"step2\">Step 2: Create a new AWS EC2 instance<\/h2>\n\n\n\n<p>After signing in to your AWS account, use the search bar to type &#8220;EC2.&#8221; This will take you to the main page where you can set up and manage your resources.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"221\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/3-1.png\" alt=\"screenshot\" class=\"wp-image-105041\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/3-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/3-1-300x129.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>Next, under Instances, you can select the option &#8220;<strong>Launch instances<\/strong>.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"217\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/4-1.png\" alt=\"screenshot\" class=\"wp-image-105042\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/4-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/4-1-300x127.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>On the next page, you have the opportunity to choose extra settings, including the instance&#8217;s Name, Application, and OS Images. For our instance, we will go with the standard choice, which is Amazon Linux.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"417\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/5-1.png\" alt=\"screenshot\" class=\"wp-image-105043\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/5-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/5-1-300x244.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>An Amazon Machine Image, or AMI, is a preset virtual machine image with everything needed to launch a working AWS cloud instance. Think of it as a template for creating virtual servers, also known as EC2 (Elastic Compute Cloud) instances, making it simpler to duplicate server setups.<\/p>\n\n\n\n<p>&#8220;Free Tier eligible&#8221; implies that AWS permits users to access a certain amount of its services for free, either for a limited time or until you hit specific usage caps. This is a great way for new users to explore AWS, but it\u2019s important to keep an eye on your use and understand the limits to prevent any surprise costs when the free offerings are surpassed.<\/p>\n\n\n\n<p>As we continue to scroll down, we can choose our instance type. Amazon Linux requires a minimum of 512MB RAM and 1 CPU core. For test purposes, selecting the t2.micro instance would be a good fit since it falls under AWS\u2019s Free Tier.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"175\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/6-1.png\" alt=\"screenshot\" class=\"wp-image-105044\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/6-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/6-1-300x103.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>If your project and instance need to be ready for production use, you should opt for instances that offer more RAM and CPU capacity. You can do this by selecting from the available options in the dropdown menu.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"step3\">Step 3: Configure your EC2 instance<\/h2>\n\n\n\n<p>We will continue with our setup process by configuring the security group for our instance.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"145\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/7-1.png\" alt=\"screenshot\" class=\"wp-image-105045\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/7-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/7-1-300x85.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>Establishing a new security group for your EC2 instance is a critical step toward ensuring optimal security within AWS. This practice enables you to set up and apply tailored network access rules, stick to the least privilege principle, and enhance the isolation and overall security of your EC2 instances.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"498\" height=\"512\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/8-1.png\" alt=\"screenshot\" class=\"wp-image-105046\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/8-1.png 498w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/8-1-292x300.png 292w\" sizes=\"(max-width: 498px) 100vw, 498px\" \/><\/figure>\n\n\n\n<p>Make sure to enter both the Key pair name and select the Key pair type, which could be RSA or ED25519.<\/p>\n\n\n\n<p>Both RSA and ED25519 are reliable choices for SSH key authentication. Your choice between them should be based on your security needs, compatibility requirements, and how much you trust newer cryptographic algorithms. Both options provide secure authentication for most situations when used properly. RSA is older, well-established, and works with a broad range of SSH servers and clients. ED25519, on the other hand, is an excellent option when security is paramount, and you don\u2019t need compatibility with older systems.<\/p>\n\n\n\n<p>Next, choose the Private key file format. You can pick between .pem format or .ppk if you&#8217;re using a Windows SSH client like PuTTy.<\/p>\n\n\n\n<p>For our purposes, we will go with the .pem format since we are using a terminal.<\/p>\n\n\n\n<p>Once everything is set, click &#8220;Create key pair&#8221; to generate your SSH key, and this will start a download through your browser. Note, AWS warns you to keep your private keys in a secure but reachable location on your computer.<\/p>\n\n\n\n<p>As we move forward with our setup, the next step is to configure our Network settings.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"357\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/9-1.png\" alt=\"screenshot\" class=\"wp-image-105047\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/9-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/9-1-300x209.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>For the initial setting, we aim to connect to our EC2 instance via SSH. However, instead of setting it to accept SSH traffic from &#8220;0.0.0.0\/0&#8221; (which opens the connection to any location), we should narrow it down to accept connections solely from trusted, specific IP addresses or ranges. This precaution minimizes the potential exposure of your SSH port on the internet, diminishing the chances of unauthorized access. You can specify the allowed IP ranges using CIDR notation, such as &#8220;192.168.1.0\/24.&#8221;<\/p>\n\n\n\n<p>Additionally, since our plan includes setting up an Nginx web server as a practical demonstration, be sure to select the option to &#8220;Allow HTTP traffic from the internet.&#8221;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"77\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/10-1.png\" alt=\"screenshot\" class=\"wp-image-105048\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/10-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/10-1-300x45.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>Next, we can select our storage options from the menu:<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"198\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/11-1.png\" alt=\"screenshot\" class=\"wp-image-105049\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/11-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/11-1-300x116.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>Here, we\u2019ve opted for a new storage volume of 8GB, classified as a general-purpose gp3 type. It\u2019s crucial to scale up the volume size to align with your needs for production use. Generally, gp3 EBS volumes stand out for their versatility, enhanced burst performance, and potential for cost-effectiveness per gigabyte when compared to gp2 volumes. Your choice between them should hinge on the particular I\/O requirements and performance expectations of your application, as well as any budgetary limits.<\/p>\n\n\n\n<p>Concluding our setup, we\u2019ll review all the chosen settings in the summary section and then move forward to initiate the instance launch.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"403\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/12-1.png\" alt=\"screenshot\" class=\"wp-image-105050\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/12-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/12-1-300x236.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>You will get the notification that the instance is successfully launched and you can return to your <strong>Instances<\/strong> list.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"149\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/13-2.png\" alt=\"screenshot\" class=\"wp-image-105051\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/13-2.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/13-2-300x87.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>After a short wait, typically with a fast provisioning time, you&#8217;ll be able to locate your instance in the list.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"260\" src=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/14-1.png\" alt=\"screenshot\" class=\"wp-image-105052\" srcset=\"https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/14-1.png 512w, https:\/\/jumpcloud.com\/wp-content\/uploads\/2024\/02\/14-1-300x152.png 300w\" sizes=\"(max-width: 512px) 100vw, 512px\" \/><\/figure>\n\n\n\n<p>The next step is to connect to the instance via SSH.

For security purposes, you need to modify the key&#8217;s permissions to ensure it&#8217;s not accessible to the public. In this situation, execute the following command:<\/p>\n\n\n\n<div class=\"wp-block-cgb-code-block code-block\"><div class=\"code-block-snippet is-type-body-default\">\n<p>chmod 400 jumpcloud_amazon_limux.pem&nbsp;<\/p>\n<\/div><\/div>\n\n\n\n<p>Next, we will use the SSH key to connect to our instance:<\/p>\n\n\n\n<div class=\"wp-block-cgb-code-block code-block\"><div class=\"code-block-snippet is-type-body-default\">\n<p>ssh -i &#8220;jumpcloud_amazon_linux.pem&#8221; ec2-user@ec2-18-153-64-122.eu-central-1.compute.amazonaws.com<\/p>\n<\/div><\/div>\n\n\n\n<p>The -i option in SSH lets you define the path to the private key file for authenticating your connection to a remote server. This is especially useful when managing multiple key pairs or when your key files are stored with non-standard names or in different locations.<\/p>\n\n\n\n<p>Upon your initial login to the Amazon Linux instance, you&#8217;ll be prompted to verify the host\u2019s authenticity. In this case, simply type &#8220;yes&#8221; and hit Enter to proceed.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"512\" height=\"64\"

since we provisioned a new Amazon Linux instance, but it is always advisable to search for the latest updates.<\/p>\n\n\n\n<p>Next, we need a Nginx web server for our static website and also for the purposes of reverse proxy for our Node.js application.<\/p>\n\n\n\n<div class=\"wp-block-cgb-code-block code-block\"><div class=\"code-block-snippet is-type-body-default\">\n<p>sudo dnf install nginx
