Platforms for Web Application Deployment

you’reWith the complexity of software development increasing and more innovative and data-intensive applications evolving or being created every year, there has been an explosion of services to allow teams to deploy their products on the internet and scale them with ease. This has created a new kind of service called cloud computing: the on-demand delivery of IT resources over the internet with pay-as-you-go model pricing.

In this course, we will deploy the backend on AWS, mostly on an Elastic Compute Cloud (EC2) instance, which is just a fancy name for a VPS. Well, actually, an AWS EC2 instance is a virtual server in Amazon’s EC2 for running web applications. Let’s start by creating the AWS server.

Note: The following steps can work for any VPS, not just for an AWS VPS. If you can’t create a VPS on AWS, you can see other solutions such as Linode, Google Cloud Platform (GCP), Azure, or IBM. They provide free credit you can use for learning about their services.

Creating an EC2 instance

Follow these steps to create an EC2 instance:

Step 1

Make sure you are logged in to your AWS account. On the dashboard, open the EC2 console:

Step 2

On the EC2 console, launch a new instance:

You will be shown a page where you will have to configure the instance.

Step 3

Enter the name of the instance:

Step 4

The next step is to choose an operating system. We will use “Ubuntu Server 22.04 LTS” for the “Amazon Machine Image (AMI)”:

We are using Ubuntu here because of its security, versatility, and the policy of regular updates. However, feel free to use any other Linux distros you are familiar with.

Step 5

And finally, you will need to set the instance type and create a pair of keys for Secure Shell (SSH) login. After that, you can launch the instance:

Step 6

Wait a moment, and the instance will be created:

Step 7

Click the “View all instances” button, and you will see the created Postagram instance.

Step 8

Click the checkbox next to the name of the instance and click the “Connect” button:

This will redirect you to a page with the information and steps needed to connect via SSH:

Step 9

In the terminal, type the following command to connect via SSH:

Note: Before running the code, you would need to add your AWS access key and secret access key. Also, paste the key that you created in step 5 in ...
