AWS Lightsail: A Hands-On Introduction for Beginners

Launching Your First Lightsail Instance

Now that you're in the AWS Lightsail console, you’re ready to launch your first instance.

Step 1: Create an instance

To start, click Create Instance - as shown in the image below. This will take you to the instance creation page.

Step 2: Choose an instance image

The image below provides an example of the screen you will see when creating an instance. The exact appearance may vary based on your AWS Region, Availability Zone, and console version.

The first choice you have to make is to determine what operating system or pre-configured software stack your instance will use. 

Lightsail gives you two options:

• Apps + OS images: If you want to deploy an instance quickly, pick a pre-configured application stack such as WordPress, LAMP, or Node.js. This saves you time by setting up both the OS and the software in one go.
• OS-only images: If you prefer setting up everything from scratch, choose a bare operating system like Ubuntu, CentOS, or Windows. These are great if you need full control over the configuration.

Another decision you have to make is choosing a region for your instance. AWS Lightsail operates from multiple data centers worldwide, and the region you pick will affect the latency and performance of your instance. 

If your audience is primarily in North America, an instance in a US-based region will provide faster response times. If you serve users in Europe or Asia, select a region closer to them to minimize delays.

The image below highlights some of the available AWS Regions and Availability Zones. AWS periodically expands its infrastructure by adding new Regions and Availability Zones, so check for updates to find the best option for your needs.

Step 3: Choose an instance plan

Your next step will be to decide on a pricing plan based on your computing needs. 

At the time of writing, AWS Lightsail offers fixed-cost plans starting at $5 per month. These prices increase as you add CPU power, RAM, and storage.

The image below displays a selection of available plans, which may be updated periodically.

• The basic plan is enough for small websites, test environments, or simple applications.
• If you expect higher traffic or need more processing power, you might want to choose a mid-tier or high-tier plan.

One of Lightsail's benefits is its predictable pricing; there are no unforeseen fees, which makes it an excellent option for those who are new to cloud hosting.

Step 4: Configure instance details

To customize your instance, you should adjust a few settings before launching it:

• Give it a unique name: This makes it easier to identify if you plan to manage multiple instances.
• Set up SSH key pairs: This is a crucial security step. AWS will generate one for you if you don’t already have an SSH key. You will need this later to connect to your instance securely.
• Adjust networking settings: Here, you can configure firewall rules to control which types of traffic are allowed. For example, a web server might need to allow HTTP (port 80) and HTTPS (port 443) while other ports remain restricted for security reasons.

Step 5: Launch your instance

Once everything looks good, click the Create Instance button. It usually takes a few minutes for Lightsail to begin the background setup process.

The image below shows an instance being set up in the background.

The image below shows a ready instance.

You now have a cloud-based server ready to host your application, website, or development environment!

Managing Your Lightsail Instance

Once your instance is up and running, the next step is managing it effectively. This includes connecting to your instance, taking backup snapshots, and configuring networking for stable and secure access. Let’s go through each of these tasks.

Step 1: Connecting via SSH

You can connect to your instance using SSH directly from the Lightsail console using the built-in terminal. 

The images below show where you can connect using SSH and the built-in terminal you will be presented with.

If you prefer using an SSH client like PuTTY, you need the private key from the SSH key pair you set up earlier.

Lastly, check the instance status in the console to make sure your instance is operating as it should. 

Step 2: Managing snapshots

Snapshots are essentially backups of your instance and come in handy for disaster recovery or migration. 

To create one, go to the Snapshots tab in your instance’s management page and click Create Snapshot.

The image below shows the Snapshots tab in the Lightsail console.

If anything ever goes wrong with your server, you can restore a snapshot to bring it back to a previous state.

Step 3: Managing networking

To ensure stable and reliable access to your instance, you’ll need to configure its networking settings. This includes assigning a Static IP, setting up DNS configurations, and managing firewall rules.

• Assign a Static IP. Without one, your instance's public IP might change if it restarts, which can be a problem if you are running a website or an application that relies on a fixed address.
• Configure DNS settings. Link your domain name to your Lightsail instance. This is useful if you are hosting a website and want visitors to access it using a custom domain rather than an IP address.
• Set up firewall rules. Control who can access your instance by allowing only the necessary traffic—for example, enable SSH (port 22) only for your IP and limit other open ports to trusted sources.

Deploying Applications on Lightsail

With your Lightsail instance set up and networking configured, you’re ready to deploy applications.

Step 1: Installing software

The next step is installing the software you need. To do this, you will need to connect to your instance via SSH. 

Remember, if you are using the Lightsail console, you can click the Connect button to open a browser-based terminal. Alternatively, you can use an SSH client like PuTTY or your command line if your SSH key is set up.

You might need software like Apache, MySQL, and PHP for a basic web server setup. You can install them with a single command:

sudo apt update && sudo apt install apache2 -y

The command above updates your package list and installs Apache, which serves web pages to visitors. 

Depending on your application, you may also need to install other components, such as PHP for dynamic content or MySQL for database management.

Step 2: Setting up WordPress

If you are deploying a WordPress website, AWS Lightsail makes it even easier. Instead of installing everything manually, you can select the pre-configured WordPress blueprint when creating your instance. This automatically sets up WordPress, MySQL, and all the necessary components.

Once the instance is running, open a web browser and navigate to your Lightsail instance’s public IP address.

You should see the WordPress setup screen, where you’ll configure your site name, admin account, and other settings.

To improve performance, consider enabling caching and setting up a Content Delivery Network (CDN). Lightsail has built-in CDN support, which helps speed up your site by serving content from edge locations closer to your visitors.

Step 3: Deploying a custom web application

If you are working with a custom web application instead of WordPress, you will need to upload your code manually. 

The easiest ways to transfer files to your instance are:

• SCP (Secure Copy Protocol) – If you just need to upload a few files, you can use SCP to securely transfer them from your local machine.
• Git – If your code is stored in a Git repository, you can clone it directly onto your Lightsail instance using:

git clone https:// github. com/name-of-your-repo

After uploading your files, you will need to install dependencies. 

For example, if you are running a Node.js application, you might install dependencies with:

npm install

Next, configure your web server. If you are using Nginx, you must set up a configuration file to serve your application properly.

Finally, store sensitive information securely using environment variables instead of hardcoding them in your application. You can do this by exporting variables in your shell or using a .env file that your application reads.

Once everything is set up, restart your web server and check that your application is running correctly. 

At this point, your custom app is live on AWS Lightsail!

Scaling and Optimizing Lightsail

As your application grows, you may need to improve performance, handle more traffic, or increase storage capacity. AWS Lightsail provides several ways to scale and optimize your setup, whether by upgrading your instance, distributing the load, or expanding storage.

Step 1: Scaling your instance

You have two primary choices if your Lightsail instance is having trouble keeping up:

1. Upgrade to a bigger plan (scale vertically) – This means creating a new, more powerful instance and moving your data over. AWS does not offer an automatic upgrade, so you will need to handle migration manually.
2. Scale horizontally – Instead of just one bigger instance, you can also choose to spread the load across multiple smaller ones. You can pair this with a Lightsail load balancer to keep things running smoothly.

Step 2: Adding more storage

If you are running out of space, you can do the following:

1. Navigate to the Storage section and attach a new block storage volume.

2. Use the following command to mount it to your instance:

sudo mount /dev/xvdf /mnt/new_storage

3. If you want this to persist after a reboot, update /etc/fstab.

Step 3: Load balancing

If traffic spikes, you can use a load balancer. A load balancer distributes incoming requests across multiple instances, keeping performance steady. 

Lightsail’s built-in load balancer makes this easy.

You can also automate instance deployment with snapshots and scripts for better scaling.

Monitoring and Security in Lightsail

Keeping your Lightsail instance running smoothly and securely requires proactive monitoring and proper security measures. By tracking performance metrics and following security best practices, you can prevent issues before they impact your application.

Monitoring performance

The Metrics tab allows you to monitor your instance’s health. You can check CPU usage, network traffic, and storage. 

If something looks wrong, set up alerts to catch issues before they become serious problems.

Securing your instance

You can secure your Lightsail instance with these simple steps:

• Disable root login – Use key-based SSH authentication instead for better security.
• Tighten firewall rules – Only open the ports you actually need.
• Enable automatic updates – This helps patch vulnerabilities without extra effort.

Conclusion

I’ve found AWS Lightsail to be a great option for developers and small businesses who need a simple, scalable, and cost-effective cloud hosting solution. It takes the complexity out of AWS while still giving you the flexibility to deploy and manage applications with ease.
