Hey guys! Ever wanted to dive into the world of cloud computing without breaking the bank? Well, you're in luck! Oracle Cloud offers a pretty sweet free tier that includes a Virtual Private Server (VPS). This means you can get your hands on some serious computing power without spending a dime. In this guide, we'll walk you through how to snag your own Oracle Cloud free tier VPS. Let's get started!

What is Oracle Cloud Free Tier?

Before we jump into the how-to, let's understand exactly what the Oracle Cloud Free Tier is all about. Oracle Cloud Free Tier provides access to a selection of Oracle Cloud services completely free of charge. It's designed to let developers, students, and anyone interested in cloud computing to explore and experiment with Oracle's platform. The free tier offers two types of free resources: Always Free and Free Trial. The "Always Free" resources are available for an unlimited time, as long as you use them at least once a month, while the "Free Trial" provides a limited-time access to a broader range of services with higher usage limits, typically for 30 days, coupled with some cloud credits. The Always Free tier is what makes it an attractive options, it allows you to keep your services running for as long as you want at no cost.

The Always Free tier includes:

  • Compute: Two AMD-based Compute virtual machines with 1/8 OCPU and 1 GB memory each.
  • Storage: 100 GB of Block Volume Storage, 10 GB of Object Storage, and 10 GB of Archive Storage.
  • Database: Oracle Autonomous Database (Autonomous Transaction Processing or Autonomous Data Warehouse).
  • Other Services: Load Balancing, Monitoring, Notifications, and more.

For many users, the free tier compute instance (the VPS) is the main draw. It allows you to host small applications, experiment with different operating systems, or even run a personal VPN. Understanding the available resources in the free tier is crucial before you start, so you know what you can realistically achieve without incurring charges.

Step-by-Step: Getting Your Free Oracle Cloud VPS

Alright, let's get down to business and get that free VPS up and running! Follow these steps:

1. Sign Up for an Oracle Cloud Account

First things first, you need to create an Oracle Cloud account. Head over to the Oracle Cloud website and click on the "Start for free" button. You'll be prompted to enter your email address, choose your country, and create an account name. Make sure to use a valid email address because you'll need to verify it later. The registration process also requires you to provide a credit card. Don't worry, you won't be charged unless you explicitly upgrade to a paid account. Oracle uses the credit card for verification purposes to prevent abuse of the free tier. Fill in all the necessary information, including your address and phone number.

  • Important Note: Double-check all the information you enter, especially your region selection. Some regions might have limited availability for free tier resources.

2. Verify Your Email Address

Once you've completed the registration form, Oracle will send you an email to verify your email address. Click on the verification link in the email to activate your account. This step is essential to proceed with the account setup.

3. Sign In to Oracle Cloud Infrastructure (OCI)

After verifying your email, sign in to the Oracle Cloud Infrastructure (OCI) console using the account name and password you created during registration. You'll be greeted with the OCI dashboard, which provides an overview of your cloud resources and services.

4. Create a Compute Instance (VPS)

Now comes the exciting part – creating your free VPS! Here's how:

  1. Navigate to Compute: In the OCI console, click on the navigation menu (the three horizontal lines in the top-left corner) and select "Compute" then "Instances".
  2. Create Instance: Click on the "Create Instance" button to launch the instance creation wizard.
  3. Name Your Instance: Give your instance a meaningful name. This will help you identify it later.
  4. Choose an Availability Domain: Select an availability domain within your region. Availability domains are isolated data centers within a region. Choose one that is available and suits your needs.
  5. Image and Shape: This is crucial. Click on "Change Image" and select a supported operating system. Oracle Linux, Ubuntu, and CentOS are popular choices. Then, click on "Change Shape". Make sure you select a shape that is eligible for the Always Free tier. Look for the shapes that include "VM.Standard.E2.1.Micro" or "VM.Standard.A1.Flex" (Ampere-based).
  6. Networking: Choose an existing virtual cloud network (VCN) or create a new one. A VCN is a private network within Oracle Cloud. If you're unsure, create a new VCN with internet access.
  7. Add SSH Key: This is how you'll access your VPS. Choose the option to "Add SSH key". You can either generate a new key pair, upload your public key, or paste your public key. If you're new to SSH keys, generate a new key pair and download the private key. Keep the private key safe, as you'll need it to connect to your VPS.
  8. Create: Review your configuration and click the "Create" button to launch your instance. Oracle Cloud will start provisioning your VPS. This process may take a few minutes.

5. Access Your VPS

Once your instance is up and running, you can access it using SSH. Here's how:

  1. Get the Public IP Address: In the OCI console, navigate to your instance details page. You'll find the public IP address assigned to your instance.

  2. Connect via SSH: Open a terminal or SSH client (like PuTTY on Windows) and use the following command to connect to your VPS:

    ssh -i <path_to_private_key> <username>@<public_ip_address>

    Replace <path_to_private_key> with the path to your SSH private key, <username> with the username for your chosen operating system (e.g., opc for Oracle Linux, ubuntu for Ubuntu), and <public_ip_address> with the public IP address of your instance.

    • Example: ssh -i ~/.ssh/my_oracle_key opc@192.0.2.1

  3. Accept the Security Warning: The first time you connect to your VPS, you'll likely see a security warning. Type yes to accept the warning and continue connecting.

  4. Log In: If your SSH key is configured correctly, you'll be logged in to your VPS. Congratulations! You now have a free Oracle Cloud VPS.

Optimizing Your Free VPS

Now that you have your free VPS, here are a few tips to optimize it and make the most of your resources:

  • Keep it Updated: Regularly update your operating system and software packages to ensure security and stability.
  • Monitor Resource Usage: Keep an eye on your CPU, memory, and storage usage to avoid exceeding the free tier limits.
  • Secure Your VPS: Implement security measures such as firewalls, intrusion detection systems, and regular security audits to protect your VPS from unauthorized access.
  • Use it Wisely: Remember that the free tier resources are limited. Use them wisely and only run essential applications and services.

Troubleshooting Common Issues

Sometimes, things don't go as planned. Here are a few common issues and how to troubleshoot them:

  • Instance Fails to Launch: This could be due to a lack of available resources in your chosen region or availability domain. Try selecting a different availability domain or region.
  • Unable to Connect via SSH: Double-check your SSH key configuration and ensure that the correct key is being used. Also, verify that the public IP address is correct and that your firewall is not blocking SSH traffic.
  • Out of Memory Errors: The free tier VPS has limited memory. Try optimizing your applications to reduce memory usage or consider upgrading to a paid instance with more memory.
  • Billing Issues: If you're unexpectedly charged, review your usage and ensure that you're only using Always Free resources. Contact Oracle Cloud support if you have any billing inquiries.
