What is Oracle’s forever Free VPS (Ampere ARM A1)?

If you’re looking for a free Virtual Private Server (VPS), you might be wondering what Oracle’s forever Free VPS (Ampere ARM A1) is all about. 

In short, it’s a great way to get started with Oracle’s cloud infrastructure services without having to pay anything upfront. Ampere ARM A1 is a low-cost, cloud-based server that’s perfect for websites that are starting out.

Oracle’s free VPS comes with 24GB of memory, 4 CPU cores, and 20GB of storage, and you can use it for as long as you like.

There are some caveats though. First, the service only has limited availability, so you might have to keep checking to secure one for you when new capacity is added at Oracle Cloud’s end. 

Second, the forever Free VPS doesn’t have port 25 open. So, if you need to send Emails, you’ll have to upgrade to a paid plan or use an external SMTP service. 

Overall, Oracle’s forever Free VPS is a great way to get started with the company’s cloud services. It’s one of the best freebies available and it won’t cost you anything upfront. Just keep in mind that you’ll need to upgrade if you need more resources than what’s included in the free plan.

Prerequisites for Openlitespeed installation on Oracle’s Free VPS (Ampere ARM A1)

To install Openlitespeed on Oracle’s free VPS (Ampere ARM A1), there are a few things you’ll need to do first.

1. Make sure you already have a VPS with Oracle cloud, which is of type Ampere ARM A1.

2. Make sure you have a supported Linux distribution installed. We are going to use Ubuntu in this Tutorial. So, it’s best if you install or re-install your VPS with Ubuntu version 22.04. Though, any Debian 11 should work fine.

3. Make sure you have root access to your server. This is necessary to install the required packages and configure the server properly.

3. Ensure that your server meets the minimum system requirements for Openlitespeed. We recommend at least 2 CPUs and 6GB of RAM on ARM A1, as processing power on these instance types is comparatively low.
