In this article, we are going to install Ubuntu Focal Fossa LTS on Oracle Cloud. The steps are very easy and it takes less than five minutes to complete.
For the uninitiated, Ubuntu 20.04 LTS nicknamed “Focal Fossa” is a long term support release. This means that this distribution will be supported for up to 5 years by Canonical. Supported here means commitment to patch, updated and maintain the operating system.

Oracle Cloud virtual instances
Oracle Cloud offers a free tier whereby you are given the opportunity to launch two virtual machine to install Ubuntu Focal Fossa LTS on Oracle Cloud compute platform.
And the best thing about these virtual machines is that they are always free which is super great for beginners to lower down their startup cost.
Oracle virtual machines are called “Shape” and below are the specifications for this free compute services:
Items Specifications Number of free virtual machines 2 CPU 1/8 OCPU for each virtual machine (AMD based, 2 threads) RAM 1 GB for each virtual machine Block volumes storage 50 GB for each virtual machine Object storage 10 GB Archive storage 10 GB Allocated bandwidth 0.48 Gbps
So if you want to deploy a database driven website, you have the opportunity to deploy the website and database into separate virtual servers to enhance your data security.
Furthermore it is always a good idea to separate them because if your website gets hacked, at the very least if the setup was proper, the attacker should only have limited access to your database.
Please do note though that you’ll need a credit card to be able to register for Oracle Cloud Infrastructure (OCI) and to enjoy the always free tier benefits. Plus you’ll receive a credit amount of US$300 to test other services that are available in OCI for 30 days.
