This is my first blog post and I hope you will ignore mistakes. Thank you in advance.
In this blog post I will describe the step by step creation of Oracle cloud always free account and creating a Linux Virtual Machine.
Oracle Cloud Free Tier will allows you to sign up for an Oracle Cloud account which provides a number of Always Free services and a free credit of 300$ which can be use on all eligible Oracle cloud Infrastructure services for up to 30 days. The Always Free services are available for an unlimited period of time. Kindly click here to know more in detail.

You are now login to your cloud account
3. Network Configuration
Create Virtual Cloud Network (VCN)
Open the navigation menu. Under Core Infrastructure, go to Networking and click Virtual Cloud Networks
Select the compartment you want to create the network. Then click on Create VCN
Enter a name for the VCN For CIDR Block, I choose IP 192.168.10.0/24, so that I can use the private IP range b/w 192.168.10.1 to 192.168.10.254.
Now the VCN status is available
Click on VCN Name (ocvcn) and you will be redirected to VCN Details page. Under Resource select Subnets and then click Create Subnet
Enter the information as per the below screenshot and click on Create Subnet. Note: Public subnet has selected to access the instance in public n/w.
The subnet is now created
Configure Internet Gateway
From VCN Details page under Resources, click on Internet Gateways
Give it a name and choose the compartment, then click on Create Internet Gateway
Your internet gateway is created. but you still need to add a route rule that allows traffic to flow to the gateway.
Adding Route table
From VNC Details page, Under Resources –> Route Tables, click on the route table associated with your public subnet.
Click on Add Route Rules
This is for the public subnet. select Target Type as Internet gateway Destination CIDR Block: 0.0.0.0/0 (This means all the internet) Once ready, click on Add Route Rules
Now you can see the Internet gateway route has been successfully added
Adding Security lists
Check your public IP using the URL and whitelist it to access the cloud VM which you will be creating in the next steps
From Subnet Details page, Under Resources, select Security Lists and click on the Default Security List as shown below
Click on Add Ingress Rules
Source Type: CIDR Source CIDR: <Your Public IP>/32 IP Protocol: TCP; Source Port Range: All; Destination Port Range: All Once ready, Click on Add Ingress Rules
