Wordpress should be good enough. You can read up tutorials on how to set it up on a LAMP or LEMP stack. But if you only want to create a Wordpress blog, then better to use shared hosting like @meetdilip suggested. However, if you want to run some other servers on the same machine, such as a voice server, then a VPS is better.
what is LAMP and LEMP stack?
LAMP = Linux + Apache + MySQL + PHP
Amazon Lightsail
Nah, it's okay. You can use it to test and if things so sideways, you can always destroy the instance and create a new one. Won't affect billing since billing is usually done by hourly usage.
To avoid hackers I changed my SSH port to something else from the default 22. I also set up ufw to block any request to ports other than the ones I have allowed.
I think he means something like this What is cPanel? How to use cPanel for WordPress hosting
Seems like something that hosting providers provide. I don't think VPS providers provide this since the VPS are fully managed by the user. I myself use plain old SSH and terminal to manage my VPS.
$15 per month. Nah, I think I will use it the old fashioned way.cPanel makes life easy. But it is paid. It is still worth trying it.
Yup, Bash shell FTW. I am pretty proficient with Linux so I don't have much trouble doing some admin work.
You want a vps with extra 8gb ram for what? I mean usually such large amount of ram is only required for specific workloads on a virtual server.
Not just small names,unless you take a plan with redundant storage option(obviously costs extra),a hardware/hdd failure can still cost you your data even with a big name provider.
