Substitute for digital ocean

can i use my system or a local system instead of digital ocean

Hello there deepa90prasad,
DigitalOcean is a cloud based paid platform which is used to host ur projects.I would suggest you to use digital ocean instead of a local system.
and if you are looking for a platform other than digital ocean, there are plenty available like -InMotion Hosting,BlueHost,etc

yes you can use your desktop based ubuntu OS.

Thanks…how can I use a local Host for this?
What are the steps I have to follow
