My client created a ubuntu server 16.04 to deploy a web app. And I have been getting difficulties the get the app deployed properly ...
So is there a way for me to reset the server back to its original state via command line?
AWS doesn't have a feature like VmWare's restore snapshot. If you want the machine restore to its original state, you have to launch the machine again. But it will get a different IP. There is no way to reset your instance to its original state.
Update: Please check this answer as Amazon recently added this feature in 2021. Check this Amazon link
