when we can use linux server and write codes in our ubuntu os then why companies use third party cloud services such as digital ocean?
Many time student’s laptop configuration is low, in that case using the third party server is the best option. It is like purchasing a computer and accessing it remotely. And in the end , you have to use cloud services to deploy your final product so that other people can access your site/app etc.
Do let me know in case you need further assistance.
