GitHub is Great for Open Source projects,
But i don't like GitHub and many other third-party code storage systems when it comes to building a Private-Product which is a highly closed-end system.
I believe in "Your-Code-Your-Responsibility".
Don't Transfer Your Responsibility to others or there will be greater consequences.
If your organization is not involved in open-source development.GitHub is not for you, Private organization must follow own approach to build a product.
Do it hard way to achieve best results,Setting own git server is piece of cake and secure too(If you want your product secure).
ssh-keygen -t rsa -b 4096 -C "firstname.lastname@example.org"
Copy local id_rsa for windows (C:/USER/YOUR-USERNAME/.ssh/id_rsa.pub) For linux(/root/.ssh/id_ras.pub) INTO Remote server /root/.ssh/authorized_keys
mkdir git-server cd git-server git init --bare
git clone root@ip-address:/git-server
If you like to make git more secure keep development and production copy where development copy is accessible to everyone in your organization and production copy allow only via special-mechanism such as Custom platform build in browser where user sync development code into production after checks-and-balance.
For my scenario (Single engineer)
I do not use git at the local/server.Simply use own platform where development code pushes into production mode after stable development channel.
IF I can do it as a single engineer, It's a teeny-tiny challenge for the Minimal Team of any organization.
In Case you care about your product.
