A simple and easy-to-use solution but not recommended for public apps

I would rate the overall solution a six out of ten. We have around five to six developers and engineers for the solution’s deployment and maintenance. You can use the solution if your website is not too big or complicated. However, if it is big and complicated, then you need to use Apache or Red Hat. This tool can be used for internal purposes. But if you plan to host a public app, then I wouldn’t recommend the tool.
