Are you trying to guard against rogue sys admins, or do you suspect that the security is so bad that the other users/apps on that server might be able to get at your files? Either way, I advise to select a different provider (or a different hosting plan) that you have trust in.
Well, its not secret.
I was considering "sandbox" like feature offered by a hosting company for free.As we all know, free comes with its own cost
But luckily, another friend of mine(reliable,longtime friend) has offered me free hosting for the initial couple of months.That should be enough to test my App.
And thanks for the replies
I use Heroku for ruby apps and am very happy with it. This is great for testing apps, as well as apps that have launched but have relatively little traffic.
It's free until you need more dynos or workers.
One dyno and zero workers should be enough if it's just normal usage. A single dyno can usually serve about 15 requests per second.
However, if you have some requests that are doing heavy duty processing, for example, in one of my applications a single request can make several thousand calls to an external API, which means that during that time, the dyno is unable to serve any other requests.
