Hi Hoang,
Thank you for your reply. Can I toss a few questions your way?
I am not a DBA or server administrator so I fear leaving security holes. Do you manage the security of the VM yourself?
Azure uses a third party named ClearDB for MySQL and the pricing is ridiculous. What database do you use? Are you paying for ClearDB MySQL or just using the free, small instance?
Also, what size VM are you using? Shared, 1, 2, or 4 core?
Thanks!
