How to retrieve the rarely changing master data quickly

Question

Hi Guys,

I have some master records in my web application. It changing rarely but i am using frequently across the  application. Whenever i try to retrieve it from database it taking some long time. Because my application and database are in different physical location.

So to improve the application speed, I would like to manage the data in the application itself. But the concern is i want to return updated data for very next request itself whenever the these data get changed.

Can anyone suggest the best way to achieve this. I am using Angular 2, Asp.net web API and MySql.
