I am planning to move to a new host when my hosting cycle expires. I am currently hosted in Singapore data center and when i look few reliable hosts i see they provide data centers in US and UK. My audience are from Asia (India), can i use CDN + UK/US hosts and get the same latency & speed as the Singapore data center?
Yes and no. If your site is largely static, in other words, has pages which never change, then the CDN would probably serve you well, however if it's dynamic like a forum, then the stylesheets, scripts, etc. will be served from the CDN and the main page from the server.
I'm not sure how much time this would be exactly, but it is possible that much of the site's load time is in the static assets like those which would result in a net improvement.
You can check what is taking up the most time with your browser's inspect tool (right-click > inspect > network and maybe a refresh to get it pulling in data).
And it really depends on the CDN, a few CDNs don't actually have data-centers in India to my knowledge, so the static assets might end up getting served out of Singapore anyway.
