Thanks William for a response,
yes, site is on wordpress and w3 cache is already installed. I have it on all wordpress sites.
godady, 1and1, bluehost etc.. had problems with all of them.
The thing is that site speed is very important for us. Site will have 30% of traffic through mobile phones. Also, the site will be in a very competitive niche with high cpc. As you know, site speed also influence your Quality Score.
I should have asked a little different. obviously there is no need for a server. what combination would be the best for this money range? Will there be an advantage in using CDN as a plus to Cloud hosting?
