Most of the website that are running today are shared hosting because of the affordable price but the problem is when you have to much heavy traffic your website will be suspended because of disturbances of other user accounts in shared hosting. The best solution if you have limited budget is to run your website with cdn known as content delivery.
Two powerful free CDN providers are the incapsula and cloudflare. Cloudflare is more popular than incapsula because it started first compare to incapsula.
CDN gets you ahead like a corporate company website because you can leverage powerful traffic to your website at no cost only you have to change the DNS of your dashboard panel in domain management settings.
If you have problem with the speed of your website then the solution is to get 3rd party CDN so your website will booster in speed ,scalability , accelerate in performances , advance security and better ranking in google.
