Hello friends we are going to start a online dating site so what may be the data transfer(monthly) for a site like this? As users will join the site and upload photos, videos,do chatting,internal messaging, sms, email. At first what plan can we choose and when users joining the site what plan to be choosen? What may be the data transfer(monthly) for a social networking site? Help me friends to choose a webhosting plan wisely?
Your questions here are really way too vague. Its near impossible to know how much transfer you will need. I would imagine, very little at first. You're best bet is to start small and scale up. Find a provider that can scale to meet your needs from Small Shared Hosting, on up to Dedicated Servers, if necessary. As your site grows, your provider should be able to grow with you!
At first, you need a small plan based on the Size of your website. Later, as and when your site grows, you can go for a higher plan. i would suggest something like this for a start: 1 Gb space 20 GB bandwidth let me know if you need help in chosing.
If the users are going to do the above activities then you will have to strictly consider a dedicated server. What applications you will be using for the chatting, internal messaging and sms.
If you're just starting out, don't worry too much about your space or bandwidth usage - as time goes by you'll have a better understanding of what you need. A small shared host would do for you for now.
At first what plan can we choose and when users joining the site what plan to be choosen? For starter,a low ended vps will be sufficient for the service you provide. What may be the data transfer(monthly) for a social networking site? Depend on the popularity of your site,normally 10GB most for first month.
