I am new to this whole thing and am learning new things every day. What I want to do is Host the same site on diffrent servers. why ? If one of my server is down then the site will still work from the other server. This might be a noobish question but any help appreciated , did some google search but couldnt find any thing usefull. If any one can point me in the right direction that would be great.
Yes, visit mediatemple.net. They offer a "neighboring" feature where they will back-up and host the same content/data on your web site's server on many others and in case there is ever issues where the server is not running, the data will be available automatically thanks to their system which will replace your servers media under another for the sake of uptime. They have one of the best rates I've ever seen as far as VPS and Dedicated servers go. PM me if you need further help.
after a bit of snooping around I found this is not good for SEO. So I dropped the idea. @ Yousif Thanks for you input
Actually SEO wouldn't be effected if it was just for backup server. The best way to do this is to setup the backup server to rsync all databases and files every hour from the main server to the backup server. With rsync you only get data transferred that is new, not all files every hour. That way you have the same data and databases on the backup server. Then you setup your domain name with 4 nameserver entries. Godaddy allows you to do this. Not sure about other registrars though. So when the main server goes down... the nameservers are polled starting from position 1. Position 1 and 2 will be your main server and if they are down then position 3 and 4 will be polled and as they will be up and ready to accept traffic, your site will never be down. I helped set these kind of servers up when I was a systems admin for Hostgator. As for SEO, both servers have the exact same content, titles and keywords and if ip and nameservers are an issue in SEO, since the server wont be running full-time as the main domain, this is not really an issue.
Yeah its costly. He did say he wanted his site hosted on multiple servers though. He didn't say what it was for... it might be a necessary cost. And how would it affect SEO? The server would never be scanned unless the main server went down. How often would this happen and for how long? I doubt it would affect SEO since all the keywords, descriptions and content would be the same. Even the URL and domain would be the same.
This sounds like a round robin to me. Basically what round robin is used for is load balancing. In this case you have geographically distributed web servers. Let's suppose you have one domain name and three identical web sites residing on three servers with three different IP addresses. User1 is trying to accesses the site and then gets sent to the first IP address. User2 is trying to accesses the site and then gets sent to next first IP address. The third one gets sent to the third IP address.
Yes, that would be counted as load balancing. You can start load balancing with 1 main server, 1 extra server, 1 db server. Both main and extra server will connect to db server.
yes, I would make sure that your host is able to keep you online when your server is down. I would not recommend hosting the same site on 2 diff. servers as it will get penalized for duplicate content and may be banned.
Wow lot of feedback and now I an confused . Time for more research in to this . thanks for all the feedback guys
The backup server is just for that.. backup. In case of a Digg effect or something. It is not meant to be up for a long time. So just have the copy of the site have noindex for the engines. If they crawl the domain name, then it isn't a big deal since the backup server only comes online with the domain name when the first server is down. If your server is going down for a long time, you have bigger issues. But yeah a load balancing server might work out the same. I prefer a backup server so my customers never get downed page... even if its just a static page saying you are doing work on the site and it will be up soon.
just do round robin load balancing. Setup the dns zone file with the A addresses of those diffferent IPs
Sorry for bumping on this thread. I noticed other people using ns1.dnsmadeeasy.com ns2.dnsmadeeasy.com ns3... and so on .. until ns4. Will it help?
ns1.domain.com etc.. is only for DNS not for site hosting. All you have to do is get 4 ip address for 4 site and do a round robin so that traffic is directed to 4 sites in cyclic order. Just google round robin load balancing or see this
i do not think that you will need to do that if you host your site with good hosting service. now lot of them provide 99.9% up time guarantee
I dont think this will affect you seo at all.. This kind of server is a fail-over server on which will switch automatically incase one of it server fail. You can see there is a few hosting company offering 100% uptime and they are using this ^^. You also can do this by using RSync ^^.
