托管专用服务器，其中多个IP分配给了子域

Question

I'm currently looking for a hosted server solution which is able to provide with:

• Apache or Nginx engine with PHP and MySQL support;
• multiple IPs (50 and more);
• possibility to edit PTR record, in a way every IP will point to different sub-domains of a single main domain (eg, 1.2.3.4 - sub1.domain.com, 1.2.3.5 - sub2.domain.com,. 1.2.3.6 - sub3.domain.com);

So, perfectly, that should be a bunch of web servers running sub-domains on different IPs (IPs' subnet level doesn't matter).

Any recommendations? Thank you in advance.

Answer 1

AWS should be able to provide what you want. In AWS

1. You can bring up EC2 Instance with LAMP AMIs which will provide you with the software you are looking for.
2. Each EC2 instance can have multiple private IPs (each private IP can be mapped to an elastic IP which are public). The following link explains exactly what you want: http://aws.amazon.com/about-aws/whats-new/2012/07/06/multiple-ip-addresses-for-amazon-ec2-instances-in-amazon-vpc/
3. Finally using AWS Route 53 Service you can direct each subdomain to each of your public IPs using a-name records. Of course I would recommend creating Amazon Load balancers and then using CNAME records to direct traffic to these Load balancers. But its entirely upto you how you want to implement it.

And It need not be AWS.. I think any sophisticated IaaS provider like rackspace or PaaS provider like Pivotal CF, Google App Engine etc should be able solve your problem only using different services and concepts.
