An IP you can transfer between servers
If you have a dedicated server with us, you may use the IP fail-over feature for managing your projects, SSL certificates,etc.
The IP Failover may be moved from one server to another in a few seconds. An account with an IP Failover works without intervals and is the best solution in case of hardware malfunction, overloaded applications or other infrastructure problems.
If you'd like to use all the advantages of having an IP Failover, your account configuration must be based on the IP Failover instead of the fixed IP address.
Moreover, if you move IP Failover between two servers, you will keep the configuration.
You need to make copies of your projects and configuration files between the servers. The configuration files for moving the IP Failover between two servers remain unchanged and all the services will work on the other server. You don't need to assign your projects to the new server's fixed IP.
Here are different examples of its use :
1) Change / Upgrade of the server
Your projects are on the dedicated server A (fixed IP A) and are configured to Failover Z.
You may order a new server if server A isn't sufficient to manage your projects. It's described as server B with fixed IP.
You need to make copies of your projects and configuration files from server A to B. Then...
... you can change the routing of IP Failover Z from server A to server B. Information about your projects, configuration files are assigned to your IP Failover on server B. It doesn't require any change in configuration (DNS, APACHE, SMTP, POP3, MySQL ...).
2) Functioning as the main server and the backup server
you have two servers A and B, the server A is your main server, server B is your backup server.
Your projects are configured on IP Failover Z, routed to server A. You can perform regular copies of your projects between the servers.
You can change the routing of IP Failover from server A to B when server A is down. All your services will work on server B. You will have time to repair your A server.
When the A server is repaired, you copy your data from server B to A. Then you change the routing of IP Failover for B to A. As a result all services work on the A server again.
This configuration has two advantages:
- you make a copy of data stored on A
- you use B server when A is down
3) Hosting of several projects
If you administer a larger number of websites, you may use 2 IP Failover addresses. Some of your websites will be assigned to IP Failover Y and the rest to Z.
When server A doesn't have enough power to manage sites on both Y and Z IP Failover, you may order a new server B and route IP Failover Z to the B server. Server A won't be administering the sites for Y IP Failover which will result in lowering the load and improving its performance.
