High availability over Internet

by Alex F., last login 2 days ago

High availability over Internet  This is a solution I recently deployed for a client.

There are two parts:
1) The flow of incoming/outgoing traffic: client initiates request and is directed to a server based on DNS interogation (reports show a 50-50% connection balance for two servers) and the HTTP server delivers the content;

2) Background service communication and data synchronization over the Internet. 
Automatic file system replication ensures that periodic data synchronization scripts are unneeded; databases are automatically replicated and can be also load balanced; sessions replication ensures that no matter where the client lands the second time he initiates a request, his activity is not interrupted.

Notes: The system can be grown to larger sets.
Advantages: No Single Point of Failure. If one node fails, you just exclude it\'s DNS entry. If one hosting provider fails, you have another one available. high availability over Internet
