==Redundancy between two data centers ==
= 1 Server Basic System =
 
There's always a risk that data center in which you keep your servers can be down for various reasons.
 
To reduce such risk you can consider implementing redundancy between two data centers that are located in different countries or continents.
 
However, such implementation can work only if both data centers can meet requirements which are described [[Recommended_hardware#Requirements_for_multi-server_deployment | here]] (see '''Redundant servers''').
 
The most common problem is that different data centers cannot ensure such requirements for Virtual IP.

Here you can review the possible MOR implementations.

You can start with a single-server solution and scale the system as your business grows.

On all listed implementations it's recommended to deploy Asterisk and DB servers in the same datacenter to ensure stable system functioning.

Even though it's possible to deploy these elements in different locations, such implementations may cause many issues, related to delays between different networks.



1 Server Basic System

Up to 500cc

This is a very basic solution All-in-one-Server. No redundancy, no High-Availability, no Scalability.

We recommend to use it only in the testing environment.

Not safe to use in the real business environment.

2 Servers Solution with 2 IP Addresses

Up to 1000cc

The solution allows placing two servers in different locations.

In case of broken connection or broken database replication between servers, each site will become separated systems and runs its own billing, which is not desirable in most cases.

It provides double capacity with increased risk of malfunctioning in case of hardware/software/network failure.

2 IP Addresses allows route balancing at the side of the customers/vendors. They will use 2 IPs to balance traffic on their side.

2 Server Redundant High-Availability Solution

Up to 500cc

This is the most popular solution because it is fully redundant and most stable.

More info: 2 Server Redundant Solution

3 Server Non-High Availability Solution

Up to 1000cc

Not-recommended solution because of the risk to have main components on one server.

4 Server High Availability Redundant Solution

Up to 1000cc

The recommended solution for High-Availability, Redundant System.

Complete Redundancy, high-performance system with SIP balancer

Up to 2000cc, 100 CPS

  • GUI is on DB servers
  • Proxy servers share 1 IP managed by Heartbeat
  • DB (Core-Asterisk/GUI) servers share another 1 IP also managed by Heartbeat
  • LinuxHA heartbeat monitors Database servers
  • If one of the Core-Asterisk servers fails, SIP balancer routes calls via remained Core-Asterisk servers.
  • More Core-Asterisk Nodes can be connected, example with 2 is a bare minimum
  • When Main Database fails - Backup Database sees that and after 10s (default) will take Virtual IP, it is done automatically.
  • When Main Database is back up - Backup Database returns Virtual IP to Main Database and system starts to function in normal work flow (done automatically).
  • GUI server is connected to Backup Database to avoid load on Main Database in normal work flow.
