The program complex Atlant
Atlant is designed to solve the task of guaranteed availability of sites in case of problems with the server. For this using an additional (hereinafter - secondary) server or VPS with sufficient resources to operate the site. On the secondary server rises copy of the domain, configure synchronization of files and databases from the primary server, one of the NS of site is transfering to the secondary server IP.
On both servers runs the script for monitoring, which changes the DNS settings to switch traffic to a secondary server if the primary is unavailable. In the case of switching data synchronization primary -> secondary stops. At the same time, if it's necessary, can be started secondary-primary to maintain the relevance of the data . Switching back occurs manually after the problem will be eliminated on the primary server that caused the switching.
Because switching is performed by resources of DNS, it does not happen instantaneously - 3 minutes before the determination of inaccessibility of the primary server, and 1-2 minutes for switching traffic to the secondary server.
Perfect solution to guarantee the availability of CJ and other resources.
In order to take part in testing Atlant you need choose VPS (we recommend a series of bigmem) or a dedicated server, which will serve as secondary. VPS at the time of testing is free. You will also need domain name that will participate in the testing and access to the main server. Domains can be multiple. All the information you need to specify in the ticket with the theme "Atlant - test".
