Despite your best efforts, everyday IT disruptions are going to occur at some point. Whether it’s a server failure, faulty software patch or malicious cyber-attack, your Plan A is going to fail. Your best defense against this eventuality is to safeguard your infrastructure with a ready to go Plan B that will enable it to Fail Forward Fast using a Software Defined Disaster Recovery solution.
A Software Defined Plan B
When it comes to IT disruptions and disaster recovery, having a Plan B refers to the secondary infrastructure that you might want to have ready when your primary infrastructure, or Plan A, goes down.
With Virtiant, you now have the option of a readily available, standalone, production-like environment that is fully software defined. The Virtiant solution connects directly to your vCenter while regularly pulling snapshots of your primary production environment. Since it is a standalone environment, Virtiant does not require any single component of your primary infrastructure, any component of which may have failed, to be working. This characteristic makes Virtiant unique as compared to similar solutions
Utilizing the Right Migration Approach
It’s certainly not unusual for IT administrators to manage their production environments through the use of Cold migration. In this scenario, you must shut down one of your systems before you can move to another. This process may work well when you are dealing with a scheduled migration where your user community is aware that systems will be unavailable. This then allows you to shut down all or portions of your system, making it unavailable to users until the work is completed.
There are obvious limitations to this method in the event of an unscheduled disruption. Cold migration, or cold fallback, cannot be done while your users are on the system. Downtime, and therefore lost revenue, becomes unavoidable. In contrast, hot migration can efficiently facilitate back to your production environment both planned downtime and unplanned disruptions. With this process, while your users are working on the system, the hot failback starts siphoning off data back to production. This allows for your users to remain actively working while migration is happening in the background until the last incremental data set is transferred and operations fully returned to the primary environment.
