A competitive BCP / DRP
07/03/2014
As soon as a significant number of users (70 to 80 in this case) depend on a critical service (an ERP for example) for their daily professional activity, the issue of the business continuity or recovery plan (BCP / DRP) becomes essential to the system administrator's sleep quality and the company manager's serenity.
Of course, the service is hosted on a server installed in a fully equipped white room ensuring a very high level of reliability (SLA of 99.95%! ). And the data is replicated locally on duplicated disks.
What if the server fails anyway? What if the network access to the server is interrupted? What if an accident, fire, or attack destroys the white room?
What if, in addition, the administrator is unavailable and unreachable at that moment, say on vacation at sea on a sailboat... ?
Then, one of the authorized company managers would just need to click a button, confirm, and the service would immediately be available again on the backup server installed 400 km from the main server.
All this is now a very accessible reality (except for the administrator's vacation at sea on a sailboat).
