Downtime, it keeps every IT professional up at night. When talking about Disaster Recovery, a common question that I am asked is “What would happen if our data centre caught fire, was flooded or plagued with bugs?"
Our customers are, of course, reassured that the workloads we host for them on Oracle Cloud Infrastructure (OCI) are protected and replicated to another Oracle datacentre, in a different datacentre region, but what surprises me is that this next question rarely gets asked - “OK that’s good to know, but if a the datacentre were to catch fire, be flooded or plagued with bugs, how would you prioritise whose workloads (machines) and what workloads are recovered first?”.
It’s a great question and almost as important as that first question. Let us imagine that the recovery of an individual workload takes 10 minutes (wow! That’s pretty quick). Now imagine that requires support from Joe in Cloud Infrastructure, Sarah in Tech Application support, Eric, a DBA, as well as Charlie, the Service Delivery Manager who is keeping the customers updated. Keeping this in mind, now imagine we need to recover 10 workloads for every customer and that we have 10 customers affected – therefore;
Time Required = 10 workloads X 10 minutes each = 100 minutes per customer X 10 affected Customers = 1000 minutes or 16.6 hours. You can see the problem. Recovery is only as fast as the slowest resource and unfortunately, that’s human!
Recognising this, Oracle created Full Stack Disaster Recovery (FSDR). FSDR allows us to script all of the disaster recovery steps for all of the disaster recovery scenarios and then automate this with the press of a button.
Demonstrating this we recently completed a Disaster Recovery test with a well-known European University, whereby they failed over their production systems from Frankfurt to Amsterdam. They then ran normal business operations for one week in Amsterdam, before falling back to Frankfurt and unlike the picture I painted above, we used Oracle’s Full Stack Disaster Recovery process to automate the activity, meaning that we could (if ever put to the test) fail over multiple customers concurrently, resulting in full recovery in under four hours.
