DRaaS Cloud to Cloud : why it still is a necessity?

Is a DRaaS needed when your infrastructure is migrated to Cloud ?

You have migrated your infrastructure to a public or private Cloud, and you think you can stop thinking about an IT continuity plan because your Cloud provider is commited to SLA availability of 99.9%. And that's a common cyber-security mistake.

Moreover, some think, in the same spirit, that migrating to Cloud means not having to backup your data. This is wrong! As well as not checking for your Cloud provider backup policy or Recovery plan when switching your IT to SaaS solution is a really bad idea.

We will explains the risk of all mentioned earlier, but first, let's talk about the many differets Cloud situations:

Private Cloud

Set of dedicated hypervisors that do not incorporate intrinsic backup mechanisms

Public Cloud

Many areas of availability but does not include automatic failover mechanism

Which disaster scenarios are not covered?

Climate disaster

One of the most real cases was the shutdown of the 3 AWS' data centers in New Orleans during 2005 Hurricane Katrina. The effects were very important, Datacenters were stopped several days. This scenario is becoming more real even in France and Europe.

Breakdown of fluid or telecom

Recently few Clouds have had shutdowns (often related to electrical incidents or telecom interruptions) of several hours, which had impacts on some customers over 24 hours.

Human error

Despite precautions implemented in the Cloud (especially the Public Cloud) to put men at distances of infrastructure, unexpected error can happen. To minimize human intervention, administrators work only through controlled configuration deployment. ..

Equipment failure at the heart of the infrastructure

This scenario regularly happens and randomly affects Clients instances, stopping their IT for a few minutes to several hours.
