This document discusses using cloud infrastructure for disaster recovery planning (DRP). It notes that DRP is critical to prevent business downtime, loss of productivity, and other issues from outages and disasters. Implementing DRP can be expensive and complex, often requiring offsite data copies and remote resources. The document presents three common DRP strategies - cold, warm, and hot standby sites - and their characteristics. It argues that a cloud-based DRP can provide the availability of a hot standby at a lower overall cost due to pay-as-you-go pricing, easy data replication, and no hardware maintenance fees. The rest of the document provides examples of how to design and implement a cloud-based DRP

2. WHY IS
DRP
CRITICAL ? Today’s organizations are exposed to a wide range of outages
and disasters: fires, floods, viruses, hardware failures,
corrupted data and even human error.
A reliable RD strategy will prevent:
• Expensive business downtime
• Loss of productivity
• Breach in Customer Service Agreement
• Impact on reputation and/or financial assets

CHALLENGES
Usually a DRP will require:
• access to data copies
• ressources located in remote sites.

AND CLOUD  Also helps to simplify the DRP maintenance process and
provide real time flexibility.
DRIVE DRP
In a nutshell, main benefits are:
SUCCESS
• No, or very limited, CAPEX in cloud based DRP.
• No long term commitment for site or equipment rental.
• With cloud-based DRP, you don’t have to build a DR platform,
you just rent one which will perfectly fit your requirements.
• Platform is flexible. It will grow with your business for a
predictable cost.
• Cloud and virtualization will support multi-tier design in order to
mix private and ‘virtual private’ clouds if needed.
• Overall Cost Of Ownership and Operation significantly lowered
by:
• Pay as you go and only for what you use model
• Easy data replication and no fee data import
