Disaster recovery (DR) is about preparing for and recovering from a disaster. Any event that has a negative impact on a company’s business continuity or finances could be termed a disaster. This includes hardware or software failure, a network outage, a power outage, physical damage to a building like fire or flooding, human error, or some other significant event.
To minimize the impact of a disaster, companies invest time and resources to plan and prepare, to train employees, and to document and update processes. The amount of investment for DR planning for a particular system can vary dramatically depending on the cost of a potential outage. Companies that have traditional physical environments typically must duplicate their infrastructure to ensure the availability of spare capacity in the event of a disaster. The infrastructure needs to be procured, installed, and maintained so that it is ready to support the anticipated capacity requirements. During normal operations, the infrastructure typically is under-utilized or over-provisioned.
With Amazon Web Services (AWS), your company can scale up its infrastructure on an as-needed, pay-as-you-go basis. You get access to the same highly secure, reliable, and fast infrastructure that Amazon uses to run its own global network of websites. AWS also gives you the flexibility to quickly change and optimize resources during a DR event, which can result in significant cost savings.
