Cloud-Based Disaster Recovery
Disaster recovery sites that mimic production, reducing upfront configuration and the on-going cost.

Disaster recovery (DR) is about preparing for and recovering from a disaster. Any event that has a negative impact on your IT systems operations could be considered a disaster. Disasters come in the form of hardware or software failures, a network outage, a power outage, physical damage to a building or human error;

To minimize the impact of a disaster, organizations invest time and resources to document, train, and update plans and procedures to deal with a disaster. The amount of investment for disaster recovery can vary dramatically depending on the recovery time objective (RTO) and recovery point objective (RPO) of the system.

When a disaster occurs, it is essential to quickly implement a disaster recovery plan that either commissions compute resources or to failover to already running resources.

A traditional disaster recovery strategy would involve the duplication of all, or a portion, of the production environment to ensure the availability of an alternate site in the event of a disaster. This physical environment would typically be geographically located a significant distance from the production facility so as to isolate the the site from faults that may impact the production site.

Depending on the criticality of the system, the DR environment may be configured in a fault tolerant manner. This normally involves duplicating the entire production site.

When a partial DR environment is in place (known as a pilot light configuration), minimal infrastructure is in place and spare capacity is configured when needed.

The infrastructure needed to support a DR environment would include, but not be limited to the following:

  • Facilities to house the environment including power and cooling.
  • Security to ensure the physical protection of assets.
  • Suitable capacity to scale the environment.
  • Support for repairing, replacing, and refreshing the infrastructure.
  • Contractual agreements with an Internet Service Provider (ISP) to provide Internet connectivity that can sustain bandwidth utilization for the environment under a full load.
  • Network infrastructure such as firewalls, routers, switches, and load balancers.
  • Enough server capacity to run all mission-critical services, including storage, for the supporting data and servers to run applications and backend services such as user authentication, Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), monitoring, and alerting.

Cloud-based Disaster Recovery

For disaster recovery, cloud computing provides a significant opportunity to address the challenges faced by use of physical environments during a DR scenario. Significant cost savings and agility to change and optimize resources during a DR scenario as a huge benefit.

While a reduction in capital expenditures and on-going maintenance costs are key factors, the flexibility and robustness of cloud-based disaster recovery environments provides an opportunity for a more robust response when a disaster occurs, leading to reduced effort to meet recovery objectives.

Key benefits of cloud-based training environments are:

  • Cost

    Cost is main factor for moving disaster recovery environments to the cloud. Upfront capital expenditures for environments are reduced, or eliminated. The pay-for-use model mean you only pay for the time the environment is in use.

  • Compliance

    Supports “cloud-first” organization mandates by moving training environments to the cloud.

  • Flexibility

    Configuring an environment for testing during disaster recovery testing is quick and cost effective in the cloud, and you don’t need to interact with your production environment.

  • Scalability

    Environments can be scaled to ensure that your disaster recovery instance meets user demand.

Cloud-based disaster recovery gives you fine grain control and flexible configuration options to build a disaster recovery solution that meets your recovery time and recovery point objects. On-demand configuration provides flexibility in responding to a disaster and pay-per-use pricing provides huge cost saving for DR environments, that are only needed in the event of a disaster.
