Disaster Recovery

Backup and Restore

Backup and Restore is a cost-effective disaster recovery strategy that can help your organization to mitigate the risk of data loss, corruption, and regional disasters. This approach involves backing up data while restoration remains inactive, making it easy to quickly recover critical data when needed. With cross-region backup, AWS can copy stored data in one region and replicate it in another, providing an extra layer of protection. While this option may be better suited for lower priority use cases, it can still provide peace of mind to businesses that require reliable disaster recovery solutions. Trust in AWS to help you protect your data and keep your business running smoothly, even in the face of the unexpected.

The core benefits of this include:

  • Suitable for lower priority use cases that do not require instant backup and recovery
  • Provision all AWS resources after event of a disaster or outage
  • Restore their backups after an event
  • The most cost effective

Pilot light

In Pilot Light architecture, the production environment operates similarly to a backup and recovery solution. With this approach, your production environment is continuously replicated from one Availability Zone to another, ensuring that your data is always available. In the event of a disaster, the replicated data is routed to the disaster recovery region, where a minimal version of your application environment is already up and running. This makes it easy to scale up and quickly restore full functionality, minimizing downtime and ensuring business continuity. AWS Pilot Light architecture is a cost-effective solution that can help you prepare for the unexpected and keep your business running, no matter what.

The core benefits are:

  • Data live
  • Services idle
  • Provision some AWS resources and scale after event
  • Costlier than Backup and Restore as it replicates data periodically

Warm Standby

This architecture involves maintaining a partially active secondary environment that is ready to take over in case of a disaster. With Warm Standby, you can ensure that your systems are continuously replicated, and that application code is periodically synchronized to minimize data loss and downtime. In the event of a disaster, the secondary environment can be quickly scaled up to provide full functionality to end-users, ensuring that your business stays competitive and meets your customers’ needs. While Warm Standby is a more costly option than Pilot Light, it provides faster recovery times and greater resilience, making it an excellent choice for businesses that require high availability and rapid recovery in case of a disaster.

The core benefits are:

  • Always running but smaller
  • Business critical
  • Scale AWS resources after event
  • Optimal but costlier than the other two options

Multi-site Active/Active

If you are looking for the ultimate in disaster recovery solutions, look no further than AWS Multisite Active/Active. With this architecture, you will enjoy high availability and resiliency, deploying multiple active environments across various locations or Availability Zones. And here is the best part: all environments are fully active, providing full functionality to end-users simultaneously. Plus, with continuous data replication and load balancing, you will enjoy zero downtime and near-zero data loss.

This architecture is perfect for mission-critical services that require the highest level of redundancy and resiliency. And while it may be more complex and costly than other disaster recovery options, the peace of mind that comes with knowing your business will continue to run smoothly, even in the face of an unexpected outage or disaster, is priceless.

The core benefits are:

  • Zero down time
  • Near zero data loss
  • Mission critical Services
  • Comes at an inflated cost as it is the most robust
