With the deepening of enterprise digital transformation, more and more companies are choosing to deploy business-critical applications to the cloud, and Amazon Web Services (AWS), as the world's leading cloud computing platform, provides a wealth of Disaster Recovery (DR) capabilities to help enterprises cope with a variety of possible disaster scenarios. Developing an appropriate AWS disaster recovery strategy not only ensures business continuity, but also reduces the risk of data loss and improves an organization's ability to respond to unexpected events.
Why disaster recovery (DR)?
Disaster recovery is an important part of every organization's information technology strategy. No organization can predict all possible disaster events - from natural disasters to cyber-attacks, even human error can have a significant impact on business. The purpose of disaster recovery is to ensure that in the event of a business disruption, the business is able to resume operations in the shortest possible time, minimize data loss, and minimize the impact on customers and the brand.
Risks faced by businesses include:
Business interruption: Technical failures, network outages or data loss can bring business to a halt, impacting revenue and customer satisfaction.
Data loss: Improper backups or storage failures can lead to the loss of critical data, posing compliance and legal risks.
Damage to brand reputation: Prolonged downtime or service interruptions can lead to a decline in customer trust, affecting an organization's market position.
By implementing a disaster recovery strategy, organizations can ensure rapid recovery and business continuity after a disaster, while protecting customer data and sensitive information.
RTO and RPO
Before designing a disaster recovery strategy in AWS, organizations must first understand the Recovery Time Objective (RTO) and Recovery Point Objective (RPO).
Recovery Time Objective (RTO): refers to the maximum amount of time it takes from the onset of a disaster to the restoration of services. RTO is a key indicator of an organization's tolerance for business interruption.
Recovery Point Objective (RPO): refers to the maximum acceptable data loss time. That is, the maximum tolerance for data loss in the event of a disaster.
With RTO and RPO clearly defined, organizations can choose the appropriate AWS services and architectures based on these objectives to achieve different levels of disaster recovery requirements.
Choosing the right AWS DR strategy types
AWS offers a variety of disaster recovery strategies, and organizations can choose the most appropriate option based on their needs, budget, and business criticality. Here are a few common disaster recovery strategies:
Backup and Restore
This is the most basic disaster recovery strategy. Businesses regularly back up their data to a storage service such as Amazon S3 or S3 Glacier. In the event of a disaster, organizations can restore data from the backups.
⚡Pros: Low cost and simple to implement.
⚡Cons: Longer recovery time, usually for business scenarios that don't require fast recovery.
Pilot Light (Minimum operating environment)
Under this strategy, organizations deploy their most critical business environments to AWS, but keep them minimal. In the event of a disaster, the organization can quickly scale that environment and restore a full production environment.
⚡Pros: Scales faster in the event of a disaster and is suitable for most organizations.
⚡Cons: The need to reserve a certain amount of computing and storage resources for the base environment increases some of the costs.
Warm Standby
The Warm Standby strategy requires organizations to keep core services on AWS and running continuously, albeit under a lighter load. When disaster strikes, organizations can quickly scale resources to restore business functions.
⚡Pros: Faster recovery times than Pilot Light for most businesses that require shorter recovery times.
⚡Cons: Slightly higher cost than Pilot Light because of the need to maintain a portion of compute resources and storage services.
Multi-Activity (Active-Active)
For applications that require high availability and zero recovery time, the Multi-Active strategy is to run the production environment in multiple AWS regions simultaneously. Each region is capable of handling business requests, ensuring business continuity. In the event of a failure, traffic is automatically switched to another available region with virtually no recovery time.
⚡Pros: Provides near-zero recovery time, suitable for business-critical systems.
⚡Cons: Higher cost, requires deployment of resources in multiple regions and efficient load balancing.
