What is Disaster Recovery? How Does it Works?

Enterprises often worry about disruptions to their production systems when faced with natural or man-made disasters. A key driver for many businesses to undergo digital transformation is the need for effective “Disaster Recovery and Backup” solutions. How can resilience in production systems be maintained to minimize the impact? Nextlink Technology aims to guide enterprises in enhancing their backup and disaster recovery capabilities through conceptualization and deployment of solutions.

What is Disaster Recovery?

Disaster Recovery is like when, for instance, earthquakes or typhoons damage the electrical equipment of a building, leaving it without power. If the building has backup generators in place at that moment, it can swiftly maintain the operation of essential infrastructure, preventing power outages from causing further impact.

In the daily operations of a business, the risks go beyond just power outages in data centers. Natural disasters, internal incidents, and even large-scale cyber attacks all have the potential to disrupt operations. Disaster Recovery involves establishing additional backup sites or facilities outside of the operational location to ensure business continuity, with the primary goal of reducing the risks mentioned above.

How Does it Works?

Traditionally, businesses had to purchase or lease physical data centers for Disaster Recovery, leading to high costs. Therefore, adopting Cloud Disaster Recovery provides businesses with the advantages of high flexibility and fault tolerance while optimizing cost management.

The concept of cloud-based remote backup involves running applications in the cloud, spreading systems and backup data across servers and storage spaces in multiple regions. Failover is configured to automatically switch in case of a disaster. This ensures that when a disaster strikes, businesses don’t have to worry about applications failing to run, achieving the goal of reliability.

Taking AWS as an example, one service is AWS Elastic Disaster Recovery, allowing for the quick recovery of cloud-deployed applications, reducing downtime and the risk of data loss. Additionally, services like Amazon Aurora relational database offer cross-regional deployment solutions, facilitating swift recovery of backups.

Disaster recovery is crucial for public cloud environments to prevent operational disruptions.

AWS Emphasizing Application Recoverability with Disaster Recovery!

In the real world, business applications often encounter unforeseen events. Besides deploying pre-established solutions for remote backup, what methods are available to make applications resilient and recoverable?

AWS introduces the Fault Injection Service (FIS), a fully managed service for fault injection, allowing teams to scan application vulnerabilities in a stress testing environment to enhance performance and resilience. In the simulated environment of stress testing, teams can assess the performance of Amazon EC2 virtual machines, CPU and memory efficiency within Amazon EKS fully managed Kubernetes services, and connection latency. Moreover, applications deployed across multiple availability zones and regions can undergo power outage stress testing through FIS.

By conducting stress tests in experiments, uncovering previously unseen application vulnerabilities, it ensures that applications can effectively handle emergencies under any pressure.

Do your applications and core systems have a mechanism for remote backup? Can they still run smoothly under stress testing? The Nextlink Technology team assists you in application testing, providing best practices for disaster recovery. With 24/7 uninterrupted cloud hosting technical support, you can confidently entrust your applications to be managed by Nextlink Technology, allowing you to focus on business development!
