AWS Elastic Disaster Recovery (DRS) minimizes downtime and data loss with fast, reliable recovery of on-premises and cloud-based applications. It continuously replicates physical, virtual, and cloud-based servers to the AWS Cloud to support business RPOs measured in seconds.
The DRS console lets you track the progress of failback replication to your source server. You can also boot the Failback Client to perform a failback to any other Recovery instance.
Cost-effectiveness
AWS Elastic Disaster Recovery is a cost-effective way to ensure business continuity. It replicates data and applications to a secondary region, enabling RPOs measured in seconds and RTOs measured in minutes after a disruption. It can also be used to improve application resilience and meet compliance requirements. AWS DRS can recover a variety of servers, including physical infrastructure on AWS, VMware vSphere, and Microsoft Hyper-V as well as standard cloud infrastructure running supported Windows or Linux operating system versions.
Unlike traditional on-premises solutions, AWS Elastic Disaster Recovery uses affordable storage and minimal compute to maintain an up-to-date copy of your data. It can also be used to test a fail-back strategy without disrupting ongoing production operations. In addition, it is accessible through AWS PrivateLink, which reduces security risks and optimizes bandwidth usage. This makes it an ideal solution for enterprises seeking to scale their DR infrastructure.
Scalability
Disaster recovery is a vital component of any cloud solution. It involves creating backups in multiple Regions and restoring infrastructure from the recovery Region after a disaster occurs. AWS Elastic Disaster Recovery is a highly scalable, cost-effective DR service for physical, virtual and cloud servers that provides high RPOs and low RTOs.
This enables organizations to minimize downtime by providing rapid recovery after disasters. The service also helps them avoid costly on-premises infrastructure that sits idle until needed. For example, if the web server receives ten simultaneous requests, the system automatically provisions nine additional machines from the cloud to serve them responsively.
Using a “Pilot Light Strategy,” AWS Elastic Disaster Recovery replicates applications to an alternate region, reducing costs by leveraging affordable storage and minimal compute resources. Then, it can deploy the replicated application to a recovery instance within minutes and restore data to an earlier point in time. It can also redirect traffic back to the original source servers using a mass failback client.
Flexibility
Unlike traditional disaster recovery solutions that require tapes to be stored on-premises, Elastic Disaster Recovery allows you to store your data in the cloud. This eliminates transportation and storing costs while providing quicker access to your data. Additionally, AWS’s DR solution uses continuous replication to ensure that your data is always up-to-date.
This solution helps you to recover your applications within minutes, based on the latest recovery point or a previous one. It also supports a non-disruptive failback. Moreover, you can easily launch test and drill instances for DR testing without disrupting production systems.
AWS elastic disaster recovery provides flexibility to meet your business needs, regardless of the number of servers you have in each region. This is due to the fact that you only pay for what you use. It is also possible to change the number of servers on your backup site without affecting existing applications. This means you can increase your capacity as your needs evolve.
Reliability
The reliability of AWS elastic disaster recovery is a critical factor in ensuring that business processes continue to operate. It enables businesses to achieve RPOs and RTOs that are measured in seconds and minutes, respectively. The service provides continuous data replication and supports both physical and virtual infrastructures, including VMware vSphere, Microsoft Hyper-V, and standard cloud infrastructure. It also enables users to recover all systems, databases, and applications that run on Windows or Linux. It even supports non-disruptive failback testing to verify that the DR system is working properly.
A key component of DRS is a continuous data replication process, which minimizes downtime windows by continuously copying the latest data from your source servers to an alternate site. It also provides a warm standby mode, which ensures that a scaled-down replica of your on-premises infrastructure is always available in an AWS region. This allows you to keep your production environment up and running without wasting resources.
