An aws disaster recovery services (DR) strategy helps ensure your business stays up and running in the face of a data center or network failure. These services include backups, replication, and failover to mitigate against data loss. They also provide monitoring and alerting to help you detect potential issues.
DR Planning and Implementation
An in-depth assessment of your current infrastructure, critical applications and resources to formulate a reliable AWS DR plan aligned with your business continuity objectives. Guidance on evaluating recovery time objectives and recovery point objectives, determining backup methods and frequency, establishing a remote location for data storage, leveraging AWS tools and services to create a DR runbook and automated testing to help ensure the integrity of your DR strategy.
A scalable approach that replicates your business-critical data, systems and applications to multiple AWS locations. In the event of a disaster, this enables you to recover your data and applications with minimal downtime and with a low RPO. This strategy is typically implemented using multi-region or multi-Availability Zone (AZ) architecture, and uses Amazon EC2 Auto Scaling to automatically move workloads between multiple instances in different AZs.
This DR strategy allows you to have a scaled-down version of your production environment in the cloud that is always running. This is useful for mission-critical systems that can’t afford any downtime. This approach combines several different AWS services, including Amazon EC2 and Amazon S3, to achieve the lowest RTOs and RPOs of any AWS DR strategy.
In this strategy, a clone of your production environment is deployed in another AWS Region and used to serve traffic in the event of a disaster. This is a popular DR approach, and can be combined with the multi-site active/passive or active/active/passive AWS DR approaches.
A cloud-to-cloud solution that connects on-premises data centers and the AWS cloud to provide seamless data and application integration. This enables you to leverage AWS services and features for AWS DR, including load balancing, DNS failover, application performance and security.
Managing your AWS DR strategy requires continuous monitoring and testing to identify potential issues. Fortunately, there are a variety of AWS tools and services that you can use to automate the process, minimizing manual effort and improving your response times. In addition, you can use AWS CloudFormation to define and provision infrastructure resources as code, reducing deployment complexity and simplifying management. You can also rely on AWS CloudWatch to monitor your system’s health and performance, providing notifications when metrics reach critical thresholds. Lastly, you can use AWS Reserved Instances to guarantee capacity in the event of a regional failure, mitigating the impact of natural or technical disasters on your critical business applications.
