Abstract

Cloud computing depends on multi-region disaster recovery (DR) as a vital practice to maintain business operations during substantial outages. Organizations using Amazon Web Services (AWS) worldwide infrastructure implement disaster recovery through duplicated critical systems that span different geographical areas to minimize data loss and downtime. AWS users can establish multi-region DR strategies which this paper examines through specific implementations targeting e-commerce operations and healthcare as well as financial institutions. This paper explicates multi-region DR strategies including Recovery Time Objective and Recovery Point Objective followed by AWS implementation approaches with Amazon Route 53 along with AWS Lambda and Amazon DynamoDB global tables and AWS CodePipeline and AWS CloudFormation among other services that support effective multi-region DR. The paper demonstrates how a failover capable Route 53 DNS system pairs with DynamoDB global data replication for an active/passive deployment example. The text explores both the difficulties which include expenses and complexity alongside poor data coherence and inadequate testing methods and offers effective guidelines for multi-regional DR including routine disaster recovery exercises and similar configuration deployment between areas in addition to automated processes to minimize mishaps. The evidence confirms that AWS multi-region DR configurations following AWS Well-Architected Framework standards deliver dependable resilience and continuation to crucial business operations in any business sector.
