It details the interaction between on-premises or cloud-based data sources and the AWS Cloud environment, highlighting the role of the AWS Replication Agent in performing continuous, block-level, compressed, and encrypted data transfer. The architecture explains the automated creation of staging area resources, including lightweight EC2-based replication servers and EBS volumes within the user's VPC. Furthermore, it outlines the recovery process, where recovery instances are launched in designated recovery subnets, achieving low Recovery Time Objectives (RTO) in minutes and Recovery Point Objectives (RPO) in seconds. This architecture ensures high availability and resilience for mission-critical workloads through efficient, automated disaster recovery procedures within the AWS ecosystem.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/technology/","Technology",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/aws-elastic-disaster-recovery-general-architecture/656189/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/aws-elastic-disaster-recovery-general-architecture/656189.png","ImageObject",300,407,{"name":42,"@type":43},"4398046744996","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-31","2026-10-25",true,{"@type":52,"interactionType":53,"userInteractionCount":30},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"What
