Using AWS Disaster Recovery to Close Your DR Datacenter
Maintaining physical Disaster Recovery (DR) datacenters grows more cost-prohibitive each year. By moving your DR data center to the AWS cloud, you enable faster disaster recovery and greater resiliency without the cost of a second physical datacenter. In this webinar, we covered: -Architecting “pilot light” to “hot standby” DR environments -Multi AWS Availability Zone DR strategies -What cloud DR offers that on-premises options can’t -Lessons Learned from DR implementations on AWS -Demo: Building a hot standby DR environment Learn more at https://www.softnas.com/aws

- 5. Terminology Business Continuity Business Continuityensures an organization's critical business functions continue to operate or recover quickly despite serious incidents. Disaster Recovery Disaster Recovery (DR) enables the recovery or continuation of vital technology infrastructure and systems following a natural or human-induced disaster. Recovery Point Objective Recovery Time Objective RTO is a targeted duration of which a business process must be restored after a disaster or disruption. RPO is the maximum targeted period in which data might be lost from an IT service due to a major incident.

DR Datacenter vs.AWS On-Premises •High cost to build disaster recovery sites or datacenters (CapEx) • High cost of storage, backup, archival and retrieval tools, and processes (OpEx) • Difficult planning, procurement and deployment • Challenging to verify DR plans • Single level of DR across the organization AWS • Low cost upfront investment (CapEx) • On-demand costs (OpEx) • Consistent experience across AWS environments • Recovery automation • Separate levels of DR per application or business unit

- 16. Backup & Restore– How itWorks Advantages • Simple to get started • Cost effective (mostly backup storage) Preparation Phase • Start SoftNAS Cloud 30 day free trial • Install and configure SoftNAS Cloud • Describe procedure to restore from backup on AWS • Know which AMI to use, build your own as needed • Know how to switch to new system • Know how to configure the deployment In Case of Disaster • Retrieve backups from S3 • Bring up required infrastructure • EC2 instances with prepared AMIs, Load Balancing, etc. • Restore system from backup • Switch over to the new system • Adjust DNS records to point to AWS Objectives • RTO: as long as it takes to bring up infrastructure and restore system from backups • RPO: time since last backup

Customer DR Example Customerhas a combination ofTier 1,Tier 2, andTier 3 business applications.They did the following: Tier 1 Apps RPO & RTO <15 minutes Multi-site DR • Critical core elements of system already configured • EC2 instances running for critical services • Pre-configuredAMIs forTier-2 apps that can be quickly provisioned upon failure • Cloud infrastructure load-balanced and configured for automatic failover • Initial data synchronization using in- house backup software or FTP • Incremental data replicated / synchronized using cloud NAS Tier 2 Apps RPO & RTO <4 hours Pilot Light DR • EC2 instances for all services running at all times • In-house and cloud infrastructure load-balanced and configured for auto-failover • Initial data synchronization using in-house backup software or FTP • Incremental data replicated / synchronized using cloud NAS • All data replicated into S3 bucket • Initial data synchronization using in house backup software or FTP • Pre-configured AMIs forTier 1 and Tier 2 apps quickly provisioned upon failure • Incremental data replicated / synchronized using cloud NAS • EC2 instances spun-up from objects within S3 buckets Tier 3 Apps RPO & RTO <8 hours Backup & Restore

Editor's Notes
- #9 Fast Performance: Fast disk-based storage and retrieval of files. Compliance: Fast retrieval of files allows you to avoid fines for missing compliance deadlines. Elasticity: Add any amount of data, quickly. Easily expire and delete without handling media. Secure: Secure and durable cloud disaster recovery platform with industry-recognized certifications and audits. Partners: AWS solution provider and system integration partners to help with your deployment. Businesses are using the AWS cloud to enable faster disaster recovery of their critical IT systems without incurring the infrastructure expense of a second physical site. The AWS cloud supports many popular disaster recovery (DR) architectures from “pilot light” environments that may be suitable for small customer workload data center failures to “hot standby” environments that enable rapid failover at scale.
