Hi and Welcome to the Hands-on Disaster Recovery on AWS CloudIn this course, we are going to deploy a multi-tier application in various configurations, test disaster recovery options, and compare recovery time (RTO) and data loss (RPO)I am Chandra Lingam, and I am your instructor. Here is what you will learn in this courseWe start by discussing key concepts and terminologies.“Everything Fails, All the Time” - Werner VoglesYou will learn about Resiliency and Availability (and, more importantly, what do they mean)What differentiates fault tolerance and high availabilityAnd why high availability alone is not disaster-proofOnce we understand the basics, we then jump into the labsYou will deploy a multi-tier web application [using DynamoDB Global Table, Lambda, API Gateway, EC2, Elastic Load Balancer, and Route 53]And then explore backup and restore optionWe will use AWS Backup and configure point-in-time-recovery (PITR), schedule backups, and maintain copies in a second regionWe then simulate malicious data loss and corruption and how to recover the dataAnd how to handle the loss of a region using Backup and RestoreFor the next lab, you will reconfigure the App in Pilot Light modeAnd then observe how it helps minimize the data lossWe will then upgrade the infrastructure as Warm StandbyAnd how it helps reduce the recovery timeFinally, we look at the multi-site active-active configuration for a zero-downtime solutionYou will also learn how DR changes with relational databases such as RDS and AuroraWe will configure point-in-time-recovery, schedule backup and continuous replicationWith Aurora Global Database, you will perform both Managed Failover and Unplanned Failover to a DR RegionThis is an intermediate level course and you need to have an AWS account with administrative accessYou also need to be familiar with EC2, ELB, IAM, and DatabasesI am looking forward to meeting you!
