Hi and Welcome to the Hands-on Disaster Recovery on AWS Cloud

In 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 course

We start by discussing key concepts and terminologies.

"Everything Fails, All the Time" - Werner Vogles

You will learn about Resiliency and Availability (and, more importantly, what do they mean)

What differentiates fault tolerance and high availability

And why high availability alone is not disaster-proof

Once we understand the basics, we then jump into the labs

You 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 option

We will use AWS Backup and configure point-in-time-recovery (PITR), schedule backups, and maintain copies in a second region

We then simulate malicious data loss and corruption and how to recover the data

And how to handle the loss of a region using Backup and Restore

For the next lab, you will reconfigure the App in Pilot Light mode

And then observe how it helps minimize the data loss

We will then upgrade the infrastructure as Warm Standby

And how it helps reduce the recovery time

Finally, we look at the multi-site active-active configuration for a zero-downtime solution

You will also learn how DR changes with relational databases such as RDS and Aurora

We will configure point-in-time-recovery, schedule backup and continuous replication

With Aurora Global Database, you will perform both Managed Failover and Unplanned Failover to a DR Region

This is an intermediate level course and you need to have an AWS account with administrative access

You also need to be familiar with EC2, ELB, IAM, and Databases

I am looking forward to meeting you!

Happy Learning!
