Introduction

In today’s age of the internet, data is the new gold because many businesses rely on the data hosted in the cloud. As the dependency on Cloud-based services is increasing, the need for a robust Disaster Recovery(DR) plan has become of utmost importance.

AWS Disaster Recovery

Amazon Web Services (AWS) provides a pool of Disaster Recovery solutions that help businesses to ensure high availability and continuity of their critical resources. 

Continue reading this article will help you understand AWS Disaster Recovery, key AWS Disaster Recovery Services, its advantages, and working with some FAQs at the end.

What is AWS Disaster Recovery?

AWS Disaster Recovery is nothing but a plan on how to recover computer systems and data if a disaster happens. 

This plan includes steps for backing up your data, restoring your systems, and getting back to work as quickly as possible. AWS offers a variety of Disaster Recovery solutions that can help to protect the data and systems in times of disaster.

These solutions can help to keep businesses running even when things go wrong.

For example, if the data centre of some company gets destroyed by a hurricane, they can use AWS Disaster Recovery solutions in order to restore their data and systems from a backup in a data centre in another location. 

This can prevent any significant data loss and make the company get back to work as quickly as possible.

Advantages of AWS Disaster Recovery

There are many advantages of using AWS Disaster Recovery that include:

  • Minimized downtime: AWS DR solutions could help in minimizing the downtime during the time of a disaster. Disaster recovery allows us to store data and systems in multiple locations, so if any one location gets disturbed, we can still access the data and systems from another location

 

  •  Reduced data loss: AWS DR solutions help us to reduce data loss in times of a disaster because we can keep multiple copies of the data in different locations, so if one copy is lost, we can backup from other locations
     
  • Cost-effective: AWS DR services follows pay on-the-go pricing model, which means business need to pay only for the resources that have been used during the disaster recovery process
     
  • Automated Failover: AWS DR solutions automate the failover process, which reduces the recovery time objectives (RTO) and ensures that the applications resume their processes as quickly as possible after a disaster

 

  • Easy recovery: AWS DR solutions make it easy to recover the data and systems in the event of a disaster. AWS also provides a wide range of tools and services that helps in automating the recovery process

AWS Disaster Recovery Services

Now let us discuss some of the Key AWS Disaster Recovery Services:

Amazon S3 Replication 

Amazon Simple Storage Service (S3) is a highly durable and available object storage service. This service replicates the data across different regions in AWS so that it is still available even if one region becomes unavailable during the disaster. 

S3 Replication

This method offers asynchronous replication for improved redundancy, and it is beneficial for businesses that need protection of their data against regional disasters.

Amazon Elastic Block Store (EBS) Snapshots

EBS Snapshots allow businesses to create point-in-time copies of EBS volumes. EBS are the storage volumes that are attached to EC2 instances. These snapshots can be used to restore volumes or create new volumes in different Availability Zones. 

EBS Snapshots

EBS is a good option for businesses that must protect their data from hardware failures or accidental deletions.

Multi-AZ Deployment

AWS offers Multi-AZ (Availability Zone) deployment for certain services like Amazon RDS (Relational Database Service) and Amazon EC2 (Elastic Compute Cloud). 

Mutli-AZ Deployment

This deployment automatically replicates the data across multiple Availability Zones. This feature protects the business's data from Availability Zone outages.

AWS Backup

AWS Backup is a fully managed backup service, and it is used to back up the data from a variety of AWS services, ensuring data protection across various AWS services.

AWS Backup

It streamlines the process of setting up and managing backups for databases, file systems, and other AWS resources and provides a centralized way to manage the backups.

AWS Disaster Recovery Solutions (e.g., AWS Site-to-Site VPN)

For complex DR requirements, AWS provides dedicated disaster recovery solutions like Site-to-Site VPN, which provides features like secured and encrypted communication between on-premises data centres and the AWS cloud. 

Site-to-Site VPN

This helps in replicating and recovering critical workloads in the cloud during a disaster.

Working of AWS Disaster Recovery 

AWS DR services work on the principle of replicating the data and systems to various multiple locations. 

Replication of data can be done in a variety of ways, and it depends on the specific needs of the business or the individual. 

For example, we can replicate the data to different Availability Zones within the same AWS Region, or we can replicate the data to different Regions across the globe.

Now that the data and systems have been replicated, depending on the needs, we can use AWS DR services to recover them in the time of a disaster. This can be done either manually or we can automate the recovery process using AWS tools and services.

Frequently Asked Questions

What is meant by RTO?

RTO stands for Recovery Time Objective. It is the amount of time that the organization or the individual can afford without the data or the systems in the time of a disaster.

What is meant by RPO?

RPO stands for Recovery Point Objective. It is the amount of data that an organisation or an individual could afford to lose during the time a disaster.

What are the different types of disasters that affect business?

Many different types of disasters can affect a business, like Natural disasters such as hurricanes, floods, and earthquakes. Also, man-made disasters such as cyberattacks and data breaches.

How to choose right AWS DR services for business?

In order to choose the right AWS Disaster Recovery Services for business, some factors that can be considered are budget, data and systems, RTO and RPO.
