AWS Disaster Recovery Whitepaper
AWS Disaster Recovery Whitepaper, one of the most important Whitepapers for both the Associate and Professional AWS Certification exams
Disaster Recovery Overview
AWS Disaster Recovery whitepaper outlines AWS services that can be used for disaster recovery (DR), processes to minimize the impact on data, systems, and overall business operations.
It outlines best practices for improving your DR processes, including minimal investments to full-scale availability, fault tolerance, and explains how AWS services can help reduce costs and ensure business continuity during a DR incident
Disaster recovery (DR), is the process of preparing for and recovering after a disaster. A disaster is any event that has a negative effect on a company’s financial or business continuity could be considered a disaster. AWS recommends that you always plan for failuresDisaster Recovery Key AWS services
RegionAWS services can be accessed in many regions around the world. The DR site location, in addition to the primary location, can also be selected.
StorageAmazon S3provides a durable (99.999999999%!) storage infrastructure that is designed for primary and mission-critical data storage.
Stores Objects redundantly on multiple devices across multiple facilities in a region
Amazon Glacier is a low-cost storage solution for data backup and archiving.
Objects are optimized to be used infrequently, so retrieval times of several hours (3-5) are sufficient.
Amazon EBS allows you to create snapshots of data volumes at a point in time.
Snapshots can be used to create volumes, and can be attached to running instances.
Amazon Storage Gateway is a service that allows seamless and secure integration between your on-premises IT environment, and AWS’s storage infrastructure.
AWS Import/Exportaccelerates moving large amounts of data into and out of AWS by using portable storage devices for transport bypassing the Internet
Amazon’s high-speed internal network transfers data directly to and from storage devices.
ComputeAmazon EC2provides resizable compute capacities in the cloud that can be easily created or scaled.
Preconfigured AMIs are used to create EC2 instances
Multiple AZs can launch EC2 instances, which are designed to be protected from failures in other AZs.
NetworkingAmazon Route 53is an extremely reliable and scalable DNS web service
It includes a variety of global load-balancing capabilities, which can be very useful when dealing with DR situations such as. DNS endpoint health checks and the ability of failover between multiple ends
Elastic IPaddresses allow you to mask instance or Availability Zone failures through programmatically remapping
Addresses are static IP addresses that are used for cloud computing.
Elastic Load Balancing, (ELB), performs health checks and distributes incoming traffic across multiple EC2 instances.
Amazon Virtual Private Cloud (Amazon VPC), allows you to provision a private, isolated area of AWS cloud where resources may be launched in a defined virtual network
Amazon Direct Connect makes it easy to establish a dedicated network connection between your on-premises environment and AWS.
DatabasesRDS, DynamoDb and Redshift are fully managed RDBMS, NoSQL, and data warehouse solutions that can scale easily
DynamoDB provides cross-region replication
RDS offers Multi-AZ and Read Replicates, as well as the ability to snap data from one region to another.
Deployment OrchestrationCloudFormationgives developers and systems administrators an easy way to create a collection of related AWS resources and provision them in an orderly and predictable fashion
Elastic Beanstalkis a simple-to-use tool for scaling and deploying web applications and services.
OpsWorksis an application administration service that makes it simple to deploy and manage applications of all sizes.
