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 are ready to scale up at a moment’s notice to “hot standby” environments that enable rapid failover. With data centers in over dozen regions around the world, AWS provides a set of cloud-based disaster recovery services that enable rapid recovery of your IT infrastructure and data.
Tricolor will provide comprehensive solution using paradigm which best suits the situation and requirement.
Backup and Restore – Companies can use their current backup software to replicate data into AWS. Companies use Amazon S3 for short-term archiving and Amazon Glacier for long-term archiving. In the event of a disaster, data can be made available on AWS infrastructure or restored from the cloud back onto an on-premise server.
Pilot Light – While backup and restore are focused on data, pilot light includes applications. Companies only provision core infrastructure needed for critical applications. When disaster strikes, Amazon Machine Images (AMIs) and other automation services are used to quickly provision the remaining environment for production.
Warm Standby – Taking the Pilot Light model one step further, warm standby creates an active/passive cluster. The minimum amount of capacity is provisioned in AWS. When needed, the environment rapidly scales up to meet full production demands. Companies receive (near) 100% uptime and (near) no downtime.
Hot Standby – Hot standby is an active/active cluster with both cloud and on-premise components to it. Using weighted DNS load-balancing, IT determines how much application traffic to process in-house and on AWS.
