The RaaS (Recovery as a Service) architectural model described, where the production application is placed in the cloud and the recovery or backup target is kept in the private data center, is known as "From-cloud RaaS." This model is designed for organizations that want to utilize cloud resources for their primary operations while maintaining their disaster recovery systems on-premises.
Here's how the From-cloud RaaS model works:
* Cloud Production Environment: The primary production application runs in the cloud, taking advantage of the cloud's scalability and flexibility.
* On-Premises Recovery: The disaster recovery site is located in the organization's private data center, not in the cloud.
* Data Replication: Data is replicated from the cloud to the on-premises data center to ensure that the backup is up-to-date.
* Disaster Recovery: In the event of a disaster affecting the cloud environment, the organization can recover its applications and data from the on-premises backup.
* Control and Compliance: This model allows organizations to maintain greater control over their recovery processes and meet specific compliance requirements that may not be fully addressed in the cloud.
