Disaster Recovery (DR) cloud solutions

Disaster Recovery (DR) cloud solutions often include switchover and failover capabilities. Here's an overview of some products and services that facilitate these operations:

### Oracle Cloud Infrastructure (OCI)

OCI Full Stack Disaster Recovery: As discussed, this service provides orchestrated failover and switchover between OCI regions and supports comprehensive automation for databases, applications, and other cloud services.

### Amazon Web Services (AWS)

- AWS Elastic Disaster Recovery: Formerly known as AWS CloudEndure Disaster Recovery, it enables quick recovery into AWS from any physical, virtual, or cloud-based infrastructure. It supports both failover and planned migrations (switchover).

- Route 53: While not a DR product per se, AWS's DNS service can route traffic during failover or switchover scenarios with health checks and failover routing policies.

### Microsoft Azure

Azure Site Recovery (ASR) provides both failover and failback capabilities for applications running on Azure or on-premises. It supports orchestrated recovery plans for complex multi-tier applications.

- Azure Traffic Manager: This can be used for DNS-based traffic routing during failover or planned switchovers and offers endpoint health checks.

### Google Cloud Platform (GCP)

- Google Cloud's Disaster Recovery Planning Guide: While Google doesn't offer a single product named for DR like others, it provides methodologies and tools like:

  - Google Cloud Interconnect and VPN for connectivity.

  - GCP's Global Load Balancing for traffic management during failover.

  - Migrate for Compute Engine to move workloads and provide recovery.

### Third-Party Solutions:

Zerto Offers an IT Resilience Platform for cloud-agnostic disaster recovery. It provides continuous data protection and can perform failover and switchover with minimal data loss.

- Veeam: Known for its backup solutions, Veeam also orchestrates disaster recovery with Veeam Availability Orchestra, allowing for planned failover and failback operations.

- Veritas NetBackup: Besides backup, it includes disaster recovery features with automation capabilities for failover and failback processes.

- Druva: Provides cloud-native backup and disaster recovery services with automated failover and failback capabilities.

- Rubrik: Offers cloud data management with disaster recovery options, including orchestration for failover and switchover.

### Specialized Tools:

- Carbonite: Offers solutions for data protection that can include disaster recovery with capabilities for failover.

- Commvault: Provides comprehensive data management solutions, including disaster recovery with orchestration for switchover and failover scenarios.

### Features to Look for in Cloud DR Products:

- Automation: Automated failover and failback processes to reduce human error and recovery time.

- Orchestration: Ability to define and execute recovery plans for complex application stacks.

- RTO and RPO: The Goal is to minimize downtime and data loss by setting a low recovery time objective (RTO) and recovery point objective (RPO).

- Testing: Non-disruptive DR testing capabilities.

- Cross-Cloud: Support multi-cloud or hybrid cloud environments if required.

- Compliance: Ensure the solution meets regulatory data handling and disaster recovery requirements.

When selecting a product, consider its technical capabilities, compatibility with existing systems, ease of management, cost, and the level of support the vendor provides. Each solution has nuances, so matching it with your specific use case, scale, and operational requirements is crucial.
