# Overview
{: #overview}

The Deploying Resilient AIX workloads on Power Virtual Server pattern deploys a multi-region solution on Power® Virtual Server that includes backup, high availability, and disaster recovery. This pattern can be used to provide an all-in approach for deploying a resilient power architecture within the Power® Virtual Server for AIX workloads.

The solution does not address application or database level high available design.
{: note}

- It can support up to 99.99% infrastructure availability when deployed as a multi-region.

- It can support local high availability to protect from immediate LPAR failure.

- It can support backups for AIX workloads to protect against data loss and can support disaster recovery scenarios.

- It can support out-of-region disaster recovery.

The Power® Virtual Server resiliency pattern is intended to:

- Accelerate and simplify solution design by providing a standard IBM Cloud deployment architecture reference following the IBM Architecture Design Framework.

- Provide a prescriptive, end-to-end enterprise-class solution design, with diagrams, component architecture decisions along with rationale for cloud component selection for a resilient architecture.

- Ensure that requirements can be met from a performance, system availability, and security perspective.

## Pattern Considerations
{: #considerations}

- Backup AIX data using a managed backup service.

- Provide OS level local high availability between two AIX LPARs.

- Provide a disaster recovery solution using SAN to SAN replication between two regions.

Always validate offerings are available in the regions you are deploying by using the [IBM Cloud portal](https://cloud.ibm.com/login).{: note}

Resiliency needs to be considered for both the infrastructure and application levels. This pattern doesn't address application or database level high availability design. Consider latency between environments before deciding on a replication method. Consider options for synchronous and asynchronous replication when designing database replication to meet the requirements.{: note}
