# High availability overview
{: #shared-high-availability}

Ensuring high availability (HA) is important for all cloud-based applications, and it is all the more critical for regulated workloads that the IBM Cloud for Financial Services is intended to host. In short, consumers depend on your application and cannot afford downtime. Using the VPC reference architecture and following the controls of the IBM Cloud Framework for Financial Services help you achieve that goal. When building an HA solution in IBM Cloud, you need to consider your workloads that run in virtual servers or Red Hat OpenShift on IBM Cloud and the HA characteristics of all of the other IBM Cloud services your solution depends on.

## HA for the reference architectures

See the following resources depending on which reference architecture you are using:

- [High availability for VPC reference architecture](https://cloud.ibm.com/docs/framework-financial-services?topic=framework-financial-services-vpc-architecture-high-availability&format=markdown)
- [High availability for Satellite reference architecture](https://cloud.ibm.com/docs/framework-financial-services?topic=framework-financial-services-satellite-architecture-high-availability&format=markdown)

## HA in IBM Cloud services
{: #ibm-cloud-services}

Your HA strategy needs to consider all of the IBM Cloud services in your deployment. The following table provides references to additional information on HA for each service in the reference architecture.

The references cover the steps that the service has taken to achieve high availability as well as the steps you must take. For example, consider Direct Link. The Direct Link service itself makes use of multiple zones within a region to help achieve HA. However, you Direct Link is not a redundant service at the cross-connect router (XCR), so you have the responsibility for creating redundancy through your border gateway protocol (BGP) schemas. See [High availability and disaster recovery for Direct Link](https://cloud.ibm.com/docs/dl?topic=dl-ha-dr&format=markdown) and [Models for diversity and redundancy in Direct Link](https://cloud.ibm.com/docs/dl?topic=dl-models-for-diversity-and-redundancy-in-direct-link&format=markdown) for more details.
