The EHR Healthcare Systems case study notes that there are several legacy file and API-based integrations with insurance providers that will be replaced over the next several years. The existing systems will not be migrated to the cloud. This is an example of a rip-and-replace migration strategy.

Even though the existing systems will not be migrated, new cloud-native systems will be developed. As an architect working on that project, you would consider several challenges, including the following:

 Understanding the volume and types of data exchanged

 Deciding how to authenticate service requests

 Encrypting data at rest and in transit

 Managing encryption keys

 Decoupling services to accommodate spikes in service demand

 Designing ingestion and data pipelines

 Monitoring and logging for service performance as well as security

 Using multiregion storage and compute resources for high availability while operating within any regulations that put constraints on where data may be stored and processed

In addition to these technical design issues, the architect and business sponsors will need to determine how to retire existing on-premises systems while bringing the new systems online without disrupting services.
