FHIR on AWS Serverless Architecture:Everything You Need to Know

Technology is booming across all industries, including the healthcare industry. However, complex data exchange between software systems can prove to be a challenge for healthcare providers. This is where the FHIR on AWS serverless architecture comes in.

Fast Healthcare Interoperability Resources

Fast Healthcare Interoperability Resources (FHIR) has been developed by the Health Level Seven International (HL7) to make data exchange simpler and more convenient for healthcare providers.

Here is all you need to know about the FHIR on AWS serverless architecture.

Resources and Interactions

The resources in FHIR serve as the basic building blocks. There are several types of FHIR resources, each of which has the same interactions. The interactions refer to the set of operations that are used to manage the resources. The FHIR is targeted for several interactions, including the following:

· Lab vendors

· Pharmaceutical vendors

· Immunization registries

· Clinical health laboratories

· Healthcare institutions

· Equipment vendors

· Regulatory agency

· Local health departments

· State health departments

· Healthcare vendors

AWS Serverless Architecture

With the serverless architecture feature of FHIR, healthcare institutions do not have to worry about the system’s infrastructure. The AWS serverless architecture allows several benefits, including quick implementation, lower costs, and more convenience. This form of FHIR architecture supports the following:

· The posting of Bundles

· Searching Observations and Patients

· Capability statement

· Reading and updating Patients

API Gateway

The Bundle type of FHIR resource maps to the Bundle API gateway resource. The Observation type of FHIR resource maps to the Observation API gateway resource. Similarly, the Patient type of FHIR resource maps to the Patient API gateway resource.

Amazon DynamoDB

Amazon DynamoDB is a managed service that organizations scale up their applications. It comes with a range of infrastructure features, including:

· Automatic replication of data

· Private VPN, monitoring tools, and robust SLA.

· Integration with other Amazon Web Services such as Data Pipeline and Kinesis.

· Payment of only the services and features that are being used.

· Security control due to Amazon’s IAN service.

Amazon DynamoDB is an excellent choice to pair with FHIR. It provides the query patterns and data representation required by the data repository.
