The DaVinci sandbox is an agile development environment run by Logica using a number of cloud-based service providers:

• Logica's Amazon Web Services (AWS) account in the us-east-1 (northern Virginia) region for most infrastructure services. (Note: Not GovCloud.)
• HL7 DaVinci's GitHub organization, in a number of repositories maintained by the DaVinci community at https://github.com/HL7-DaVinci
• Logica's Docker Hub organization, for delivery of server-side application images.

The AWS us-east-1 environment is used exclusively for this program. As it is shared with many other Logica efforts, management at the infrastructure level is limited to HSPC staff. The container management capability of Logica's enterprise architecture is used for the delivery and hosting of runtime services. Access for DaVinci developers is allowed, though requires a Logica ID and placement in the appropriate authorization group.

Resource Availability Requirements

The service level agreement between Logica and HL7 DaVinci essentially states that this environment will be made available to DaVinci stakeholders and end-users for development and testing purposes. It is not a production environment. In other words, the DaVinci sandbox:

• MUST facilitate rapid collaboration amongst developers and stakeholders around official use cases. (E.g. FHIR Connectathons) 
• SHALL NOT store nor operate upon PHI/PII.
• SHOULD be available during regular business hours.
• SHOULD NOT provide "high availability" (HA) qualities.

Application Types

DaVinci solutions primarily focused on FHIR and FHIR-oriented standards, i.e CDS Hooks and SMART-on-FHIR (SoF). From an operational perspective, this implies that individual applications are either server- or client-side artifacts, though both are built and deployed using the same Deployment Pipeline.
