DIVOC Architecture

Highly flexible and configurable, DIVOC’s architecture is designed to accommodate changes and allow the addition of new capabilities and functionalities. For example, during a vaccination campaign, you can configure vaccines, vaccination frequency, approved facilities, trained vaccinators, certificate templates, and authentication mechanisms, among others. Built on open source and open standards, the DIVOC architecture ensures privacy and security by design.

Architecture highlights

Logical architecture

• DIVOC has been built using a micro-services architecture with open API integration capabilities. It can be hosted on the cloud and on-premise cloud.

• It is built on top of the generalised electronic registry and the credentialing framework is available under Sunbird Registry and Credentialing, as well as on-premise bare metal servers.

• DIVOC’s modules can work in various combinations based on a country’s requirements as well as end-user needs. Accordingly, countries can use specific or all micro-services.

Deployment architecture

• It is designed to plug and play with different certificate distribution schemes, such as printed with QR code, digital using smartphones, SMS/email attachments, digital lockers, etc.

• Allows interoperability with various ID, payment, and other systems.

Component architecture

• DIVOC is designed to cater to the diversity of use cases in terms of the choice of the facility (such as government and to private facilities) across geographies within a country; choice of payment (government funding, employer funding, or individual funding, among others); and choice of IDs (digital IDs, and mobile numbers.

• The platform is extensible. For example, many parts of the software can be extended, as well as replaced with country-specific components without having to customise. This, in turn, facilitates easy upgradability.
