API First
Everything can be and is done via open, powerful, and documented APIs. All business logic being separated from the user interfaces makes the G-REX API core very flexible, maintainable, and robust. One can easily build own user interface or integrate with back-end systems.
There is an API for every functionality of G-REX. Any user can by default access the G-REX functionality via the APIs directly.

Serverless Cloud Native
G-REX does not run on physical or virtual servers. It relies on already existing highly available and scalable cloud services. The needed infrastructure and configuration are set up automatically by code. The infrastructure-as-a-code (IaC) approach enables the deployment and testing of new G-REX instances in minutes. This means new domains can be deployed without a hassle and existing domains can be scaled very flexibly and to near unlimited capacity. G-REX Core uses the Platform as a Service components provided by Microsoft Azure.
Single-Page Application
G-REX App is a single-page application (SPA) ensuring extremely responsive and fast UI user experience. The SPA architecture allows all user data to be loaded in the background enabling near zero page load time experience to all but the heaviest reports and volumes.
The G-REX App stores the user customization choices, such as visible columns, their order and default sorts, locally so they are used when the user logs in next time. To feel the user experience, please click here.
The G-REX App runs on all modern browsers. The UI is built with Angular and it uses versatile and powerful Kendo UI components.

Resilience
G-REX services can be hosted in tens of datacenters across the globe. Georedundant services and backups enable high availability and low maximum data loss even in rare disaster scenarios. If, for example G-REX is hosted within the EU, the hosting including the georedundancy is configured so that all data always remain within the EU and no person outside of the EU can access the data.
