With our Lizmap hosting service, we provide and monitor several hundred Qgis Servers. These Qgis Servers receive and process 5.2 million requests per week, including 4.8 million WMS GetMap requests.
We have developed Py-Qgis-Server to solve some of the problems we encounter: management of long-running requests, automatic restart, project caches, etc.
Py-Qgis-Server 2 has been designed for the cloud. It uses a microservices architecture with gRPC to control the various QGIS Server processes that handle OGC requests.
We'll look back at the initial need that led to the development of Py-Qgis-Server. We'll present the reasons for this rewriting, and finish with a look at the possibilities offered by Py-QGIS-Server 2.
